Route 5 near Seventh Street in Los Angeles to Route 1, Funston approach, and the
approach to the Golden Gate Bridge in the Presidio of San Francisco via
Santa Barbara, San Luis Obispo, and Salinas.
The road that became US 101 is one of the earliest state routes. It was originally recommended for the state highways map in 1896, and was adopted into the highway system in 1909. Construction began in 1912.
▸In 1963, this segment was segment (a) and (b), and was defined as the route "(a) The junction of Routes 105 and 110 in Los Angeles to Route 80 in San Francisco, passing near Ford Road south of San Jose. (b) Route 80 to Route 480." In this definition, "the junction of Routes 105 and 110 in Los Angeles" refers to the present-day I-10 east/US 101 junction -- the plan in 1963 was for those to be short stub interstates I-105 and I-110.
▸In 1968, Chapter 282 changed the definition of both segments. This
reflected two major changes. On the southern end, the stub definitions of
I-105 and I-110 were removed. What had been I-105, the portion of US 101
from the I-10 E junction to I-5, was added to US 101 (I-110, which was the
short stub from (present) US 101 to I-5/I-10, was added to I-10). On the
northern end, the freeway revolt in San Francisco was in flower, and
routes were changing everywhere. Portions of routes were switched between
I-480 and I-280 (and some of I-480 was deleted); changes were made to
I-80. As a result, both segments changed, and the new definition was: "(a)
The junction of Routes 105 and 110 Route 5 near
Seventh Street in Los Angeles to Route 80 near Division Street
in San Francisco, passing near Ford Road south of San Jose. (b) Route 80 near
Division Street in San Francisco to Route 480."
▸In 1991, Chapter 498 changed segment (b) to absorb former Route 480, making it "(b) Route 80 near Division Street in San Francisco to the junction of Route 1, Funston approach, and the approach to the Golden Gate Bridge in the Presidio of San Francisco passing near the intersections of Lombard Street and Van Ness Avenue." This brought Doyle Drive, which had been allocated to Route 480, back into US 101 (where it had been before the 1964 renumbering).
▸ In 1992, Chapter 1243 combined (a) and (b): "(a) Route 5 near Seventh Street in Los Angeles to Route 1, Funston approach, and the approach to the Golden Gate Bridge in the Presidio of San Francisco via Santa Barbara, San Luis Obispo, and Salinas."
Some Post-1964 Notes:
Some additional bit of history:
The following freeway-to-freeway connections were never constructed:
Central California (Santa Barbara through Monterey)
Buelleton Bypass. On June 10, 1965, the Buelleton
Bypass, extending from 0.7 mi S of the Santa Ynez River to 0.7 mi N of
Buelleton, opened. The project eliminated the last section of two-lane,
undivided highway on US 101 in Monterey County. US 101 in Buelleton proper
was previously a four-lane divided roadway running through the center of
town. It was flanked on both sides by frontage roads and interconencted at
grade with Route 246 and several other cross streets. The Route 246/US 101
Separation constructed as a part of the new freeway was one of the major
benefits of an immediate nature for the motorist. There were two
additional interchanges constructed. To the south is the Santa Rosa Road
Overcrossing and to the north, the North Buellton Overcrossing. All three
are diamond interchanges. In addition to these, the construction involved
building a four-lane divided highway with twin 1,000-foot box girder
bridges spanning the Santa Ynez River. The two separate roadways sit on a
common pier wall to allow for expansion at a later date to six lanes,
which can be done easily by the addition of a 12-foot lane to each deck.
Formerly, US, 101 had been restricted to two lanes by the old Santa Ynez
River Bridge. The transition from four- to two-lane traffic at the
old structure had proved a dangerous bottleneck for the high-speed
traffic. The completion of these two structures eliminated another
hazardous condition on the old highway. The portion of the old highway in
Buellton received a complete facelifting also. The former frontage roads
were widened to 42 feet, resurfaced, and restricted to one-way traffic.
Between the frontage roads is a 76-foot mall. This is to be landscaped by
the local businessmen's association in cooperation with the County of
Santa Barbara. When completed, this should give the center of Buellton a
decided parklike quality, which should be a pleasant improvement over the
traffic congestion of former years.

Prunedale Bypass. Improvements on US 101 in the
Prunedale area were identified in the 1960s when a project was initiated
to improve the corridor by constructing a new alignment that bypassed the
community of Prunedale. The California Highway Commission adopted
the US 101 freeway route on June 24, 1964. In April 1973, the Prunedale
Bypass was in the final design phase when it was determined that federal
funding could not be secured, and the project was delayed
indefinitely. In the late 1980s, the Prunedale Bypass was
re-initiated from a Measure B sales tax but lost funding again due to
challenges in court. As a result, the Prunedale Improvement Project
(PIP) in 2015 completed a series of operational and safety improvements,
such as upgrading the existing four-lane facility to a partially
access-controlled facility by constructing ten miles of median barrier,
two new interchanges, and a grade separation for a local street
crossing. The PIP was Phase 1 of the conversion to a fully
access-controlled facility. Phase 2 was planned as the Prunedale
Freeway on either the existing alignment or on the 1964 adopted bypass
alignment. By 2019, Phase 2 of the project was no longer identified in the
TAMC Regional Transportation Plan or any local or regional plans within
San Benito County. On March 26, 2020, the Commission approved Resolution
NIU 20-01 to notify all affected local, regional, and State agencies of
its intent to consider rescinding the freeway adoption. The Department
notified all affected local, regional, and State agencies of the
rescission proposal and asked agencies and the public for any additional
pertinent information that might be helpful to the Commission in making a
final decision. The Department completed the 60-day comment period
on March 19, 2021. Two public comments were received inquiring about the
process to purchase excess lands. The Department provided information
about the process to the interested parties. No other comments were
received from local and regional agencies or the State clearinghouse.
On April 6, 2021, TAMC reaffirmed their support for rescission of the
unconstructed portion of the freeway adoption.

Octavia Boulevard Project
Section 72.1 explicitly abandons as a state highway the portion of current Route 101 between Fell
Street and Turk Street. The portion of current Route 101 between Market
Street and Turk Street ceases to be a state highway unless the alternative
to the Octavia Street Project is approved in November 1999.
In November 1998, the voters adopted Proposition E,
which authorized the California Department of Transportation to replace
the Central Freeway with a new four-lane, two-way, single-deck elevated
structure from Mission Street to Market Street and a street-level,
four-lane boulevard along Octavia Street from Market Street to Fell
Street, with two additional lanes for local traffic (the Octavia Boulevard
Plan). Part of the land that was occupied by the Central Freeway and the
freeway ramps (the right-of-way property) was not needed to construct the
Octavia Boulevard Plan. The State Legislature then considered a bill that
would give the right-of-way property to the City. The City would have to
use any monies raised by sale or lease of the unneeded property first to
pay for the Octavia Boulevard Plan and then for transportation
improvements along routes leading to or from Octavia Boulevard. In
November 1999, Prop I was on the ballot. Proposition I is an ordinance
that called for using any proceeds from the sale or lease of the
right-of-way property—if the State gives the property to the
City—to fund the design and construction of the Octavia Boulevard
Plan and to use any remaining monies for transportation improvements along
routes leading to or from Octavia Boulevard.The City's Transportation
Authority would decide which transportation improvements to fund after
consulting with the Central Freeway Citizens' Advisory Committee and
following guidelines listed in the ordinance. Proposition I also would
call for development of residential and mixed residential/commercial uses,
including affordable housing, on the right-of-way property. The ordinance
would prohibit widening the existing elevated freeway structure between
Market and Fell Streets. City and neighborhood representatives would
participate in determining appropriate development of the right-of-way
property. This proposition passed: 54.10% Yes votes ...... 81,061 / 45.80%
No votes.
(Source: Smartvoter)
The Alternative Proposition mentioned, Prop J, would
have repealed Proposition E, authorizing Caltrans to retrofit and widen
the existing lower deck of the Central Freeway to provide a four-lane,
single-deck structure over Market Street from South Van Ness Avenue to Oak
and Fell Streets. The portion of the freeway between the intersection of
Haight and Octavia Streets and the Fell Street off-ramp would be replaced,
and a new on-ramp would be built at Oak Street. The measure also would
have directed the City to hold quarterly meetings on improving
transportation in San Francisco and to develop an annual comprehensive
transit plan. Proposition J provided that it could be amended or repealed
only by a two-thirds vote of the voters. 52.6% voted no and this didn't
pass, meaning that Section 72.1 went into effect, and the portion of US 101 N of Market Street ceased to be a state highway (and US 101 was
rerouted).
(Source: SmartVoter)
The Octavia Street Project took place in 2000, when
the elevated Central Freeway was removed north of Market Street (for a
time, there were the offramps down to Oak and Fell, but were also removed,
dumping traffic onto the new Octavia Blvd.), and the State transferred 22
parcels from under the freeway to the City. The San Francisco Office of
Economic and Workforce Development (OEWD) led the effort, on behalf of the
City, to smooth the transition from freeway to boulevard. The Octavia
Boulevard Project coordinated land use and transportation investments in a
way that secures long-term economic growth.
(Source: Octavia Project)
The history of the construction of the Central Freeway through Hayes Valley -- and the controvery associated with it -- is discussed in "The Birth And Life Of The Freeway In Hayes Valley".
As for what happened to what remains of the old US 101
in that area... it became a farm. Specifically, at the old on/off ramp
near Laguna Street in early 2010, a number of urban farmers spread
steaming piles of mulch over the edge of the ramps formerly used by cars
to enter and exit the elevated Central Freeway spur above Octavia Street,
arranging the soil in rows for planting vegetables and filler crops. This
has formed the "Hayes Valley Farm". The farm closed in 2013.

Central Freeway portion [Route 80 (~SF R4.307R) until the freeway portion ends (~ SF M5.442)]
In October 2022, it was reported that the Central
Freeway portion [from Route 80 in San Francisco (~SF R4.307R) until the
freeway portion ends (~ SF M5.442)] (or a portion of that portion) was
being painted "Coronado Blue". Specifically, work crews are coating the
undergirding of the elevated roadway that connects Market Street to US 101
in a new eye-catching Coronado Blue. Started in June 2021, the project is
expected to be done in May 2024. It’s on budget and will cost a
total $30.9 million. Built in 1955, the entire Central Freeway was damaged
by the 1989 Loma Prieta Earthquake. Only the portion made of concrete west
of Market Street was torn down. The remaining steel stretch was
retrofitted and reconstructed in the early 2000s. A group of activists
want the freeway to be torn down from Market to Bryant streets and
replaced with a grand boulevard and housing. Conducting a study to that
effect is mandated in the city’s Master Plan, the blueprint for its
growth, but it has yet to be completed. A review of the Federal Highway
Administration inspection reports show the freeway is in fair condition.
Inspectors found two issues—known as deck geometry and
underclearance—to be “intolerable” and requiring
“high priority corrective action.” Neither of these is an
indication that the nearly two-mile long viaduct is inherently unsafe, but
those features do not meet modern design standards.
(Source: San Francisco Standard, 10/25/2022)
In December 2022, it was reported that State Sen. Scott
Wiener (D-San Francisco) formally asked the California Department of
Transportation to study the cost and logistics for taking down the Central
Freeway, the Bayshore Viaduct of I-80 between 17th Street and
the Bay Bridge, and I-280 north of US 101. The letter, cosigned by a dozen
advocacy groups, adds momentum to a small but growing campaign to remove
some of the city’s freeways. Caltrans is working on a response to
Wiener. The belief of the proponents is that removal would help Caltrans'
budget, potentially make way for housing and open space, and better
connect Mission Bay with the city center.

There are some planned freeway routings in the city of San Francisco. California Transportation Commission (CTC) Agenda Item June 2000 2.3a discusses a route from PK (Post Kilometer) 7.6 at South Van Ness to PK R8.2 at Fell Street. July 2000 Agenda Item 2.3a discusses a route from PM R5.0 at Eire Street to PM 5.3 at Golden Gate Avenue.
Golden Gate Bridge (SF 9.899 to MRN L0.261)
Note that the Golden Gate Bridge is not part of US 101. The Golden
Gate is maintained by the Golden Gate Bridge, Highway, and Transportation District. This gap dates back to the original gap in State Highway Maintenance between LRN 1 (the
Redwood Highway) and LRN 2 (El Camino Real). This gap originally included
the City of San Francisco, as state highways prior to 1933 did not
traverse cities. However, the US highway designation did, and US 101 did
include San Francisco, starting from the Hyde Street Pier. The planned
designation of US 101 (which was independent of the state legislative
routes) also included the ferry from Sausalito to the Hyde Street Pier.
(Partial source: Gribblenation Blog (Tom Fearer),
“The Legislative Route gaps of US Route 101 and California State Route 1 on the Golden Gate Bridge”, 11/2021)
In January of 1933 construction of the Golden Gate Bridge began followed
by construction of the San Francisco-Oakland Bay Bridge in July
1933. This, combined with the extension of state highways into
cities, led US 101 to be extended through San Francisco from the pier, and
to include a diversion to the Bay Bridge (where US 101E split off and went
down the East side of the bay, with US 101W on the west). Additionally, in
1933, LRN 56 (Route 1) was extended into San Francisco, although not
across the bay.
(Source: Gribblenation Blog (Tom Fearer), “The Legislative Route gaps of US Route 101 and California State Route 1 on the Golden Gate Bridge”, 11/2021)
The Golden Gate Bridge was completed on April 19, 1937 and was dedicated
on May 28th. Unlike the state-built San Francisco-Oakland
Bay Bridge, construction of the Golden Gate Bridge was financed by the six
Counties of San Francisco Bay and was not a State Highway facility.
The Golden Gate Bridge features a 8,980 foot long hybrid truss-suspension
design. Despite not being a state highway, US 101 appears to have been
aligned across the bridge per AASHTO documents, even if there was not
state maintenance.
(Source: Gribblenation Blog (Tom Fearer), “The Legislative Route gaps of US Route 101 and California State Route 1 on the Golden Gate Bridge”, 11/2021)
This continued with the 1964 renumbering, where the definition for new Route 101 (US 101) excluded the bridge.
US 101 was part of the original set of planned US routes
in 1926, and was first signed in 1928. The route existed long before the
signing, however. It began at the Mexican border, and ran N through San
Diego along National Avenue, Main St., Harbor Drive, Pacific Drive, Midway
Drive, Morena Blvd, and Pacific Coast Highway (the route from National
City/San Diego N was LRN 2, defined in 1909; it was extended to the
Mexican border in 1931). Both were essentially following a routing
established by El Camino Real. The US 101 routing was later bypassed by
the present-day I-5 (Montgomery Freeway). SignOnSanDiego has noted
there is an oral-history project recording memories of old US 101. There's
a Historic US 101 sign on San Diego Ave. in the Old Town section, near the
Whaley House. Also, street names like "Old Hwy 101" and "Coast Hwy 101"
follow the old route in Solana Beach and Encinitas. Other streets on the
original route included Turquoise Street, Cass Street, Garnet Avenue,
Morena Boulevard, San Diego Avenue, India Street, Harbor Drive, Broadway
in Chula Vista and Beyer Boulevard in Otay Mesa.
This alignment, along Torrey Pines and La Jolla Blvd., was once signed as US 101W. The later I-5 alignment, the Rose Canyon Highway, was signed as US 101E.
The original US 101 was replaced relatively quickly in 1933 by the more
modern and direct Pacific Highway featuring bridges and ramps, which kept
the name US 101 despite following a significantly different route than the
original version. City officials debated for several years whether to
build a north-south route along the coast through Pacific Beach and La
Jolla, or to build a more direct route through the rugged and hilly
terrain of Rose Canyon to the east. They eventually chose the coastal
route based on its flatness and scenic beauty, and paving was completed in
1920 of La Jolla Boulevard, Turquoise Street, Cass Street and Garnet
Avenue. But the shorter Rose Canyon route, which some travelers had used
before the Pacific Beach route had been paved, was flattened a bit and
rerouted in 1930 with a big plan on mind. City officials decided to create
a new US 101 by grading and extending Atlantic Street from Barnett Avenue
to the Rose Canyon highway at Balboa Avenue, and re-naming it Pacific
Highway. The road was designated as the new US 101 in San Diego when it
opened in late 1933, and it was connected to the state’s portion of
US 101 that had been completed all the way to just south of Del Mar. In
1935 the city officially changed the names of Atlantic Street, West
Atlantic Street, Rose Canyon Highway, Torrey Pines Mesa Road and Torrey
Pines Road to Pacific Highway. The road was eventually connected to the
South Bay and the border in the 1950s with construction of the Montgomery
Freeway. A few sections of the old Pacific Highway still exist, including
a long stretch from downtown up to Mission Bay Park where you can see the
road’s old-fashioned highway interchanges. The road also still
exists from where it began near present-day Seaport Village through the
northern edge of downtown. A few other sections have survived, such as
North Torrey Pines Road between UC-San Diego and Del Mar, Gilman Drive
between I-5 and the university, and Mission Bay Drive in Pacific Beach. In
contrast, nearly all of the original US 101 has survived, of course,
because it was essentially surface streets. Missing portions, however,
include a chunk that became part of the UCSD campus and a stretch
eliminated to create the National City Mile of Cars. In addition, part of
the original US 101 isn’t open to the public because it’s
within Marine Corps Base Camp Pendleton. There is evidence the original US 101 split into two separate routes for a few years because of congestion
concerns, but details of that are disputed. The western route may have
included Ingraham Street and Foothill Boulevard. And the later version of
US 101 was divided into two routes in North County, between Palomar
Airport Road and Route 76, for the same reason in the 1950s. [Note: It is
unclear how this articles description of the split connects with US 101W
and US 101E]
(Source: San Diego U-T, 8/18/2017)
From San Diego, the route ran N along Pacific Coast Highway to San Juan Capistrano. This route is now San Diego County Sign Route S21. The old "El Camino
Real" is San Diego County Sign Route S11. This has been bypassed by I-5, and was LRN 2.
Other portions that were onced signed as US 101 include Carlsbad Blvd, San
Diego County Sign Route S6, San Diego County Sign Route S8. This is one of the older freeway segments in
the San Diego area, encompassing the former Carlsbad Freeway, and including a Business Routing for US 101 in Oceanside. A
California Highways and Public Works magazine from 1925 notes that the original pavement was first placed in service around 1912, with 15' wide by 4" thick
concrete. A relocation project occurred in 1924, which widened the
pavement, relocated 7 miles, and eliminated 2 grade crossings.,
Between this point and Oceanside, I-5 buries the old road. Between San Juan Capistrano and Oceanside, the following is a description of how to find the old road (alias, it goes from N to S, while the rest of this paragraph goes from S to N):
South of San Juan Capistrano, you can follow US 101 pretty closely on Camino Capistrano then continuing south on the Old Coast Hwy which then turns into El Camino Real through San Clemente. You will have to get back on the freeway at Christantos. Then you can take Baslone Road and turn right, you will be on the Old Pacific Hwy and if you can do it, when your making the sharp left turn after the Fwy take a look right and you can see the old Expressway thats now buried by I-5. Continue south on the old expressway, over the railroad overpass and past San Onofree Nuclear Power Station until you get to the entrance to the San Onofree State Beach. Pay the ranger and continue on. Now eventually you will have to get on a bycycle to continue further south, when the Expressway gets to area below the Vista Point this is point where I-5 buries the old road all the way to Oceanside.
With respect to the route through the Marine base, US 101 was open
through the base, all the way to San Diego. It was only four lanes divided
through the base, with a 60mph speed limit. The accident rate was high.
Portions of the original road still exist south of Camp Pendleton down to
San Diego, with historic US 101 markers. Within the base, the northern
part of the old road still exists, as a service road to San Onofre State
Beach and the nuclear power plant. Most of the rest was incorporated into,
or obliterated by, I-5, or still exists as a bike trail.

Note: For a detailed history of past US 101 routings, see Historic U.S. 101 - Los Angeles County, written by Scott Parker, over on AARoads.
From San Juan Capistrano, US 101 ran N through El Toro and Irvine to Santa Ana. From Capistrano Beach, it ran along Laguna Road (since overlain with US 101, and then I-5) to 1st Street, then Main Street (Santa Ana), across Chapman to Lewis running N/NW to roughly what is now Anaheim and Katella (after 1937, this may have been long the completed extension of Manchester) (roughly where it met LRN 174, Manchester, which was overlain by US 101/I-5), Los Angeles St (renamed after 1970 to Anaheim Blvd), across what is now La Palma Parkway (previously Los Angeles St.) and Spadra (renamed in 1967 to Harbor Blvd). It ran N on Spadra/Harbor to Fullerton Road (later renamed Harbor Blvd), and along Fullerton Road (Harbor Blvd) to Whittier Blvd, and W along Whittier Blvd into Los Angeles County to Mission Road. It ran N along Mission Road to Sunset Blvd. This portion of the routing has been bypassed by I-5.The freeway routing was part of LRN 174 from Rosecrans and Firestone (Route 42) to Santa Ana; otherwise, it was LRN 2.
It appears there were, at one time, plans to extend LRN 2 (probably not as US 101) along Whittier Blvd, then a bit to the S to eventually meet Deodara (which became Lambert) to join up with LRN 19 near what became State College. This was to support the eventual post-1964 Route 57.
It may have taken, at one time, a different route through Norwalk, as there is an El Camino Real bell at the intersection of Orr and Day and Imperial. In terms of LRNs, the freeway routing of US 101 S was LRN 2 (defined in 1909) from San Diego to a point S of Anaheim, LRN 174 (defined in 1933) from Anaheim to Route 35, and LRN 166 (defined in 1933) into downtown LA. The surface street routing ("old US 101") was LRN 2 at this point, and was likely signed is "Business US 101". It is present-day Route 72. For a short time, there was also a Bypass US 101 running from the intersection of Firestone Blvd / Manchester Ave. and Los Angeles St, northwest along Firestone (pre-1964 Route 10), N along Lakewood Blvd. (Route 19), W at Anaheim Telegraph Rd (Route 26), N to Whitter Blvd at Calzona St.
In 1952, the CHC revealed plans for the freeway routing
in the San Juan Capistrano area. The route roughly follows US 101 from
Niguel Road to a point about 1 mi N of Capistrano Beach. It bypasses San
Juan Capistrano to the east. It then proceeds inland from the present
Coast Highway to San Clemente, crossing the Coast Highway new W Avenida de
Los Lobos Marinos in that city. Thence it goes S of the present highway.
The plan was to construct a 4-lane facility expandable to 6 lanes from
Niguel Road to San Clemente, with 6 lanes after that. There would be a
connection with the Pacific Coast Highway from Serra Junction to a point
near Capistrano Beach.

An August 1941 report issued by the Regional Planning Commission of Los
Angeles County entitled “A Report on the Feasibility of a Freeway
Along the Channel of the Los Angeles River” proposed a
four-lane roadway on each levee from Anaheim Street in Long Beach north to
Sepulveda Boulevard in the San Fernando Valley; excepting between Soto
Street and Dayton Street in downtown Los Angeles, where, due to a lack of
right-of-way along the river, the alignment matches the future alignment
of the US 101 portion of the Santa Ana Freeway. There is no mention in the
report of a master plan of freeways like that issued in 1947, although the
maps showed connections to the already-completed Arroyo Seco Parkway and
the proposed Ramona and Rio Hondo Parkways.
(Thanks to Daniel Thomas for hunting down this
information)
Whittier Blvd and US 101 Bypass
Prior to the freeway routing that became I-5, US 101 ran along Whittier Blvd and up towards Sunset Blvd and East Los Angeles.
By 1915, LRN 2 had been completed from the Los
Angeles/Orange County line to Anaheim to State standards. A 1917 map shows
LRN 2 following Whittier Boulevard, Spadra Road and Los Angeles Street
from the Los Angeles city limit to Anaheim, passing through the
communities of Montebello, Whittier, La Habra and Fullerton. The
route along Whittier Blvd was widened in 1924. In 1925, a new bridge was
constructed over the San Gabriel River, opening in 1926. In 1925, LRN 2/Whittier Boulevard was expanded from Montebello to Workman Mills Road in
Whittier. In 1926, the Rio Hondo Bridge along LRN 2/Whittier Boulevard was
moved 15 feet upstream to a new alignment, allowing the structure to be
twinned. In 1927, the expansion of US 101/LRN 2/Whittier Boulevard from
Michigan Avenue to the Orange County line was completed. By 1935, the
routing of US 101 was approaching Whitter Boulevard via Boyle Avenue in
Los Angeles. From Los Angeles, US 101/LRN 2 followed Whittier
Boulevard to La Habra in Orange County via Montebello and Whittier.
US 101/LRN 2 departed La Habra via Spadra Road towards Anaheim via
Fullerton, passing through Anaheim via Los Angeles Street south towards
Santa Ana.

By 1942, work on US 101 Bypass had begun with the
transformation of Sign Route 26.. The 1942 Division of Highways Map shows
Sign Route 26 with a gap originating at the eastern terminus of LRN 173 at
Indiana Street in Los Angeles. Much of what had been Sign Route 26
on Anaheim-Telegraph Road (LRN 166) was designated as US 101 Bypass.
From Anaheim-Telegraph Road, US 101 Bypass followed Lakewood Boulevard
(LRN 168), Firestone Boulevard (LRN 174) and Manchester Boulevard (LRN 174) to Anaheim. Mainline US 101 followed Whittier Boulevard, Spadra
Road and Los Angeles Street between Los Angeles-Anaheim. By the end of
1952, US 101 Bypass would be completed between Rosemead Boulevard and the
Los Angeles Civic Center, with motorists using Lakewood Boulevard and
Firestone Boulevard east of Rosemead Boulevard to Norwalk. By 1953, the
Bypass was complete to Slauson, and by 1954, to Pioneer Blvd near Norwalk.
At this time, mainline US 101 was realigned onto the Santa Ana Freeway
(LRN 166), an interim routing on Pioneer Boulevard and Firestone
Boulevard/Manchester Boulevard (LRN 174) between Los Angeles to
Anaheim. The former mainline of US 101 on LRN 2 was no longer signed
as US 101. In the 1964 renumbering, former US 101 on LRN 2 was renumbered
as Route 72 between I-5 and new Route 245 (Downey Road).

In 1937, the final segment of the "Manchester Boulevard
Extension" was dedicated. The Manchester Boulevard Extension
provided a direct link between Downey and Anaheim that followed the
Southern Pacific Railroad. The Manchester Boulevard Extension
bypassed downtown Anaheim and tied into existing alignment of Sign Route 10 (LRN 174) on southern Manchester Boulevard at Miraflores near the
outskirts of Santa Ana. The Manchester Boulevard Extension was
initiated in 1924 by the Greater Manchester Avenue Improvement
Association. The Manchester Boulevard Extension concept was taken
over by the Division of Highways when LRN 174 was added as a State Highway
around 1933. Manchester Boulevard in Anaheim would appear as part of
US 101 Bypass on the 1940 Division of Highways Map and would become part
of mainline US 101 in 1953.

East LA Interchange
The portion in the downtown area (between the Route 110 (former Route 11/US 66) interchange and the Route 60 interchange) was signed, between 1947 and 1958, as US 99/US 101/US 60/US 70.
Scott Parker on AAroads provided an interesting history
of the East LA Interchange:
(Source: Scott Parker on AARoads, "Re: What about the capacity (capacitibility) of the East Los Angeles Interchange?", 7/14/2016)
From about '58 to '67 parts of it were literally carved out of the L.A. river bluffs and local neighborhoods — it, and the various freeway branches extending outward from it could serve as the "poster child" for the concept of constructing freeways through neighborhoods where the cost of property acquisition was relatively miniscule. The basic location was determined by the presence of the original US 101 "Santa Ana" freeway; the section of the interchange's location was opened by 1947. When it was decided to route I-5 between central LA and points to the south along this facility, it became only a matter of choosing just where to place the interchange with the "Golden State" freeway (I-5 north/I-10 east) and the Santa Monica freeway (I-10 west). The basic Interstate portion of the interchange (at that time, US 101 from the interchange north to the west terminus of the San Bernardino Freeway was designated, but never signed as, the original I-105) was completed in late 1962 with the opening of the first section of the Santa Monica/I-10 freeway to the west. Originally, "ghost ramps" essentially continuing the trajectory of the Santa Monica freeway eastward just north of the Santa Ana Freeway could be seen; they became the western terminus of Route 60, the Pomona Freeway, which opened in the spring of 1967. There's not a lot of room for this interchange to grow -- the east I-10 to I-5 south and Route 60 connection is located on a bridge structure that begins about a half-mile west as the L.A. River crossing, and continues east until the rising ground of the river bluff is encountered; that segues quickly (a couple hundred yards) to the ramp to south I-5 and then a series of bridges over I-5 and the interchange's easternmost ramps. Without major bridge reconstruction and/or taking of nearby property, there's no place to readily increase capacity here. Westbound is essentially the mirror-image of this; traffic from west Route 60 to west I-10 is down in a trench under I-5 and several local streets before rising up to join the main I-10 lanes and bridge the river westward. The I-10 through lanes are also on a series of bridges, crowded in by industrial facilities or topographical features. Again, not a lot of room to grow -- there are businesses, including the LA Times printing plant, situated right along the edges of either the aforementioned eastbound bridge or the westbound trench.
This interchange is a perpetual traffic nightmare; its traffic levels have exceeded its planned capacity several times over — but, as with many urban facilities, the cost (financial and social) of significant expansion is prohibitive. It's lucky that the original concept was squashed by the time interchange construction commenced; that concept saw another freeway extending directly south (a virtual extension of the Golden State freeway) called the Industrial Freeway (Route 258), which continued south to Terminal Island; this, after 1964, morphed into the Route 47 corridor, the northern reaches in central LA of which never progressed beyond an undefined-alignment line on the state planning maps. Route 47 presently only extends north from Terminal Island as mostly a surface facility (much of which follows Alameda Ave.) but only as far as Route 91. The concept of a freeway along that corridor (principally as a relief route for I-710 to the east and I-110 to the west) has been jettisoned; its place as a commercial traffic conveyor has been taken by the freight-rail Alameda Corridor from the port area to the rail yards east of downtown LA.
Scott Parker (Sparker) also added the chronology of construction:
The first sections to be completed, in early 1961, were the ramps forming the direct I-5 connection, from the SE Santa Ana Freeway (at that time still signed as US 101) to the Golden State Freeway (I-5/I-10). The San Bernardino Freeway interchange a couple of miles north on the Golden State had been completed and opened in early 1960 (and, for a while, there was a BGS on westbound I-10 just before that interchange showing the through lanes of the San Bernardino Freeway as I-110; it was gone by 1963). Until the I-5 throughput ramps were opened, the freeway temporarily terminated at Boyle Ave. near Hollenbeck Lake. The I-10 through ramps from the Golden State to the westerly Santa Monica freeway opened right around Christmas of 1961; it simply directed traffic to Santa Fe Avenue (and were temporarily signed as such, minus any I-10 reference). The entire Santa Monica viaduct south of downtown LA was completed to the Harbor Freeway (then US 6/CA 11) in late 1962; the ramps from the SE Santa Ana Freeway to the Santa Monica were opened at that time as well; all signage clearly indicated I-10. The multiplex of I-5 and I-10 was acknowledged by a roadside BGS northbound; the only freestanding signage featuring both I-5 and I-10 shields was southbound immediately after the WB I-10 merge from the San Bernardino Freeway; that signage lasted several years but was gone by the late '60's.

There is loads and loads of detail on the different routings of US 101 / LRN 2 through Los Angeles -- far too many to include here. This discussion over on AAroads summarizes it in gory detail.
Routings Through Los Angeles
It appears that the original routing of LRN 2 was to be
as follows (this was likely not signed as US 101):
(Source: AARoads:Historic U.S. 101 - Los Angeles County)
In 1929, there was an alignment shift downtown:
(Source: Gribblenation Blog - Hollywood Freeway; California State Route 170, US Route 101, US Route 66 and California State Route 2; Scott Parker (Sparker) on AARoads)
In 1930 (before the state highway system signed routes
in cities), the LA City Council requested the routing to be: From the
southern city limit of Los Angeles at Whittier Boulevard, US 101 was to be
signed following Boyle Avenue, Pleasant Avenue, Macy Street (now Cesar
Chavez Avenue), Main Street, Sunset Boulevard and Cahuenga
Boulevard. US 101 was to follow Cahuenga Boulevard via Cahuenga Pass
to San Fernadno Valley and Ventura Boulevard.
(Source: Gribblenation Blog (Tom Fearer), "The history of US Route 101 in Los Angeles", 7/1/2023)
In 1934-35, the alignment shifted again:
(Source: Gribblenation Blog - Hollywood Freeway; California State Route 170, US Route 101, US Route 66 and California State Route 2; Scott Parker (Sparker) on AARoads)
Before the construction of the freeway in Los Angeles, US 101 ran W along Sunset to Cahuenga, N along Cahuenga to Ventura Blvd, and ran out of Los Angeles on Ventura Blvd. Ventura Blvd is the oldest continuously traveled route in the Valley. Originally part of the famed El Camino Real, the dirt path between between California's Spanish missions, it has been known as Camino de las Virgenes and Ventura Road.
Conversion of US 101 to the Hollywood Freeway
Construction of US 101 as freeway through downtown Los Angeles started in 1949, reduced Fort Moore Hill to a stump and converted the section of Broadway between Temple and Sunset from a tunnel to a freeway overpass. This had the side effect of removing the Fort Moore Hill tunnel. The freeway's construction also doomed the Hill Street tunnels, although the second tunnel through Fort Moore Hill would survive until 2004 as storage space for the Los Angeles Unified School District's archives. Information on the tunnels in downtown LA, including pictures, may be found here. Details on the construction may be found in the 1950 and 1951 issues of CHPW.
Public reception of the Hollywood Freeway was not
always positive. Early planning maps showed the Hollywood Parkway (to use
its original name) slicing through a densely populated area. Residents
were understandably unsettled. As early as 1940, the Hollywood
Anti-Parkway League denounced the Cahuenga Pass Parkway, then under
construction, as “un-American.” Later, as planners moved to
extend the parkway toward downtown, opposition became even louder. Movie
stars worried about their Whitley Heights homes. Merchants fretted about a
sweeping concrete viaduct over Franklin Avenue. The Hollywood Bowl
Association feared noise pollution. Some critics suggested that the city
build a rapid transit line instead. Most supported the general idea of a
freeway but disagreed with its routing. Ultimately, the state relented to
local opposition and struck compromises with the mostly white,
middle-class, and politically powerful Hollywood community. Construction
claimed several historic structures, including Charlie Chaplin's and
Rudolph Valentino’s former homes in Whitley Heights, but the state
planted extensive landscaping near the Hollywood Bowl to dampen traffic
noise, and highway engineers bent the freeway around local landmarks like
the First Presbyterian Church, the Hollywood Tower apartments, and
KTTV’s newly constructed television studio. Construction lasted
seven years (1947-54) and cost $55 million. Nearly half went toward
right-of-way acquisition, which involved the relocation of 1,728 buildings
and the demolition of another 90. [See the Source link for some wonderful

The Gribblenation Blog (Tom Fearer) "The history of US Route 101 in Los Angeles" provides a lot of detail, including timing for the construction of freeway segments, for US 101 and the Hollywood Freeway, including the Santa Ana and East Los Angeles portions.
There was once an off-ramp at Boylston Street (~ LA 1.905) on SB 101, as shown in a 1954 map
and a 1962 image posted to the Facebook Group Freeways of Los Angeles.
The units on the west side of Boylston were constructed in 1922. and
remain as of 2023. Based on that, the exit ramp from the US 101 to
Boylston was very narrow, with a sharp exit at the end. Note that there
was no onramp at this point as it would be in the middle of the
interchange; nor was there anything on the NB side of US 101. It appears
to have been removed in a subsequent freeway widening. The original ramp
edges remain as evidence of the ghost ramp.

The Planned Interchange with the Beverly Hills/Glendale Freeway
A 1954 issue of CHPW confirms that the widening of US 101 near Vermont was in anticipation for the future Route 2 freeway (LRN 162, called, at that time, the "Santa Monica Freeway" as it ran along Santa Monica Blvd, vice LRN 173, the Olympic Freeway (Route 26), which eventually became I-10): "The design finally adopted for the Hollywood Freeway at the crossing. with Vermont Avenue was influenced by the contemplated future construction of the Santa Monica Freeway and also the possibility of rail rapid transit facilities being installed on the future Santa Monica Freeway. This required the lengthening of the Vermont Avenue Bridge and other bridges in the vicinity. The added cost providing for future rail rapid transit facilities was financed by the City of Los Angeles from city funds. Similarly financed from city funds were the bus transfer facilities at Alvarado Street and Vermont Avenue and Western Avenue."
According to Scott Parker on AARoads: Even back in 1953
when it was constructed, the Hollywood Freeway featured the lane
separation near the Melrose exit that was intended to accommodate LH ramps
to and from the Glendale/Beverly Hills Freeway in a similar fashion to the
present I-5/I-710 interchange in the City of Commerce (itself a holdover
from '50's design standards). The Glendale Freeway was completed to its
present Glendale Blvd. terminus back in 1962; plans were active to extend
it to US 101 as late as 1975, but those plans were put on hold when
Adriana Gianturco became Caltrans' chief that year and drastically
curtailed freeway planning and building statewide. Eight years later, when
administrations changed along with agency mission, the Echo Park/Silver
Lake area through which Route 2 would have run had become quite
gentrified, resulting in NIMBY opposition that was echoed within L.A. city
government. At that point the freeway extension was effectively dead. But
the simple truth is that even if that segment connecting to US 101 had
been built, the regional politics had shifted enough that a western
extension through the south part of Hollywood and into Beverly Hills would
be D.O.A. as well. Given the trajectory of the adopted Glendale Freeway
alignment and the configuration of the originally planned US 101/Route 2
interchange, the traffic from Route 2 would have simply segued onto NB US 101 -- which, unless immediately departing the Hollywood Freeway in its
namesake neighborhood, would have been duplicative of other freeway
service (i.e., Route 134). Given all that, the final decision to scrap the
freeway extension was hardly surprising.

Cahuenga Pass Parkway
The Cahuenga Pass Parkway concept was developed by City Engineer, Lloyd Aldrich. Aldrich's plan include four lanes in each direction, with separation between opposing traffic flows with the Pacific Electric Railroad tracks in the middle. Bridges connecting the service roads and spanning the parkway were constructed at the Pilgrimage (now John Anson Ford) Theater, Mulholland Drive and Barham Boulevard. At the southern end of the Pass, southbound traffic destined to Highland Avenue would stay to the right, while traffic destined to southbound Cahuenga Boulevard would stay in the left two lanes and travel in a tunnel under the Pacific Electric Railroad tracks. The first unit was opened on June 15, 1940 and extended northerly to the Barham Boulevard ramps. By January 1, 1941, the roadway was extended to terminate in a 90° curve connecting with the older segment of Cahuenga Boulevard near Bennett Drive. Cahuenga Boulevard Parkway, a freeway less than two miles long, was opened just one day after the Arroyo Seco Parkway was dedicated. The next phase of extending the parkway to the intersection of Ventura Boulevard and Vineland Avenue was disrupted by World War II, and was completed by the State in 1949. In 1954, Cahuenga Parkway was altered and incorporated into the Hollywood Freeway. This route was LRN 2, started in 1909.
While the last phase of the Cahuenga Parkway was being
completed, work already was underway on building the Hollywood Freeway.
The last segment of the freeway, built in 1954, connected to the south end
of the original Cahuenga Parkway. The completion of the Hollywood Freeway
necessitated the demolition of the 1940 tunnel connection under the
Pacific Electric Railroad tracks between the Pilgrimage bridge and Odin
Street (you can find a nice history of the Pilgrimage Bridge here). In addition, since the Pacific Electric Railroad had ceased operation in
1944, the area that it had occupied in the median was reconstructed to
accommodate traffic from northbound Highland Avenue. In 1957, when the
Hollywood Freeway was extended northwesterly of Lankershim Boulevard, the
northbound on-ramp, northbound off-ramp and southbound on-ramp at Barham
Boulevard were abandoned. The abandoned ramps have remained preserved
since that time. Despite alterations, much of the original Cahuenga
Parkway remains intact. The original ornamental street lights on the
bridges still look charming. The Pacific Electric Railroad overhead cable
hooks can still be seen on the bridges over the area formerly occupied by
the tracks. And the ornamental design in the corners of Barham Boulevard
bridge remains. [The southbound off-ramp at Barham Blvd. was closed in
2015]
(Source: The historical information above on the
Cahuenga Pass Parkway was derived from "Transportation Topics and Tales: Milestones in Transportation History in Southern California" by John E. Fisher, P.E. PTOE)
The first unit of completed construction on the freeway
was between Highland Avenue and Barham Boulevard in the Cahuenga Pass,
opened to traffic in 1940. Further construction on the project was delayed
until additional state highway funds could be procured under the
Collier-Burns Highway Act of 1947. On September 4, 1948, Lankershim
Boulevard opens to traffic under a newly completed Hollywood Freeway
overpass as part of the “Barham-to-Vineland” segment of
US-101. The second unit of US 101 was completed in November, 1948
(outbound) and January, 1949 (inbound), from Barham Boulevard to Vineland
Avenue in the San Fernando Valley. Much of the construction involved
overpass accommodation for both the Pacific Electric rail lines and six
lanes of freeway. Pacific Electric lines ran in the median of the freeway
through the Cahuenga Pass until December 28, 1952 when the line was
abandoned in favor of bus service. On December 27, 1950, the 2.5-mile
stretch between Grand Avenue and Silver Lake Boulevard, opened to traffic
following dedication ceremonies. This section of freeway includes the
4-level grade separation structure at the junction point of the Hollywood
Freeway and Arroyo Seco Parkway, although only the highest level of the
4-level was in use at the time. On December 20, 1951, the Hollywood
Freeway opened through the LA Civic Center. At the time, Highway
Commissioner Harrison R. Baker stated that: "This is a short but vital
link of the Hollywood Freeway — in fact it is probably the most
important link in the entire system of freeways. Not only does this link
complete the five miles from Western Avenue but it gives a connection with
the Ramona and Santa Ana Freeways. In addition, this link gives a good
distribution of traffic from these three freeways into Downtown Los
Angeles." The final section of the Hollywood Freeway was opened on April
15, 1954, with dedication ceremonies featuring actor Bob Hope.

The First Soundwall
The proximity of the Hollywood Bowl also led to the
first soundwall, although it wasn't constructed on US 101. After the
two-mile long Cahuenga Pass Freeway opened in 1940 near the Hollywood
Bowl, concertgoers and residents started complaining about traffic noise.
So, in 1945, the California Department of Public Works conducted a noise
study, which recommended building a 10-foot high wall to block the traffic
noise. But the wall wasn't built and noise complaints grew as the entire
Hollywood Freeway was opened several years later, clogging the road with
183,000 vehicles a day — almost double the volume it was designed to
carry. The state highway department conducted additional studies regarding
the problem of freeway noise at the Bowl and later recommended building an
even taller 30-foot tall wall. These early studies helped lay the
foundation for freeway soundwalls. In 1954, L.A. Mayor Norris Poulsen
appointed a committee to study the noise caused by the 101 Freeway.
According to L.A. City Council records from that time, the city's general
manager recommended developing a sound barrier consisting of high
vegetation to screen the Hollywood Bowl. But instead of building the wall,
city records show officials decided to crack down on cars without
mufflers, hoping they could prevent excessive noise. A new city job was
created: Motor Vehicle Muffler Inspector. The city ordinance creating the
job position noted that the noise caused by the 101 Freeway threatened
"the peace, health and safety of persons living in areas adjacent to [the]
Freeway." Meanwhile, Hollywood was also complaining about freeway noise.
Movie studios worried that it would interfere with filming. In 1956, the
state Department of Public Works conducted a study of freeway noise at the
Columbia Pictures Ranch in Burbank — now Warner Bros. Ranch —
where dozens of movies and television shows have been filmed, including I
Dream of Jeannie and Bewitched. And the complaints kept coming. As more
freeways were built, more people complained about the noise. Then in 1968,
the California Department of Public Works built what is believed to be the
state's first official freeway soundwall on I-680 in Milpitas, near San
Jose.

Plans for US 6 Co-Signage
With the planned construction of the "Hollywood Freeway
Extension" along future Route 170, plans were made to reroute US 6 off US 99 (future I-5) and down Route 170 and US 101 into Downtown Los Angeles.
US 6 was briefly signed (as shown by Michael Ballard's site) along the constructed southern end
of the extension in 1962, with signs leading up to and at the interchange
with US 101/Route 134. That signage went away with the truncation of US 6
in 1963. There is no evidence that US 6 was signed along US 101; that was
likely pending complete signage S from I-5 (with temporary signage along
Lankershim while Route 170 was under construction). Said signage never
happened.
(Source: Michael Ballard, email and website, 7/16/2020)
US 101 in the San Fernando Valley
In mid-1962, the Hollywood Freeway was extended to Vineland and Magnolia in N. Hollywood, with traffic using it as far as Magnolia Blvd. Further, a project was started to widen the original Hollywood freeway between Sunset and Pilgrimage Bridge to make it a uniform 8-lanes between downtown and the valley. Also in 1962, the route was made continuous from the Hollywood Freeway to the Golden State Freeway... to the east (the extension to the north was still under construction). This occured with the completion of the projects between the Hollywood Freeway and Buena Vista Street, and between Buena Vista Street and the Golden State Freeway, five miles, completed at a combined construction cost of $10,436,000.
On 11/18/1954, the CHC adopted a 10.9 mi route for the Riverside-Ventura freeway extending from the junction with US 99, the Golden State Freeway, westerly to Sepulveda Blvd.
Construction of the freeway in the San Fernando Valley, between Hazeltine and Woodman, resulted in the displacement of the McKinley Home for Boys, which ran along (and consumed) the southern edge of the Home's property (the Northern edge was along Riverside Dr.). The Home relocated to San Dimas, CA.
Conejo Grade
The present-day path of the Conejo Grade between
Newbury Park and Camarillo was first laid out by William H. Brewer,
principal assistant to Josiah Whitney in the Geological Survey of
California. Brewer’s route was slightly north of present-day US 101.
It began at Moorpark and Olsen roads and then followed Santa Rosa Road
down the steep slope into Santa Rosa Valley in Ventura County. By the
mid-1870s, Brewer’s route was recognized for its directness.
Overland Mail stagecoaches used the road, which is labeled “Old
Butterfield Road” or “Butterfield Grade” on old-time
surveyors’ maps. Butterfield Road did save time in good weather. But
when the rains came, it was incredibly treacherous.
(Source: San Luis Obispo Tribune, 3/25/2017)
In 1935, an interesting rerouting of US 101 along the
Conejo Grade, traces of which are still visible today. The Conejo Grade
was originally routed in 1912 as one of the first roads to be surveyed by
the State Highway Department. By 1929, when the new Coast Highway (US 101A, signed Route 3, present-day Route 1) route was completed between
Oxnard and Santa Monica, the old route was overcrowded and some of the
sharper turns on the Conejo Grade had become quite dangerous. As a result
traffic showed a preference for the coast route so that about 60% of the
coast traffic followed the Oxnard-Santa Monica Route and only 40% chose
the old route. Truck traffic especially preferred the "sea level" route to
the steep grades, narrow roadbed, and inferior alignment on the Conejo
Grade. The old location, although in general fairly direct, necessarily
had many short radius curves in order to keep construction costs to a
minimum as well as keep within the allowable 6% maximum grade. Three
routes were considered:a North Route, a Middle Route and a South Route.
The "Middle Route" was by far the most direct alignment, but on account of
its directness it required a grade greater than 6% for a portion of the
distance. However, far better alignment could be obtained by adopting this
route, as well as keeping curvature to a much lower figure than on either
of the other routes. Surveys indicated that by using a 7% grade for the
two miles down the west slope of the Conejo Range, the Middle Route could
be used and thus secure the advantages of better alignment and shorter
distance. Note that the land for the Conejo Grade rerouting was donated by
Adolpho Camarillo, founder of Camarillo.
Note: See the Gribblenation Blog (Tom Fearer) "Former US Route 101 along Santa Barbara Channel (Gaviota Pass to Ventura)" for more detailed history on the development of US 101 in Ventura, including links to maps and CHPW articles.

Best attempts to note sources has been made; unsourced material is my research and observations.
By 1952, US 101/LRN 2 had moved to the Montalvo Freeway alignment from
the Santa Clara River northward into Ventura. The Montalvo Freeway
was the last limited access component necessary to connect Ventura-Oxnard
with a partially limited access grade.
(Source: Gribblenation Blog (Tom Fearer), “Former US Route 101 along Santa Barbara Channel (Gaviota Pass to Ventura)”, August 2021)
US 101 was originally aligned through downtown Ventura via Main Street. In 1923, it was realigned to diverge from Main Street via Garden Street and Meta Street (now Thompson Boulevard). In 1933, the new alignment of US 101/LRN 2 through Ventura onto Garden Street and Thompson Boulevard was also completed. The new alignment of US 101/LRN 2 connected back with Main Street east of downtown Ventura and followed it towards the Santa Clara River and Oxnard.
By 1955, US 101/LRN 2 from Central Avenue in Ventura the Santa Clara
River had been converted to freeway standards. The freeway segment
of US 101/LRN 2 terminated at the City of Ventura and emptied onto Main
Street just south of Telegraph Road/Thompson Boulevard. By 1957, a design
study was underway to extend the Ventura Freeway through the City of
Ventura where US 101/LRN 2 would be relocated. Freeway conversion through
Ventura was planned for FY60 anf FY61, and would include an interchange
with the already complete Ojai Freeway carrying US 399. This opened in
1962.

The bridge over the Ventura River originally dated back to 1912. In 1932,
the existing two lane Ventura River Bridge was slated to be replaced by a
four lane structure to facilitate more efficient travel on US 101/LRN 2. The new Ventura River Bridge would incorporate the piers of the
older structure. The new four lane Ventura River Bridge opened during late
1933. 1934 brought word of construction of a new overhead structure of the
Southern Pacific Railroad west of the Ventura River. The Ventura
Overhead structure was a realignment of existing US 101/LRN 2 from a
obsolete rail subway. The Ventura Overhead required a short
lengthening of the existing seawall and was completed during Fall
1934. In 1962, there was a planned extension of the Ventura Freeway
from the Ventura Overhead to the Santa Barbara County Line. The
planned extension of the Ventura Freeway would relocated US 101/LRN 2
uphill above the Rincon Seawall and Southern Pacific Railroad. The
relocation of US 101/LRN 2 above the Rincon Seawall would be done by the
mid 1960s (and result in the older route become a segment of Route 1 in
1980).

The Rincon Road Causeway between Ventura and Carpinteria was built by
1912 for a cost of $32,000. It was turned over to the California
Highway Commission for completion in 1912, and is 4.4 miles in
length. By 1914, contracts had been let for a segment of LRN 2 from
the Rincon Road Causeway to Sea Cliff. By 1915, they were working on the
Rincon Road Seawall, which would protect the highway and allow routing of
traffic away from Casitas Pass. By 1917, the new alignment along the coast
bypassing Casitas Pass was completed and in use. The Rincon Seawall was
reconstructed and expanded in 1924. In 1926, the Rincon Seawall opened as
a replacement of the Rincon Road Causeway between Sea Cliff and El Rancho
Rincon. The Rincon Road Causeway was removed during the construction
of the Rincon Seawall. The Rincon Seawall reclaimed a 6,400 foot
segment of land that was necessary to expand LRN 2.

The three mile segment of the Ventura Freeway from Palm Street to Emma Wood State Park began construction on February 28, 1961. This construction included a one mile segment of the Ojai Freeway (Route 33), which replaced a hazardous at-grade intersection that had originally existed. The project was completed in May 1963.
In 1929, US 101/LRN 2 between Carpinteria south over the Ventura County
Line to Benham was realigned. The Carpinteria-Benham realignment of
US 101/LRN 2 included an overhead crossing of the Southern Pacific
Railroad. The new overhead structure was a replacement for a
substandard rail subway and was to be complete by October 1929.

Santa Barbara / San Luis Obispo / Monterey / San Benito Counties
The route remained signed as US 101, and legislatively as LRN 2, into San Jose, running through Santa Barbara, San Luis Obsipo, Paso Robles, Salinas, and Gilroy.
In 1954, a three mile segment of US 101/LRN 2 from Punta Gorda (Mussel
Shores) to the Santa Barbara County Line was being converted to a four
lane expressway, and paving was in process on a new expressway bypass of
Carpinteria. TThe Carpinteria Expressway opened during December 1954, and
shifted US 101/LRN 2 north of downtown Carpinteria and the previous
alignment on Carpinteria Avenue.

In 1926, work was being done on a new alignment of LRN 2 through
Summerland and Ortega Hill. The new alignment of LRN 2 in Summerland
was to follow Lillie Avenue over a new 6.4% grade over Ortega Hill.
The existing Ortega Hill alignment in Summerland is shown to carry a grade
of 8.8%. Ortega Hill is stated to have been named after Spanish
Captain Jose Francisco Ortega. By 1927, reconstruction of US 101/LRN 2 between Summerland and Carpinteria was nearly complete.

In 1948, the Montecito Parkway four-lane expansion of US 101/LRN 2 took
place.expanding the segment from Sheffield Drive north to San Ysidro Road.
1948 also saw the start of the Salsipuedes Street Overhead in Santa
Barbara, which was the beginning phase of a realignment of US 101/LRN 2
off of Gutiterrez Street onto a expressway bypass. This was
completed in late 1948. In 1951, US 101/LRN 2 in Summerland was upgrade to
expressway standards, as an extension of the Montecito Parkway, extending
east to the Ventura County Line through a new grade in Carpinteria. By
late 1956, US 101/LRN 2 through Montecito had been converted to freeway
standards, US 101/LRN 2 through Goleta was in the process of full freeway
conversion, and US 101/LRN 2 from Ellwood to Orella was under an active
contract about to begin for a full freeway conversion.

US 101 in Santa Barbara
Note: See the Gribblenation Blog (Tom Fearer) "Former US Route 101 along Santa Barbara Channel (Gaviota Pass to Ventura)" for more detailed history on the segment between Ventura and Gaviota Pass.
Where noted, some of the material above and in this section is excerpted
and condensed from that blog. Other material in this section was some
shared research between Tom and I, and some was my own research. Such is
the honor among Roadgeek Thieves :-).
Prior to the state taking over maintenance of highways
in cities in 1933, LRN 2 was more of a named road, "Pacific Highway/El
Camino Real". A 1920 ACSC map shows the southbound as: State Street, De La
Vina Street, Micheltorena Street, State Street, Montecito Street, Milpas
Street, Cacique Street, Salinas Street and what is now Old Coast
Highway. The northbound is: Old Coast Highway, Salinas Street,
Cacique Street, Milpas Street, Haley Street, State Street, Mission Street,
De La Vina Street and State Street.
(Source: Gribblenation Blog (Tom Fearer), “Former US Route 101 along Santa Barbara Channel (Gaviota Pass to Ventura)”, August 2021)
In Santa Barbara prior to mid-to-late 1934, the
situation for US 101 appears muddled. The July 1934 CHPW indicated that US 101 entered from the SE along Old Coast Highway, up Salinas to Cacique,
over to Milpas, up to Gutierrez, over to De La Vina, which became
Hollister and exited to the W towards Goleta (although a 1945 map implied it might have been Punto Gordo instead of Cacique; however, the July 1934 CHPW says otherwise). As CHPW said of the early 1934 routing: “The motorist, when entering Santa Barbara from the south
along the present highway, is first confronted by a narrow underpass under
the Southern Pacific tracks, where the grade is steep and the alignment on
a 360-foot radius curve. A short distance farther on, the traveler again
crosses under the railroad, under almost equally dangerous conditions; and
thence proceeds along various city streets around no less than five
right-angle turns, and then follows northerly along de La Vina Street,
Hollister Avenue and out of the city on the north. De la Vina Street is
very narrow and its congested condition has always been an annoyance to
the traveler.”
(Source: GaryA on AARoads, "Re: US 101 on State Street in Santa Barbara", 4/26/2021; DPF research based on that post; July 1934 California Highways and Public Works)
However, earlier ACSC maps from around 1920 had some
slight differences. They show a couplet using Haley and Montecito instead
of Gutierrez, and use of State Street instead of De La Vina between that
couplet and Micheltorena. Between Micheltorena and Mission, State Street
and De La Vina are a couplet, and then the routing continues to the N
along De La Vina.
(Source: DTComposer on AARoads, “Re: US 101 on State Street in Santa Barbara”, 5/28/2021)
In November 1934, the routing changed with a new
trafficway. The section along "Old Coast Highway", Salinas, and Cacique
was bypassed with the adoption of a route closely paralleling the Southern
Pacific railroad. This involved a total construction of 5.9 miles of
highway, together with two steel and timber bridges over Mission Creek, a
reinforced concrete overhead structure over the previous highway, and a
similar type structure to carry a county highway over the new road. The
new alignment has a graded roadbed width of 46 and 56 feet along the new
alignment, and 76 feet in width where contiguous with existing city
streets with surfacing 30 feet wide throughout, and all structures are
being built to accommodate future widening. CHPW noted that “At the
northerly end of the city, where the new road parallels the railroad, it
has been necessary to construct a reinforced concrete girder type overhead
structure to carry a well traveled county road, this structure directly
connecting to an existing timer bridge over the Southern Pacific railrood.
At the northerly end of the work, where a connection is made again with
the present State highway on Hollister Avenue, additional right of way
hall been acquired to permit the future construction of a braided traffic
intersection to effectively handle the ever increasing volume of traffic
in this vicinity.”
(Source: July 1934 California Highways and Public Works. H/T to DTComposer for finding the article)
The resulting new route is shown in the 1934 State Highway map: US 101 entering from the south along the new
alignment S of "Old Coast Highway" to Milpas, NW on Milpas, turn L (SW) on
Gutierrez, curve R (NW) on Rancheria, merge (NW) onto a new alignment via
Greenwell and Modoc, and then onto Hollister (near the current Route 154
junction). By 1945, one map shows Rancheria continuing to San Marcos Pass Road, with US 101 running along Rancheria to San Marcos Pass to Hollister
(although the 1948 State Highway map seems to dispute that). At this time,
LRN 150 (Route 225) ran along Cabrillo Blvd from US 101 on the E end to
Castillo, along Cliff Dr, to Las Posistas, back to join US 101 at Modoc.
Also, by 1948, the expressway was under construction from Milpas to Rancheria. By 1960, Rancheria had been renamed
Hollister.

In 1947, US 101/LRN 2 was upgraded from the City Limit
of Santa Barbara 9.3 miles northward to Tecolote Canyon. This new
alignment of US 101/LRN 2 replaced Hollister Avenue through Goleta between
the Hollister Underpass and the newly constructed Ellwood
Overhead. The relocation of US 101/LRN 2 through Goleta was
spurred by interests from the U.S. Marine Corps Station during World War
II. The realignment of US 101/LRN 2 from Santa Barbara to Tecolote
Creek was constructed during three projects, the last concluding during
March 1947.

In 1954, plans were started for the removal of the
traffic lights in Santa Barbara. There were four traffic lights . The
state wanted them removed. The city wanted them removed. So the state
conducted a preliminary study. But the city rejected the state's design
for an elevated freeway through Santa Barbara. Then the state rejected the
city's design for a depressed freeway. And for the next three decades more
than a hundred designs were proposed and rejected, more than $3 million
was spent by Caltrans on studies, dozens of environmental impact reports
were written and 18 separate city councils debated the issue. Through it
all the traffic lights remained a frequent source of Angst for weekend
travelers, a daily irritant for residents and a symbol of bureaucratic
delay. It wasn't until 1988 that the project to remove them began. City
officials traditionally have worked hard preserving Santa Barbara's
Spanish architectural heritage, limiting growth, maintaining the
Mediterranean calm of the city. They are accustomed to stalling proposals
until their specifications are met. But the freeway project -- completed
in 1991, almost 40 years after it was first discussed -- is a long time to
marshal a project to completion. The city, however, will finally get the
freeway it wants. And it's not just another anonymous swath of concrete
cutting through town. The city contributed $250,000 for arches, ironwork
and other flourishes so one of the freeway under-crossings will look like
a Spanish Renaissance bridge and be a gateway to the city. Although for
decades neither the city nor the state could agree on a plan, both shared
an overriding goal--the elimination of the traffic lights. The state
wanted the lights removed because they represented the only interruption
along the 435 miles of US 101 between Los Angeles and San Francisco. The
city wanted the lights removed because the exhaust fumes from idling cars
cause pollution and the accident rate--about 200 a year--is much higher
than the average four-lane urban freeway. Also, cross-traffic backs up for
blocks as residents wait for the light to briefly flash green. The average
wait is four minutes, according to Caltrans, and up to eight minutes on
busy weekends. That makes it the longest traffic signal in the state. For
every Caltrans proposal, the city has offered a counterproposal. Soon
after Santa Barbara rejected the elevated freeway, city officials
suggested a depressed freeway, with the roadbed below street surface and
cross-streets going over the highway. The state was not receptive because
of the greater expense and technical difficulties. So city officials
devised a number of other variations on the proposal, none of which were
accepted. Throughout much of the 1950s and 1960s, the city and state were
at odds. Neither side could agree on a plan. Out of desperation Caltrans
even briefly studied a proposal to avoid the city entirely by rerouting US 101 through the mountains to the northeast. Eventually, Caltrans took a
more conciliatory approach and Santa Barbara became more amenable to
compromise. By 1971, the City Council and the state agreed on a
ground-level freeway proposal with under-crossings for three main downtown
streets. But the next year a new City Council was elected and it had
reservations about the project. The council studied a depressed freeway
again, but eventually returned to the plan that had been approved. So for
the next three years they examined variations of this proposal until, in
the mid-1970s, a compromise was reached. The plan was finally accepted by
both the city and the state. The city's aesthetic and environmental
concerns were satisfied. The state's budgetary limits were not exceeded.
But then the money wasn't there. Funding for new freeway projects dried up
during the mid-1970s to the early 1980s, Nicholson said. Highway funds
didn't keep pace with inflation and the Administration of Gov. Edmund G.
Brown Jr. was reluctant to allocate funds for road construction. When
Brown left office in 1983, planning for the freeway commenced at last. And
during the last few years the city and state held meetings, refined the
design and planned for construction. Instead of traffic lights and the
four-lane highway, an expanded six-lane freeway will be built.
Under-crossings for both pedestrians and cars will be constructed at
Garden and State streets to connect the waterfront with downtown.

In 1918 the Arroyo Hondo Bridge was completed over the namesake creek
between Gaviota siding and Ellwood siding. The 1918 Arroyo Hondo
Bridge is a 536 foot long open spandrel arch concrete bridge which was
among the earliest of such design built as part of a State Highway. In
1941, US 101/LRN 2 was expanded to four lanes between Las Varas Creek 3.4
miles to Tecolote Creek and Orella siding 1 mile west of Canada del
Refugio. There was also a secondary project to construct a new
bridge over Dos Pueblos Creek which was completed by March 1941. In 1950,
US 101/LRN 2 was expanded to a freeway between Arroyo Hondo and Arroyo
Quemando. The expansion of US 101/LRN 2 between Arroyo Hondo-Arroyo
Quemando led to both existing bridges being converted to southbound
usage.

Goleta and the Gaviota Pass
Note: There is good information on the history of the Gaviota Pass (approx SB 47.277) on the Goleta History Website and the Gribblenation Blog “US Route 101 through Gaviota Pass” (Tom Fearer). The following information is summarized from those sources; consult the sources for more detailed information.
The Gaviota Pass is the only real gap in the Santa Ynez
mountain range for miles (the other passes in the area are San Marcos, Route 154, and Refugio,
which is Refugio Road and Forest Road 5N12 between US 101 and Route 246).
The steep and rugged mountains rise about 2,000 feet on each side. The
pass started as a Chumash trail that took them over the crest of the
coastal range for visits to the back country. It was widened for the
Europeans, but the rocky pass was often blocked by boulders that fell off
the cliffs, flooded out, or obstructed by mud and debris. In 1846 during
the Mexican-American War the path through Gaviota Pass played a
significant part as was to be an ambush point to trap the forces of U.S.
Army Lt. Colonel John C. Fremont. Fremont's troops instead diverted
east from Gavoita Pass over the Santa Ynez Mountains and discovered what
is now San Marcos Pass. In 1854, chisels were taken to the rock walls of
Gaviota Pass to widen the trail enough for wagons to fit through. Passage
was still treacherous, and the flow of the creek could still make it
impossible. Traffic continued to increase in the 1860’s as more
ranches developed in the Valley. The earliest travelers made note of the
large overhanging rock on the west side of the pass that resembled an
Indian head, watching over the pass. It’s still there today, hanging
over the southbound lanes. In 1861, dynamite was used to widen the pass
and the first county road was finished with a wooden bridge over the
Gaviota Creek.
(Source: Goleta History, 9/15/2015; Gribblenation Blog “US Route 101 through Gaviota Pass”, June 2021)
Gavoita Pass was signed as part of the American El
Camino Real auto trail starting in 1906. State Maintenance started
with the 1909 bond act; one of the highways approved was a 481.8 mile
highway originating at the City Limits of San Francisco which terminated
in San Diego (LRN 2). Additionally, in 1913 the Pacific Highway was
plotted as a major Auto Trail which had Gaviota Pass along it's planned
route. Also in 1913 the Division of Highways starting planning the
specific route for LRN 2 between Santa Maria and Gaviota Pass. The
route through Zaca Canyon towards Gaviota Pass was chosen over the
alternatives due to it being the most direct line southward from Harris.
In 1915 the State Division of Highways took control of the road,
graveling, straightening and widening it, as well as completing the road
from Harris S to Gaviota Pass. By 1924, LRN 2 had been widened through
Gaviota Pass and by 1926, it became US 101. The wooden bridge over Gaviota
Creek was replaced by a steel suspension bridge in 1927.
(Source: Goleta History, 9/15/2015; Gribblenation Blog “US Route 101 through Gaviota Pass”, June 2021)
In 1931 the road was again widened, straightened, paved
and a new concrete bridge replaced the steel bridge. The road surface
through Gaviota Pass was widened from 21 feet to 36 feet. This alignment
serves as the southbound lane of US 101, and the 1931 Gaviota Creek Bridge
is still present. After World War II attention was turned to improving the
two-lane Coast Highway as this was the only pass on the coast from south
to north and faster moving cars demanded more room on the road.Rather than
further widening the pass by removing massive amounts of rock from the
mountainside, a tunnel was “holed through” on the east side of
the gap, starting in 1952. The tunnel could only be bored out from the
south side because there was no safe way to remove the dirt and rock from
the north end. The lights in the tunnel were the first power lines in
Gaviota Valley. The tunnel is 435 feet long, 35 feet wide and 18 feet
high. The walls contain 18 inches of cement. The Gaviota tunnel was
completed in May 1953. Heavy duty nets designed to catch falling boulders
were placed above the highway in 1992.

During 1933, LRN 56 was extended to a new south
terminus at US 101/LRN 2 at Las Cruces immediately north of Gaviota Pass.
This was signed as Route 1 in 1934.
(Source: Gribblenation Blog “US Route 101 through Gaviota Pass”, June 2021)
In the mid 1930s, there were numerous realignments to
straighten the roadway. In 1934, a realignment between Gaviota and Arroyo
Hondo functioned as an extension of the work completed on US 101/LRN 2 in
Gaviota Pass, eliminating 31 curves along with 0.127 miles of travel
between Gaviota and Arroyo Hondo. In 1935, a realignment from Gavoita Pass
to Nojoqui Creek eliminated 33 curves and 0.877 miles of travel.
(Source: Gribblenation Blog “US Route 101 through Gaviota Pass”, June 2021)
In 1947, it was reported that the original coast highway was relocated for 9.3 mi N of Santa Barbara to Tecolote Canyon. The revised routing replaced the old route through the town of Goleta between the Hollister Underpass and the Elwood Overhead. The old highway became a county road. The new highway is a four-lane divided roadway. The alignment parallels the SP main line for approximately eight miles, and replaced an old road that had 17 curves and grades of up to 6%.
In 1951, there was an expansion of US 101/LRN 2 in
Gaviota Pass to a four lane highway for slightly over 5 miles originating
near Gaviota northward towards Nojoqui Creek. The key piece of the
expansion of US 101/LRN 2 in Gaviota Pass was a tunnel. Construction of
the Gaviota Tunnel portals was completed on May 13th, 1953. The
Gaviota Tunnel was 435 feet in length. IN 1956, the Nojoqui Expressway
segment opened north of Gavoita Pass. The Nojoqui Expressway was a
four lane divided highway originating 1 mile north of Nojoqui Summit
northward 11 miles to a half mile from the Santa Ynez River, and connected
to the four lane alignment of US 101/LRN 2 completed over Nojoqui Summit
during 1951.
(Source: Gribblenation Blog “US Route 101 through Gaviota Pass”, June 2021)
In the Santa Ynez Valley, the route that became LRN 2 did not follow the
routing of the previous Spanish El Camino Real and its 1906 American Auto
Trail successor. There were numerous suggested alignments of LRN 2 as it
was plotted in 1913. Several of the suggested routes diverge west from
Gaviota Pass towards Lompoc and Mission La Purshima. An easterly
suggested route was aligned past Mission Santa Inés near
Solvang. Ultimately a more central route through Santa Ynez Valley
through Buell Ranch onward towards Zaca Canyon was selected as the
alignment of LRN 2. In 1913 the Pacific Highway was plotted as a
major Auto Trail which followed LRN 2 through Santa Ynez Valley. By 1926,
the route was aligned through Buellton; by 1935, US 101/LRN 2 was aligned
on Avenue of the Flags. By 1948, there was a rebuild and expansion of US 101/LRN 2 in Buellton, including an expansion of US 101/LRN 2 on Avenue of
the Flags to expressway standards along with two new steel bridges at
Nojoqui Creek and the Santa Ynez River. The freeway bypass was
budgeted for FY63-64, and completed in June 1965.

US 101 in Nipomo (~ SLO 1.211 to SLO 8.269)
Note: See the Gribblenation Blog "Former US Route 101 through Nipomo" for more details, including source documents and maps, regarding this segment.
Tom Fearer notes that within the community of Nipomo
the original alignment of US 101 can be found on Thompson Avenue. The
first specific evidence of this on a state highway map is the 1935 map,
and it remained along Thompson Avenue until the mid 1950s. In 1956, a
realignment, including several freeway structures, was announced that
would originate 3 miles north of Santa Maria at Hourihan Grade and ended
approximately another 7.1 miles to the north at Russell Turn. This was
completed in 1957.

US 101 in Arroyo Grande and Pismo Beach (~ SLO 12.497 to SLO 17.098)
Note: See the Gribblenation Blog "Former US Route 101 through Pismo Beach and Arroyo Grande" for more details, including source documents and maps, regarding this segment.
Tom Fearer notes that the City of Arroyo Grande has two
historic alignments of US 101: one that follows Branch Street and Bridge
Street over the 1908 Arroyo Grande Creek Bridge and the other that follows
Traffic Way. Within the City of Pismo Beach the original alignment of US 101 is along Price Street. Historically, initial improvement of the
highways in this area, along LRN 2 between Arroyo Grande to Pismo Beach,
occurred during 1914 when the route was in 15 foot wide concrete
slabs. In 1925, it was noted that there was a cooperative plan
between the California Highway and Railway Commissions to eliminate an
at-grade crossing of the Southern Pacific Railroad on LRN 2 in Pismo
Beach, which was the only remaining unpaved segment of LRN 2 between San
Francisco and Los Angeles. This resulted in a new bridging structure
(opened in 1926) crossing Villa Creek towards Hinds Avenue, replacing an
alignment across via the now closed Bello Street Bridge. The roadway was
reconstructed to 20-30' concrete slabs in 1929. A project in 1931 in
Arroyo Grande towards Berros Creek realigned US 101/LRN 2 off of Branch
Street and Bridge Street in downtown Arroyo Grande to a new alignment and
a new bridge over Arroyo Grande Creek via what is now Traffic Way. This
realignment eliminated 32 curves between Arroyo Grande and Los Berros
Creek; after the realignment, former US 101 on Branch Street east of
Traffic Way to Bridge Street was incorporated into LRN 147 (future Route 227).
(Source: Gribblenation Blog (Tom Fearer), "Former US Route 101 through Pismo Beach and Arroyo Grande", July 2021)
In 1949, a four lane segment of US 101/CA 1/LRN 2 from
Pismo Beach north to Miles Station opened. This upgrade from one
mile north of downtown Pismo Beach incorporated the existing highway into
the
southbound lanes towards the Shell Beach area. Through Shell Beach,
US 101/LRN 2 was moved to a bypass of Price Street/Shell Beach Road.
(Source: Gribblenation Blog (Tom Fearer), "Former US Route 101 through Pismo Beach and Arroyo Grande", July 2021)
In 1951, the CHC adopted a new routing for US 101 in the Five Cities area,
from 0.5 mi S of Arroyo Grande to Pismo Beach, a distance of 5½ mi.
They also declared the route to be a freeway. The non-freeway routing had
deficient traffic capacity, with high accident potential for the movements
in Arroyo Grande. The rural portion S of Arroyo Grande, and between Arroyo
Grande and Pismo Beach, had a number of sections with inadequate passing
sight distance and a high accident rate. The estimated cost at the time
was $2.7mil, including right of way. Start of construction was dependent
on availability of funds. It was planned as a four-lane divided highway,
with provisions for ultimate expansion to a six lane divided facility.

The freeway conversion between Arroyo Grande and Pismo
Beach was budgeted in 1953, and completed in September 1956. The Arroyo
Grande freeway alignment was completed in 1959; the Pismo Beach freeway
alignment was completed in 1961. Price Street in downtown Pismo Beach is
noted to have been the last surface street alignment of US 101/LRN 2 to
have been bypassed in San Luis Obispo County. The conversion of the
expressway to freeway near Shell Beach was completed in 1965.

US 101 in San Luis Obispo (~ SLO R24.849 to SLO 30.506)
An interesting side note about San Luis Obispo: It was the location of the first motel. To be more specific, in December 1925, architect Arthur S. Heineman opened a group of cottages that permitted lodgers to drive to their doors. It was originally named the Milestone Motel, but was later called the "Mo-Tel Inn." It was located at 2223 Monterey Street, and accomodated 160 guests. It is next to the current Apple Farm restaurant and motel. For more information, visit the History in San Luis Obispo County site.
In San Luis Obispo, the south section of US 101 began
at the convergence of the current US 101 freeway and South Higuera Dr. In
the southern portion of this section, US 101 exists in three flavors: (1)
the current freeway, (2) South Higuera Drive, and (3) the oldest section,
which extends from near S. Higuera and the freeway north to about a
quarter mile south of the intersection of S. Higuera and Los Osos Valley
Rd., then continuing north on S. Higuera and stops at South Street. The
northern section began at South Street, and continues north on S. Higuera
up until the intersection with Marsh Street. The original LRN 2, which was
designated US 101 in 1925, came north on Higuera up to Chorro St., then
jogged over one block to Monterey St, and contuinued north out of town.
Beginning in 1933, old US 101 was re-routed up Marsh Street, all the way
to Santa Rosa where it turned east for two blocks over to Monterey Road,
thence turning north on Monterey Road and continuing up to the merge with
the current freeway. The 1953 freeway bypass cut off a small section of
the old route in the area of Cuesta Park. From there it follows the
existing freeway route north to the Cuesta Grade section.
(Source: Historic 101, which provides detailed maps and photos)
Tom Fearer notes that originally US 101, upon
descending Cuesta Pass southbound, entered the City of San Luis Obispo via
Monterey Street. From Monterey Street, US 101 utilized Santa Rosa
Street and Higuera Street southbound through downtown San Luis
Obispo. Upon departing downtown San Luis Obispo, US 101 would have
stayed on Higuera Street southward towards Pismo Beach and Arroyo
Grande. Beginning in 1934, US 101 picked up Route 1 at the
intersection of Monterey Street/Santa Rosa Street where the two would
multiplex to Pismo Beach. Circa 1923, LRN 2 (future US 101) used Monterey
Street, Chorro Street and Higuera Street headed southbound through SLO,
with major highways departing LRN 2 at Broad Street southward and Santa
Rosa Street northward. It is unclear when through route of LRN 2
shifted from Chorro Street to Santa Rosa Street. However, by 1931, LRN 56
(Route 1) was using Santa Rosa St to enter SLO meeting US 101 at Monterey
St and continuing along Higuera towards Pismo Beach; by 1933, LRN 147
(future Route 227) was using Broad Street and terminating at US 101 at
Higuera.

In 1948, a new four lane alignment of US 101/Route 1/LRN 2 from Miles Station 6.6 miles north to Marsh Street in San Luis
Obispo opened. This new segment realigned both highways northbound
onto an alignment that entered downtown San Luis Obispo via Marsh
Street. Northbound US 101/Route 1/LRN 2 multiplexed on Marsh Street
onto Santa Rosa Street towards the split at Monterey Street. At
Monterey Street, US 101/LRN 2 departed towards Cuesta Pass whereas Route 1/LRN 56 stayed on Santa Rosa Street towards Morro Bay. This shift
saw LRN 147 (Route 227) truncated to a new terminus at the intersection of
Broad Street and Marsh Street. The freeway bypass realignment
occured in 1952-1953, from Marsh Street 2.3 miles to San Luis Obispo
Creek. This alignment removed US 101/Route 1/LRN 2 off the surface streets
of downtown San Luis Obispo onto a new limited access grade that entered
San Luis Obispo on a multiplex to the Santa Rosa Street exit, where Route 1 would split towards Morro Bay via LRN 56. Northbound US 101
continued on LRN 2 towards an existing expressway segment in Cuesta
Pass. LRN 147 was extended via a one-couplet on Higuera Street and
Marsh Street to a new terminus at US 101/Route 1/LRN 2.

At the end of December 1962, the SLO Telegram-Tribune
noted the following about highway construction in the SLO area:
(Source: SLO Tribune, 12/28/2018)
US 101 in Santa Margarita (~ SLO 37.472) and Atascadero (~ SLO 41.821 to SLO 49.264)
Note: See the Gribblenation Blog "Former US Route 101 through Atascadero and Santa Margarita" for more details, including source documents and maps, regarding this segment.
The original routing of US 101 generally followed the
road named “El Camino Real” through both Santa Magarita and
Atascadero. Based on analysis of maps by Tom Fearer as noted in the blog
citation, it appears this route dates back to the original signage of the
El Camino Real auto trail in 1906, and continuing through its
establishment as LRN 2 and later as US 101. In 1929, there were numerous
upgrades to El Camino Real: expansion of the road surface to 20' concrete
from the Southern Pacific Railroad siding of Cuesta 1.9 miles north to the
outskirts Santa Margarita, construction of a 38' wide timber bridge
immediately north of Santa Margarita eliminating a dangerous curve, and
another 20' concrete section from north of Atascadero 9.6 miles north to
Paso Robles. A similar upgrade was made between San Margarita and
Atascadero in 1932. In 1952, this was converted to 4 lanes between
Atascadero and Templeton. In 1955, construction of the bypass alignment
around Santa Margarita and Atascadero was started; it was completed in
1957, tying into the existing expressway on both ends (and bypassing the
surface routing of "El Camino Real").
(Source: Gribblenation Blog (Tom Fearer), “Former US Route 101 through Atascadero and Santa Margarita”, July 2021)
US 466 was announced in 1933, with an implication that
it would run along LRN 33 (1934-1964 Route 41, current Route 46) to US 101, and then down US 101 to 1934-1964 Route 46 (current Route 41) in
Atascadero. However, that was omitted by the Division of Highways
response, who instead kept US 466 on not only the Morro Bay to Atascadero
section of LRN 125 (then Route 46/now Route 41), but an unsigned routing
of LRN 125 from Atascadero to Creston and Shandon and LRN 33. It wasn't
until 1957 that US 466 was officially aligned along US 101 to Paso
Robles/Templeton and the LRN 33 (then Route 41/now Route 46) routing. When
the bypass of Santa Margarita and Atascadero was completed, US 466
remained on El Camino Real. Initially, westbound US 466/LRN 125 entered
downtown Atascadero on West Mall and jogged south on El Camino Real to
Morro Road. The bypass of Santa Margarita saw LRN 58 (1934-1964
Route 178/current Route 58) extended through Santa Margarita on El Camino
Real to the new alignment of US 101/LRN 2. US 466 was truncated to Baker
in 1964, the same year that saw the Route 41/Route 46 numbering switch W
of Shandon, and the change from Route 178 to Route 58.
(Source: Gribblenation Blog (Tom Fearer), “Former US Route 101 through Atascadero and Santa Margarita”, July 2021)
With the elimination of US 466, post-1964 Route 41 was
signed on former US 101 in downtown Atascadero on El Camino Real between
West Mall and Morro Road. The Salinas River Bridge carrying Route 41 on
Acacia Road was destroyed in March 1995 due to flooding; this led to Route 41 being realigned over the Salinas River Viaduct by 2003.

US 101 in Templeton (~ SLO 51.105)
Note: See the Gribblenation Blog "Former US Route 101 through Templeton" for more details, including source documents and maps, regarding this segment.
In Templeton (~ SLO 51.105), Main Street and possibly Old County Road is a former routing of US 101.
LRN 2 was legislatively authorized in the 1909 bond
act, and would become US 101 in 1926. Early LRN 2/American El Camino
Real/Pacific Highway passed through Templeton on Main Street as of 1917.
By 1951, US 101/LRN 2 had been converted to four lanes between Atascadero
and Templeton. This four lane segment is noted to be a component of
a larger divided highway project planned to extend through Templeton to
Paso Robles. US 101/LRN 2 had been expanded to four lanes
immediately south of Paso Robles through Templeton by summer 1953.
The "Templeton Bypass" realigned US 101/LRN 2 onto a new expressway grade
that replaced Main Street. This resulted in a significant decline in
overall sales throughout Templeton after the opening of the Templeton
Bypass. The Templeton Bypass connected to the previously
completed four lane expressway segment south of the community in 1951.
(Source: Gribblenation Blog “Former US Route 101 through Templeton” (Tom Fearer), June 2021)
In 1958, US 466 was routed off of LRN 125 between
Atascadero and Shandon (a routing that was never signed) onto LRN 33 out
of Templeton (future Route 46, 1934-1964 Route 41). In 1963, US 101/US 466
was converted to freeway. Interchange structures on modern US 101 show the
Main Street Interchange was completed in 1966 and the Las Tables Road
Interchange in 1967. Following the completion of the Las
Tables Road Interchange US 101 was converted to full freeway standards in
Templeton.

History of US 101 in Paso Robles (~ SLO 58.696)
Note: Much of the information in this subsection is summarized from the Gibblenation Blog “Former US Route 101 and California State Route 41 through Paso Robles” (Tom Fearer). See the blog for additional details.
As originally configured the surface alignments of US 101 and Route 41 (renumbered in 1964 as Route 46) converged in downtown
Paso Robles. US 101 originally was aligned through Paso Robles via
Spring Street. 1934-1964 Route 41 entered the City of Paso Robles
via Union Road and 13th Street where it intersected US 101 at Spring
Street. US 101 and 1934-1964 Route 41 (Route 46) departed Paso
Robles southbound via a multiplex which split near Templeton.
(Source: Gribblenation Blog “Former US Route 101 and California State Route 41 through Paso Robles” (Tom Fearer), June 2021)
As noted earlier, a north/south state highway through
Paso Robles was first authorized in the 1909 bond act and became LRN 2;
this became US 101 in 1926. The future Route 41 (LRN 33) was added in the
1916 bond act. During 1933, LRN 33 was extended to a new terminus west of
Paso Robles at LRN 56 (Route 1) in Cambria. LRN 33 became Route 41
in the 1934 state route signage. In Paso Robles, the new Route 41
multiplexed US 101 on Spring Street in downtown Paso Robles from 13th
Street southward. Between 1952 and 1953, the section of US 101 was
widened to four lanes. It opened as freeway from Paso Robles to San Miguel
in 1955. In 1957, work was progressing on a realignment of US 101/LRN 2 on
the Paso Robles Bypass, which was 5.1 miles in length and would tie into
the existing divided highway segments on both ends of the City. The
Paso Robles Bypass Project included a tie-in with the the recently
completed realignment of 1934-1964 Route 41/LRN 33 from Huerhuero Creek
east to the Estrella River. It opened in 1958.
(Source: Gribblenation Blog “Former US Route 101 and California State Route 41 through Paso Robles” (Tom Fearer), June 2021)
In 1952, the CHC announced the adoption of a freeway
routing for the 6 mi segment of US 101 between Paso Robles and San Miguel.
This segment carries a heavy volume of Camp Roberts traffic. The plan is
for a four-lane divided highway, either using a new routing just W of the
existing routing, or on the existing routing using the existing roadbed as
the NB lanes. This segment connects with previously adopted routings in
Paso Robles and the town of San Miguel. It starts at 36th
street in Paso Robles, makes a wide swing to the W of the existing
highway, although with far fewer and gentler curves, as far as San Marcos
Creek. From San Marcos Creek to approx. 0.5 mi S of San Miguel, the new
route is adjacent to the existing highway.
(Source: The Tribune, 6/12/1952, via Joel Windmiller, 2/23/2023)
In June 1958, US 466 was routed off of LRN 125 between
Atascadero and Shandon. LRN 125 between Atascadero-Shandon was
substandard in design, and despite being part of US 466 since 1933 was
never signed as such. The new alignment of US 466 would see it briefly
multiplex 1934-1964 Route 41/LRN 33 west of Shandon to Paso Robles via 24th
Street and US 101/LRN 2 south to Atascadero via Spring Street. US 466 was
truncated to end in Baker in 1964.

San Miguel (~ SLO 66.01)
In the Gribblenation Blog “Former US Route 101 in San Miguel”, Tom Fearer explores the history of the community of San Miguel, and the original routing of US 101
in the area. The main state highway in the area, LRN 2, was established in
1909, with a routing along Mission Street. The routing is shown on the
1917 CSAA map of the area. After the US highway system was established in
1926, this segment became part of US 101. The route remained unchanged
until the late 1950s, when the San Miguel Bypass was constructed as a 3.1
mile long realignment of US 101 south of San Miguel north to the southern
boundary of Camp Roberts. It opened to traffic as the new alignment
of US 101 in late November 1957.

Bradley (~ MON R6.704)
In the Gribblenation Blog “Former US Route 101 in Bradley”, Tom Fearer explores the history of the community of Bradley, and the original routing of US 101 in
the area. The main state highway in the area, LRN 2, was established in
1909, with a routing along Bradley Road. Early maps from 1913 and 1917
show this routing; it became part of US 101 with the designation of the US highway system in 1926. Heading southbound US 101 originally crossed the
Salinas River to Dixie Street. From Dixie Street US 101 swung via a
couple of 90° turns via Pleyto Street to Meadow Avenue. By
1929, a new alignment and bridge over the Salinas River was being
considered. The original Bradley Bridge was constructed in 1888 by
Monterey County. The new Bradley Bridge was completed in 1930.
(Source: Gribblenation Blog (Tom Fearer), “Former US Route 101 in Bradley”, January 2021; Image source: May/June 1965 CHPW)
By 1965, plans were underway to convert US 101 in the
area to a freeway. In August 1965, US 101 from San Miguel to Camp Roberts
had been realigned to a freeway. Completion of the new bypass of
Bradley was anticipated to be complete by summer of 1966.

San Ardo (~ MON R21.904) to San Lucas (~ MON R32.851)
In the Gribblenation Blog “Former US Route 101 from San Lucas to San Ardo”, Tom Fearer explores the history of the communities of San Ardo and San Lucas, and the
original routings of US 101 in the area. The main state highway in the
area, LRN 2, was established in 1909. Early LRN 2, which was part of the
signed auto trail the American El Camino Real, ran along what is
now Cattleman Road from the outskirts of King City southward to San Ardo,
as shown on the 1917 CSAA map. There was a planned rerouting east of the
Southern Pacific Railroad that never was constructed. The route was also
part of the 1913 Pacific Highway. In 1926, US 101 was
designated. At that time, US 101/LRN 2 headed southbound passed through
San Ardo via Railroad Street and Jolon Street. It then followed Jolon
Street via a bridge over the Salinas River. The route was realigned in
1929 when the Cattleman Road Bridge was constructed, replacing the 15'
wide original bridge constructed in 1907.
(Partial source: Gribblenation Blog (Tom Fearer),
“Former US Route 101 from San Lucas to San Ardo”, January 2021; this page previously noted that Cattleman Road was former US 101)
By the mid-1960s, planning had started for the conversion
of US 101 to a freeway in the area, from San Ardo south to Bradley.
The San Lucas-San Ardo segment of US 101 was stated to be in the design
phase for a freeway upgrade. This upgrade first showed on a map in 1966
(as planned); the upgrade was completed during the early 1970s and first
on the 1975 Caltrans State Map.

Over on AARoads, Scott Parker noted the following
regarding San Ardo: The main reason for the US 101 relocation west of the
Salinas River from San Ardo to San Lucas was the presence of a large
oilfield along US 101 in that area; back when the revised route was
adopted in the early '60's the concept of disturbing an oilfield was
unheard of in CA state government circles. That oilfield remained in
full operation into the '90's.
(Source: Scott Parker (SParker) on AARoads, "Re: Old US Route 101 King City", 4/19/2020)
San Lucas (~ MON R32.851)
The original alignment of US 101 was carried on LRN 2
(created in 1909). Surveyed in 1910, by 1917 the route was routed on Main
Street in San Lucas. Future Route 198 originally followed Mary Street via
LRN 10 (extended to San Lucas in 1915) into San Lucas and Main Street. By
1925, LRN 2 had been rerouted and shifted west of the Southern Pacific
Railroad in San Lucas onto what is now Cattlemen Road. This led to
LRN 10 being extended through San Lucas via Main Street to a new terminus
at Lockwood-San Lucas Road and Cattleman Road. This aligned LRN 10
directly with the 1915 Salinas River Bridge located on Lockwood-San Lucas
Road. In 1926, LRN 2 was signed as US 101; in 1934, LRN 10 was signed as
Route 198.
(Source: Gribblenation Blog (Tom Fearer), "Former US Route 101 and California State Route 198 in San Lucas", November 2022)
Beginning in 1965, work began to realign US 101 to a
freeway grade between San Ardo north to King City. This also included a
1.1-mile realignment of Route 198 to the US 101 freeway in San Lucas.
Right of way acquisition for both US 101 and Route 198 realignments began
at that time. is stated to be planned to commence during 1965. In 1972, US 101 was shifted to a new freeway west of Cattlemen Road and Route 198 was
extended directly to it via an interchange structure south of San
Lucas. Former Route 198 in San Lucas was partially severed after the
highway was realigned, as Mary Street no longer directly connects traffic
from Route 198 to Main Street. The Southern Pacific Railroad
crossing from Main Street to Cattlemen Road/Lockwood-San Lucas Road was
removed.

King City (~ MON R41.71R)
In the Gibblenation blog "Old US Route 101 in King City and the 1903 Southern Pacific Railroad Depot", Tom Fearer explores the history of King City, and the original routing of US 101 in that community. As noted above, the main
state highway in the area, LRN 2, was established in 1909. The original
planned alignment of LRN 2 required crossing the Salinas River at King
City. The plan was to use the existing wooden highway bridge over the
Salinas River in King City, but this was destroyed in a flood and was
replaced in 1919. Until the 1919 Salinas River Bridge was completed
traffic headed south from Salinas to King City would have had to use Metz
Road. King City was one of the last parts of LRN 2 to be paved when
the San Lorenzo Creek Bridge, on 1st Street in King City opened
to traffic around 1924. By 1926, this was part of US 101; northbound the
original alignment through King City was on 1st Street,
Broadway Street, and the 1914 Salinas River Bridge.
(Source: Gribblenation Blog (Tom Fearer), “Old US Route 101 in King City and the 1903 Southern Pacific Railroad Depot”, February 2020)
In 1956, the new Salinas River Bridge in King City
opened. It was intended to carry the NB lanes of US 101, with the 1919
bridge carrying SB traffic. The 1956 Salinas River Bridge originated at
Canal Street and spanned 1.8 miles northbound across the Salinas
River. US 101 at the time was planned as an expressway, but was
still using Broadway Street and 1st Street in King City. In the
1961-1962 timeframe, planning was underway for a new 19.7 mile freeway
alignment of US 101 within Monterey County. The final freeway route
adoption of US 101 was selected in June 1962. Construction was planned for
the 1967-68 fiscal year, and included replacement of the 1919 Salinas
River Bridge to make the new alignment fully conform to freeway standards.
Upon the completion of the King City bypass route, the former
surface route in downtown King City was added to County Sign Route G13 and County Sign Route G15.
1st Street became an extension of County Sign Route G15 whereas County Sign Route G13 was
extended over Broadway Street.

Greenfield (~ MON 53.37)
The original alignment of US 101 in Greenfield was
aligned directly through the community on El Camino Real. LRN 2 between
Greenfield and King City had been laid out as a 15-foot-wide highway
during October 1912; surveys for the route of LRN 2 from Greenfield to
Camphora were completed by July 1914. By 1917, the route was completed. By
the end of the 1950s, expressway conversion had commenced. The widening of
US 101/LRN 2 to four-lane expressway standards from 1.8 miles north of the
Salinas River to 2 miles south of Greenfield was budgeted for the 1957-58
Fiscal Year, and there was a second expressway project planned beginning 1
mile north of Greenfield to the Salinas River near Soledad. Design and
right-of-way acquisition for the US 101 freeway bypass of Greenfield
occurred in late 1959. The freeway bypass opened in 1961.
(Source: Gribblenation Blog (Tom Fearer), "Former US Route 101 on El Camino Real in Greenfield", August 2022)
Soledad (~ MON 61.392 to ~MON 63.259)
Surveys for the location of LRN 2 (future US 101) from
Greenfield to Camphora via Soledad were complete around 1914. By
1917, LRN 2 was aligned on today's Nestles Road to an at-grade crossing of
the Southern Pacific Railroad and Front Street, entering Soledad
northbound over the Salinas River via Nestles Road and Front Street.
Around 1932, construction planning began for a railroad grade separation
along US 101/LRN 2 in Soledad, including a 1.2-mile realignment of US 101/LRN 2 in Soledad. Construction started in early 1936 and was completed
later that year. The opening of the Salinas Underpass in September 1936
included a new alignment for US 101/LRN 2 on a southern extension of Front
Street to the Salinas River Bridge. In 1938, a new Salinas River Bridge
opened; this replaced a previous timber span constructed during 1914 that
was heavily damaged by a truck crash in 1934 and by a fire during 1935.
The roadway was widened to expressway standards in 1957-1958. The freeway
alignment of US 101 in Soledad opened in 1960. Much of former US 101 on
Front Street in Soledad was retained as an extension of LRN 120 and
provided a State Highway connection to the western annex of Pinnacles
National Monument. LRN 120 became the western segment of Route 146 in
1964.

Gonzales (~ MON 69.11 to MON 72.679)
Modern US 101 is aligned around Gonzales via a freeway
bypass that swings east of downtown. The original alignment of US 101 in Gozales was aligned directly through the community on Alta
Street. The original alignment dates back at least as far as 1917,
as Gonzales can be seen on the 1917 California State Automobile
Association Map along LRN 2 via Alta Street. The route was
reconstructed in 1933, as the existing highway was too narrow and
breaking apart too quickly. In 1954, US 101/LRN 2 was expanded to
expressway standards from Chualar south to Gonzales; 1957 saw the segment
from Soledad to Gonzales budgeted for conversion to four lane expressway
standards. By late 1961, construction of the freeway bypass of Gonzales
was underway; it was completed in 1963.
(Source: Gribblenation Blog (Tom Fearer), "Former US Route 101 on Alta Street in Gonzales", September 2022)
Chualar (~ MON 77.054)
Chualar can be seen on the 1917 CSAA Map along LRN 2,
which enters Chualar via what was likely part of Chualar River Road onto
Grant Street to avoid the Southern Pacific Railroad switching yard and
reservation. There were various reconstructions as the route was improved
by the state. By 1935, US 101/LRN 2 was aligned through Chualar via Grant
Street. By 1952, plans were underway to expand US 101/LRN 2 from
Spence Underpass to Chualar to a four-lane expressway; this opened on
November 30, 1951. The new northbound lanes of US 101/LRN 2 between
Spence Underpass-Chualar were used to provide relief to traffic while the
southbound lanes were being modernized. In 1956/1957, a freeway alignment
of US 101/LRN 2 through Chualar was under construction. This was
completed in 1958 and the former corridor of US 101 on Grant Street was
converted to a frontage road of the new Chualar Freeway. The freeway
alignment runs through what was once a Southern Pacific Railroad switching
yard.

City of Salinas (~ MON 85.083 to MON R90.913)
The initial route of LRN 2 (later signed as US 101) and
the El Camino Real through Salinas was as follows headed northbound
towards San Juan Bautista: (1) Abbott Street to John Street; (2) John
Street to Main Street in downtown Salinas; (3) Main Street through
downtown Salinas to the San Juan Grade. The early phase of the expressway
upgrades of US 101/LRN 2 are first mentioned in the January/February 1952
California Highway and Public Works Guide. The construction of the
expressway segment of US 101/LRN 2 (called the Salinas Freeway) within the
City of Salinas started in Spring 1952. By Summer 1953 the first phase of
the Salinas Freeway was nearly complete between the Spence Underpass (near
Hartnell Road) and Market Street. Traffic on US 101/LRN 2 would have been
routed on a temporary alignment via Market Street to the existing highway
on North Main Street north of downtown Salinas. It was likely around this
time that northbound traffic began to utilize Monterey Street from Market
Street to reach North Main Street under the Union Pacific (at the time
Southern Pacific) underpass. Conversely this would have transitioned
southbound traffic at the Union Pacific underpass on North Main Street to
Market Street. The Salinas Freeway bypass of Abbott Street, John Street,
and South Main Street effectively extended LRN 117 (post 1961 Route 68) to
US 101/LRN 2 via John Street. By Spring 1954, work was progressing on the
expansion of US 101/LRN 2 on the Salinas Freeway to from Market Street to
North Main Street. This new alignment of US 101/LRN 2 the Salinas Freeway
effectively bypassed downtown. The completion of the Salinas Freeway to
North Main Street effectively extended LRN 118 (later signed as Route 183)
to US 101/LRN 2 at the new interchange north of downtown Salinas. By 1961,
there was an adopted routing for the freeway between North Main Street to
Espinosa Drive; this routing opened in Summer 1965.

San Juan Grade and its Replacement (~ MON R90.913 to MON 98.464)
The graphic to the
right, posted on Facebook, shows the "proposed" highway route from Salinas
to San Jose in 1913. The city of Watsonville tried hard to get it through
their town, but it ended up going through San Juan Bautista, and later
through Prunedale. Note that this map shows the highway going over the San
Juan Grade.
(Source: Don Wilson on Facebook, 7/7/2019)
Old Stage Road was originally a spur of El Camino Real
from Salinas Valley over the Gabilan Range. It was originally a main route
for travel. Old Stage Road even by the conventions of the 1910s was
woefully inadequate for usage by automobiles. The terrain of the
Gabilan Range between San Juan Bautista and Salinas Valley was so rugged
that an alternate route from Gilroy to Salinas by way of Watsonville and
Castroville was considered when LRN 2 was being adopted as a state highway
after 1909. The rationale for selecting the routing of the San Juan Grade
through the Gabilan Range (referenced as San Juan Mountain) was
three-fold, as noted in the January 1913 California Highway Bulletin: (1)
the route through the Gabilan Range was the most direct route between
Salinas Valley-Santa Clara Valley, (2) was within seven miles of the San
Benito County seat of Hollister and (3) had an estimated gradient ranging
from 2-6%. The existing route over Old Stage Road is noted to be
direct, and it would be desirable for LRN 2 to follow nearby over a better
grade. By 1915, LRN 2 had been completed over the San Juan Grade
from the Monterey County Line north to San Jaun Bautista.
(Source: Gribblenation Blog (Tom Fearer), The Pinecate Rocks of US Route 101, 1/2023)
San Juan Road and San Juan Grade road were an routing of US 101 through San Juan Bautista (since bypassed). This is based on topological maps at http://sunsite.berkeley.edu/histopo/. Following the link to the Monterey Bay region, one can find two 15 minute topographic quadrangle maps for San Juan Bautista. The first, from 1917 reissued in 1932, shows the San Juan Grade road as "state highway" and does NOT show a road near the current alignment of US 101. The second, from 1939 reissued in 1958, shows US 101 near or on the current US 101 alignment. It may very well be that San Juan Grade Road and San Juan Road were an early alignment of US 101 from Salinas through San Juan Bautista; there is some logic in this based on the US highway system approach of running through the small towns in the area.
The map to the right shows approximately the pre-1932 routing in blue; contrast
this with the current US 101 routing shown with pale yellow. Note that it
appears the 1915 routing replaced an even older routing, which if you look
at a map closely, approximates the route along Old Stage Road from near
Penvir up to San Juan Bautista.
Tom Fearer did some more research on this, which he
reported on the Gribblenation blog. Specifically, there used to be a state
highway alignment running from US 101 south on San Juan Highway, through
San Juan Bautista, south over the San Juan Grade to Salinas, which was a
very old alignment of US 101, replaced by 1932. The San Juan Grade was
built in 1915 which presumably replaced Old Stage Road from Salinas to San
Juan Bautista. Presumably this was part of alignment adopted as LRN 2 from
San Francisco south to San Diego in 1909. This history can be seen on 1931
edition of the California Highways and Public Works Journal. By 1926 the
San Juan Grade became part of US 101. The San Juan Grade alignment can be
seen clearly on the 1930 State Highway Map. The San Juan Grade was
replaced by 1932 with the modern alignment of US 101 to the west at a
lower elevation through the Gabilan Range which can be seen on the State
Highway Map from said year. The San Juan Grade remained a unsigned state
highway (similar to routes like Route 14U -- essentially, a route not yet
relinquished and thus still maintained) at least until 1936 when it
appears to have been relinquished. The state maintained roadways on the
San Juan Grade are apparent on the 1935 San Benito and Monterey County
maps while it no longer present on the 1936 State Highway Map. From San
Juan Bautista, US 101 would have continued south of modern Route 156 along
The Alameda which is now the north terminus of County Sign Route G1. County Sign Route G1 quickly
branches off of The Alameda onto San Juan Canyon Road which climbs up to
Fremont Peak. The Alameda branches off onto Old Stage Road and San Juan
Grade Road; US 101 used the latter. Some additional history on the San
Juan Grade, and its predecessor, the Old Stage Road, may be found in Tom's
blog "Old Stage Road; the "real" El Camino Real and predecessor route to US Route 101 on the San Juan Grade".
(Source: Gribblenation: US_101 San Juan Grade)
The replacement for the San Juan Grade (known as the
"Prunedale Cutoff") is partly in Monterey County and partly in San Benito
County. The general location is on the coast route (US 101), about 100
miles south of San Francisco. The southerly end is two miles north of
Salinas and it passes through the villages of Santa Rita, Prunedale, and
Dumbarton. Its northerly terminus is at its junction with the existing
State highway three miles north of the mission town of San Juan Bautista
(i.e., this new segment runs from N of Salinas towards Gilroy, including
the junctions with Route 156 and Route 129). Instead of crossing the
Gabilan range of mountains, the new 1931 cut-off passes over mesas and
through a series of valIeys in the foothills of that range. There is a
saving in distance of 1.2 miles. The highest elevation reached is 550
feet, whereas the San Juan grade route is at an elevation of 1050 feet.
Contrasted with the San Juan Grade over the mountains, where frequent
sharp curves allow only a sight distance of 75 feet, the 1931 highway with
its long radius curvature and low gradient will permit motorists to travel
at all points at the highest speed. The CHPW noted that the old grade
would remain as part of the State highway system (which it did for a
time). The new highway construction project follows partly along the route
of the old "Camino Real" between Monterey and San Benito counties. It
passes through a narrow gorge known as the "Pinecate Rocks" in San Benito
County, interesting because in the bandit days of California, it was the
scene of many stage holdups. Footholes in a prominent rock are still
evident where bandits scaled it to hold up stages from a point of vantage.
Twelve acres additional right of way was obtained at "The Rocks" to
preserve for all times the beauties of this romantic spot. The CHPW
article noted that the new route is so located that connecting highways
could be constructed to bring the San Francisco Bay district much closer
to several cities of Monterey County. They noted that by the construction
of a highway between four and five miles long between the new road and
Castroville (which later became Route 156), several miles in distance and
much time will be saved to travelers between San Francisco and the
Monterey Peninsula. It noted that Monterey County is already building an
improved highway connecting the new route with Watsonville (eventual Route 129), and Watsonville will then be brought within nine miles of the coast
highway. It noted that the new alignment consists of a graded width of 40
feet in cuts and 38 feet on fills. The Portland cement concrete pavement
is 20 feet wide, is being laid in two 10-foot strips. Expansion joints are
placed every 60 feet with weakened plane joints at 20-foot intervals. It
is reinforced throughout against corner breaking and edge cracking. The
10-foot strips are 7 inches think in the center and 9 inches at the edge.
Where the roadbed conditions are more unstable, the pavement is thickened
to 9 inches in the center and 11 inches at the edges. Several wooden
bridges with concrete decks are included in the drainage structure.
Smaller drainage structures consist principally of concrete boxes and
corrugated iron pipes. The cost of the project will be nearly $1.000,000
and the new road would be open by Summer 1932.

San Juan Baustista Y (~ SBT 2.712 to SBT 3.145)
As noted above, the San Juan Grade was the original
routing of US 101 in this area. The July 1914 California Highway Bulletin
noted surveys for the San Juan Grade were complete in San Benito County
and in Monterey County, with LRN 2 from the Monterey County Line to San
Juan Bautista in the process of construction as an unpaved road. A
contract to construct LRN 2 in paved Portland Cement north of San Juan
Bautista was awarded on July 6, 1914. The year of 1931 featured the
construction of the Prunedale Cutoff that replaced the San Juan Grade as
the new alignment of US 101/LRN 2. The Prunedale Cutoff alignment of US 101 bypassed San Juan Bautista by way of the communities of Santa Rita,
Prunedale and Dumbarton, and was opened to traffic during the summer of
1932. The San Juan Grade was retained as a spur of LRN 2 east of US 101 on the Prunedale Cutoff. In 1935, planning was on going for a new
route for LRN 22 (future Route 156, which meets US 101) west of San Juan
Bautista to US 101/LRN 2 at the Prunedale Cutoff. This new route would
include a new Y junction (the San Juan Bautista Y). The original
route of LRN 22 on Rocks Road is referred to as "a winding county road"
that was immediately improved temporarily with an oiled earth application
upon being adopted in 1933. The new routing of LRN 22 west of San
Jaun Bautista is noted to negate the need for traffic to use the original
routing of US 101 via the San Juan Grade. The San Juan Bautista Y
was in line for future beautification that would include mission style
walls, a campanile and a cross. The completion of new routing for LRN 22
west of San Juan Bautista led to the relinquishment by 1936 of the San
Juan Grade from the State Highway System. The beautification of the
Y was completed by 1938.
(Source: Gribblenation Blog (Tom Fearer), "Former US Route 101 and California State Route 156 at San Juan Bautista Y", 12/2022)
In 1959, the new San Juan Interchange opened as a
replacement for intersection of US 101/LRN 2 and Route 156/LRN 22 at San
Juan Bautista Y. At the time, the San Juan Bautista Y had the
highest rate of accidents of any state highway segment in San Benito
County. The cross and campanile of San Juan Bautista Y were
preserved so they could be enjoyed by the traveling public.

S of Sargent / Betabel Siding (~ SBT 5.251 to SBT R6.679)
In the 1870s, the Southern Pacific Railroad plotted a
siding known as Betabel near the confluence of the Pajaro River and San
Benito River. Betabel and Y Road were ultimately incorporated as part of
the American El Camino Real which began being signed as an Auto Trail
starting in 1906. This eventually became part of the Pacific
Highway, later LRN 2 and US 101. The Prunedale Cutoff was opened to
traffic on July 20, 1932 and bypassed the San Juan Grade, San Juan
Bautista and the bridge over the San Benito River to the west. The
older alignment of US 101 was initially retained as a spur of LRN 2.
Then, in 1935, a new routing for LRN 22 (Route 156) west of San Juan
Bautista was constructed. This route went to US 101/LRN 2 at the Prunedale
Cutoff and new Y junction (the San Juan Bautista Y). The new
routing of LRN 22 west of San Jaun Bautista negated the need for traffic
to use the original routing of US 101 via the San Juan Grade. The
completion of LRN 22 west of San Juan Bautista led to the relinquishment
of the San Juan Grade and the San Benito River Bridge from the State
Highway System. This led to the bypass of Y Road.

Sargent (~ SBT R7.506)
State Highways in Sargent began with the 1909 First
State Highway Bond Act, which funded the Pacific Highway: a 481.8-mile
highway originating at the City Limits of San Francisco that terminated in
San Diego (LRN 2). In 1926, this became US 101. US 101 from Gilroy south
to the San Benito County Line at the Pajaro River was aligned on Monterey
Road through Sargent. In 1942, there were improvements along US 101/LRN 2
in the Gilroy area. The original Pajaro River Bridge near Sargent
was replaced, and the route bypassed the site of Sargent via the new
alignment. In 1949/1950, US 101/LRN 2 was widened south of Gilroy to the
Sargent Overhead. This project included a second Sargent Overhead
(completed during 1950) and widening of US 101/LRN 2 north to Gilroy to
divided highway standards. This project ultimately would bypass
Monterey Road from the Sargent Overheads to the vicinity of Route 25 with
the older highway becoming a frontage of US 101/LRN 2.
(Source: Gribblenation Blog (Tom Fearer), "Former US Route 101 through Sargent", 5/14/2023)
The route between Gilroy and San Jose approximates the original routing. The original routing still exists and is designated as Business Route 101,
and is "Monterey" Road. Post-1964, it was also part of Route 82.
Monterey Road began as a stage coach route in the 1850s, which connected
San Jose to Monterey. The towns of Morgan Hill and Gilroy grew up as stage
stops along the route. The road includes portions of the historic El
Camino Real (Royal Road) which was a 600 mile road that once connected
California's twenty-one Spanish missions. In 1909, the road became part of
the state highway system (LRN 2); signage would have started around 1926.
Following World War II, motor courts (motels) with attached cabins began
to appear, often with a U-shaped design featuring a central landscaped
area or swimming pool. Although many of these motor court style motels are
now gone, many still remain in San Jose, with a number of them along Monterey Road. By the early 1980s, US 101 was redirected to a new freeway to the east. Monterey Road
continues as an arterial road from San Jose (as a continuation of South
First Street where it crosses Alma Avenue) to the south county.
(Source: Ohare Devin in California Historic Highways on FB, 2/16/2019)
Gilroy was part of the American El Camino Real that began being
signed as an Auto Trail starting in 1906. In 1913, this became part of the
Pacific Highway. By 1917, CSAA maps were showing early LRN 2/American El
Camino Real/Pacific Highway on Monterey Street in Gilroy, with the western
terminus of LRN 32 (what would become Route 152) entering the city via Old
Gilroy Street. In 1933, LRN 32 was extended west from Gilroy via Hecker
Pass to Watsonville; it was signed as Route 152 in 1934. US 101/Route 152
multiplexed in downtown Gilroy on Monterey Street between Old Gilroy
Street/7th Street to 1st Street by 1935. By 1959, US 101 from Ford Road in San Jose south through Gilroy was being studied for
a potential freeway upgrade that would tie into the existing four lane
expressway segment south of Gilroy to the San Benito County line, which
was completed in 1951. By 1961 a freeway alignment had been adopted, and
the freeway upgrade was completed by 1972. This resulted in US 101 being
moved off of Monterey Street onto the modern freeway bypass. Route 152 was
shifted onto the new freeway between Exit 356/10th Street and
Exit 357/Leavesley Road. Route 152 followed Leavesley Road west to
Monterey Street where it jogged south to reach 1st Street. This
was completed by 1975.

The former terminus of the Bayshore Freeway (Blossom Hill Road (nee Ford
Road) junction with Route 82 (Monterey Road)) still shows some vestige of
the former Y interchange that fed the Bayshore into the older routing.
Here one can see where the freeway makes a sudden turn to the left at this
point, even though the Blossom Hill interchange is now a mere diamond.
This old interchange was removed in 1982, for the Caltrans bridge log
shows the bridges for the current CA 82/US 101 separation having been
built then.
(Thanks to Chris Sampang for this information)
In San Jose, the routing followed the present El Camino route that is present-day Route 82. This was signed as US 101 and was LRN 2. The present-day freeway routing was signed as Bypass US 101, and was LRN 68, defined in 1923. Construction began on LRN 68 in 1924, it was completed in 1929. The portion from 10th St. N was LRN 2.
In 1942, southbound Bypass US 101 did not continue down Bayshore Highway past Fourth Street (near the current I-880/US 101 junction) but went down Fourth, Reed, and Second to rejoin US 101 (First Street, now Route 82) near the current I-280/Route 82 junction. The Bayshore Highway continued only southeast from Fourth Street to McKee Road, where it became 30th Street (but reconnected to Monterey Highway). 30th Street has since been relegated to a non-continuous frontage road next to the Bayshore Freeway.
At the Rengstorff exit and around Mountain View, one can still see the old white-on-green BYP US 101 signs (with BYP greened out).
The segments of Grant Street in Santa Clara and Santa Clara Street/Market Street in San Jose appear to have been bypassed after 1968, as noted in this map. In Santa Clara, while what was named as late as 1968 as "Clay Street" east of Lincoln Street (now part of "El Camino Real" and was part of the pre-1964 US 101) remains on the route, the original alignment along what was then "Grant Street" (now part of a northwest extension of The Alameda from Camino Drive) was bypassed to make way for an expansion of Santa Clara University. Part of the original Grant Street/US 101/Route 82 between Franklin Street and Market Street has been supplanted by a pedestrian pathway through university property. Also, apparently in 1968, the US 101-era routing of Santa Clara Street directly to Market Street (instead of the modern Montgomery/Autumn and San Carlos path) in downtown San Jose was in use for Route 82 at the time.
There was evidently a study regarding double-decking US 101 up the pennisula, including all the way down to San Jose.
The June 1925 issue of CHPW noted that the Bay Shore Highway, from San Francisco to San Jose, was added to the state highway system. This changed the description of LRN 2 from "the county line of the city and county of San Francisco to and through the county of San Mateo" to "from San Francisco to the city of San Jose."
On US 101 near Moffet Blvd there are some bus cutouts. According to a posting on misc.transport.road, these were there to allow people to pick up soldiers, but their use is now discouraged, and they will be removed when the interchange is reconstructed.
East Palo Alto
In March 2021, there was an interesting article on what
was lost during construction of the freeways. The article noted that Route 101 had stoplights and no median strip and was considered one of the most
dangerous in the country, earning the nickname “Bloody
Bayshore.” The Division of Highways (forerunner of Caltrans)
transformed it into a freeway in stages between 1947 and 1958, eliminating
head-on crashes, according to the San Francisco Chronicle. Before that
time, Palo Alto and East Palo Alto were much more linked up. In fact,
there was a thriving downtown East Palo Alto along the four-lane highway,
including the art deco Auten’s Restaurant with a rocket-like tower
at the corner of Bayshore and University Avenue. Because Palo Alto banned
alcohol sales due to land restrictions placed by Stanford University,
restaurants and bars gravitated to the East Palo Alto side of San
Francisquito Creek. Auten’s special dinner boasted a top sirloin
steak, soup, salad, ice cream and coffee for $1.85. It was demolished for
freeway construction in the mid-1950s, along with a service station and a
Spanish-style house on University appraised at $14,430, a high price in
those days. After the freeway came through, the west side of East Palo
Alto became known as Whiskey Gulch. There was also a connection between
the freeway and racism, as noted by College of San Mateo historian Alan
Hynding in his book “From Frontier to Suburb”:
(Source: Climate Online, 3/16/2021)
“…(T)he Bayshore Freeway isolated the town from other communities to the west. As business investors, apprehensive about the black population and the high incidence of poverty and crime, avoided the area, the employment problem worsened. Like Watts and other West Coast black enclaves, East Palo Alto had become a suburban ghetto of deteriorating neighborhoods, where unemployment ran at about 40 percent … Poverty, unemployment and a heavy turnover in the population left the town without any real economic or political base, and without much civic pride.”
Construction also took a portion of the Charles Weeks
Poultry Colony, a chicken farm established in the 1920s as one of six such
communes, known as runnymeads (there were similar communes in Winnetka
(Los Angeles), CA). In Redwood City, the Bayshore ran along what is now
Veterans Boulevard, south of the current path. The Peninsula Celebration
Association had built a rodeo grounds for a two-day rodeo, part of the
annual Fourth of July festivities. Photos show a grandstand at the side of
the old highway, along with a racetrack, a hot dog booth, and a Wheel of
Chance. Construction of the freeway cut the grounds in two, and rodeo
ended in 1963. Proceeds from the sale of the land were placed in a fund to
support the annual parade and fireworks, which continues to this day. In
San Mateo, widening of the Bayshore and the need for an interchange with
Route 92 spelled the end for Henry’s Garage, which included an auto
wrecking business, service station, and tavern. Also demolished was the
private San Mateo Airport, which had been in the area since at least 1947
but had never gotten title to its land.

Bypass 101
There are also quite a few old alignments of Bypass
101 still existing:
(Source: Chris Sampang)
San Mateo and S of San Francisco
According to the San Mateo Daily Journal and theFeb
1925 CHPW, the predecessor to the Bayshore Freeway in the San Mateo
area was the old Bayshore Highway. Parts of this highway (El Camino Real,
once called the County Road) had already been built by the 1920s. The
initial contract was approved by the California Highway Commission in
1924, providing for the grading of a 5.2 mile section between South San
Francisco and Burlingame. These first 5.2 miles cost approximately
$400,000 to construct. Another source indicates that construction actually
began on Aug. 7, 1912, when Burton A. Towne, chairman of the State Highway
Commission, stood in front of a line of local officials and turned over
dirt that would soon be replaced by the first section of paved state
highway in California. The ceremony took place on El Camino Real near
Uncle Tom’s Cabin, a popular restaurant that dated back to the
horse-and-buggy era. The job, consisting of a paved road between South San
Francisco and Burlingame, was the first construction project of the
California Department of Transportation. In 1927, San Bruno could boast
about having the most traveled section of highway in California. State
Highway Commission personnel recorded the number of cars that used state
roads in July of that year and found that 29,338 vehicles ran over the San
Bruno section. Indiana Street in Los Angeles was second at 22,385. San
Bruno was the starting point because it wasn't incorporated: “The
decision to start here seems to have been influenced by the efforts of the
tri-county committee demanding that work commence with El Camino Real and
the fact that San Bruno was as yet unincorporated,” local historian
Joan Levy wrote. San Bruno incorporated in 1914. The tri-county committee
consisted of representatives from San Francisco and San Mateo and Santa
Clara counties. No state highway work could be done in incorporated
cities, which left San Francisco out when it came to the spending of the
$18 million approved in 1909 in Sacramento through California’s
first highway bond act.
(Source: San Mateo Daily Journal, 11/6/2017)
In
1926, this was incorporated into the new US Highway system as part of US 101. As the Bayshore Freeway began to be designated as US 101, El Camino
Real became known as the US 101 BYP. In 1931, the highway was completed to
Redwood City. The southern section to San Jose was finished in 1937. The
route of the old Bayshore began at 10th and Market in San
Francisco. It extended past the intersection at today's Cesar Chavez and
Potrero. It continued along what is now Bayshore Boulevard, which
parallels today's freeway until it intersects with Third Street. From
Third Street, the Bayshore Highway proceeded through “Boneyard
Hill”, continuing around San Bruno Mountain south of Brisbane,
extending through South San Francisco along what is now Airport Boulevard.
Airport Boulevard crosses under the freeway at the north end of San
Francisco International Airport. Cutting through the rich dairy land which
once comprised much of Millbrae, the Bayshore Highway rolled through what
is now a runway at SFO, then past today's hotel row in Burlingame,
stopping at Broadway in Burlingame. At that point, the highway followed
essentially the same route as today's Bayshore Freeway, until it reached
Redwood City. There, today's Veteran's Boulevard served as the highway
course, extending south to Marsh Road in Menlo Park. Beyond Palo Alto, the
old highway followed much the same configuration as the present US 101.
The first overpass over the Bayshore emerged at Peninsula Avenue, with the
interchanges at Ralston Avenue, Holly Street and Whipple Avenue
constructed later. By 1940, traffic congestion on El Camino Real led to
construction of a a 27-mile freeway from San Francisco to Palo Alto. By
1948, most of initial construction of the Bayshore Freeway from San
Francisco to Broadway-Burlingame had been completed. The second phase of
construction extended the freeway into San Mateo. By July 11, 1957, the
Candlestick causeway had been built over the water linking San Francisco
with San Mateo County. This section of the freeway was constructed through
the marshland from Candlestick Point and Oyster Point in South San
Francisco, including excavating a mountain and filling the marsh east of
Brisbane with landfill. Overall, 4,007,000 cubic yards of fill was used.
Full details of the fill project may be found in the Nov/Dec 1955 issue of CHPW. In 1964, with the great renumbering, the Bayshore Freeway gained the sole designation of US 101, while El Camino
Real became Route 82.
In Brisbane (up to the Bayshore district of Daly City),
the Bayshore Freeway takes a direct north-south path between the Cow
Palace exit and the SF county line; Bayshore Boulevard swings to the left
here because until the early 1960s, that was the actual SF Bay shoreline
in what is called the Brisbane Lagoon. When the Bayshore Freeway was
constructed here, part of the SF Bay was filled in for the freeway lanes
(and is now occupied by the freeway and by the Sierra Point Parkway); the
Brisbane Lagoon now is seperated from the rest of the Bay.

There is also, according to Chris, the possibility that Mission Road between Colma (originally known as Lawndale) and South San Francisco was once part of US 101. Chris did an analysis of a 1933 and a 1942 map posted by Mark Furqueron. In the 1933 map, US 101W takes a route that includes an intersection with Grand Avenue; the current El Camino Real alignment does not touch Grand Avenue. This is made clear in the 1942 map, suggesting that the current alignment of current Route 82 in South San Francisco was constructed between 1933 and 1942. As the Mission Road alignment first shown as bypassed a 1936 Gousha map, it's possible that this new routing around Colma Creek was constructed between 1933 and 1936, but not before 1933 at least. In the 1942 map, Mission Road intersects El Camino Real in "Baden Station", near the present junction of Westborough Boulevard/Chestnut Avenue with Route 82. This would mean that Chestnut Avenue's bridge over Colma Creek may have once been part of the US 101 routing, or a different bridge may have existed (Mission Road now ends in a T intersection with Chestnut). According to the CalTrans bridge log, the original Colma Creek bridge at the Mission/El Camino junction in Colma was built in 1913, and revamped in 1927 (thus suggesting that Mission Road may have only been a temporary routing before the Colma Creek bypass was finished).
According to the Millbrae Spur Project: In the 1920s, San Francisco and San Mateo Counties proposed a faster through route between San Jose and San Francisco. The Junipero Serra Highway went through the congested downtown area of southern San Francisco, west to Daly City, and ended in Colma. In the late 1930s, the route (now US 101) was extended to Sneath Lane in San Bruno. It then connected to El Camino Real via Sneath Lane. In the mid-1950s a section was added extending the route to Crystal Springs Road, at which point one traveled east to El Camino or west to Skyline Boulevard. The CHC intended to complete this road through Millbrae to Millbrae Avenue, and create a connector to the Bayshore. However Millbrae housing development conflicted with the proposed highway construction. In early 1955 the proposed route of the Junipero Serra Highway was reoriented in San Bruno to go to Skyline Boulevard and south to Ralston Avenue in Belmont. This was considerably west of the original route; it no longer divided the Peninsula cities. In the 1960s the route was again modified, and the proposed highway was absorbed into I-280.
Evidently, the route south from San Bruno was chosen for the first commemorative contract with groundbreaking on August 7, 1912. Why was it chosen? All the clout was in the San Francisco Bay area at the time - San Francisco, San Mateo, Santa Clara & Alameda Counties. There was a strong desire for a San Francisco to Los Angeles route, and they wanted it in place before the Panama Pacific International Exhibition planned for 1915. The Highway Commission announced they would not build in incorporated cities. El Camino was "shovel ready" and San Bruno was not yet incorporated.
San Francisco Routings
Here are some specifics on the routings (Tom Fearer also traces the routing in San Francisco in his blogs on the subject):
A good history of the route in the San Francisco Bay Area may be found in the article "History Traces the Bayshore from Highway to Freeway", from the San Mateo Community Journal. There was also an article in the San Francisco Chronicle on the building of the "Bayshore". That article noted:
The Bayshore construction project saw the first 2-mile stretch, from Broadway in Burlingame to Peninsula Avenue in San Mateo, completed in the summer of 1947, and it was followed in January 1948 by the 5-mile stretch north of Broadway to Colma Creek in South San Francisco. The first San Francisco stretch of the new freeway was a 2-mile stretch of elevated road running near Bryant Street to what was then Army Street. For the opening, Mayor Elmer E. Robinson donned goggles and severed a galvanized steel chain with an acetylene torch. Immediately, both ends saw traffic jams that could delay trips for an hour. Not everyone was thrilled with the change. Some residents felt restricted by a 6-foot fence built to keep pedestrians off the freeway. Buses could no longer stop along the route through Burlingame and drop off passengers “practically at their front door.” San Mateo, for its part, was unhappy with the newfound speed and formally requested that limits be set at 35 mph through the city’s section of freeway. The Division of Highways took bids starting April 4, 1954, on the last stretch of the freeway between San Francisco and the Peninsula, which included the 3-mile-long Candlestick Cove causeway to Sierra Point, bypassing the dangerous Tunnel and Boneyard hills, two hot spots which had contributed to the road’s “Bloody Bayshore” nickname. By 1958, with construction complete, the highway finally provided commuters a signal-free route between San Francisco and San Jose.
(Source: SF Chronicle, 7/11/2017)
The Hyde Park Ferry across San Francisco Bay has a large "Historic US 101" sign on it. At one point, ferries were considered part of the state highway system. Tom Fearer, in his blog Hyde Street Pier and the original surface alignment of US Route 101 in San Francisco, provides a good summary of the early routings in San Francisco and the connection the the Hyde Pier and Hyde Park Ferry.
The Central Freeway
In San Francisco, US 101 was routed on the Central Freeway, which starts at I-80 and ended on the northbound (lower deck) side at Franklin and Golden Gate. It then went via Golden Gate to its current routing on Van Ness. The southbound upper deck started at Turk and Gough, using Turk from Van Ness. In 1958, the 1.3-mile-long extension of the Central Freeway from South Van Ness Avenue to Turk Street was under construction, with completion expected for 1959. This section was a two-level elevated viaduct with the three southbound lanes carried above the three northbound lanes. It wasdamaged in the Loma Priata earthquake and it was only open to Fell and Oak at Laguna. US 101 exited the Central Freeway at Mission/Van Ness. In 1996, this segment was closed down to take out the double deck portion.
The history of the construction of the Central Freeway through Hayes Valley -- and the controvery associated with it -- is discussed in "The Birth And Life Of The Freeway In Hayes Valley". This also includes a discussion of the Embarcadero Freeway.
The Central Freeway had four sets of "ghost ramp" stubs off it:
The Mission Freeway
At one point, there was more freeway planned for US 101: it would have been the Mission Freeway: A freeway that looks like it ran down Mission Street from US 101 in Daly City to the present-day US 101 near Oak and Fell. This was more proposed freeway than anything actual; it certainly was not part of the state highway system by 1963. It appears that a portion of it (as San Jose Avenue) existed for about a mile or two north of I-280, with a couple of interchanges. It is more likely that this stretch is the remains of San Jose Avenue, which was built as a divided road beside the original (1860's-1870's) Southern Pacific main line (an article on this stretch may be found here).Later, the Ocean Shore RR and streetcar lines joined in, and starting in the early 1900's SP gradually abandoned the line after building the one Caltrain uses now. The RR(s) originally built the cut; the City later widened it and built roadways. Pictures from the 1950's and early 1960's show the overpasses built with a narrow space between pillars in the center (where the railroad/streetcar tracks were) paved over as a passing lane, with wider spaces on either side for the main road. In the 1960's or 1970's, the bridges were replaced for seismic and road reconstruction purposes with the full-width spans seen today. The only actual interchange is at Glen Park (Diamond St. - Monterey Blvd.) where it was built as part of the Southern Freeway project (I-280). Note that portions of this are currently maintained by the City of San Francisco, although the portion south of Rousseau is Caltrans.
Between the mid-1930s and 1964, there was also an Alternate US 101. This ran along the 1934 state signed Route 3 between San Juan Capistrano and El Rio (near Ventura), and is present-day Route 1. This was LRN 60, defined in 1919. In Southern California, this ran along Pacific Coast Highway, Palisades Beach Road (PCH in Santa Monica), Olympic Blvd (Route 26), Lincoln Blvd, Sepulveda Blvd, and PCH.
The Los Alimitos Traffic Circle was the point where Route 1/Former Route 3/US 101A/US 91 and Route 19/US 91 came together. The Los Alamitos Traffic
Circle was located at the junction of State Street, Bennett Avenue and
Hathaway Avenue. 1934 Route 3 followed the entirety of LRN 60, which
by proxy took it through Los Alamitos Traffic Circle in Long Beach.
CA 3 was renumbered as US 101A in 1935; the 1964 renumbering changed it to
the current Route 1. Also meeting in the traffic circle was Route 19/LRN 168, which in 1947 was cosigned with US 91. US 91 would also be extended
along US 101A to meet US 6. The Los Alamitos Traffic Circle originally
only had what is now the inner circle. The inner circle transitioned
the implied connection of Route 3/LRN 60 from Hathaway Avenue to State
Street (both were renamed by 1944 to Pacific Coast Highway). LRN 168
joined the traffic circle via Bennett Avenue, which is now Lakewood
Blvd. In 1942, the traffic circle was expanded and widened, with the
original plan being to have six highways enter it (however, only three
were constructed). The expansion added an outer ring which had been built
by the city of Long Beach and Los Angeles County. The original inner
Los Alamitos Traffic Circle was expanded to increase capacity on US 101A/LRN 60. In 1993, Caltrans reconfigured Los Alamitos Traffic Circle to
modern roundabout conventions. Route 19 was relinquished in the city
of Long Beach via AB 2132 Chapter 877 in 1998.
(Source: Gribblenation Blog (Tom Fearer), "Los Alamitos Traffic Circle; current California State Route 1/former US Route 101 Alternate and US Route 91", 2/7/2022)
A second Alternate US 101 (US 101E) existed in the San Franciso Bay area. This alternate diverged from US 101 in downtown San Jose, at approximately Alameda and Santa Clara. It ran along Santa Clara, and then along 13th St N to what is now Old Oakland Road. Later it followed the route of what was then Route 17 (original Route 13; LRN 69 (defined in 1933); present-day I-880) into Oakland. Briefly, the US 101 routing was signed as US 101W, and the Alternate US 101 routing was signed as US 101E. The US101E routing may have been the original 1926 US 101 routing. It appears the 101W and 101E designations disappeared with the opening of the Golden Gate Bridge.
There is a report that a 1934 Gousha map shows US 101E following US 50 from Oakland to Hayward, then along the route that is now Route 238 southward, not along the Route 17 alignment.
Former US 101 in San Diego, Orange, and Los Angeles County
Note: Although US 101 no longer formally exists south of downtown Los Angeles (although portions of the former routing are Route 72 and I-5), this section tracks significant activity along the former routing.
In February 2017, there was a report on the impact of roundabouts on
Former US 101 in the Community of Bird Rock near La Jolla. La Jolla Blvd,
once a stretch of US 101 as it wound from La Jolla to Pacific Beach,
handles an estimated 22,000 vehicles a day. This stretch of highway once
was traditionally straight, with left turn bays and street parking. Since
it has been converted to five single-lane roundabouts linked by two
relatively narrow 10-foot driving lanes, with angled parking on the west
side that doesn’t impede the southbound flow of traffic thanks to an
extra cushion for backing out, traffic flow has paradoxically improved.
Instead of waiting 24 seconds for a pedestrian to cross 72 feet of road,
drivers now only wait 3-4 seconds, or don’t have to wait at all.
Businesses that feared the loss of customers arriving in cars actually
improved their trade about 35 percent, new stores were built, noise levels
were reduced 77 percent, and the value of land within walking distance
climbed. Far more people started walking and bicycling. But, most
interestingly, motorists started driving 19 mph on 2.5 miles of La Jolla
Boulevard, instead of 40-45 mph, then stopping and stopping again. Today
motorists are getting to their destinations in less time, because they
aren’t stopping. The pity is that it’s so hard for communities
to accept the short-term pain of ripping out stoplights and stop signs,
the angst of assessments, disruptive construction. Easier to accept the
familiar squalor engendered by mind-numbing stoplights and barren streets.
Bird Rock, on the other hand, was ripe for the radical embrace of
roundabouts at the turn of the century because it was so fed up with being
La Jolla’s poor relative united by an ugly and dangerous speedway.

In February 2017, it was reported that there is a growing movement to
transform former US 101 (Coast Highway) in North San Diego County into
something more bicycle and pedestrian friendly. From Del Mar to Oceanside,
cities are looking to slow traffic, widen bike lanes and implement other
changes that encourage people to get out of their cars and use alternate
forms of transportation. Solana Beach finished an overhaul its portion of
Coast Highway in 2013, completing a $7 million project that converted the
road to narrower lanes with wide sidewalks, gathering spaces and buffered
bike lanes. Encinitas made changes in Leucadia, reducing traffic lanes and
adding “sharrows” — large white markers painted on the
asphalt — to remind drivers to slow down and share the lane. Del Mar
and Oceanside are studying similar changes, hoping to better accommodate
bicyclists and pedestrians and create a more vibrant environment for
businesses and residents along the coast. However, there are (as they say)
bumps in the road. After a re-striping pilot program was launched in 2016
in Oceanside — reducing parts of Coast Highway from two to four
lanes, and adding wider bike lanes — more than 400 people signed a
petition against the changes. Del Mar is another town where the idea has
run into trouble. City planners have proposed reducing northbound Camino
del Mar — the name for Coast Highway in that city — from two
lanes to one between Carmel Valley Road and Fourth Street. That prompted a
letter-writing campaign from residents early this year. A few supported
the plan, but most said the narrower road would worsen congestion and
force more traffic onto the parallel residential street of Stratford
Court. A back-up freeway isn’t the vision that many city planners
have for the historic road. Instead of escorting drivers out of town, they
see the coastal route as a way to invite people in, to stop and shop, ride
bicycles, enjoy the beach, and maybe meet some new people or old friends.
Leaders of the region’s robust cycling community say slowing traffic
and improving bike lanes along former US 101 will ultimately improve the
quality of life for all.

Sixth Street Viaduct (~ LA S0.332)
In February 2016, US 101 was shut down for 40 hours to remove the Sixth Street Viaduct (approx LA S0.332). A chemical reaction inside the iconic 84-year-old bridge is causing it to slowly crumble, and crews have been working for months to begin the demolition process. A portion of the bridge passes over US 101 and cannot be removed with traffic zooming underneath. Construction on a $449-million replacement for the 6th Street Viaduct is expected to last until 2019.
In December 2016, an update was provided on the
reconstruction of the Sixty Street Viaduct. The Downtown News reports that
the project is now expected to cost an additional $36 million—and
take eight months longer to complete. The newspaper cites city documents
that show the project, previously planned to cost $446.6 million has a new
estimate: $482.2 million. The bulk of the $36 million (about $21 million)
is associated with a newly extended construction schedule. Partly to blame
for the delay, she said, are restrictions associated with the railroad
tracks that run directly through the project area. (There are nine tracks
on each side of the river used by five different rail entities. This
element of the project was always expected to be complex.) The replacement
bridge was supposed to be up in late 2019. Now, the project is expected to
be complete by the end of 2020.
(Source: Curbed LA, 12/22/2016)
In April 2021, it was reported that a 2.5-mile section
of US 101 from the I-10/US 101 split to the I-5/I-10/US 101 interchange
just east of downtown Los Angeles was shut down for a weekend at the
beginning of May 2021 to allow for the construction of two arches. The
construction of the arches is part of the $558 million Sixth Street
Viaduct Replacement Project. The closure will also allow Caltrans to
repair guard rails, signs and pavement in the area, and fill potholes,
while a contractor will repair broken slabs in the southbound lanes. As of
the end of the May 2021 closure, the Los Angeles Department of
Public Works reported that the city has now completed six of the 20
monumental arches on the Sixth Street Viaduct. Of those 20, two pair are
60-feet tall, one pair (over the 101 Freeway) are 40-feet tall, and seven
pair are 30-feet tall. The Viaduct includes ten sets of LED-lit,
color-changeable arches that will make up “The Ribbon of
Light” design of the bridge. The arches are 10 feet wide, with a
typical arch span of 300 feet. Each arch takes 260 cubic yards of concrete
to construct or about 65 trucks of concrete. In order to keep the concrete
cool enough, it is delivered to the site, then injected with liquid
nitrogen to keep it close to ambient temperature. This reduces the
potential for concrete cracking.
(Source: CBS LA, 5/1/2021; Streetsblog LA, 5/12/2021)
In October 2021, there was another freeway
closure—this time to remove falsework. The arches over US 101 are
now fully supported and no longer require any additional support from
falsework under the bridge.
(Source: KTLA, 10/20/2021)
In May 2022, a good description of the design was
posted. From the east, it straddles the I-5 before hitting the US-101,
where the first pair of arches rise 40ft to form what feels like a
gateway. Then come five pairs of 30ft arches, passing a low-rise warehouse
district, then hitting the first set of railway tracks that flank the
river. Here two pairs of arches rise to 60ft, forming a symbolic echo of
the original structure. Drivers may be stuck in snarl-ups, but at least
the views – of the towers of downtown to the west, of the San
Bernardino mountains to the east – will be elegantly framed by
Maltzan’s gymnastic arcs, which somehow have LA in their DNA,
recalling the sinuous supports of LAX airport’s space-age Theme
Building. Those on bikes, meanwhile, will have the pleasure of spiralling
down a corkscrew ramp to a new 12-acre park, that will begin construction
beneath the viaduct in Summer 2022. The original bridge had a
problem: the sand that was used in the mix turned out to have a
lethally high alkali content, reacting with the cement to cause expansion
and cracking. By the 2010s, officials calculated the bridge stood a 70%
chance of collapsing in a major earthquake within the next 50 years. The
new structure has a wider deck incorporating cycle lanes and more generous
sidewalks, with its concrete arches now safely supported on seismic
absorbers – allowing it to move up to 30 inches in any direction.
(Source: The Guardian, 5/25/2022)
In June 2022, it was reported that the new viaduct was
opening July 9. The $588-million structure, which spans 3,500 feet across
the L.A. River between Boyle Heights and the Arts District in Downtown Los
Angeles, opened to the public in a two-day celebration on Saturday, July 9
and Sunday, July 10.

LinkUS (Link Union Station) Project (~ LA 0.528)
In February 2018, it was reported that LA Union Passenger
Terminal / LA Union Station (LAUS) is considering plans to add a new
southern entrance/exit for Metrolink and Amtrak trains and build a new
expanded passenger concourse. The Link Union Station project (Link US)
will transform the historic LAUS from a “stub-end,” or
dead-end station, to a “run-through” station by extending
tracks south over US 101, resulting in reduced passenger wait times. The
estimated $2 billion-plus project would also add a new loop track to
improve operational flexibility for rail service. Project officials say
these modifications will "significantly enhance the station’s
efficiency and enable LAUS to continue to serve as a major hub for local,
regional, and interstate transportation." The new concourse would replace
the current tunnel under the Metrolink, Amtrak and Gold Line train tracks.
The current tunnel is showing signs of age, is prone to overcrowding, and
lacks passenger amenities.
(Source: ENR California, 2/8/2018)
In January 2019, it was reported that an Environmental
Impact Report (EIR) and an Environmental Impact Statement (EIS) were being
prepared pursuant to the California Environmental Quality Act (CEQA) and
the National Environmental Policy Act (NEPA) for the Link US project to
comply with state and federal environmental requirements, respectively.
The Link US Draft Environmental Impact Report (EIR) would be available for
public review from January 17 to March 4, 2019. Both of the build
alternatives include up to 10 run-through tracks over US 101. With respect
to US 101, the Draft EIR notes that the project would include the following
bridges, viaducts, and structural improvements:
(Source: Link Union Station DRAFT - Environmental Impact Report State Clearinghouse No. 2016051071 January 2019; Link Union Station Project Page)
With respect to the US 101 viaduct, the DEIR notes:
In the interim condition, a new viaduct over the El Monte Busway and US 101 would be constructed with a deck wide enough to support two run-through tracks in the interim condition, up to six regional/intercity rail tracks in the full build-out condition, and up to 10 run-through tracks in the full build-out condition with HSR (common viaduct/deck).
The US 101 viaduct within Caltrans ROW would be approximately 283 feet wide, 736 feet long, with a deck elevation that varies between 294 feet and 313 feet in height. The height of the structure would vary from 17 feet to 36 feet in height, depending on location. The US 101 viaduct would be supported by two abutments and on nine bents located at the south end of LAUS, between the El Monte Busway and US 101, at the freeway median, and on the south side of US 101 ROW. Bents supporting the US 101 viaduct would also be located within the median and sidewalks of the newly realigned portion of Commercial Street at the location of the crossing. The close spacing of the columns along this segment would require Vignes Street between Commercial Street and Ducommun Street to be permanently closed to vehicular traffic.
The width of the US 101 viaduct would taper down and become narrower as the structure crosses US 101 and continues east toward Vignes Street. The US 101 viaduct would meet the vertical clearance requirements of the El Monte Busway and US 101 (16.5 feet minimum clearance) and the loading requirements per Metrolink, Amtrak, and CHSRA standards. Metro may apply aesthetic treatments to the US 101 viaduct in coordination with Caltrans and the City of Los Angeles.
The DEIR also notes the following improvements to be made to US 101:
US 101 Main Line
- Increased median width and shoulder widths for enhanced horizontal clearance
- Increased horizontal stopping sight distance
- Restriping main line for enhanced curvature
- Increased lane widths
- Increased weaving distance with maximized lengths between southbound Los Angeles Street on-ramp and southbound Commercial Street off-ramp
- Increased tangent length between reversing curves for improved drivability (greater distance between curves allows the driver to see the upcoming horizontal curve, prepare for the curve ahead, and adjust driving/steering accordingly)
Alameda Street Off-Ramp (Northbound)
- Increased deceleration length
- Standard ramp exit with diverge angle (provides a safety zone for drivers making last-minute decisions)
- Increased shoulder width for enhanced horizontal clearance
Commercial Street Off-Ramp and On-Ramp (Southbound)
In June 2019, it was reported that Metro's Board of
Directors this morning finalized environmental review of the Link Union
Station project, which will upgrade the 80-year-old station with new
“run-through” tracks over US 101.
(Source: Curbed LA, 6/27/2019)
In August 2019, the CTC accepted the Final
Environmental Impact Report and Statement of Overriding Considerations and
approve the Project for future consideration of funding. The Project will
construct new lead tracks and will convert the station into a
“run-through track station” instead of a “stub-end track
station” to accommodate a modified expanded passageway, new
passenger platforms on an elevated rail yard, tracks over the US 101
freeway, new rail communications, and other safety enhancements. The
Project is located on Alameda Street in the City of Los Angeles, Los
Angeles County. The Project is estimated to cost $950,398,000 and is fully
funded with Transit and Intercity Rail Capital Program Funds
($423,335,000), Proposition 1A High Speed Rail Funds ($398,391,000), and
Local Funds ($128,672,000).

In December 2020, the CTC approved the following
Transit and Intercity Rail Capital Program (SB1 Augmentation for PTA)
allocation: $67,336,000 for PS&E for (2018: 27) Southern
California Optimized Rail Expansion (SCORE) (Link US). Design work
includes a retaining/sound wall in the throat of Los Angeles Union
Station, two new run- through tracks from Platform 4 to the mainline
tracks on the west bank of the LA River, a new viaduct to
accommodate up to nine run-through tracks over the US 101 freeway,
Main Street Quiet Zone Ready improvements, utility relocation and street
improvements, and pedestrian and bicycle improvements. Outcome/Outputs:
Reduction of greenhouse gas emissions, increased ridership through
improved frequency and expanded service by providing 30-minute
bi-directional commuter rail services on the highest ridership segments of
the Metrolink system, including system-wide supporting infrastructure
improvements, as well as improved integration with other transit and rail
services, including Amtrak, OCTA bus, AVTA and LA Metro bus and rail
services. Includes access of services for priority populations throughout
Metrolink’s service area. (Future consideration of funding approved
under Resolution E-19-78; August 2019.)

In May 2022, it was reported that in a vote taken at
the end of May, the Metro Board of Directors approved a funding agreement
with California High Speed Rail Authority for the initial phase of Union
Station's $2.3-billion makeover and expansion. The project, called Link
Union Station, expands upon a longtime plan to construct run-through
tracks at the southern end of the passenger rail hub, allowing trains to
cross over the US-101 freeway. This would eliminate Union Station's
historic stub-end layout, which forces all trains to enter and exit
through the five-track throat to the north of the station platforms. The
vote by the Board adopts an agreement with the High-Speed Rail Authority
for roughly $423.3 million in funding for the first phase of the project,
as well as a $297.8 million preconstruction budget. That money will go
towards the construction of a new viaduct over the freeway and two initial
run-through tracks. Not included in the initial phase are some of the
pricier items in the scope of Link Union Station, including additional
run-through tracks, a new passenger concourse, and raising the main
platform area to provide clearance above the freeway.

Downtown LA Cap Park (~ LA 1.015)
Caltrans is also talking another park proposal. This would be a massive park and development project atop
what is known as the Slot, the below-grade section of US 101 that runs
between the Civic Center and Chinatown (approx LA 1.015). According to Caltrans, the idea would be to cap about a half-mile of US 101 just
east of Route 110. Curently, there are no firm plans for the cap, nor a
cost estimate. The project was developed in 2008 by 24 interns with
international design firm EDAW. They worked here for two weeks and
produced a design for Park 101, a revolutionary urban design solution to
create a leafy oasis in the downtown urban core. The next step for the
Park 101 Steering Committee is to obtain sponsorship and funding.
In September 2013, City Council members voted 14-0 to approve the motion introduced by Councilman Jose Huizar (PDF) on July 30 to seek funding from private, federal and state grants for the Downtown Park 101 Freeway cap park project, which would connect the Civic Center with Olvera Street, Chinatown and Union Station.
In June 2017, an update was provided on the Downtown
Park. A PowerPoint presentation from the Friends of Park 101, the nonprofit working to make the park happen, was released that shows off some preliminary ideas about how the final product
might look with renderings and programming by SWA Group. The slides show
each block within the cap park having a different theme. “The
Hill” section would have a viewing deck and native plants; “LA
Courtyards” would feature a pavilion and shaded terraced seating,
plus a playground. “The Plaza” section would have trees,
flexible open space to host more sprawling public events, and some kind of
water feature. “The Mercado” is geared toward hosting cultural
events and outdoor markets, and would have decorative pavers on the
ground. Urbanize LA has reported the cost to build the park is estimated
to be about $180 million. In its proposal, Friends of Park 101 suggest
maintenance could be paid for by developing six adjacent city- and
county-owned properties with a variety of uses, from adding storefronts to
building mixed-use properties. The so-called cap park—which would
extend between Hill and Los Angeles streets over the freeway—is
included in both the Union Station Master Plan and the Downtown LA
Community Plan update, adding legitimacy to the proposal.
(Source: Curbed LA, 6/20/2017)
At the end of May 2018, Curbed LA posted some images about how the completed park might look, including an animated GIF.
In February 2022, it was announced that as part of
Gavin Newsom’s $1.1 billion Clean California initiative, Caltrans is
awarding funding for beautification projects along the state highway
system. One project is the U.S. Route 101 Lankershim to Beaudry
Beautification (~ LA 1.735 to LA 10.36). The project will
beautify the landscape areas of the on/off-ramps, and slopes along US 101
in Los Angeles County from Lankershim Blvd to N. Beaudry Ave. A
decorative sculpture and rock design, California native plants and new
decorative colored concrete will be installed. Overhead signs will
be enhanced by removal of barbed wire and installation of dimpled sleeves
on columns, and irrigation will be upgraded for water conservation and
theft prevention. Estimated cost: $3.151 million. Estimated
completion date is April 3, 2023.

Hollywood Freeway Central Park
There's a plan afoot to build a park atop the Hollywood Freeway in Hollywood. This would roughly be over the freeway between Western and Franklin (approx LA 5.829 to LA 7.136). Details are on Curbed-LA. The plan is called Hollywood Freeway Central Park. The project hopes to start the environmental impact review process in the first quarter of 2012, with the Bureau of Engineering as the lead agency (previously, Caltrans was the lead agency). The project also says that a working group with members from Bureau of Engineering, the Community Redevelopment Agency of Los Angeles, Councilmember Eric Garcetti's office, and the Friends of the Hollywood Central Park has been meeting since May 2011 to prepare for the EIR.
In August 2014, Friends of Hollywood Central Park, the
group spearheading the plan, indicated that they have started the first
official step—the environmental review process. The 38-acre park
would run over about a mile of highway, from Santa Monica Boulevard
(approx LA 5.558) to Bronson Avenue (approx LA 6.641), and hopefully
create a street-level urban park that reunites communities separated by
the Hollywood Freeway more than sixty years ago. The notice about the
environmental review says the park will be open seven days a week, 24
hours a day, with potential features including "pedestrian meadows, small
retail facilities (such as bike shops, seasonal markets, and art
galleries, restaurants, an amphitheater, a community center, playgrounds,
dog parks, and interactive community areas." Development of the park is
expected to go in phases, from north to south, starting above Sunset with
"an amphitheater, parking, terraces, restaurants, a bed and breakfast inn,
a grass area, and a dog park." The environmental process kicks off in
September 2014 with a public scoping session to collect ideas on what
people want to see reviewed. The EIR process is expected to be finished by
2015, at which point a plan will be presented to the public for review.

Tony Curtis Mural
In October 2011, the Tony Curtis mural on SB US 101 at Sunset (approx LA 6.241) was removed. This was done
by the artist after 16-years of re-touching the mural after numerous
vandal attacks, and after a recent repainting of the mural. It was painted
by George Sportelli of Whittier, who indicated in October 2011, “I
decided about a year or two ago that I needed to relocate this mural
because I didn't intend to spend the rest of my life cleaning graffiti off
of it.” Originally painted in 1995 by Sportelli as part of Caltrans
Transportation Art Program, the mural has stood as an easy reminder to
motorists that they are passing through Hollywood or the city's creative
nature. The current mural will be installed on a building at the Shiloh
Horse Rescue near Las Vegas which is owned by Curtis' widow, Jill Curtis.
A replica mural has been relocated to the exterior of Liquor to Go-Go on
the corner of Hollywood Boulevard and Bronson.

Universal Studios Improvements (approx LA 9.223 to LA 10.36)
In 2006, NBC/Universal proposed a series of new plans for developments and improvements at the Universal Studios property. These plans include an extensive package of transportation proposals they say are designed to enhance mobility throughout Universal City and the community. The improvements under consideration include: a shuttle system from Universal Village and throughout Universal City to the MTA station; construction of a North/South "Great Street" through Universal Village connecting Forest Lawn Drive to Coral Drive; freeway and access improvements including possible construction of a southbound entrance to US 101 from Universal City. Also under consideration are a single-purpose urban interchange (SPUI) near Campo de Cahuenga connecting to US 101, and other system improvements to the US 101 corridor and the Route 134 interchange. Barham corridor improvements including the modification of the intersection at Forest Lawn Drive and Barham Boulevard and the possible widening of the Barham Bridge at the L.A. River; the enhancement of the pedestrian crossing at Lankershim Boulevard and Campo de Cahuenga, and various traffic signal system upgrades and intersection enhancements.
In December 2014, it was reported that local residents were upset about a
portion of the Universal Studios plan: specifically, the fact that the SB
US 101 off-ramp at Barham Blvd would be removed, due to interference with
a new SB US 101 on-ramp planned from Universal City directly onto US 101.
With the ramp closed, southbound drivers trying to get off US 101 will
have to exit north of Barham at Lankershim Boulevard or drive two miles
south to the next offramp at Highland Avenue, a major artery for the
Hollywood Bowl that backs up during performances. As part of the
NBCUniversal Evolution plan — which was approved by both the city
and county — a new southbound US 101 onramp would be built on
Universal Studios Boulevard, allowing departing park guests to get
directly onto the freeway, bypassing the neighborhood. The California
Department of Transportation determined that the Barham offramp had to
close. Otherwise cars accelerating from the new onramp and those
decelerating to make the Barham exit would create a dangerous stretch of
"weaving and merging," according to the project's environmental impact
report. The new Universal Studios Boulevard onramp is now under
construction and expected to open by early 2016. The Barham offramp will
close before the new ramp opens. The Barham Boulevard onramp to southbound
US 101 will remain open. More than 1,500 people have signed an online
petition protesting the offramp's closure. Essentially, there will be less
traffic in the area, but residents will have to get off the freeway one
stop before or after the Barham exit, which could be a little
inconvenient. And since this is LA, naturally, there are residents who are
proclaiming the closure "an abomination." In January 2015, the residents
filed a lawsuit claiming that NBCUniversal and Caltrans broke state law by
inadequately studying the environmental effect of the closure plan. The
lawsuit seeks to halt the Barham closure until further study is done.

In October 2015, it was reported that the southbound
Barham offramp was permanently closing early. This was one of the expected
casualties of the $1.6-billion NBCUniversal Evolution expansion; the ramp
had to close to make way for a new onramp that will feed Universal guests
directly onto southbound US 101. The ramp was scheduled to close in spring
of 2016; with construction ahead of schedule, Caltrans was able to close
it early. NBCUniversal says the new onramp will take 70 percent of
Universal Studios traffic off local streets. Even so, nearby residents are
pissed—now, US 101 commuters can either exit early at Lankershim and
drive local streets or drive farther south and deal with the traffic at
Highland Avenue in Hollywood. Both options are less than ideal for those
used to having an offramp close by.

TCRP Project #48 is a study to improve the US 101 corridor between Route 170 (approx LA 11.77L) and Route 23 (approx VEN 0.696). Many of these ideas will never happen. There is also a proposal for short term measures, such as adjusting city streets.
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $320,000 for High Priority Project #1955: Improvements to US 101 ramps between Van Nuys Blvd (approx LA 15.926) and Winnetka Ave (approx LA 23.268).
San Diego Freeway Interchange (approx LA 17.149L)
In September 2000, the California Transportation Commission considered a proposal (TCRP Project 51) to add an auxiliary lane and widen the ramp through the I-405/US 101 freeway interchange in Sherman Oaks. For phases 1 and 2, the request was for $4 million, with a total estimated cost of $34 million.
There is also work afoot to address another problem at that interchange -- specifically, the connector between southbound I-405 and the northbound US 101. This might involve construction of an elevated two-lane connector. There are five options currently under consideration, some of which could affect nearby homes or take out part of the Sepulveda Basin wildlife refuge. The connection between two freeways is now just one lane and often backs up on I-405. The project would build a two-lane connector across the Sepulveda Dam spillway, and could possibly include changes to southbound I-405 and the southbound US-101 interchange, and the Burbank Boulevard on-and-off-ramps.
Note that in the San Fernando Valley, portions of the route are labelled as east/west instead of (or sometimes, in addition to) being north/south. Presumably, this is to simplify directions for local travellers, who don't see the route as running North/South

In September 2022, the US 101 was closed for portions
of a weekend while the Encino Pedestrian Overcrossing was removed. The
overcrossing was built in 1959 over US 101, but the bridge no longer met
necessary “vertical clearance.” Caltrans officials do not plan
to reconstruct a new pedestrian pathway to replace the bridge — as
was initially proposed — following a years-long review process that
took input from residents who live nearby. Many said they did not want to
see a new bridge built, but instead preferred walkability improvements
along Louise Avenue, which crosses above US 101 about a quarter-mile east
of Encino Avenue. Caltrans is currently working on plans to upgrade nearby
crossing points along the corridor, including at Louise Avenue, to ensure
pedestrians and bicyclists have improved and safer access across US 101.

Lost Hills Bridge (approx LA 31.921)
In March 2015, groundbreaking occurred for the new Lost
Hills Bridge in western Calabasas. When it’s completed in 2017, the
new Lost Hills bridge will have five traffic lanes, two bike paths and a
sidewalk, making the passage across the 101 Freeway safer for pedestrians,
cyclists and drivers. The Lost Hills interchange is a main access point
for drivers traveling to western Calabasas and Malibu. The bridge carries
almost 30,000 vehicles each day and is considered too small for the high
demand. The project includes the construction of a curving on-ramp in the
northeast quadrant of the interchange, and a sound wall and earthen berms
to reduce traffic noise for residents of Saratoga, a community immediately
north of the freeway and west of Lost Hills Road. Two-thirds of the cost
of the $30-million project will be covered by the county’s Measure R
transportation bond funds.

In September 2016, it was reported that northbound
off-ramp for Exit 33, Lost Hills Road, has been completely rebuilt and has
reopened. Instead of a standard diamond interchange like before, it is now
a long ramp that veers to the right, meeting Lost Hills Road quite a ways
north of the freeway.

Liberty Canyon Wildlife Bridge (approx LA 32.795)
In September 2015, it was reported that state agencies, elected officials and wildlife
advocates urged the state to provide a much-needed link for wildlife near
Calabasas via a 165-foot-wide, 200-foot-long overpass across US 101 near
Liberty Canyon Road. This "wildlife bridge" would connect the Santa Monica
Mountains on the south with the Simi Hills and Santa Susana Mountains. It
would be an ambitious overtaking, as the highway has 10 lanes of pavement,
including exit lanes, at that point. Scientists long ago identified
Liberty Canyon as the optimal location to build a wildlife passage because
of the large swaths of protected public land on either side of the
freeway. In September, the Mountains Recreation and Conservation Authority
released a long-awaited study by Caltrans concluding that a wildlife
overpass was feasible. The projected cost would be $33 million to $38
million, according to the report. Proponents said they plan to seek most
of the money from public coffers. In the past, large carnivores have found
US 101 to be a formidable barrier. Since National Park Service biologists
began researching mountain lions in the Santa Monica Mountains in 2002,
motorists have struck and killed a dozen of the big cats in the study
area, including a male puma hit on US 101 near Liberty Canyon two years
ago. The report was the necessary first step toward a final design.
Caltrans is expected soon to begin preparing the required environmental
document, to be funded by a $1-million grant from the State Coastal
Conservancy. The public would be asked to weigh in during this phase,
which would run through 2017. The National Wildlife Federation and the
Santa Monica Mountains Fund have launched an initiative to raise funds for
the engineering design and construction expenses. The overpass would
feature drought-tolerant vegetation placed so that it helps funnel
wildlife across. Hikers, mountain bikers and equestrians would also be
able to use the structure.
(Source: LA Times, 9/2/2015, Image source: Adapted from a Living Habitats/NWF Image in CBS LA, 10/21/2020)
In January 2016, it was reported that Caltrans and the
National Wildlife Federation were hosting meetings to inform residents
about the options for a new wildlife crossing in Liberty Canyon. Barbara
Marquez, senior environmental planner for Caltrans, said plans to augment
an existing tunnel under the freeway were rejected. Environmentalists are
calling for safe passage over the freeway that would allow animals to
expand their territory from the Simi Hills and Sierra Madre Mountain
ranges in the north to the Santa Monica Mountains in the south. Two
options for the project, one costing an estimated $50 million, are being
considered. The first would include a 165-foot-wide by 200-foot-long
bridge across the freeway just west of Liberty Canyon Road. Noise barriers
and vegetation would help block noise and light from the freeway and
surrounding developments and blend the overpass into the existing
landscape. A second, more expensive alternative that received support from
the Old Agoura Homeowners Association would be similar to the first, and
would place the crossing over the freeway as well as at Agoura Road to the
south. “The slope between the end of the bridge and Agoura Road
would be built up before descending to join existing ground,” a
Caltrans report stated. “The expectation is that the crossing
extension would help alleviate wildlife impacts and mortality on Agoura
Road.” Environmental studies on the wildlife crossing will continue
until June 2017. Design issues will be evaluated with public input. The
last phase, June 2017 to April 2019, will finalize the design plans,
obtain construction bids, and acquire property rights and environmental
permits. The hope is that the bridge will be finished and ready for
wildlife crossings by November 2021.

In March 2016, it was reported that opposition was
starting to the Liberty Canyon crossing bridge. On 2/25/2016, the City of
Calabasas hosted a meeting titled “101 Freeway Wildlife Crossing:
How Does It Benefit You, Your Business and the City?” About 200
people came to Founders Hall to hear details about the financing, timing
and feasibility of the proposed catwalk and how it will benefit the local
mountain lion population and other wildlife. Most people cheered the
prospect of having a state-of-the-art wildlife crossing in their
community, but some aren’t so keen on the idea, saying the benefits
to wildlife are unproven and the money could be better spent elsewhere.
Panelists told the audience that the wildlife corridor will not divert any
funds from transportation, road repairs and other public uses. Much of the
cost will be met through private and corporate donations. Only those
public funds earmarked for wildlife protection will be used for the
project.
(Source: TO Acorn, 3/3/2016)
In October 2016, it was reported that advocates have
launched a campaign to raise private donations for the wildlife span over
10-lane US 101 in Agoura Hills that would provide safe passage to mountain
lions and other wildlife moving between the Santa Monica Mountains and
inland habitat. The effort got a jump-start from the Annenberg Foundation
in mid-October when the philanthropy announced a challenge grant that will
match every dollar, up to $1 million total, donated by other foundations.
A 2015 Caltrans report presented two alternatives for the US 101 crossing,
which would rise immediately west of Liberty Canyon Road. A bridge
that’s 165 feet wide and 200 feet long would cost $30 million to $35
million. A longer span over the freeway and Agoura Road — the choice
of wildlife advocates — would cost $50 million to $60 million. Given
California’s highway construction backlog, Judge said proponents are
seeking state conservation money, rather than transportation funds. Last
year, they obtained a $1-million grant from the California State Coastal
Conservancy. Backers want to raise $10 million from public and private
sources by the end of next year to advance the project, which they hope to
build by 2021.
(Source: LA Times, 10/19/2016)
In May 2018, it was reported that the Project Report
and the Environmental Document have been completed for the wildlife
crossing at Liberty Canyon (W of Liberty Canyon Road) over US 101, marking
a major milestone for the initiative. The project now moves into final
design and engineering (the “blueprints” phase) and is slated
to begin construction in late 2020. The planned wildlife crossing at
Liberty Canyon is a public/private partnership between Caltrans, the
National Park Service (NPS), the National Wildlife Federation (NWF), the
Santa Monica Mountains Conservancy, the Resource Conservation District of
the Santa Monica Mountains, the Mountains Recreation and Conservation
Authority, the California State Coastal Conservancy and The Santa Monica
Mountains Fund. The project responds to more than two decades of NPS
research on the conservation needs of LA’s mountain lions and
ecosystems and advances long-standing local efforts to establish habitat
connectivity for wildlife across US 101. A total of 8,859 comments were
received in response to the draft Environmental Document, with only 15
opposed. Additionally, California Department of Transportation gave
approval May 1 for the plan. The unpaved bridge across US 101 will feature
a natural landscape design to encourage mountain lions, bobcats and other
wildlife to safely cross the highway and expand their habitat from the
Simi Hills in the north to the Santa Monica Mountains and the Pacific
Ocean in the south. Construction costs will be paid through private
fundraising efforts led by the National Wildlife Federation. The group
hopes to raise $10 million in starter money by the end of 2018. No public
funds will be used. Caltrans chose the second of two proposals for the
bridge. Project Alternative 2 calls for the construction of a
165-foot-wide by 200-foot-long vegetated bridge across US 101 with an
extension over Agoura Road, a city street that runs parallel to the
freeway on the south side. The first alternative had no bridge over Agoura
Road.
(Source: BusinessWire, 5/3/2018; TOAcorn,

In August 2019, it was reported that the $87 million
bridge entered its final design phase in July 2019, and is on track for
groundbreaking within two years and completion by 2023, according to
engineer Sheik Moinuddin, project manager with the California Department
of Transportation. Construction will take place mostly at night and won't
require any lengthy shutdowns of the 101 freeway, officials said.
Moinuddin said Caltrans considers it a "special" project that the agency
hopes will inspire others like it across the state. One of the reasons
it's special is that 80% of the money to build it will come from private
sources. More than $13.5 in private funding has already been raised.
Officials are considering offering naming rights to the bridge if an
entity or individual - perhaps a Hollywood studio or star - ponies up a
significant donation. The remaining 20% will come from public funds
already allocated toward conservation projects, officials said.

In October 2020, it was reported that newly released
plans indicated that the Liberty Canyon Wildlife crossing, which will
eventually be the largest of its kind in the world, is scheduled to break
ground in 2021. The crossing is being built to give wildlife a way to
traverse US 101, and avoid being struck by any of the hundreds of
thousands of vehicles that pass through the area daily. The 165-foot-wide
crossing will stretch 10 feet over 10 lanes of US 101 at Liberty Canyon
Road, according to the National Wildlife Federation. Once it’s
built, the surface will be landscaped to help the structure blend into the
surrounding mountain habitat. The plans call for the top of the structure
to eventually be covered in nearly an acre of native vegetation so that it
can support wildlife and provide habitat, shelter, food and water that
different species need to survive. Living Habitats, which designed the
project, is collecting seeds, acorns and mushrooms that will be grown in a
special project nursery, and planted at the site to allow habitat to grow
vegetation naturally throughout the site from the soil up, according to
the National Wildlife Federation. Native oak and willow trees sourced from
the area will also be planted around the crossing, which will include
nearly nine acres of space along the two adjoining slopes of the
structure. The crossing, which previous reports said would cost $87
million to build, is a public-private partnership involving Caltrans, the
National Park Service, the Santa Monica Mountains Conservancy, Resource
Conservation District of the Santa Monica Mountains and the National
Wildlife Federation.

In January 2021, a presentation to the CTC gave an
update on this project. The project is estimated to cost $87 million, is
mainly privately funded, and represents an unprecedented partnership
between public agencies and private organizations including Caltrans, the
National Park Service, the Santa Monica Mountains Conservancy, the
Mountains Recreation & Conservation Authority, the Resource
Conservation District of the Santa Monica Mountains, and the National
Wildlife Federation. The project is currently funded through the majority
of design with a combination of conservation grants and private donations.
Pending efforts to secure remaining construction funding, the project is
anticipated to break ground in Fall 2021 and to be completed at the end of
2023 or early 2024.

In May 2021, it was reported that a record $25 million
conservation challenge grant from Wallis Annenberg and the Annenberg
Foundation to the National Wildlife Federation's #SaveLACougars campaign to build a wildlife crossing in the Los Angeles area will help
the project break ground later in 2021. The wildlife crossing at Liberty
Canyon over US 101 — which will be the largest wildlife crossing in
the world — will reconnect a long-fragmented ecosystem, a
biodiversity hotspot, and help protect the endangered mountain lion
population and other wildlife that make their home in the Santa Monica
Mountains. The wildlife crossing at Liberty Canyon is unprecedented in
many ways. It is the first urban crossing of its scale – spanning
210 feet over ten lanes of highway and pavement, along with an access road
– and is the first significantly funded through private donations
along with public support. The #SaveLACougars campaign to build the crossing will serve as a model for urban wildlife
conservation efforts across the globe. With this donation, the campaign
has raised over $44 million to date, and needs to secure an estimated $35
million to unlock the Annenberg Challenge Grant and to break ground in
November 2021.

In January 2022, the CTC approved for future
consideration of funding 07 – Los Angeles County. Liberty
Canyon Wildlife Habitat Connectivity Project. Construct a vegetated
bridge crossing and other
improvements on US 101. (MND) (EEM). The Project will construct a
vegetated bridge across US 101 in the City of Agoura Hills with the
crossing spanning the US 101 and Agoura Road at the Liberty Canyon Road
exit in Los Angeles County. The California Department of Transportation
(Caltrans) is the California Environmental Quality Act lead agency for the
Project. On April 12, 2018, Caltrans adopted the Mitigated Negative
Declaration for the Project and found that the Project would not have a
significant effect on the environment after mitigation. On December 17,
2021, Caltrans confirmed that the Mitigated Negative Declaration remains
valid and that there are no new identified impacts requiring mitigation.
Caltrans also confirmed that the preferred alternative set forth in the
final environmental document is consistent with the Project scope of work
programmed by the Commission.Stage 1 of the Project is estimated to cost
$60,500,000 and is fully funded through construction with Environmental
Enhancement and Mitigation Program Funds ($500,000), Wallis Annenberg and
Annenberg Foundation Funds ($25,000,000), California Wildlife Conservation
Board Funds ($25,000,000), Assembly Bill 128 Funds ($7,000,000), John
Logan Foundation Funds ($1,000,000), Corporate Donations ($1,000,000), and
Private Donors ($1,000,000). Construction is estimated to begin in Fiscal
Year 2022-23.

In April 2022, ground was broken for the wildlife
crossing. More than 5,000 individuals, foundations, agencies and
businesses from around the world contributed expertise and donations that,
as of Earth Day 2022, totaled more than $87 million — including a
$25-million challenge grant from Wallis Annenberg and the Annenberg
Foundation. Because the project spans an interstate, Caltrans will oversee
design and construction — but the transportation agency is not
providing funding. The 200-foot-long, 165-foot-wide bridge will be the
largest of its kind in the world. As envisioned by architects and
Caltrans, cougars will move — unseen by motorists — over a
reinforced concrete-and-steel crossing landscaped with irrigated native
vegetation, including oak and willow trees. Sound walls and light
deflectors will dampen the noise and headlights of the hundreds of
thousands of vehicles that pass through the area daily. Fencing up to 12
feet high would funnel wildlife including mountain lions, bobcats, deer,
coyotes, skunks, badgers, squirrels, mice and lizards over the passage. To
reduce roadkill, fencing would also extend several miles in both
directions from the project footprint. Completion is scheduled for 2025.

Palo Comado Canyon Interchange (approx LA 33.693)
In February 2012, it was reported that Caltrans and the City of Agoura Hills propose to construct
improvements at the US 101/Palo Comado Canyon Road interchange (PM
33.0/34.4), in Los Angeles County within in the City of Agoura Hills (this
is the "Chesboro Road" offramp). The project would include widening the
Palo Comado Canyon Road and Palo Comado Canyon Road Overcrossing over US 101 and modification of the interchange ramps in order to improve traffic
circulation, safety, and bicycle/pedestrian access. The need for this
project was first identified by Agoura Hills in their 1992 General Plan.
The Plan’s Circulation Element discusses the need for widening of
the US 101/Palo Comado Canyon Road overcrossing due to congested freeway
access and poor circulation. Discussion of the need for this project was
carried forth to the City’s 2010 General Plan. The Southern
California Association of Governments (SCAG) included the project in
Addendum #3 to their 2008 Regional Transportation Plan (RTP) and Draft
Amendment #08-34 to the 2008 Regional Transportation Improvement Program
(RTIP). The current (2012) overcrossing structure was built in 1963. It
provides two 12-foot lanes and 4-foot shoulders in each direction. A
5-foot sidewalk is provided on the west side of the overcrossing. The
minimum vertical clearance is 15.1 feet, which is located in the northeast
corner of the structure over the northbound US 101 number four lane. The
interchange is configured with tight diamond ramps on the northbound side
and hook ramps on the southbound side. The southbound hook ramps connect
with Dorothy Drive and Chesebro Road at a four-point intersection south of
US 101. A short section of Chesebro Road directly opposite the hook ramps
provides access from the ramps to Palo Comado Canyon Road. The southbound
off-ramp is a one-lane exit that widens to two lanes at its termini. The
southbound on-ramp is a one-lane ramp throughout. The northbound ramps
connect directly to Palo Comado Road. The northbound on-ramp has two lanes
starting from the Palo Comado Road intersection and tapers to a one-lane
on-ramp before joining the freeway. The northbound off-ramp begins as one
lane and widens to two lanes at its termini. The interchange does not
currently have any signalized intersections. The proposed new interchange
(as of January 2012) would include widening Palo Comado Canyon Road from
two to four lanes between Driver Avenue and Chesebro Road. Just north of
the overcrossing, Driver Avenue becomes Palo Comado Canyon Road; just
south of the overcrossing, Palo Comado Canyon Road becomes Chesebro Road.
The Palo Comado Canyon Road Overcrossing would be widened from one lane in
each direction to provide two lanes in each direction, along with a
dedicated left-hand turn lane, for a total of five striped lanes. A Class
II bike lane and sidewalks would be provided on both sides of the
overcrossing. The construction would maintain the existing layout of the
interchange ramps; however, the northbound on- and off-ramps would be
slightly re-configured, with an additional lane being provided on the
northbound off-ramp at the Palo Comado Canyon Road intersection. The
intersection of the northbound ramps and Palo Comado Road would be
signalized; the remaining intersections would remain un-signalized.
Details are found in the draft initial study. At an initial community meeting on the project, local residents expressed
concern about whether there was sufficient traffic to justify the changes.
In December 2012, it was reported that a feasibility study and environmental impact report have been done and public meetings held on proposed plans to widen Palo Comado between Driver Avenue and Chesebro Road. In response to these, the Agoura Hills City Council decided in November 2012 not to move forward with putting the engineering design phase of the project out to bid after 12 residents from the Old Agoura neighborhood spoke at the council's Nov. 14 meeting. They plan to revisit the issue in January 2013.
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $4,000,000 for High Priority Project #3099: Modify and reconfigure Kanan Road interchange (approx LA 35.029) along US 101 in Agoura Hills.
Reyes Adobe Bridge (approx LA 36.178)
In August 2008, it was announced that work would begin in October on the
demolition of the narrow Reyes Adobe Road bridge over Route 101, and its
replacement with a new overpass. The final $8.4 million package of
federal, state and regional transportation funds is being secured, and
officials expect the Agoura Hills City Council will approve going out to
bid on the project in September 2008. The project will replace a bridge
built in 1965 that has three lanes squeezed into space for two, no room
for bikes, and a sidewalk on only one side of the road. However, right of
way restrictions will prevent them from moving frontage roads a block away
from the freeway ramp intersections in a major circulation reconfiguration
(as was done at Kanan Road). As a result, the signal for Canwood Street on
the north side of the freeway will have to remain within a dozen yards of
the northbound half of the diamond interchange. The project will cost
$11.3 million, with most of that coming from impact fees paid by
developers to the city. About $3.9 million is coming from the federal
treasury under two special congressional appropriations, $2.1 million from
a grant from the Los Angeles County Metropolitan Transportation Authority,
and the rest from the city of Agoura Hills.

Lindero Canyon Bridge (approx LA 37.526)
In April 2013, it was reported that the new Lindero
Canyon Bridge will feature artwork from a Westlake Villiage artist. The
Westlake City Council in consultation with Caltrans, which is in charge of
the construction, commissioned sculptor Joe Wertheimer to design an
imprint for concrete on both sides of the bridge. Wertheimer, who works
out of a studio on Via Colinas in Westlake Village, said the project is
unique, as nobody has spanned a freeway. The original drawing of the scene
features mountains and trees as a backdrop to a lake with sailboats and
birds. This was then broken down into 1-inch scale,transferred to a 1-foot
scale. This was then drawn on each panel. During this process, the five
panels were lined up; the artist would sculpt one, two and three at a time
and then slide it down and add another panel, and that was the process for
eight months. The 42 panels were coated in plaster and used to make molds.
When completed, the work will be 360 feet long and 6 feet tall. It will be
created by pouring concrete into the form and then peeling off the front
molds to leave a raised relief. The $5 million project will add a traffic
lane in each direction, retrofit seismic upgrades and improve the
aesthetics of the interchange. The bridge project is being funded
primarily using Measure R funds from the Los Angeles County Metropolitan
Transportation Authority. Work is anticipated to begin in mid-June 2013,
and the project is expected to take about 10 months to complete, he said,
and once completed will help alleviate traffic backups at the intersection
during peak commuter hours. The upgraded bridge will feature an
11-foot-wide lighted pedestrian walkway on the east side. Each corner of
the bridge will be defined with a stone pilaster with a bronze sailboat
similar to the city’s entry monuments.

In May 2015, it was reported that the new Lindero
Canyon Bridge was open for traffic, providing two additional traffic
lanes, a protected bike and pedestrian path and decorative motifs
showcasing the Westlake Village lifestyle. The $7.5 million bridge and
interchange renovations are part of an overall program to improve local
roads and pedestrian pathways throughout Westlake Village. The
bridge’s center median was removed to provide an additional lane in
each direction, and an 11-foot-wide lighted pedestrian and cycling path
was added on the east side of the structure. Artist Joe Wertheimer
sculpting a 300-foot-long mural on the bridge’s exterior depicting a
scene of the city with its lake and hillsides. The bridge mural is the
first of its kind for a freeway bridge in the state.

In December 2015, it was reported that the American
Public Works Association recently recognized the City of Westlake
Village’s newly reconstructed Lindero Canyon Road Overpass with a
2015 APWA “Best” award in the transportation category for
cities under 50,000 in population. The new bridge features an additional
travel lane in each direction, an off-road pedestrian/bike path, seismic
upgrades, sustainable landscaping and a decorative mural. The mural,
sculpted by Joe Werthheimer, serves as a gateway to the city from the 101
Freeway.

Our Future 101 Project: HOV Lanes: Route 23/Thousand Oaks (approx VEN 0.684) to Route 33/Ventura
In January 2014, it was reported that Ventura County was beginning a study regarding
the possibility of adding toll (i.e., HOT or "express lanes") to US 101 in
Ventura County. But even if the Ventura County Transportation
Commission’s $111,000 feasibility study finds that installing
High-Occupancy Toll lanes along the 101 Freeway is doable, it would take
at least a decade before motorists could actually use them. The results of
the feasibility study should be available by the end of 2014, at which
time they will be discussed at a public VCTC meeting.
(Source: The Acorn)
In August 2017, it was reported that the wheels are
beginning to turn on a $750-million plan to add lanes to US 101 between
Thousand Oaks and Ventura, but construction could be over a decade away.
In July 2017, the Ventura County Transportation Commission formally
requested bids for preliminary engineering design and environmental
consulting services on the project, which would add a carpool, or HOV,
lane as well as auxiliary lanes to northbound and southbound US 101
between Route 23 and Route 33. Auxiliary lanes run between interchanges,
giving drivers more time to merge in or out. Most of the widening could be
done on land that’s already owned by Caltrans, said Darren Kettle,
executive director of VCTC, the regional transportation planning agency
that controls the use of government funds for the county’s
transportation projects. “I think we could shoehorn in a lane on the
inside and add auxiliary lanes on the outside,” Kettle said.
“Generally speaking, the project is not that complicated.”
Still, the roughly 28-mile-long effort comes with a hefty price tag: $750
million to $800 million, Kettle estimates. Some of the money will come
directly from the state, which two decades ago changed how local projects
are funded.
(Source: Simi Valley Acorn, 8/23/2017)
In April 2019, scoping meetings were announced to
obtain public input on this project. The plan is to add HOV lanes, and
potentially auxiliary lanes, along US 101 between Route 23 in Thousand
Oaks and Route 33 in Ventura.
(Source: District 7 Tweet, 4/18/2019)
In October 2022, the VCTC published the "Our Future 101" website, which provided more information on the project. Although much of the site, at this time, is high-level and
nebulous, it does note that the Project Development Team has chosen three
Alternatives to move into the next step. These alternatives are: Alternative
1 – No Build; Alternative 2 – Add an HOV/Express
Bus Lane in each direction; Alternative 3 – Add an
HOV/Express Bus Lane in each direction, with design variations In general,
the alternatives were structured to gain the greatest improvement in
traffic conditions and safety levels relative to the costs involved. It
also notes that while adding a general purpose lane was not one of the
alternatives included in the early planning phase, a general purpose lane
alternative was evaluated in the alternatives analysis phase. The
width of a general purpose lane alternative is similar to the width of
Alternatives 2 and 3, and as such, the physical impacts and cost of a
general purpose lane alternative is similar to Alternatives 2 and 3, a
general purpose lane does not move as many people as quickly or reliably
as an HOV lane alternative. For those reasons it was eliminated from
further consideration. It noted that early planning phase construction
cost estimates range from $575 million to $2 billion depending on the
alternative.These cost estimates will be refined as the project
progresses. VCTC is currently estimating that construction will be
complete by 2040. If full funding is available sooner, then construction
will start sooner. The actual construction period can only be determined
once the construction funding plan is determined.

Route 23/US 101 Interchange Improvements (approx VEN 3.155)
In May 2009, using money from the ARRA (Stimulus Package), Ventura County commissioners agreed to give $6.5 million to Thousand Oaks to begin the design process for the widening of the interchange of US 101 and Route 23. The Thousand Oaks City Council recently decided to loan the project money from the city's General Fund so the process could begin this year and to reimburse the General Fund when (if?) the state funding comes through in 2010-11. In late July 2009, the city reached a cooperative agreement with the California Department of Transportation to take over the design. The proposed improvements will add one lane on US 101 in each direction between the Los Angeles/Ventura County line and Moorpark Road by widening the freeway, restriping, reconstructing the median, and realigning a portion of the center line. Soundwalls will be constructed between Hampshire Road and Conejo School Road on the northbound side and between Manzanita Lane and Hampshire Road on the southbound side. The city hopes that the design process will be completed by May 2012 at the latest and that Caltrans will be able to take back the project at that point to begin the construction process. However, the construction phase is still unfunded at this point and additional federal funds will be required to complete the work by 2016 as laid out in the preliminary schedule.
In late September 2011, it was reported that the Thousand Oaks City Council on Tuesday considered loaning $20 million out of city reserves to cover the pending CTC portion of the funding. The city's loan would be contingent on the state transportation commission agreeing to pay it back using the money the panel planned to award the project in 2016. If an agreement between the city and state is reached, the $20 million would be used as required matching funds for a federal transportation stimulus grant. Thousand Oaks and VCTC plan to jointly apply for a $20 million grant in October. The grant requires a minimum 20 percent local match. Construction could get under way in late 2012 or early 2013. It would add a new lane on US 101 in each direction and two lanes on the ramps that narrow to one lane would be extended. Design work on the interchange is expected to be completed early next year. The work, which includes rights of way for utility relocation, cost $6 million and was funded with federal stimulus money.
In January 2012, it was reported that the City of Thousand Oaks lost out on $19.5 million in funding it was seeking through the U.S. Department of Transportation's TIGER III grant program. This is anticipated to delay the start of construction for several years, unless funding is obtained in the 2012 transportation bills. In March 2012, officials from the Ventura County Transportation Commission and the City of Thousand Oaks traveled to Washington, D.C., ahead of the March 19 deadline to reapply for a $20-million Transportation Investment Generating Economic Recovery (TIGER) grant. If the city’s request is approved, construction would start in early 2013 and finish in about two years.
In October 2012, it was reported that the Thousand Oaks City Council voted unanimously Oct. 9, 2012 to advance up to $17.7 million from its capital fund reserves to jump-start the estimated $42-million US 101/Route 23 interchange project, pending the granting of anticipated state and federal funds. Even with the council’s approval of the loan, work can’t begin until the state agrees to the arrangement. City and county officials have been trying unsuccessfully for years to obtain state and federal funds to pay for the interchange expansion, which would add a travel lane in each direction for drivers connecting to US 101 from Route 23 or vice versa. Thousand Oaks and VCTC tried twice before to obtain a $20-million federal Transportation Investment Generating Economic Recovery (TIGER) grant. Both applications were denied. Also in October, the California Transportation Commission unanimously approved the use of $11.9 million to partially fund the $42 million project. The $11.9 million is money left over from the widening of the US 101/Rice Avenue interchange project in Oxnard. It comes from funds that must be used to aid the movement of freight. The project will add one lane in each direction of Highway 101 between the Ventura County/Los Angeles County line and Moorpark Road. Sound walls will also be built.
On March 1, 2013, the Ventura County Transportation
Commission, a body representing all 10 cities in the county, approved a
critical loan repayment agreement between the City of Thousand Oaks and
the state that could get the long-awaited construction effort underway by
the end of 2013. The project, which is estimated to cost $42 million,
would add a travel lane in each direction for drivers connecting to US 101
from Route 23 and vice versa. It’s been discussed for more than a
decade but the county has been unsuccessful up until now in finding the
funds to pay for it. Under the agreement, Thousand Oaks will put up $15.7
million to get the work started, money that would be repaid by 2016 from
the state’s Transportation Improvement Program. The Thousand Oaks
City Council voted unanimously in November 2012 to advance the money from
its capital fund reserves before millions in state funding becomes
available.

In December 2013, it was reported that Caltrans planned to award the construction contract in January 2014. The roadwork will add a travel lane in each direction for drivers connecting to US 101 from Route 23 and vice versa. Sound walls will be constructed on the north side of the interchange between Hampshire and Conejo School roads and on the south side between Manzanita Lane and Hampshire. Caltrans plans to award the construction contract to Security Paving Co, Inc. of Sylmar, which submitted a $24.7-million bid in September.
In January 2013, the CTC approved an AB 3090 cash reimbursement in order to use local funds to replace $20,000,000 in fiscal year (FY) 2015-16 Regional Improvement Program (RIP) funds for construction of the Los Angeles County Line to Route 23 – US 101 Improvements - Phase 1 project (PPNO 2291). The City and VCTC propose reimbursement of $15,764,000 in FY 2015-16, with the remaining $4,236,000 returning to Ventura County’s share balance. This project will improve Route 101 from the Los Angeles County line to Moorpark Road, including improvements to the interchange of Route 101 and Route 23.
In December 2015, it was reported that a decision to
redesign a sound wall along US 101 in Thousand Oaks could push back the
scheduled completion date of the US 101/Route 23 interchange expansion by
weeks, if not months. Started in February 2014, work to expand the
juncture of two of Ventura County’s busiest freeways was originally
expected to last around two years. Now it’s looking more like
two-and-a-half. The original plan was to save the existing retaining
walls; but once excavation began, that proved to be significantly
expensive because of the grading difference. The adjustments, approved by
the Thousand Oaks City Council, are waiting for the go ahead from the
Ventura County Transportation Commission and CalTrans before they can take
place, an approval process that could take weeks or months. The sound wall
in question is on the south side of US 101 along southbound Hampshire
Road. The wall is being moved to provide the greatest possible reduction
in freeway noise to a nearby residential area on Willow Lane, according to
city report. This change saw the total cost of the expansion, now in its
21st month, swell from $33.6 million to $37.5 million, a
difference of nearly $4 million.
(Source: TO Acorn, 12/3/2015)
In February 2016, it was reported that the City of
Thousand Oaks was asking Caltrans to make good on its promise to plant new
trees in the place of those removed during the expansion of the US 101 -
Route 23 interchange. The state agency had planned to hold off on the
proposed planting work until after drought conditions improve and the use
of potable water is no longer restricted for landscape purposes. Thousand
Oaks noted that the project Environmental Document identified the tree
removal as a biological impact that required mitigation through
installation of replacement trees based on the standards of the City of
Thousand Oaks Oak Tree Ordinance. Caltrans removed at least 16 mature oak
trees in accordance with project plans—and may have removed even
more. No timeline for when the replacement landscaping will be planted was
offered. As part of its 2015 Drought Action Plan, the state’s
transportation department has been evaluating all plantings that are
irrigated with potable water, including those that were promised as a
condition of project approval.

In April 2016, it was reported that construction on the
US 101/Route 23 freeway interchange in Thousand Oaks, originally slated to
finish in spring 2016, was now expected to end in August. The Caltrans-led
expansion of the county’s busiest interchange is in its 26th
month. Work was delayed in late 2015 when engineers discovered a soundwall
intended for the south side of US 101 near Hampshire Road could not be
built as originally designed. The soundwall redesign increased the
anticipated cost of the expansion from $33.6 million to $37.5 million in
December, forcing the cash-strapped state agency to come up with an
additional $4 million. The taxpayers of Thousand Oaks are still waiting to
be paid back for the project by Caltrans and the Ventura County
Transportation Commission. So far, the city has somewhere between $11
million and $12 million invested, or roughly 37 percent of the total
expense.
(Source: Moorpark Acorn, 4/15/2016)
In June 2016, it was noted that the completion date had
been pushed to the fall. Ramp metering system installation and drainage
and irrigation work are nearing completion. About 50 percent of remaining
soundwall and retaining wall construction has been completed. Over the
next few months, construction activities will include profile grinding,
striping work and landscaping. In response to area residents’ safety
concerns, Caltrans has examined the Moorpark Road northbound on-ramp and
will be adding signage and a ramp meter, which will help control the flow
of traffic entering the freeway and also ease some of the merging issues
drivers are facing.

In October 2016, it was reported that Ventura
County’s largest freeway undertaking in recent history is finally
coming to an end after 32 months of construction. Caltrans, along with the
City of Thousand Oaks and Ventura County Transportation Commission, hosted
a dedication ceremony Nov. 1, 2016 to mark the completion of the US 101-Route 23 Interchange Improvement Project, a nearly $40-million effort
to ease congestion at one of the region’s most notorious
bottlenecks. The endeavor involved adding a travel lane in each direction
for drivers connecting to US 101 from Route 23, re-striping off-ramps and
interchange lanes from one lane to two, and constructing sound-walls on
both sides of US 101. Among the final items crossed off the
project’s checklist: completion of a soundwall on the southbound
side of US 101 at Hampshire Road that needed to be redesigned
mid-construction and the re-striping of sections of northbound US 101 to
help ease confusion regarding exit-only lanes.

In January 2012, construction will begin on improvements to the Wendy Drive interchange (approx VEN 7.884). This is based on the fact that in August 2011, the city of Thousand Oaks secured $10.7 million in federal money for the $13.5 million, 18-month project to widen northbound and southbound ramps. The rest of the funding consists of $605,000 in gas tax money and $2.9 million in developer fees, although it will be several years before the city receives the developer money. Plans to alleviate congestion at the interchange include adding a travel lane in each direction on the bridge,adding a lane on the westbound on-ramp and the eastbound off-ramp, as well as updating signals, planting landscaping, adding decorative railing and light fixtures on the bridge, and installing a northbound bike lane on Wendy. The bike lane will run between two vehicle lanes to keep cyclists from riding past cars coming on or off the freeway that are not required to stop. This design is the first of its kind and has garnered the support of cyclists and Caltrans. Along with temporary ramp closures, the entire freeway in both directions will be shut down for several nights to install steel girders across the highway. The first full closure will come nine months into construction, with a second full closure at the one-year mark. Traffic will be detoured onto local streets. One lane on the bridge also will be closed during construction to allow for the span's widening. In early December 2011, the Thousand Oaks City Council awarded a $1.2 million construction management contract to AECOM Technical Services, Inc. of Los Angeles and a $8.4 million construction contract to Valencia-based C.A. Rasmussen, Inc. The construction bid came in $1.1 million less than the city's estimate. Updates on the project may be found on a website maintained by the City of Thousand Oaks.
In May 2005, the CTC considered relinquishment of right of way in the City of Camarillo, on Petit Street, 0.1 mile west of Calleguas Creek, consisting of frontage roads (7-Ven-101-PM 12.9).
In February 2009, the CTC approved relinquishment of right of way in the city of Camarillo along Route 101 from Route 34 (Lewis Road) to Arneill Road, consisting of relocated or reconstructed city streets, frontage roads, and parking facilities (7-Ven-101-PM 13.8/14.2).
In January 2018, the CTC authorized relinquishment of right of way in the
city of Camarillo along Route 101 on Ventura Boulevard and Carmen Drive
(07-Ven-101-PM 14.7/15.1), consisting of collateral facilities. The City,
by freeway agreement dated February 12, 1997, agreed to accept title upon
relinquishment by the State. The 90-day notice period expired December 6,
2017.

There are plans to construct a new interchange at Springville Drive in Camarillo, CA (approx VEN 16.787). According to the Ventura County Star in December 2009, the Camarillo City Council finally agreed to move forward with a new US 101 interchange project near Springville Road. The council voted unanimously to establish a “benefit area” to raise money for the $51 million Springville Interchange project. About $23 million is needed for a new bridge, on- and off-ramps and road extensions, said City Manager Jerry Bankston. The rest is for additional improvements in the Springville and north Camarillo Airport areas. Property owners in the benefit area will pay one-time road and bridge improvement fees to the city, which will sell bonds to finance the interchange up-front. The council also approved the formation of a Community Facilities District within the benefit area. The district would include 47 acres owned by Robert D. Selleck of Selleck Properties. “Without the district, we could not have raised the (bridge fee) money, especially under these tough economic times,” Selleck said. Mayor Kevin Kildee said the interchange is necessary to improve traffic flow throughout the city, especially with the recent expansion of Camarillo Premium Outlets and future growth at CSU Channel Islands. The project will include an interchange with a six-lane bridge over the freeway, new on- and off-ramps and a connection to an extended Verdulera Street. Ponderosa Drive will be widened to four lanes from Las Posas Road to the new interchange. Ventura Boulevard will also be extended east and west of Springville. The California Department of Transportation has approved permits for the project, and the city plans to start construction at the beginning of 2010.
Rice Avenue Interchange (approx VEN 20.073)
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $2,640,000 for High Priority Project #1565: Interchange improvements at Rice Avenue and US 101 in the City of Oxnard (approx VEN 20.073).
In February 2009, the CTC approved for future consideration of funding a project in Ventura County to reconstruct the interchange at Route 101 and Rice Avenue and improve traffic operations, enhance safety and increase capacity. The project is programmed in the Trade Corridor Improvement Fund (TCIF) and includes local funds and federal demonstration funds. The total estimated project cost is $86,899,000. It is estimated to begin construction in Fiscal Year 2008-09. The scope as described for the preferred alternative is consistent with the project scope set forth in the approved project TCIF baseline agreement. In May 2009, the Ventura County Transportation Commission approved the allocation of $5 million for improvements to the Rice Road-US 101 interchange in Oxnard, using regional ARRA funds. The project is expected to be completed in middle 2012. In February 2012, the CTC adjusted the project funding to reflect construction savings.
In October 2013, the CTC relinquished right of way in the city of Oxnard adjacent to Route 1 and US 101 on Wagon Wheel Road, consisting of collateral facilities (07-Ven-1-PM 21.0, 05-Ven-101-PM 22.5/R23.0).
In March 2016, the CTC allocated additional funding for a project on Route 101 in Ventura County in the cities of Oxnard and Ventura, from Route 232 to Montalvo Spur Overhead (roughly Vineyard to N of the Santa Clara River, approx VEN 21.985 to VEN R24.637) that will widen the roadway and bridges along this route.
In Ventura, the current 5-lane bridge (3 lanes EB, 2 lanes WB) over the
Santa Clara River (approx VEN R23.291) will be replaced with a new 12 lane
bridge. The current Route 1 flyover that currently brings that traffic
into the left-lane lane of US 101 will become a right-lane entrance that
is standard. This is TCRP Project #47. In October 2006, the city of
Ventura requested additional funding for environmental documentation. The
goal of the Route 101, California Street Off-Ramp project is to improve
the traffic flow, sight distance, and increase ramp storage to mitigate an
existing problem of traffic backing up to the freeway. The project also
creates a connection between California Street and the downtown business
district. The project is projected to be completed in FY 2009/2010,
although according to the Los Angeles Times, the widening should be
completed in mid August 2007. Work began in 2002 and was to be completed
in four years. Problems and design revisions delayed the project and
pushed construction costs from $72 million to $85 million. The project was
constructed by Sacramento-based MCM Construction Inc., a leading bridge
builder in California who has erected spans over Malibu Lagoon on Pacific
Coast Highway, built the Riverside Freeway (Route 91) and I-5 interchange
near Knott's Berry Farm and installed bridges across I-210 between Fontana
and San Dimas. The project was subject to numerous restrictions. Between
Dec. 15 and June 1, crews couldn't use heavy equipment in the streambed.
Wildlife authorities imposed the restriction to protect a rare songbird
that, despite the nearby traffic and development, nests in the willows and
alders along the river. The presence of the imperiled southern steelhead
trout, which migrates up the river in winter months, hampered progress on
the bridge. In 2004, the heaviest rainfall in Southern California in over
100 years swept away the project's scaffolding and support equipment.
Average daily traffic flows are forecast to reach 214,000 trips daily
while peak traffic flows are expected to reach 18,000 vehicles per hour by
2025, according to Caltrans and the county Transportation Commission. In
September 2011, the CTC received a request to update the project schedule
and funding plan and to re-allocate $120,000 in previously allocated TCRP
funds. This project originally included $606,000 in TCRP funds for the
Environmental (PA&ED) phase. In October 2006, the Commission approved
an additional allocation of $120,000 for environmental work. The project
was subsequently suspended after several technical issues with drainage
and storm water runoff were revealed. Now that a solution to the issues
has been identified, the City would like to proceed with completion of the
environmental work. The previously allocated $120,000 in TCRP funds is
currently unexpended and set to expire in October 2011. The City requests
that these funds be reallocated so the project can move forward. The City
also requests that the funding plan be updated to reflect the addition of
$2,750,000 in Congestion Mitigation and Air Quality (CMAQ) funds for the
project.
Mussel Shoals to Casitas Pass Road Widening/HOV (PM VEN 39.8 to SB 2.2)
In 2007, the CTC recommended funding (from the Corridor
Mobility Improvement Account [CMIA]) to construct HOV lanes from Mussel
Shoals to Casitas Pass Rd ($151,470K requested; $131,600K recommended). In
March 2009, the CTC approved for future consideration of funding a project
spanning Ventura and Santa Barbara Counties to construct HOV lanes in each
direction and roadway improvements near the community of Mussel Shoals in
Ventura County to Casitas Pass Road in Santa Barbara County. The project
is programmed in the Corridor Mobility Improvement Account (CMIA) and the
2008 State Transportation Improvement Program (STIP). Total estimated cost
is $151,470,000. Construction is estimated to begin in Fiscal Year
2010-11. Specifically, six miles of car-pool lanes will be added, and the
project shuld begin in winter 2011. In November 2010, it was noted that
the project will also include a bike path that is separate from the
highway lanes, a new walkway under the highway between La Conchita and the
beach, and the closing of the left turn lanes in and out of La Conchita
and Mussel Shoals. Caltrans officials say they would have preferred the
bike path to be on the mountain side, but the California Coastal
Commission asked them to move it because it wants to encourage development
of a network of coastal trails that stretch from Oregon to the Mexican
border. Putting the bike lanes on the southbound side means a smaller
shoulder on that side of the road — 10 feet, down from 19 feet now
— which means there won't be room for surfers, fishermen and
beachgoers to park their cars. The southbound shoulder near La Conchita is
designated now as emergency parking only, but the rule is rarely enforced.
Caltrans is also including sound walls at the request of Mussel Shoals
homeowners. The agency asked people living in all of the small communities
along US 101 whether they wanted sound walls, and Mussel Shoals was the
only community that voted for them. The walls will be from 8 to 14 feet
tall. In November 2010, it was reported that there was some opposition to
the plan—less due to the widening than the location of the bicycle
path on the ocean side of the roadway. They claim that that location would
reduce access, be vulnerable to erosion and create parking problems.
However, the Coastal Commission sided with Caltrans and kept the bike lane
where it was.
(Source: VC Star, 10/26/2010)
Environmental and design studies are underway to add extra capacity to the clogged corridor along a six mile stretch between the Mobil Pier and Casitas Pass Road. The general idea is to add a carpool lane in both directions using the existing median area. In addition to the extra lane, shoulder and median widths may be enlarged. In addition, the non-freeway portions in La Conchita and Mussel Shoals would be converted to full freeway standard and the left and u-turn openings closed off. Operational improvements include the addition of traffic cameras, pavement speed sensors and changeable message signs. Proper sound walls and retaining walls would be built as well as metal guardrail replaced with concrete barriers. In July 2010, the Ventura County Planning Commission voted unanimously to grant a permit for the project and funding has been obtained through $150 million in transportation bonds. Construction could begin in late 2011.
In August 2011, the CTC approved schedule and funding changes to the HOV lane project near Mussel Shoals. The project was delayed due to a number of issues, including (a) Coastal Zone permitting requirements – Considerable coordination with the California Coastal Commission (CCC) was necessary in order to obtain coastal development permits for the project. This delayed the design phase by over a year. (b) Right of Way (R/W) easement requirements – The proposed pedestrian undercrossing at La Conchita passes through Union Pacific Railroad (UPRR) R/W. Easements required for the undercrossing were declined by the UPRR and the Department began the condemnation process. A Resolution of Necessity was approved at the June 2011 Commission meeting. Negotiations for the compensation of the easement with UPRR are on-going. These changes move the start of construction out a year to February 2012, with construction completion scheduled for August 2016.
In August 2011, the CTC approved $131,600,000 in state-administered CMIA funds for construction of HOV lanes on US 101 from near Mussel Shoals, in Ventura County to just south of Casitas Pass Road in Santa Barbara County. In March 2012, the CTC reduced the original CMIA allocation for construction on Route 101 by $50,307,000, from $116,300,000 to $65,993,000, for the HOV Lanes, Mussel Shoals to Casitas Pass Road project (PPNO 3918) in Ventura and Santa Barbara Counties.
In May 2012, ground was broken for the first HOV lanes on US 101 in Southern California, expected to be completed in late 2015. These go in both directions from Mobil Pier Road in Ventura County to Casitas Pass Road in Santa Barbara County. Most of the $102 million project is in Ventura County, with a small portion in Santa Barbara County. The project also will include a southbound bike path and a pedestrian undercrossing in La Conchita. After the project is finished, ground will be broken in 2016 for a carpool lane along Highway 101, from Carpinteria to Santa Barbara.
In January 2016, the CTC approved $59,486,000 for a Proposition 1B - State Administered Multi-Funded TFA/STIP Project on US 101 related to the Casitas Pass & Linden Avenue Interchanges. In Carpinteria, from Carpinteria Creek Bridge to Linden Avenue. Reconstruct two interchanges (Casitas Pass Road and Linden Avenue) and extend Via Real Frontage Road. Future Consideration of Funding approved under Resolution E-10-90; November 2010.
In May 2016, it was reported that the California
Transportation Foundation named a project that constructed bicycle lanes
next to US 101 between Ventura and Santa Barbara counties as the Bicycle
Pedestrian Project of the Year at its annual awards luncheon in
Sacramento. The project, dedicated by the state Assembly as the Ralph
Fertig Memorial Bike Path, was a joint effort between the Santa Barbara
County Association of Governments, Caltrans and the Ventura County
Transportation Commission. The new path provides a route of travel that's
separated from but adjacent to US 101 and on the ocean side of the
freeway. The old bike route forced cyclists between parked cars and
freeway travel lanes along the Rincon area of US 101. See-through railing
on the new path was designed to preserve views of the ocean while
protecting users from the freeway traffic. Granite Construction was the
contractor and MNS Engineers Inc. was construction manager. Construction
funding was awarded by the California Transportation Commission with
voter-approved Proposition 1B funds. It was constructed along with a US 101 widening project and in completed in 2015.

In April 2019, it was reported that one of the conditions for the Casistas
Pass and Lincoln Avenue Interchanges was construction of the
much-anticipated Rincon Multi-Use Trail that will connect the city of
Carpinteria to Rincon County Park. The new community asset is scheduled
for completion before the end of 2020 as a condition of the Caltrans
Linden-Casitas Interchange Project. City permitting for the project to
widen and improve the freeway through Carpinteria included improving
coastal access for cyclists and pedestrians. The route will begin at the
intersection of Route150 and Carpinteria Avenue, descending from the
bluffs over CalTrans property near the freeway corridor before veering
toward the ocean, across a newly constructed bridge over the Union Pacific
Railroad tracks and end in Santa Barbara County’s Rincon Park. The
new segment of trail will also be a connector with the Carpinteria Coastal
Vista Trail from the Carpinteria Bluffs. Upon completion of other
segments, the Coastal Vista Trail will provide contiguous pathways from
Santa Claus Lane to Rincon Point. The trail completion timeline was
initially aligned with Linden-Casitas Interchange Project completion.
However, that project will be completed ahead of schedule this year, and
the Rincon Multi-Use Trail remains on track for the originally scheduled
2020 completion. As part of the new MOU, SBCAG allocated $250,000 for
updated environmental studies and design work from the Regional Surface
Transportation Program.

In January 2020, it was reported that the 7- mile
stretch of the US 101 between Carpinteria and Summerland (Linden and
Casitas Pass project) should be open in late March 2020. The widening on
the southbound lanes will be followed by the northbound lanes with
completion in 2022 and 2023.

In March 2020, it was reported that crews are on track
to complete the overpasses and Linden Avenue roundabout in late
spring/early summer of this year, according project spokesperson Kirsten
Ayars. The completion date for the project was initially accelerated, but
the Thomas Fire and subsequent debris flow had an impact, including the
time-consuming task of removing sediment that lodged in the utility
pathways through the new Carpinteria Creek bridge, Ayars added. Moving
forward, Ayars pointed to the upcoming US 101 widening from Bailard Avenue
to the city limits of Carpinteria at the western edge of the Salt Marsh,
slated to begin in April and continue into 2023. Concurrent highway
widening work will take place in Summerland, followed by a Padaro Lane
segment, for an eventual three-lane highway running from Bailard Avenue in
Carpinteria to Sheffield Drive in Montecito in approximately three
years’ time. Ayers noted that landscaping work has been scheduled to
occur as the added lanes are being built, which she said is a significant
time saving element to the overall project.

In November 2021, it was reported that community
members have been protesting the revised Rincon multi-use trail project.
The project has been a subject of public discussion over the past several
years, after first appearing on the county and city’s desk nearly a
decade ago. Its 2,800 linear feet stretches across county, city and
CalTrans property, at 16-feet wide – all concrete – and with
protective fencing and railings. Of the proposed trail, 850 feet is under
Carpinteria’s jurisdiction. The goal of the project, as expressed by
city officials over the past several years, is to improve bicycle and
pedestrian safety and to prevent people from crossing the railroads
tracks, which is illegal. It also would offer cyclists another route down
the coast, other than the shoulder of US 101—which is legal, but
unsafe. The current version of the trail offers a similar alignment
to its predecessor that was originally found “technically unfeasible
to build”; the current design changes where and how the trail would
cross the railroad. Current projections show an average of 70,000 uses of
the trail a year. The trail would start from Carpinteria Avenue just east
of the intersection with Route 150 and proceed east about 2,800 feet,
terminating at the west end of the Rincon Beach parking lot. It would be
about 16 feet wide with a “travel lane” in each direction and
3-foot shoulders on each side, and include a 6-foot-wide shallow concrete
ditch along the inside of the trail to capture and convert stormwater to
onsite drainage facilities, protective fencing along the trail, and a new
14-foot-wide clear-span pre-fabricated bridge crossing over the Union
Pacific Railroad alignment, according to the staff report.The controversy
for the project lies in its plan to potentially destroy a launch site,
prominently used by paragliders and hang gliders. After lengthy public
comment and discussion, the board unanimously voted to move the project
forward to the Carpinteria Planning Commission. The project is
budgeted at $12 million, with funding coming from federal and state
transportation dollars, according to Matt Roberts, Carpinteria Parks and
Recreation public facilities director. However, some aspects of the
funding still need to be identified. The anticipated start of
construction is in 2023, but the project still needs to get coastal
development permits from the City of Carpinteria and Santa Barbara County.

In January 2022, it was reported that the Carpinteria
Planning Commission passed the Rincon Trail Project at its 1/18/22
meeting, choosing from four proposals an option that was not favored by
the soaring community – who showed up strong to the public hearing
to voice concern for the future of their launching point on the bluffs,
“Little Diamondhead.” Despite the pushback from the glider
pilots, and some similar questions from Commissioner John Callender about
the decision-making process, the Environmental Impact Report (EIR) was
certified and the planning commission accepted Alternative 3, the proposal
option preferred by a majority of city staff. The motion was passed in a
3-1 vote, with commissioner Callender opposed. Though the report offered
four alternatives for the planning commissioners to choose from, the
choice ultimately came between Alternative 3 and Alternative 4, with the
soaring community at the center of discussion. Alternative 3 would require
the least amount of “earthwork,” city staff said, and
Alternative 4 could pose some problems with rerouting walkers and hikers
in order to avoid the gliders’ fly-zone. Choosing the option that
would appease the soaring community would also detract from one of the
path’s main purposes – providing a scenic trail to enjoy the
coast’s unique terrain. Along with certifying the EIR, the approval
checks all the boxes for the project to move forward with conditional use
and coastal development permits to start on the 850-foot stretch of trail
between the city and Rincon Beach Park. The rest of the multi-use trail
lies in Santa Barbara County, which is slated to begin as soon as the
project is passed by Carpinteria City Council.

In May 2023, it was reported that the Carpinteria City
Council ruled 3-1 to pursue alternative three – an altered version
of the proposed Rincon Multi-Use Trail project that sparked controversy
for impacts to paragliding and safety concerns – during a special
meeting. The Rincon Multi-Use Trail Project was originally conceived
as a solution to the current gap between the Pacific Coast Bikeway and the
Carpinteria bluffs in the California Coastal Trail. The project gained
controversy, however, following the Planning Commission’s Jan. 18,
2022 approval of the project’s environmental impact report and
Conditional Use Permit and Coastal Development Permit. The completion of
this project is mandatory for the city of Carpinteria to be in accordance
with its Coastal Land Use Plan and the conditions of approval for the
Caltrans Casitas Pass and Linden Avenue project. The original
environmental impact report outlined four alternatives for the project to
take, and said that the third option, the “steeper slopes / reduced
earthwork alternative” – has the least significant
environmental impact.

In his 2006 Strategic Growth Plan, Governor Schwartzenegger proposed widening US 101 in Santa Barbara and Ventura County.
In 2007, the following requests for funding from the Corridor Mobility Improvement Account (CMIA) were made, but not recommended for funding: widening and adding Intelligent Traffic Systems from Milpas to Cabrillo Hot Springs in Santa Barbara County ($28,613K requested); and the addition of HOV lanes from Casitas Pass Rd to Milpas St in Santa Barbara County ($12,600K requested).
HOV Lanes / Carpenteria to Santa Barbara (approx SB 1.623 to SB 12.755)
In July 2008, work began on a series of projects to improve the flow of US 101 in Santa Barbara. This includes a $53 million
project to widen the freeway between Montecito and Santa Barbara. As of
August, the extent of the work had included the removal of trees and
bushes along the roadway, restriping some of the lanes and putting in
concrete barriers. The speed limit has also been reduced along the route
to 55 mph. The two lanes will remain open during the day, but at night,
when construction is being done, the highway will be reduced to one lane
each way. The more significant work of widening US 101 all the way to the
Ventura County line depends on voters' in Santa Barbara County approving a
renewal of a transportation sales tax in November. Voters rejected the
renewal once before. Ventura County voters have twice rejected a similar
measure, but local officials are mulling over a third try in the coming
years. In three years there are plans to begin widening the highway from
Mussel Shoals, past La Conchita and north past the Rincon. But before that
begins, there will likely be several phases of construction in Santa
Barbara County. The first phase would add a lane in both directions
between Milpas Street in Santa Barbara south to Montecito's Hot Springs
Road.

In June 2009, the CTC recieved notice of the preparation of a draft EIR. The project under consideration would construct a new HOV lane on Route 101 between Bailard Avenue in the city of Carpinteria and Milpas Street in the city of Santa Barbara. The project is not fully funded. The project is programmed in the 2008 State Transportation Improvement Program (STIP) for Plans, Specifications, and Estimates in the amount of $12,585,000. Santa Barbara County voters, through the passage of Measure A in November 2008, dedicated $140,000,000 of regional sales tax funds toward the construction of this project. The total cost of the project is estimated to be between $380 million and $600 million. Assuming the availability of funding, construction is estimated to begin in Fiscal Year 2013-14. In addition to the no build alternatives, there are three alternatives under consideration. All build alternatives propose to add one HOV lane in each direction, resulting in a six-lane freeway within the project limits. Alternative 1 proposes to add the HOV lane while balancing outside and inside (median) landscaping impacts. Alternative 2 proposes to add the HOV lanes while maximizing the amount of median planting within the project limits. Alternative 3 proposes to add the HOV lanes within the existing median with minor incidental outside widening.
In March 2011, the CTC received notice of an amendment that proposes to extend the limits of this project to the south by 0.6 mile. This would change the southern project limits from 0.4 mile south of Carpenteria Creek Bridge to 0.2 mile south of Bailard Avenue. The proposed change would incorporate improvements to storm water treatment facilities at the Bailard Avenue interchange.
In April 2012, Caltrans released the draft EIR for the project. The project involves an 11-mile stretch of freeway, and would add HOV lanes between Sycamore Creek, north of
Salinas Street, in Santa Barbara and Bailard Avenue in Carpinteria. During
peak traffic periods, the extra lanes would be restricted to vehicles with
two or more passengers. The HOV lanes would be open to all vehicles
outside of the morning and afternoon commute times. The project also would
have “substantial adverse visual impacts” and require
amendments to the local coastal plans for the cities of Santa Barbara and
Carpinteria, due to the proximity of several wetlands locations. Three
build alternatives—Alternatives 1, 2, and 3—and a No-Build
Alternative are proposed for this project. Alternative 1 proposes to widen
to the median in some locations and widen to the outside in other
locations to balance inside and outside resources. Alternative 2 proposes
widening to the outside to maximize available areas for median
landscaping. Alternative 3 proposes widening to the inside, which means
building all new paved lanes within the existing available median. All
build alternatives would be built mainly within the existing public
right-of-way with only slight variations between all three. Projected
costs for each build alternative vary and depend on which configuration is
selected for the Cabrillo Boulevard Interchange. Current proposed costs
for the alternatives with the various Cabrillo Boulevard Interchange
configurations are: Alternative 1 ranges from $285 million to $340
million; Alternative 2 ranges from $305 million to $355 million; and
Alternative 3 ranges from $270 million to $325 million. All of the
alternatives will widen the freeway to provide for a six-lane facility
within the project limits, and will add a part-time, continuous access HOV
lane in each direction on US 101 extending from Carpinteria Creek in the
City of Carpinteria to Cabrillo Boulevard in the City of Santa Barbara.
They would also (a) improve the southbound shoulder ditches near the
Bailard Avenue interchange to provide graded, flat-bottom swales to be
used for stormwater treatment, (b) replace bridge structures at Arroyo
Paredon (Parida), Toro Canyon, Romero (Picay), Oak, and San Ysidro creeks,
(c) widen bridge structures at Franklin and Santa Monica creeks, (d) widen
traffic undercrossing structures at South Padaro Lane and Evans Avenue,
(e) build a southbound auxiliary lane between the Sheffield Drive on-ramp
and the Evans Avenue off-ramp, (f) replace the interchange at Sheffield
Drive, which includes reconfiguring the southbound highway lanes and
ramps, including a reconstructed bridge that would be 118 feet wide and
would contain a single concrete barrier, (g) reconstruct the highway to
remove a nonstandard-crest vertical curve north of Sheffield Drive near
the Romero (Picay) Creek Bridge, which implies lowering the freeway
profile a maximum of 2 feet to accomplish the reconstruction, (h) rebuild
the interchange at Cabrillo Boulevard/Hot Springs, and (i) signals,
landscaping, soundwalls, retaining walls, as appropriate. Specifics for
each alternative are: Alternative 1— selectively widen
inside and outside within available right-of-way, maximizing opportunities
to retain and refine high value resources including scenic views, wetlands
and median/outside landscaping, add median landscaping, where appropriate:
from Carpinteria Creek to Linden Avenue; near the South Padaro Lane
interchange; Nidever Road to Garapato Creek; and near the North Padaro
Lane interchange, build one additional retaining wall to maximize median
planting, on the southbound shoulder at the right-of-way line ending at
the Santa Claus Lane southbound on-ramp (500 feet in length); Alternative
2— add a lane to the outside in order to maximize median
landscaping in the median where right-of-way is available, provide median
landscaping, where appropriate: from Carpinteria Creek to Reynolds Avenue;
and from Santa Monica Road to the Evans Avenue interchange, build three
additional retaining walls to maximize median planting: one on the
southbound shoulder at the right-of-way line ending at the Santa Claus
Lane southbound on-ramp (500 feet in length); one on the northbound
shoulder near Greenwell Creek (700 feet in length); and one on the
northbound shoulder near the northbound off-ramp to Summerland (300 feet
in length.); Alternative 3 — build all new paved lanes
within the existing available median, with the goal of maximizing the
outside planting, provide a single barrier in the median, separating the
two inside paved shoulders, between Carpinteria Creek and Olive Mill Road.
This largely retains the existing outside edge of pavement within these
areas and no additional retaining walls are needed. The Cabrillo Boulevard
interchange would be rebuilt under all three build alternatives. There are
five mutually exclusive interchange configurations—F, F Modified, J,
M, and M Modified—being considered under each of the three build
alternatives. Two of the five configurations (F Modified and M Modified)
would provide northbound access largely in the same way that it exists now
with two northbound exits. One of the configurations would remove the
off-ramp at Hermosillo Road (configuration M), and two configurations
would consolidate the northbound off-ramp traffic at the Hermosillo Road
off-ramp (configurations F and J). The estimated costs of the five
Cabrillo Boulevard interchange configurations include all work from 0.1
mile south of the Hermosillo Road Exit (PM 10.9) to the northern project
limit. The configuration costs are as follows: configuration F is
approximately $40 million; configuration F Modified is approximately $50
million; configuration J is approximately $85 million; and configurations
M and M Modified are each approximately $90 million. Interchange concepts
that include railroad involvement (configurations J, M, and M Modified)
are estimated to cost from $35 million to $50 million more than those that
do not (configurations F and F Modified).

EIR)
In December 2014, it was reported that the CTC approved for future consideration of funding a project that will construct HOV lanes on both sides of US 101 from Carpenteria Creek in the City of Carpenteria to Cabrillo Boulevard in the City of Santa Barbara. The project is not fully funded. The project is programmed in the 2014 State Transportation Improvement Program. The total estimated cost is $467,900,000 for capital and support. Depending on the availability of funds, construction is estimated to begin in Fiscal Year 2018-19. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2014 State Transportation Improvement Program. The resolution indicates that Alternative 1 was selected, with the F Modified configuration for the Cabrillo Road/Hot Springs Road interchange.
In December 2016, it was reported that nearly a year
after a judge ruled that part of its final environmental impact report was
inadequately done, Caltrans on Thursday night presented its revised draft
EIR for the US 101 widening project between Santa Barbara and Carpinteria.
The phase will add a high-occupancy vehicle lane in each direction of the
freeway along the 10.9-mile stretch between the Andree Clark Bird Refuge
in Santa Barbara and just south of Bailard Avenue in Carpinteria. Under
the plan, the interchanges at Sheffield Drive in Montecito and at Cabrillo
Boulevard and Hot Springs Road in Santa Barbara will also be
reconstructed, eliminating the area’s left-hand offramps. The EIR
revision came after a lawsuit challenged the document, arguing that
Caltrans failed to adequately analyze the impacts to local intersections
and cumulative traffic impacts from the project. The original EIR was
approved in August 2014, and Superior Court Judge Thomas Anderle ordered
the revision this past January. Only the intersections section of the
original EIR had to be redone. The revised draft EIR is available on
Caltrans’ website, and the final EIR is expected to be ready in the
spring. “This project is going to be the last freeway lanes that
we’re going to build in this part of the corridor in any of our
lifetimes,” said Scott Eades, Caltrans’ US 101 corridor
manager. “We’re not designing this project to build another
lane at some point in the future. Literally, we’re designing this
project to be the ultimate capacity for this corridor.” The total
estimated cost of the project is $350 million. Intersection mitigations
are expected to contribute anywhere between $1 million and $8 million to
that. According to Caltrans, the project is funded by $140 million of
Measure A funds and $22 million of gas tax money and bond funds. The
remaining funding is anticipated to come from other state and federal
transportation funds.

In March 2018, it was reported that the CTC awarded
$226 million toward the HOV widening project. The money will come from
Senate Bill 1 state gas tax funding and will go toward the project that
eventually will bring a high-occupancy vehicle lane between Santa Barbara
and Ventura County. The 16-mile 101 HOV Widening Project from Santa
Barbara to Mussel Shoals in Ventura County is more than half complete as
of April 2018, according to the Santa Barbara County Association of
Governments. This allocation is the first of two steps to fully fund
construction of the sections from Bailard Avenue in Carpinteria to the
Sheffield Interchange in Montecito. The commission is expected to vote on
an additional $183 million request from SBCAG for SB 1 funding in May. If
awarded the money, construction on the next three segments of the US 101
HOV project, from Bailard Avenue in Carpinteria to past the Sheffield
Interchange in Montecito, can begin in late 2019. The project is funded
through the voter-approved Measure A sales tax and additional state and
federal funding. About 10 miles remain to be constructed. Phase one from
Milpas to Hot Springs was completed in 2012. Phase two from Mussel Shoals
to Carpinteria was completed in 2015. Phase three, the Linden &
Casitas Pass Interchanges Project, is under construction in Carpinteria
and is scheduled to be complete in 2019, a year earlier than scheduled.
The remaining fourth phase has five segments, which could begin in 2020 or
2021: (4A) Segment 4A will complete the US 101 widening in Carpinteria;
(4B) Segment 4B will continue the widening from the western Carpinteria
city limits to the north Padaro Interchange; (4C) Segment 4C will continue
the widening through Summerland and Ortega Hill and include reconstruction
of the Sheffield Interchange in Montecito; and (4D and 4E) the final two
segments, 4D through Montecito and 4E for reconstruction of the Hot
Springs/Cabrillo Interchange, are planned for construction following
segments 4A through 4C. Funding from the new state gas tax, the Road
Repair and Accountability Act of 2017, is critical to maintaining the US 101 construction schedule.

PM SB 1.4/12.3. In and near Carpinteria and the city of Santa Barbara, from 0.2 miles south of Bailard Avenue to Sycamore Creek. Construct HOV lanes. The entry for Santa Barbara County, however, shows that this has been split into two projects: PPNO 7101A HOV lanes, Carpinteria-Summerland, Segs 4A-4C, and PPNO 7101B HOV lanes, Montecito-SB, Segs 4D-4E. All really only have planning funds; there are no construction funds.
In April 2018, it was reported that a judge from the
Santa Barbara Superior Court ruled in favor of moving forward on the South
Coast 101 HOV Lanes Project. The court upheld a Revised Environmental
Impact Report (EIR) which focuses specifically on the topic of
intersections analysis. The ruling by Santa Barbara County Superior Court
Judge Thomas Anderle removes the final remaining hurdle on the South Coast
101 HOV Lanes Project. The project proposed includes new high occupancy
vehicle (HOV) lanes in each direction of US 101 between Bailard Avenue in
the City of Carpinteria and Sycamore Creek (north of Salinas Street) in
the City of Santa Barbara. The project would also reconstruct two
interchanges at Sheffield Drive and Cabrillo Boulevard/Hot Springs Road,
including replacing the left-side ramps with new right-side ones.

In June 2018, the CTC approved a request to amend the
2018 STIP regarding this project. SBCAG and the Department propose that
the South Coast 101 HOV Lanes – Carpinteria through Summerland
Segments 4A-4C (PPNO 7101A) project, in Santa Barbara County be split into
three projects for delivery. The project is part of Santa Barbara 101
Multimodal Corridor that is being delivered by the Department and SBCAG in
phases. At its March 2018 meeting, the Commission adopted the 2018 STIP
that split the original project into two segments (PPNO 7170A and PPNO
7170B), additional funds were programmed to Carpinteria (PPNO 7101A) which
identified Segments 4A, 4B, and 4C. The final phase, PPNO 7101B is not
fully funded. Three phases have already been delivered along the corridor
with various funds. The splitting of the segments into individual projects
as follows: Segment 4A Carpinteria (PPNO 7101C); Segment 4B Padaro (PPNO
7101D) and Segment 4C Summerland (PPNO 7101E) will facilitate the
successful delivery and coordination of the various programs, funding and
partners and is consistent with all of SBCAG’s submittals. This
project is a candidate for the Construction Manager/General Contractor
delivery method, and this action will further align the project for an
innovative delivery of improvements for the corridor. The project is fully
funded and all benefits and outputs remain the same. The splitting of PPNO
7101A into three segments is as follows:

Lanes (PPNO 7101A) project as follows: Segment 4A Carpinteria (PPNO
7101C); Segment 4B Padaro (PPNO 7101D) and Segment 4C Summerland (PPNO
7101E). This split will facilitate the successful delivery and
coordination of the various programs, funding and partners and is
consistent with all of SBCAG’s submittals. This project is a
candidate for the Construction Manager/General Contractor delivery method,
and this action will further align the project for an innovative delivery
of improvements for the corridor. The project is fully funded and all
benefits and outputs remain the same.

In August 2020, the CTC approved a Senate Bill 1 (SB1)
– Solutions for Congested Corridor Program (SCCP) project amendment
to update the funding plan, for the Santa Barbara Multimodal Corridor,
South Coast 101 High Occupancy Vehicle (HOV) - Summerland Segment 4C (PPNO
7101E) and Santa Monica Road and Via Real Intersection Improvements (PPNO
2985) projects in Santa Barbara County. The amendment would reduce the
SCCP funding for the Santa Monica Road Via Real Interchange improvements
(PPNO 2985) project due to project cost savings, and use those savings to
increase the SCCP and local funding and add Highway Infrastructure Program
(HIP) funds for the South Coast 101 HOV - Summerland Segment 4C (PPNO
7101E) to fund the cost increase. The amendment would also split out
follow-up landscape mitigation and monitoring projects (although some of
the concurrent actions related to that were withdrawn in August and likely
pushed to October 2020. The savings on the Santa Monica Road/Via Real
Intersection came about becaue the project was programmed anticipating a
round-about would be the preferred alternative. During the design phase, a
different preferred alternative was determined to be more viable. The
preferred alternative maintains the same level of benefits but, does not
require as many linear feet of sidewalks because it has a smaller
footprint, resulting in construction cost savings of $2,040,000. On the
other side of the equation, the increase on Summerland Segment were due to
retaining wall construction costs. Geotechnical studies were completed
during design phase for Summerland HOV Segment 4C project, which indicated
the need for a retaining wall to protect the highway. The preliminary
geotechnical information was inconclusive, and full studies during design
were completed showing an additional engineering element was needed. This
segment of the highway is directly adjacent to a cut slope above the Union
Pacific Railroad tracks. The wall is necessary to provide stability to the
mainline of the highway as well as address safety issues associated with
rock and debris falling onto the tracks below. The project cost increased
$19,548,000 for a total of $139,848,000 including follow-up landscape and
monitoring. This increased cost will be shared between Local Measure A
funds ($14,408,000), SCCP funds ($2,040,000), and HIP funds ($3,100,000).
The retaining wall is necessary to protect the investment and address
potential safety issues along the highway.

In October 2020, the CTC approved for future
consideration of funding the following project for which a Final Revised
Environmental Impact Report (FREIR) has been completed: US 101 in Santa
Barbara County. Add high occupancy vehicle (HOV) lanes to a portion
of US 101 in Santa Barbara County. (05-SB-101, PM 1.4/12.3) (PPNO 7101)
This project is located in Santa Barbara County on US 101 between the
cities of Carpinteria and Santa Barbara. The Department proposes to add
part-time HOV lanes, and work includes reconstruction of two interchanges
at Sheffield Drive and Cabrillo Boulevard. The primary purpose of the
project is to reduce existing congestion and delays on US 101. The project
is currently programmed in the 2020 State Transportation Improvement
Program (STIP) and the total estimated cost of the project is
$815,750,000. The project has funding from the following programs: STIP,
State Highway Operation Protection Program (SHOPP), Senate Bill 1 (SB 1)
Local Partnership Program, SB 1 Solutions for Congested Corridors Program,
and SB 1 Trade Corridor Enhancement Program. Construction is estimated to
begin Fiscal Year 2020-2021. The scope, as described for the preferred
alternative, is consistent with the project scope programmed by the
California Transportation Commission (Commission) in the 2020 STIP.

In October 2020, it was reported that the second
portion of a five-segment construction project to add peak-period carpool
lanes along US 101 between Santa Barbara and Carpinteira is set to begin
in November 2020. In addition to the new freeway lanes, the US 101:
Summerland project will include new bridges and undercrossings at
Evans Avenue and Sheffield Drive, along with highway ramp and drainage
improvements. On Oct. 22, the California Transportation Commission voted
to allocate approximately $89 million of construction funds for the
project from the Senate Bill 1 Solutions for Congested Corridors Program
(SCCP), Regional Gas Tax Program and State Highway Operations and
Protection Program (SHOPP). The project construction and landscaping costs
are approximately $113 million, according to officials. The US 101:
Summerland project includes locally-inspired design elements that will
highlight the unique community of Summerland at the Evans Avenue
Undercrossing. There will be important drainage improvements and the much
anticipated third lane in each direction throughout Summerland that will
create peak-period carpool lanes to help address ongoing traffic
congestion. The project will also create new right-hand on- and off-ramps
at the Sheffield Drive Interchange. Additionally, improvements are planned
for the on- and off-ramps on Evans and Wallace Avenues and adding two new
sound walls. During Summer 2020, Caltrans and SBCAG applied for state
funding for the two remaining segments in Montecito and Santa Barbara to
complete construction in the area. The CTC will vote on SB1 funding awards
at its November 2020 meeting. Possibly connected to this item or possibly

In December 2020, it was reported that Caltrans has
awarded Granite Construction Segment 4C (Summerland) of the US 101 Santa
Barbara to Carpinteria Construction Manager/General Contractor (CM/GC)
project. The US 101 Segment 4C Santa Barbara to Carpinteria project is the
final phase of a larger program to increase safety, mobility, and provide
congestion relief along US 101 in Santa Barbara and Ventura Counties.
Segment 4C adds 1.7 miles of high occupancy vehicle (HOV) lanes in Santa
Barbara County to reduce traffic congestion between Santa Barbara and
Ventura. The scope of work for the US 101 Segment 4C project includes the
construction of a new HOV lane in each direction, reconstruction of the
existing highway, and rebuilding two interchanges. The project improves
motorist sight distance and enhances aesthetics throughout the corridor.
Granite’s material facilities in Santa Barbara County will supply
aggregates and asphalt concrete for the project.

In May 2021, the CTC received notice that Santa Barbara
County and the Department propose to amend the funding and schedule for
the South Coast YS 101 HOV Lanes – Carpinteria (Segment 4A)
Mitigation project (05-SB-101 1.400/R4.800 PPNO 7101X) in Santa Barbara
County. The intent of this project is to provide resources for biological
staff to complete their mandated annual reports confirming mitigation
success during the five-year monitoring period as required in the
regulatory permits issued by the Regional Water Quality Control Board
(RWQCB). After this monitoring project was programmed, the RWQCB began a
new process of charging annual fees for the review and concurrence of the
reports generated by Department staff. This new requirement means that the
project now needs Right of Way capital funds to pay for the nominal costs
of the annual fees. The project will be adjusted by reducing the Regional
Improvement Program (RIP) funds for construction support programming by
$7,000 and reprogramming these savings to Right of Way Capital to cover
the five years of annual RWQCB’s permit fees. Additionally, the
installation of the mitigation areas has been delayed in order to avoid
conflicts with the parent roadway project construction. Therefore, the
need for this reporting has been pushed back two fiscal years to
correspond with the first annual fee requirement. As a result, the
Department is requesting re-programming of funds from Fiscal Year 2021-22
to 2023-24. This STIP amendment was approved at the June 2021 CTC meeting.

In May 2021, it was reported that work on the next
phase of the widening of Highway 101 from Carpinteria to Santa Barbara
begins June 6. It will be a stretch of just over seven miles from Padaro
Lane to Summerland. Funding is also in the works for the final piece from
Montecito to Santa Barbara, but decisions on that allocation will still
have to be made by state and regional agencies. The project involves
adding an additional lane in each direction, to east the on going
congestion in critical commute times during the week and on weekends. The
current work in Carpinteria is part of a multi phased project involving
new bridges, sound walls, highway reconstruction and landscaping. A
section of the new construction will be dedicated in honor or World War I
veterans. It will be called the Blue Star Memorial Highway and will
represent all branches of the armed forces. 108 new oak trees will be
planted in their honor. There will also be a new bike lane in the months
ahead from Santa Claus Lane to Carpinteria Ave. Caltrans and The Santa
Barbara County Association of Governments (SBCAG) also announced a solid
funding boost for the final phase of the project. It will be $50-million

In August 2022, it was reported that the Montecito
Planning Commission (MPC) completed their review of the US 101 Highway
project through Montecito, sending their recommendations and comments to
the Santa Barbara County Planning Commission (SBPC). This was the final
hearing in a series of three conceptual reviews at MPC. SBPC will consider
the project at two hearings scheduled for both November and December of
2022. The Montecito segment of the project (4D) includes widening 1.4
miles of both directions of the freeway, from just before the Romero Creek
bridge to Olive Mill Road to accommodate a part-time High Occupancy
Vehicle (HOV) lane. The existing roadway pavement on the freeway will be
replaced with 40-year concrete pavement, and the project includes the
installation of median barriers, guardrails, fencing, retaining walls, and
new landscaping, reconstruction of the freeway bridges over Cabrillo
Boulevard plus a new southbound on-ramp, and replacement of the bridges
over Romero Creek, San Ysidro Creek, and Oak Creek. The project also
includes the removal of 158 oak trees (to be replaced at a 3:1 or 2:1
ratio) and 20 other native trees (to be replaced at a 1:1 ratio). Safety
improvements of the project include increased stopping sight distance,
exterior shoulders for disabled and emergency vehicles, new safety
barriers, enhanced pavement markings and signs, and safety lighting at
ramps. New components of the project will result in reduced maintenance,
according to project reps. As in previous hearings, Planning Commissioners
continued to take great issue with the removal of sound walls from the
project, which were removed earlier this year after analysis showed an
increase in water rise during a 100-year flood event, using the
County’s Recovery Mapping that was adopted in response to the 1/9
Debris Flow. The Recovery Mapping is based on a 100-year rain flow event,
with additional conditions that all culverts and bridges are blocked, as
well as a burned watershed area, which contributes to a broader flow of
water over the area. According to Santa Barbara County Flood Control reps,
the freeway has flooded seven times since 1960, and was closed for two
weeks following the 1/9 Debris Flow in 2018. Flood Control reps are
adamant that they do not support sound walls in Montecito as part of this
project, despite new resiliency measures including larger (or new) debris
basins, creek nets, and enhanced bridges. Commissioners also considered
the timing of two parallel projects as part of the highway construction:
the Olive Mill roundabout, slated to begin construction in November, as
well as the San Ysidro roundabout, slated to begin construction in Spring
2023. Construction on the freeway project is expected to begin in Summer
2023, and will take 2.5 years to complete. Commissioners asked the team to
try and avoid repeat on- and off-ramp closures, and to stagger the
roundabout and freeway construction in the most efficient way
possible. Commissioners formulated a handful of recommendations to
be sent to the Planning Commission. They stated that if the new watershed
study that is being undertaken allows for sound walls, Caltrans shall
construct sound walls that will accommodate the passage of water, and that
Caltrans shall include the sound walls in their funding request. They also
stated that the project shall be designed and constructed such that future
sound walls can be accommodated (i.e. the footings for sound walls shall
be installed). Also related to the sound walls, the Commission asked that
if sound walls are not constructed as part of the project, the four-foot
wall extending from a retaining wall in front of the Miramar Resort on the
south side of the freeway shall be modified or removed to avoid sound
reflectivity. Other recommendations included asking that the Olive Mill
roundabout be operational prior to the construction on the freeway; tree
removal be minimized and on-site replanting shall be prioritized; and
reclaimed water shall be used for dust mitigation for highway construction
and landscaping shall be irrigated with recycled water, where feasible. An
additional comment was that the freeway bridges be constructed to
accommodate a 100-year storm event to ensure that the proposed bridges
will not be a limiting factor that prevents sound walls from being built
in the future. In place of the sound walls, a black coated chain link
fencing, planted with vines and landscaping, is proposed; Caltrans has
agreed to provide landscape maintenance for five years after the project
is built.At the request of MPC chair Ron Pulice, Ayars reported that
neighborhood chatter related to removal of the southbound on-ramp at
Posilipo is not considered part of this project. While the entrance at
Posilipo will be enhanced during construction, neighbor discussions hoping
for the entrance’s removal are happening outside of the scope of the
project, and any project to consider removal of the entrance would require
significant planning and public input.

In October 2022, it was reported that a $75 million
federal loan will help cash-flow needs for the massive US 101 corridor
project, adding a third lane from Santa Barbara to Carpinteria. The U.S.
Department of Transportation has closed more than $38 billion in
Transportation Infrastructure Finance and Innovation Act loans, and the
recent federal infrastructure bill provided more capital for the program.
Its Build America Bureau provided a 4.02% interest, $75 million loan to
build 7.5 miles of high-occupancy vehicle lanes in Santa Barbara County
for the US 101 corridor project. The loan funding will help the agency
leverage Measure A dollars and provide the cash flow to keep construction
moving forward. SBCAG won’t necessarily need to draw down the full
loan amount of $75 million, but it gives the agency cash flow to keep
construction contracts going as soon as sections of the project are ready.
Construction is underway on the highway section between Carpinteria and
Summerland. The 2.5-mile segment between Montecito and Santa Barbara is
still unfunded to the tune of $256 million. Local funding for the project
has come from the voter-approved Measure A half-cent sales tax measure.

In July 2023, it was reported that the California
Transportation Commission has awarded $132.4 million to the Santa Barbara
portion of the massive US 101 project. $145 million is required to
fully fund the remaining construction that ends at Sycamore Creek in Santa
Barbara. The Montecito portion of the project is currently under
construction, and so are parallel projects including the San Ysidro Road
roundabout.
The $132.4 million award will fund the following components of the US 101

In June 2023, the CTC adopted the 2022 Solutions for
Congested Corridors Program, which included the following program: Santa
Barbara U.S. 101 Multimodal Corridor Project - Three Creeks in Santa
Barbara County ($132,400,000) is a community-driven and complex
multimodal project which provides improved non-vehicular and vehicular
mobility options between the regularly congested Counties of Santa Barbara
and Ventura. This project includes completing a gap on US 101 with
continuous high occupancy vehicle lanes (segments 4D, 4E), peak-hour
passenger rail service, enhanced regional and local transit service, and
the completion of the California Coastal Trail to increase biking and
walking. This suite of improvements will rebuild the community’s
only highway and economic lifeline by making it efficient, safe, and
equitable, and reconnecting local neighborhoods that have been
historically disenfranchised from active transportation choices. This
project will also provide improved interregional accessibility for small
communities along US 101, commuters that travel from Ventura to Santa
Barbara, freight trucks, and travelers. In the staff recommendations
released on June 8, 2023, the recommended funding amount for this project
was reported inaccurately as $107.4 million by Commission staff, which is
$25 million less than the original request. Therefore, the recommended
funding amount has been increased to $132.4 million to fully fund the
project.

Carpinteria Improvements (approx SB 2.622 to SB 4.446)
In June 2008, the CTC received a
notice of preparation for roadway improvements on a portion of Route 101
near Carpinteria in Santa Barbara County. The project is not fully funded.
The project is programmed in the 2008 State Transportation Improvement
Program (STIP) for project development, right of way and construction
support for $50,468,000. Total cost of the project is estimated to be
$100,451,000. Construction is estimated to begin in Fiscal Year (FY)
2013-14, depending on the availability of funds. There are five
alternatives being considered for the project.
In February 2009, the CTC received the Draft EIR on the above project for review. The alternatives changed slightly:
In November 2010, the CTC approved for future consideration of funding a project in Santa Barbara County that will make operational improvements to Route 101 in the city of Carpinteria by reconstructing the Linden Avenue and Casitas Pass Road interchanges, reconfiguring on and off ramps, replacing Route 101 bridges over Carpinteria Creek and reconstructing bike paths. The project is not fully funded. The project is programmed in the 2010 State Transportation Improvement Program for project development only. Construction is estimated to begin in Fiscal Year 2013-14. Total estimated project cost is $101,171,000 for capital and support. Resources that may be impacted by the project include; land use, farmlands, biological resources, visual resources, water quality, and noise. Potential impacts associated with the project can all be mitigated to below significance through proposed mitigation measures.
In July 2020, it was reported that after 25 years, the
bridges have been completely replaced at Linden Avenue and Casitas Pass
Road. Each bridge has additional vehicle lanes, along with bike lanes that
connect to a larger city bicycle network for safe riding to downtown, the
beach and south to the Rincon. There, a Class One bike lake provides a
safe route to Ventura. The bridge improvements were necessary to complete
the freeway expansion from two lanes in each direction to three lanes in
each direction. The old bridges were outdated and did not provide the room
to widen the highway. The project also includes more signal lights in a
city that, for years, only had three signalized intersections. Now there
are eight locations for lights. They will be flashing red for the the
first week of operation, then go into their normal cycle. The Casitas Pass
bridge has room for a center parkway that will have palm trees for a
welcoming overcrossing into the downtown corridor. The work was completed
five months ahead of schedule.
(Source: KEYT, 7/9/2020)
In December 2018, it was reported that (as part of the Route 192 bridge
reconstruction project), Construction crews were working on the Olive Mill
Road overpass on US 101 (~ SB 10.537) near the Montecito Inn, which had
its railings destroyed and washed away by the Jan. 9, 2018 debris flow.
New bridge rails have been completed on the eastern side of the overpass
and crews were working on the western side.
(Source: SB Noozhawk, 12/5/2018)
In September 2010, the CTC approved relinquishment of right of way in the city of Santa Barbara along Route 101, on Hot Springs Road, Old Coast Highway, and Coast Village Road, consisting of collateral facilities (5-SB-101-PM 11.3).
Cabrillo Interchange (approx SB 11.402)
In May 2012, it was reported that the Cabrillo
Interchange reconstruction was creating controversy. The preferred
Caltrans alternative, known as “F modified,” that takes away
the left hand ramps, but installs a new northbound off ramp at Cabrillo
Boulevard. Some residents have seized on this being the best option the
community is likely to get, given that it’s the only one that keeps
traffic away from Coast Village Road. Others believe that a better
alternative could still be worked out with Caltrans. Hermosillo Road
residents demanded to know why the Montecito board had sent a letter to
Caltrans with wording that some residents felt implied support of using
Hermosillo Road as the primary exit. The residents demanded the board take
a stance on preventing Hermosillo Road from becoming the new beach
thoroughfare. Some feared that losing the ramps without building a new
right hand ramp would send tourists, airbuses, and other vehicles
ill-suited to the roundabout through Coast Village Road.
(Source: Daily Sound, 5/17/2012)
In January 2013, it was reported that a group called Common Sense 101 was protesting the plans in Montecito and proposing a "Plan B". They have a
link to their proposal, but it is mostly graphics and does not contain a specific written description of the changes. Their proposal supposedly takes less time, costs less
money, and keeps the freeway open. It is unclear whether it addresses all
of the same goals.
(Source: Pacific Business Times, Common Sense 101)
In December 2013, it was reported that Caltrans had rejected the proposal from Common Sense 101, and that they want to move forward with the original proposed South Coast Highway 101 HOV Project.
Cacique Street Improvements (approx SB 12.672)
In December 2009, the CTC approved for future consideration of funding a project that will construct operational improvements to the existing four-lane Route 101 including additional lanes, new and reconfigured ramps, replacement/widening of Milpas Street Undercrossing and Sycamore Creek Bridge, new Cacique Street Undercrossing, and bicycle/pedestrian facilities in the city of Santa Barbara. The Department and the Federal Highway Administration originally approved the FEIR/FONSI in 2004. In November 2007, the Commission allocated $53,043,000 programmed in the 2006 State Transportation Improvement Program (STIP). At that time, the landscape scope of work was split to form a parent project (PPNO 0478) and a child project (PPNO 0478Y). The revalidation of the document is needed for the landscaping project (PPNO 0478Y), acknowledges the addition of scope that was added in 2005, and corrects inaccuracies in the Notice of Determination that was filed in 2004. The landscape project is programmed in the 2008 STIP for $3,065,000, capital and support. Construction is estimated to begin in Fiscal Year 2009-10.
In April 2012, it was reported that Caltrans opened the
gate between two sides of Cacique Street previously blocked by US 101. A
two-lane road with bike lanes now flows under the raised highway, better
connecting drivers, cyclists, and walkers of the lower Eastside
neighborhood with nearby business and the beach, and allowing them to
bypass the tricky Milpas roundabout. The corridor opened in conjunction
with the completion of new third lanes on US 101 between Milpas Street and
Hot Springs Road. These first-phase improvements, four years of
construction and $57 million in the making, included the overhaul of two
major interchanges, work on six new or improved bridges, and the Montecito
roundabout. It was the largest Caltrans project in Santa Barbara since the
crosstown route was completed in the early 1990s. The voter-approved
Measure D, a local sales tax that helps pay for such traffic-improvement
ventures, contributed $13 million toward the $57-million price tag.
(Source: Santa Barbara Independent, 4/4/2012)
In October 2011, the CTC approved relinquishment of right of way in the city of Santa Barbara, adjacent to Route 101 and underlying the Milpas Street roundabout, consisting of collateral facilities (05-SB-101-PM 12.75).
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $800,000 for High Priority Project #246: Operations and management improvements, including Intelligent Transportation System (ITS) technologies on US 101 in Santa Barbara County.
In May 2005, the CTC considered relinquishment of right of way in the City of Santa Barbara, between Lawrence Street to 0.6 mile westerly of State Street, consisting of reconstructed and relocated city streets, frontage roads, and cul-de-sacs. (5-SB-101-PM R12.8/R14.2)
San Jose Creek Bridge № 51-0163L/R Replacement (05-SB-101 PM 21.4/21.9)
The following project was included in the final adopted 2018 SHOPP in March 2018: PPNO 2649. 05-Santa Barbara-101 21.6. US 101 In Goleta, at San Jose Creek Bridge № 51-0163L/R. Replace
bridges to maintain standards of safety and reliability. Begin Con:
6/15/2022. Total Project Cost: $16,960K.The existing San Jose Creek Bridge
was built in 1946 and widened in 1989.The existing structure is about
100-feet long and 114-feet wide and has three spans with 58 columns placed
in the creek channel. The bridge has six12-foot-wide lanes, two
8-foot-wide inside shoulders, two 8-foot-wide outside shoulders, and a
22-foot-wide center median.
In April 2020, it was reported that the public comment
period for a proposal to replace the San Jose Creek Bridge on US 101 near
Route 217 in Goleta was opening. The bridge replacement is aimed to ensure
reliability of the highway would be designed as a single-span bridge that
would meet current standards. The project would replace the existing
bridges with a new single bridge structure. The new bridge will be in the
same location as the existing bridge. The proposed project also includes a
standard bicycle pedestrian path on the north side of Route 217, according
to Caltrans officials. According to the proposed mitigated declaration,
building the new bridge would involve the following:removing the existing
bridge structure and building a new bridge structure, removing the
existing slope pavement on the creek banks, installing rock slope
protection, replacing traffic barriers to meet current safety standards
and minor earthwork. The total cost estimate for project construction is
about $19,515,000, with an estimated escalated cost of about $22,982,000.
Project construction is expected to start in the 2022-2023 fiscal year,
and end in the 2024-2025 fiscal year. Project construction is expected to
take about 280 working days spread between two construction seasons.
Typical construction season occurs between June to October.

Santa Barbara County. The Department proposes to replace northbound and
southbound San Jose Creek bridges to address the presence of reactive
aggregates in the existing structure. The new bridge design would be a
single-span structure and will be located at the existing location. This
project is not fully funded and is currently programmed in the 2020 SHOPP
for a total of $17,064,000, of which $12,720,000 is currently through G-13

Roadway Improvements - Goleta Area (approx SB 26.898)
In March 2007, the CTC considered for future
consideration of funding Route 101 in Santa Barbara County – Roadway
improvements near Goleta. This project in Santa Barbara County will
replace an existing overcrossing and construct roadway improvements
associated with the new overcrossing. The project is fully funded in the
2006 State Highway Operation and Protection Program (SHOPP). The total
estimated project cost is $6,880,000. It is estimated to begin
construction in Fiscal Year 2008-09.
In August 2011, the CTC approved $640,000 and $100,000 in SHOPP funding for repairs in Goleta, at Cathedral Oaks Overcrossing Bridge #51-0331, and at Cathedral Oaks Overhead Bridge #51-C0344 that construct replacement planting at two structures.
In his 2006 Strategic Growth Plan, Governor Schwartzenegger proposed widening US 101 in Santa Barbara and Ventura County.
Refugio Road Bridge (SB R36.0/R37.0)
In March 2019, it was reported that Caltrans was starting public meetings on a bridge
replacement project involving two bridges on US 101 along the Gaviota
Coast: Both the north and southbound bridges at the Refugio Road
undercrossing, eight miles west of Goleta, need to be replaced. The
projected cost is $51 million and the proposed timeline is 2023 to 2026.
It appears the project was part of the 2014 SHOPP, according to a May 2014 Project Scope Summary Report. The bridges, which were built in 1974, feature continuous reinfored concrete box girders on single column bents
with driven concrete piles and open end diaphragm abutments. Cracking was
noted in 1995, and there is the presence of Alkali-Silica Reactivity. The
new bridges will match the existing in terms of length and profile, but
will be 6'4" wider to provide standard inside shoulders and upgraded
railing. They will also have a constant depth, as opposed to the variable
depth of the current bridges. There are two alternatives proposed in the
2014 report: a two-span CIP PT box girder structure and a three-span CIP
PT box girder structure. The three span structure is recommended because
it reduces the permanent impact to the Canada Del Refugio Creek channel by
eliminating the existing bents on the bank of the creek.

long lead project did not have costs associated to PS&E and
construction support. Change in R/W support is due to significant impacts
to cultural resources determined in PA&ED which require additional
studies. Additional R/W capital is due to the requirement of Fish Passages
previously not required. Updated total cost: $46,929K.

In March 2020, the CTC approved a request for
supplemental funds related to this project. This project is located on US 101 near the City of Goleta, in Santa Barbara County. The project
will replace the right and left Refugio Road Undercrossing Bridges over
Cañada del Refugio Creek, and upgrade existing barriers on the
northbound on-ramp to current standards with see-through railing. The
bridges were built in 1974, and the Department has concluded that they are
structurally deficient. In addition, the project will replace the
interchange lighting system due to observed conduit degradation. The
project will also modify the Cañada del Refugio Creek channel lining
within the Department Right-of-Way (R/W) and the existing adjacent
drainage easement to remove a partial barrier to fish passage and enhance
habitat conditions.The PA&ED phase was allocated in June 2017 for
$2,200,000; with the available G-12 authority, the total allotment for the
PA&ED phase is $2,620,000, of which $2,366,000 has been expended as of
March 2020. The Department requested supplemental funds in the amount of
$990,000 to complete the PA&ED phase and deliver this project by the
planned delivery in 2022-23 and advertise and award the project contract
in time for the 2024 construction season. The programmed budget for the
PA&ED phase was based on the required permits and environmental
analysis that recommended a Mitigated Negative Declaration/Categorical
Exclusion (MND/CE) in 2015. These documents included the need for a
Coastal Zone permit for significant modifications to existing
infrastructure, the requirement for other permits that would be expected
to take significantly longer periods of time to obtain, and potential
effects to a cultural site. These requirements also include the need to
process documents that will present a higher risk of delays, including
additional studies, data recovery, and consultation with the State
Historic Preservation Officer (SHPO) and Native American tribes due to
cultural site impacts and impacts to federal and state protected species.
Later during the PA&ED phase, the Department concluded that the
project’s impacts to an existing cultural site would be irreversible
and could not be fully mitigated, and in November 2018 the Department
elevated the required environmental document from an MND/CE to an
Environmental Impact Report/Environmental Assessment (EIR/EA). This
higher-level document requires the issuance of a Notice of Preparation
(NOP), a scoping meeting, and greater coordination between state and
federal agencies. A public hearing will be required upon the release of
the Draft EIR/EA.

In April 2023, the California Coastal Commission had
the following agenda item: Application No. 4-22-0459 (Caltrans).
Application of Caltrans to replace the Northbound and Southbound US 101
bridges at Refugio Creek with new clear span bridges with five traffic
lanes, standard bridge railings and shoulders, fish passage improvements,
pedestrian path upgrades, and restoration of public parking on Refugio
Rd., near Refugio State Beach in unincorporated Santa Barbara County. The
more detailed description of the project was: Replace the existing
two-span Refugio Road Undercrossing Bridges with new clear span bridges,
standard bridge railings and shoulder, the degraded lighting system in the
project area, as well as the railings on northbound on-ramp bridge over
Cañada del Refugio Creek; maintain a Class III bicycle lane in both
directions; reconstruct portions of Refugio Road, including restoration of
a portion of public parking that was lost due to installation of
unpermitted “No Parking” signs; and improvement of
existing pedestrian trail along Refugio Road that leads to the
Refugio State Beach entrance; improve steelhead trout migration in
Cañada del Refugio Creek by removing existing rock slope protection;
and relocate existing underground water line and aboveground fiber optic
cable. The staff recommendation noted that the design of the new bridges
will eliminate the need for columns, which are presently adjacent to the
creek. It was noted that Caltrans proposes to mitigate for all impacts to
coastal scrub on-site through restoration, establishment and enhancement
of local coastal scrub communities totaling over 6 acres (3:1
ratio). Mitigation efforts will include container plantings and
hydroseeding as well as targeted weed control and removal. Caltrans will
perform mitigation for habitat and wetland impacts pursuant to its
proposed Mitigation and Monitoring Plan. To ensure that the mitigation
meets the proposed performance standards, the project is conditioned to
require Caltrans to comply with the approved Habitat Mitigation and
Monitoring Plan and to provide annual monitoring reports to the Executive
Director for five years following implementation. Lastly, Caltrans has
agreed to a condition to contribute $75,000 to the County of Santa
Barbara toward the planning, design, and construction of the Paradiso del
Mare (Paradiso) trail to mitigate for the temporal loss of free parking on
Refugio Road that resulted from unpermitted installation of
“No Parking” signs. The Paradiso trail will be a segment of
the California Coastal Trail located approximately 9 miles south of the
project site. Commission staff worked with Caltrans, the Coastal
Conservancy, and the County of Santa Barbara to identify this shovel-ready
public access project.

In August 2023, the CTC approved the following project
for future consideration of funding: 05-SB-101, PM R36.0/R37.0. Refugio
Road Undercrossing Bridges Replacement Project. Remove and replace
the existing Refugio undercrossing bridges, remove the concrete-grouted
rock slope protection to remove a fish passage barrier, upgrade the
nonstandard bridge railings from the Cañada Del Refugio northbound
on-ramp bridge, replace the degraded lighting system, and rehabilitate the
pedestrian pathway beneath the bridge, in Santa Barbara County. The
project is located on US 101, from PM R36.0 to PM R37.0, in Santa Barbara
County. The Department proposes to remove and replace the existing Refugio
undercrossing bridges, remove the concrete-grouted rock slope protection
to remove a fish passage barrier, upgrade the nonstandard bridge railings
from the Cañada Del Refugio NB on-ramp bridge, replace the degraded
lighting system, and rehabilitate the pedestrian pathway beneath the
bridge. The project is currently programmed in the 2022 SHOPP for a total
of $61,502,000, which includes Right of Way (Capital) and Construction
(Capital). Construction is estimated to begin in 2023-24. The scope, as
described for the preferred alternative, is consistent with the project
scope as programmed by the Commission in the 2022 SHOPP. A copy of the
FEIR has been provided to Commission staff. The Commission approved the
project for future consideration of funding on March 25, 2021, under
Resolution E-21-37. Since the approval of the FEIR, there have been
changes to the project and an Addendum was prepared pursuant to CEQA.
These changes include adjusting the footprint of the access road through a
landowner’s property, widening the inside shoulder of NB US 101 from
5-feet to 10-feet, replacing two 18-inch culverts and adding two
archeological monitoring areas (AMA-2 and AMA-3) to the plans and
specifications to cover the work, adding stairs to connect historical
parking on Refugio Road with the reconstructed pedestrian path, and adding
a secondary access ramp from Refugio Road to Refugio Beach to improve
accessibility. In addition, Southern California steelhead is now a
candidate species pursuant to the California Endangered Species Act, and
the Environmental Commitments Record has been updated to include measures
from the project specifications, permits, Biological Opinions, and Coastal
Mitigation and Monitoring Plan. The changes are minor and do not result in
new or increased environmental impacts. The project changes do not meet
the criteria outlined in CEQA Guidelines Section 15162 and Section 15163
to prepare a Subsequent or Supplemental FEIR. The Department subsequently
completed an Addendum to the FEIR pursuant to CEQA. The Department has
approved this project for construction. This approval and the Addendum
will satisfy the environmental requirements for this stage of the planning
process.

In October 2023, the CTC approved the following SHOPP
construction phase allocation: $60,971,000. 05-SB-101 R36.0/R37.0. PPNO
05-2448; ProjID 0513000018; EA 1C950. US 101 Near Goleta, from 0.6 mile
south to 0.4 mile north of Refugio Road Undercrossing № 51-0215L/R
and Canada del Refugio № 51-0030S. Outcome/Output: Replace two
bridges and upgrade bridge railing on one bridge. CEQA - EIR, 2/5/2021;
Re-validation 6/30/2023. NEPA - FONSI, 2/5/2021; Re-validation 6/30/2023.
Future consideration of funding approved under Resolution E-21-37; March
2021. As part of this allocation request, the Department is requesting to
extend the completion of CONST and CON ENG an additional 15 months
beyond the 36 month deadline. Four month allocation time extension for
CONST and CON ENG approved under Waiver 23-72; June 2023. SB 1 Baseline
Agreement approval under Resolution SHOPP-P-2021-07B; June 2021.
Allocation (Allocated / Programmed (if different)): CON
ENG $11,200,000; CONST $40,900,000 / $49,771,000 (21.7%
increase). The Construction Capital estimate is greater than the
programmed amount due to the increase in concrete prices as shown in
recent bids. The main component of this project is the replacement of two
bridges which will require a comprehensive method for demolition of the
existing bridges. The demolition plan originally assumed a more
efficient method of removal. However, given the presence of a creek,
removal requires a more controlled method of removal. After review
of the final Structures
PS&E submittal in December 2022, it was noted that concrete prices
have gone up as shown in recent bids. The Department updated the EE
bid items including structure concrete, bridge and structure concrete,
bridge polymer fiber to the current market conditions. These items
as well as other bid items for steel piling and prestressing concrete were
updated resulting in the structures estimate increasing by $7,179,000.
Some of the other significant cost increases are attributed to
mobilization, traffic control related items, and the resident
engineer’s office. The remaining increase is due to minor unit
price cost increases of other bid items.

In December 2016, it was reported that the Director of the State
Department of Transportation (Caltrans) has informed the Santa Barbara
County Board of Supervisors (Board) that US 101 along the Gaviota Coast is
California's newest officially designated State Scenic Highway. The
designated segment travels through one of the longest remaining rural
coastlines in Southern California along 21 miles of US 101 from the City
of Goleta's western boundary (SB 27.728) to Route 1 at Las Cruces (SB
R48.766). This landmark designation was made possible by a partnership
between the Gaviota Coast Conservancy, County of Santa Barbara Planning
and Development Department, Third District Supervisor Doreen Farr and
Caltrans Landscape Architecture Division. The County's coastal visual
policies and California State Park's natural and cultural preservation
mandates have protected the scenic quality along the Gaviota Coast for
decades, and will be further enhanced under this new designation. The
Gaviota Coast State Scenic Highway includes spectacular views of the
Pacific Ocean, grassy rolling hills, and the Santa Ynez Mountains. The
route also adjoins three stunning California State Parks: Gaviota and
Refugio State Parks, and El Capitán State Beach.

Gaviota Realignment (approx SB 44.841 to SB 46.351)
In March 2014, the CTC approved for future consideration of funding a project in Santa Barbara County near the town of Gaviota that will realign the northbound side of Route 101, including replacing the existing curve, widening the shoulders, and constructing other modifications.
In January 2016, the CTC approved SHOPP funding on US 101 in Gaviota, from 0.7 mile north of Beckstead Overcrossing to 0.8 mile south of Gaviota Tunnel. Outcome/Output: Realign highway, replacing multiple sharp curves with a single curve that will provide improved visibility around the curve. The project will reduce the number and severity of collisions.Future Consideration of Funding approved under Resolution E-14-07; March 2014. $6,979,000
In April 2016, it was reported that a project to
re-align the northbound lanes and straighten a curve along US 101 from
north of Mariposa Reina to south of the Gaviota State Roadside Rest Area
was beginning. For the duration of this project, motorists going
northbound on US 101 will be unable to turn left onto Gaviota Beach Road
to access Gaviota State Park and the Hollister Ranch or turn left onto
northbound US 101 from Gaviota Beach Road. Northbound motorists may detour
at the Route 1 Interchange north of the tunnel before returning
southbound. The contractor for this $6.6 million dollar project is Souza
Construction of San Luis Obispo, CA. This project is expected to completed
in December 2016, weather permitting.

consideration of funding the following project for which a Mitigated
Negative Declaration (MND) has been completed: US 101 in Santa Barbara
County (05-SB-101, PM 56.0). Upgrade railings and construct improvements
on an existing bridge on US 101 near the city of Buellton. (PPNO 2561)
This project is located on US 101, south of Buellton in Santa Barbara
county at the Nojoqui Creek Bridge (№ 51-0018 L/R). The project
proposes to replace the bridge rails. The proposed project would also
widen both bridges as well as widen current shoulder standards. Four
columns and footings to support the widened structure would also be
constructed. This proposed project addresses the nonstandard left and
right shoulders of the bridges and the need to upgrade the bridge rails
not approved with current crash-worthiness measures under the Structure
Replacement and Improvements Needs Report and the Office of Structures
Maintenance. The proposed project is estimated to cost approximately $9.9
million. This project is fully funded and is currently programmed in the
2018 SHOPP for approximately $9.5 million. Construction is estimated to
begin in Fiscal Year 2019-20. The scope, as described for the preferred
alternative, is consistent with the project scope programmed by the
Commission in the 2018 SHOPP.

project will construct a new single span bridge by bridging the median gap
between the former structures. The US 101 structure approaches, bridge
rails, metal beam guardrail, and end treatments will be replaced and
sidewalk with pedestrian railing as needed has also been added to the
project along Route 135 to improve pedestrian connectivity. The project
will accommodate planned traffic staging during construction and maintain
two lanes open to traffic in each direction on US 101. This project was
programmed for delivery in 2019-20, and the Department is requesting an
allocation time extension concurrently with this COS supplemental funds
request. The PS&E phase was allocated in August 2017 for $1,800,000,
and with the available G-12 authority, the total allotment for the
PS&E phase is $2,180,000. The Original Project Scope Study Report
(PSSR) was developed in June 2015. At the time the project was programmed,
the structures work only included replacing the superstructures and
retrofitting the bent columns. Since the original programming, it was
discovered that the project site had liquefaction potential and the
project will now replace the bridges completely instead of only replacing
the superstructures.

Santa Maria Widening (approx SB 84.352 to SB 90.77)
There are plans to widen US 101 to 6-lane freeway from 0.4 km south of Santa Maria Way Undercrossing to Route 135/US 101 Separation in Santa Maria . This was on the July 2005 CTC agenda. In February 2006, the CTC considered adding funding. The proposal noted that the widening would be within the existing 46 to 56-foot median area. The existing inside shoulders would be removed and the entire median area paved to include two 12-foot traveled lanes, two 10-foot inside shoulders and a type 60 concrete median barrier placed in the area between the inside shoulders for the entire length of the project. There are also five locations where soundwalls are to be constructed.
In December 2008, the CTC reviewed a draft EIR regarding construction of a new interchange for Santa Maria and
the community of Orcutt. The interchange would be constructed between
Clark Avenue overcrossing and Santa Maria Way undercrossing and extend
Route 58 (note: The CTC document said Route 58, but Route 58 isn't in that
area--it ends at Route 1 in Santa Margarita) approximately 1.6 miles in
length in the community of Orcutt. The project is not fully funded. The
project is programmed in the 2008 State Transportation Improvement Program
(STIP) with Regional Improvement Program and Regional Surface
Transportation Program funds for $12,782,000. The total cost of the
project is estimated to be $36,100,000. Construction is estimated to begin
in Fiscal Year 2013-14. There are four alternatives identified in the
draft EIR:
In March 2012, the CTC approved for future consideration of funding the Union Valley Parkway extension. This project in Santa Barbara County will extend the Union Valley Parkway east to west approximately 1.6 miles and construct an interchange with US 101 just south of the City of Santa Maria. The project is not fully funded. It is expected that the necessary funding will be come from the Santa Barbara County’s formula State-Local Partnership Program shares. The project is programmed in the 2010 State Transportation Improvement Program (STIP). The total project cost is $24,430,000 for capital and support. Depending on the availability of funding, construction is estimated to begin in Fiscal Year 2011-12. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2010 STIP. Funding was authorized in April 2012, contingent on the passing of the budget act.
In February 2013, it was reported that Stage 1 work continues on the Union Valley Parkway interchange. It includes earthwork, ramp and road construction and construction of bridge abutments. Pile-driving work on the east abutment and in the median has been completed. Work continues on the west side of the freeway. Crews have graded the new southbound on- and off-ramps, and they soon will be paving both ramps. The southbound ramps will be used as a detour during nighttime closures when the bridge falsework is built. The $10.3 million project is scheduled to be completed by early 2014. It is the final piece of the Union Valley Parkway that will connect US 101 to Orcutt, Route 135 and the Santa Maria Public Airport.
Santa Maria Bridge (SB PM 91.0 to SLO PM 0.8)
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $2,720,000 for High Priority Project #1092: Widen the Santa Maria River Bridge on US 101 between Santa Barbara County and San Luis Obispo County.
In 2007, the following requests for funding from the Corridor Mobility Improvement Account (CMIA) were made, but not recommended for funding: Operational improvements Phase 1b in San Luis Obispo county ($5,432K requested); widening of the Santa Maria River Bridge ($58,540K requested).
In July 2010, the CTC approved for future consideration of funding a project that will construct roadway improvements including bridge widening and an additional northbound and southbound lane on Route 101 near the city of Santa Maria. The specific limits of this project are from SBA PM 91.0 to SLO PM 0.8. The project is programmed in the Corridor Mobility Improvement Account and the 2010 State Transportation Improvement Program. Construction is estimated to begin in Fiscal Year 2009-10. Total estimated project cost is $49,302,000 for capital and support. The scope as described for the preferred alternative is consistent with the project scope set forth in the project baseline agreement.
In February 2013, it was reported that Stage 2 work continues on the river bridge with the southbound deck currently being poured. The concrete decking is about halfway finished. The southbound side of the bridge will hold two lanes and a pedestrian and bike lane when completed. The $34.8 million project is scheduled for completion by the summer of 2014.
Willow Road, Nipomo (SLO 6.4)
In January 2010, the CTC approved a new public road connection at Willow Road to US 101, in the community of Nipomo, at Post Mile (PM) 6.4, in San Luis Obispo County. The proposed project includes the extension of Willow Road across US 101 to Thompson Road with the intention to provide a much needed east-west arterial connection to Route 1 and the Callender area. The project will also relieve future traffic demand at the adjacent Tefft Street and Los Berros Road/Thompson Road interchanges. The Nipomo area is served by three interchanges on US 101: Hutton Road (Route 166) on the south, Tefft Street in the central area, and Los Berros Road/Thompson Road on the north. Recent traffic forecasts for the Nipomo area predict that the existing Tefft Street interchange and the existing Los Berros Road/Thompson Road interchanges will be inadequate to serve projected development during peak traffic periods. Motorists would be subjected to recurring congestion and delays due to increasing traffic on US 101 and on the existing local street network. Of the three interchanges, only the Tefft Street interchange is located centrally to existing and planned developments. Los Berros Road/Thompson Road and Hutton Road (Route 166) are located at the fringe of future development.
In October 2009, the CTC approved for future consideration of funding a project that will construct the extension of Willow Road and connect it with US 101 in the community of Nipomo, south San Luis Obispo County. The proposed project includes the extension of Willow Road east from its existing terminus approximately 1,000 feet west of Pomeroy Road to Thompson Avenue; construction of a frontage road between Willow Road and Sandydale Drive; and construction of a new US 101/Willow Road interchange. In March 1999 a Tier I Final Environmental Impact Report (FEIR) for the project was adopted by the County Board of Supervisors and a preferred alignment and interchange were selected. The FEIR specified that subsequent design refinements for the road extension, interchange, and frontage road would be evaluated in a Tier 2 construction level environmental document. The County prepared the FSEIR to satisfy the requirements for evaluating the preferred alternative in a Tier 2 construction level environmental document. The FSEIR was prepared for the entire US 101/Willow Road Interchange Project. However, for construction and financing purposes, the County split the project into two phases as follows:
In May 2016, the CTC approved a STIP amendment to program an AB 3090 cash reimbursement project (PPNO 0690B) in order to use local funds for construction of the US 101/Willow Road Interchange project (PPNO 0690A) in San Mateo County. The San Mateo County Transportation Authority requested reimbursements over a three-year period beginning in Fiscal Year (FY) 2017-18. If the proposal is adopted by the Commission, SMCTA further proposes to advance project delivery with the use of $8,000,000 in local sales tax (Measure A) funds for construction support, and request reimbursements in FYs 2017-18, 2018-19 and 2019-20. In August 2016, they modified this to request reimbursements over a two-year period beginning in Fiscal Year (FY) 2019-20. SMCTA also proposed to revise the funding plan to advance project delivery with the use of $8,000,000 in local sales tax (Measure A) funds for construction support, and request reimbursements in FYs 2019-20 and 2020-21.
In January 2020, the CTC approved an AB 3090
reimbursement of $4,000,000 for PPNO 04-0690B. 04-SM-101 1.6. AB 3090

US 101 Barriers - Los Berros Road to Traffic Way (05-SLO-101 7.816/12.565)
In September 2012, construction started on on a K-rail
median barrier designed to prevent head-on collisions and plunges into
deep ravines along a 5-mile stretch of US 101 south of Arroyo Grande. The
$2.8 million barrier will run from the Los Berros Road undercrossing near
Nipomo (approx SLO 7.816) to the undercrossing where vehicles enter
southbound US 101 from Traffic Way (approx SLO 12.565). All but one of the
at-grade highway crossings through that stretch will remain open; one
crossing that serves a private driveway just south of El Campo will be
blocked by the barrier. Caltrans initiated the project in response to a
rising number of traffic collisions at the at-grade highway crossings. The
barrier is also designed to prevent vehicles from crossing the median into
oncoming traffic or plunging into ravines between the north- and
southbound lanes. As initially proposed, the barrier would have blocked
cross traffic at all of the highway crossings, including one at Laetitia
Vineyard Drive. But it was particularly aimed at closing the El Campo Road
crossing, where the accident rate had been steadily climbing. The crash
frequency at El Campo Road rose from three in 1998 to 10 in 2008,
according to Caltrans statistics released in 2010. At that time, a total
of 185 collisions resulting in three fatalities and 101 injuries had been
reported along the five-mile stretch of highway. But residents along El
Campo Road, the operators of Laetitia Vineyard & Winery and Arroyo
Grande city officials objected to closing those two crossings. People
living along El Campo Road and operators of Laetitia Vineyard & Winery
said blocking those intersections would require residents and winery
visitors and workers to drive miles out of their way. Arroyo Grande
officials said the closures also would send more traffic through the city
as drivers sought to turn around. As a result, Caltrans agreed to add
flashing yellow lights to cross-traffic warning signs and to leave all but
one of the crossings open. It appears the warning beacons may have helped,
based on Caltrans’ recent crash statistics: In the seven months
prior to installing the beacons, seven multiple-vehicle crashes were
reported along the five-mile stretch. In the first seven months after they
were installed, only one multiple-vehicle crash has occurred.

In March 2019, it was reported that the San Luis Obispo Council of Governments (SLOCOG) staff is recommending that four intersections between Los Berros Road and Traffic Way (~ SLO 7.866 to SLO 12.548) along US 101 should close. At a packed public
outreach meeting on March 21, staff discussed the results of the second
phase of the board's $30,000 two-step assessment process to understand the
implications of restricting left turns on this stretch of the highway.
Stephen Hanamaikai, transportation planner, said the study looked at the
impact of closing four intersections—El Campo Road (SLO 11.827), a
private un-named road, Tower Grove Drive (SLO 9.658), and Hemi Road (SLO
9.11)—with concrete median barriers. "The main findings were that by
eliminating those turning movements at those crossings, it would greatly
improve safety along that stretch of the 101 and reduce the possibility of
high severity collisions," Hanamaikai said. The report also stated that
the closures would only increase travel time for the surrounding community
by about two to seven minutes. Hanamaikai said staff will be taking their
findings to the April 3 SLOCOG board meeting and will recommend that the
board support the closure. The two-step assessment was initiated after
community members called for urgent short-term and long-term solutions to
El Campo Road following the death of Cal Poly student Jordan Grant. On
Oct. 7, 2018, Grant was fatally struck by a BMW that was in the process of
making an unsafe left turn at the intersection.

In April 2019, it was reported that the San Luis Obispo
Council of Governments, San Luis Obispo County’s
transportation-governing board, recommended stopping left-hand turns at
four intersections along the roadway — including El Campo Road
— to cut down on unsafe crossings in the area. The recommendation
will now go to the San Luis Obispo County Board of Supervisors for
approval at its meeting on April 23.

In May 2019, the California Department of
Transportation (Caltrans) has put a stop to the proposed project due to
recently filed legal challenge. The stoppage comes from a legal challenge
to stop the project filed in Sacramento County against Caltrans. Due to
the legal challenge, a judge filed a temporary stay until the case is
litigated completely. Caltrans says there is no timeline for when the
project will resume, if at all. But less than a week later, a judge lifted
a temporary stay of the project. That stay was put in place after Vintage
Wine Estates, which owns Laetitia Vineyard and Winery, filed a legal
challenge to stop the project. The winery business objected to the
intersection of US 101 and Tower Grove Dr., also known as Laetitia
Vineyard Dr., being included in the project and alleged that Caltrans did
not prepare an environmental impact report or provide enough notice of the
project for public review. News of Vintage Wine Estate’s legal
filing prompted the family of Jordan Grant, a Cal Poly student who was
killed in a crash at the intersection of US 101 and El Campo Rd., to call
for a boycott of Laetitia wine. After the injunction, he Grants reportedly
met with the CEO of Vintage Wine Estates and all parties agreed to work
together to improve safety along that stretch of US 101. They plan to push
for changes, including an eventual overpass at El Campo Rd., that would
increase safety while allowing access to the winery. In the meantime,
Vintage Wine Estates President Terry Wheatley said in the interest of
public safety, the Caltrans project should “move forward as soon as
possible,” and the company withdrew its legal filing. The Grants are
no longer pushing for a boycott of Laetitia, rather encouraging people to
support the business.

Brisco Road Study (approx SLO 13.752)
In September 2015, it was reported that the Brisco Road on- and off-ramps to NB US 101 were being closed as part of a traffic study. The problem was that these ramps, as well as nearby intersections, experience severe congestion at peak travel times. The notoriously congested and outdated intersection has been overwhelmed by the growth in Arroyo Grande over the past decades. The City of Arroyo Grande was investigating two project alternatives to alleviate this congestion.
In order to better understand the impacts of closing
the on and off-ramps at Brisco Road and US 101, a trial ramp closure began
on September 29, 2015 and was scheduled to last until December 2015,
although that was later extended to July 11, 2016. Traffic was to be
monitored during that time and used to improve the design plans. The city
has examined alternatives for the Brisco Road interchange since 1999, when
it identified a need to fix traffic congestion at the busy interchange.
The project has faced delay after delay as the city and Caltrans attempt
to reach an agreement on how best to update the interchange while still
maintaining the city's traffic patterns.
(Source: City of Arroyo Grande; TheTribune,
9/23/2016; KEYT, 9/29/2016)
In February 2017, it was reported that the freeway
access at Brisco Road on US 101 in Arroyo Grande was open again, and
traffic was already chaotic. What started as a five-week closure to study
traffic impacts in September 2015 was extended numerous times over the
past year as residents and council members lauded the closure, saying it
eased the notoriously bad traffic at the intersection. But it apparently
couldn’t last forever — especially after Caltrans said as much
— and the ramps were slated to reopen in mid-December 2016. The
reopening was delayed after Caltrans asked the city to add new striping on
and around the ramps, and then it was delayed even more by the Winter 2017
rains. When that exit (and entrance) was closed off, the cars flowed
easily down Branch Street (heading south) and then under the freeway on to
Brisco Road toward El Camino Real. No more cars turning right on red
lights when the opposing traffic had a green arrow; no huge traffic lines
backed all the way up the hill on Branch Street because of the odd
intersections that encompass that little area. That evidently returned
with the reopening.

The 2018 STIP, approved at the CTC March 2018 meeting, appears to show that the 2016 STIP allocated $6.624M in construction funding for PPNO 4856B Rt 101 Brisco Rd I/C improvements/Aux Lane. PM SLO 13.11/4.6. In Arroyo Grande, from Grand Avenue to Camino Mercado. Construct auxiliary lanes and interchange improvements. The purpose of the project is to provide congestion relief, alleviate queuing, and improve the traffic operations of the regional and local street system in the vicinitey of the US 101. The purpose is also to continue to accomodate accessto existing and planned development.
The 2020 STIP, approved at the CTC March 2020 meeting,

In December 2009, the CTC vacated right of way in the city of Pismo Beach along Route 101 at 0.13 mile west of North 4th Street, consisting of highway right of way no longer needed for State highway purposes (05-SLO-101-PM 15.7).
Five Cities Multimodal Transportation Network Enhancement Project (05-SLO-101, PM 16.0/R22.5)
The 2018 STIP, approved at the CTC March 2018 meeting, appears to allocate $10.337M in FY20-21 and FY22-23 for PPNO 2653 Pismo Beach, Southbound Traffic System Mangement Components.
In May 2018, the SLOCOG and Caltrans rolled out the US 101 Pismo Congestion Relief Project for public comment. Officials are
hoping the massive traffic jam from Avila Beach to Pismo Beach, can be
solved with a part-time, managed lane, stretching for four miles from
Spyglass Drive (~ SLO R19.83) to the Pismo Railroad Overhead (~ SLO
16.198). They are proposing to use the area near the center median, which
is currently grass, and convert that into a part-time lane, typically
would be used Monday through Friday between 3:00 p.m. and maybe 6:00 p.m.
Caltrans is also tossing around the idea of reconfiguring the on-and-off
ramps at Mattie Road and extending the Truck Climbing Lane near Spyglass
Drive. Officials still need to design the project along with an
environmental studies process and public review. Construction wouldn't be
completed until 2026 with an up to almost $25 million-dollar price tag.

In December 2022, the CTC approved for future
consideration of funding the following project for which a Final
Environmental Impact Report (FEIR) has been completed: US 101 in San Luis
Obispo County (05-SLO-101, PM 16.0/R22.5). Widen the inside shoulder of US 101 through Pismo Beach to provide a part-time travel lane. (PPNO
05-2653). The project is located on US 101 between postmile 16.0 and R22.5
in San Luis Obispo County. The Department proposes a seven-year pilot
project to convert the existing truck climbing lane to a general use lane
and replace inside shoulder with a part-time travel lane. The project is
fully funded and currently programmed in the 2022 State Transportation
Improvement Program (STIP) for a total of 73,615,000 which includes
Construction (capital). Construction is estimated to begin 2024-25. The
scope, as described for the preferred alternative, is consistent with the
project scope as programmed by the Commission in the 2022 STIP. Resources
in the project area that may be impacted by the project include
aesthetics, cultural resources, noise, and air quality. Potential impacts
associated with the project can all be mitigated to below significance
with the exception of aesthetics, cultural resources, noise, and air
quality, for which a Statement of Overriding Considerations was prepared.
As a result, an FEIR was prepared for the project.

(05-SLO-101, PM 16.0/R22.5). The project is located on US 101 from
postmile 16.0 to R22.5, in San Luis Obispo County. The Department proposes
to widen the inside shoulder of US 101, from San Luis Creek to the
railroad overhead in Pismo Beach, to serve as a travel lane strictly
during periods of heavy traffic volumes. At present, the California
Vehicle Code prohibits general purpose travel on the shoulder of state
highways. This project is being proposed as a pilot project, which after
seven-years in operation, the Department will pursue legislative approval
to amend the Vehicle Code, to make the part-time travel lane a permanent
feature. The project is currently programmed in the 2022 State
Transportation Improvement Program (STIP) for a total of $73,615,000 which
includes Right of Way (support and capital) and Construction (capital).

In May 2023, the CTC received notice of a forthcoming
amendment that proposes to amend the 2022 STIP to move $1,056,000 in RIP
funds from Fiscal Year 2023-24 to 2024-25 and update its title to
‘Five Cities Multimodal Transportation Network Enhancement
Project’ for the US 101 Southbound Pismo Congestion Relief project
(PPNO 2653), in San Luis Obispo County. This project is in San Luis Obispo
County, between the Pismo Overhead Railroad Bridge and the San Luis Creek
overcrossing. It will convert the existing truck climbing lane to a
general-purpose lane and replace inside shoulder with a part-time travel
lane. The purpose of the project is to improve southbound operations
on US 101 during weekday afternoon peak hours, seasonal (i.e., Summer)
peak hours, and weekend peak traffic events. In December 2014, SLOCOG
adopted its 2014 US 101 Corridor Mobility Master Plan (Corridor
Plan). The Corridor Plan identified the project area as the most
congested segment on the US 101 corridor in San Luis Obispo County. The
Corridor Plan also identified the need for better access to park-and-ride
lots. It documents extensive public outreach taking place, including
multiple local jurisdictional meetings, several workshops, and an
interactive web page. The two most frequently referenced issues were
the southbound truck lane drop near Spyglass Drive and the lack of bicycle
connectivity between downtown Pismo Beach and Five Cities Drive. A
Class I mixed-use bike path on the US 101 bridge over Pismo Creek exists
to serve bicyclists and pedestrians. In January 2015, SLOCOG and the
Department entered into a cooperative agreement to produce a Project Study
Report - Project Development Support to study six alternatives. In April
2021, the project development team identified Alternative 2 as the
preferred build option. Alternative 2 will construct a left shoulder
part-time travel lane, beginning just south of the San Luis Obispo Creek
Bridge near the Avila Beach Drive off-ramp, and convert the truck climbing
lane to a general-purpose lane. The US 101 mainline southbound lanes are
operating at or near capacity during weekday afternoon peak hours,
seasonal peak hours, and weekend peak traffic events. The mainline
southbound semi-congested to congested flow is further compounded by ramp
merge and diverge movements and by merging at the truck lane drop.
Part-time travel lanes are a Federal Highway Administration Transportation
System Management and Operations strategy that can address congestion and
system reliability issues within a right of way constrained transportation
system in a cost-effective way. A part-time travel lane is viewed as
an operational improvement project because the shoulder is converted into
a lane for general purpose travel only part time when there is demand.
During development of the Final Environmental Document, it took six months
to get concurrence from the Department’s Cultural Studies Office
along with California State Historic Preservation Officer’s approval
of the cultural/archeological components to the Environmental Impact
Report. This excessive delay in review times was due to these two State
offices being severely understaffed. This delay has caused the need to
shift construction to 2024-25. In June 2023, the CTC approved the
STIP amendment.

In July 2023, it was reported that the San Luis Obispo
Council of Governments received a $65 million grant from the California
Transportation Commission to fund the Five Cities Multimodal
Transportation Network Enhancement Project. The primary focus is adding a
travel lane on the southbound side. That added lane would run north of the
Avila Beach Drive offramp and to near Price Street, extending for about
four and a half miles. The lane would only be open from 2pm. to 7pm but
that would change if other highway closures impact traffic on US 101.
Outside of those hours, there's a partnership with Caltrans and CHP to
enforce the prohibition of use outside of that 2pm to 7pm time period. The
$65 million grant will also fund a mobility hub that will feature an
electric vehicle charging station and transit stop, and a shared-use bike
and pedestrian path in Shell Beach. The main project—the expansion
of southbound US 101—is in the middle of the design phase and
construction is expected to start in January 2025. Construction is
expected to take one year and drivers should expect road closures during
that time. The total cost of the project is estimated at 85 million.

In December 2011, the CTC approved for future consideration of funding a project in San Luis Obispo County that will widen the Los Osos Valley Road overcrossing (~ SLO 25.928) and the adjacent bridge crossing over San Luis Obispo Creek in the city of San Luis Obispo. The project is programmed in the 2010 State Transportation Improvement Program (STIP) and includes local funds. The total estimated project cost is $19,584,000 for capital and support. Construction is estimated to begin in Fiscal Year 2014-15. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2010 STIP. A copy of the MND has been provided to Commission staff. The project will mitigate potential impacts to biological, paleontological, and cultural resources and impacts to aesthetics, water quality, noise, and air quality to a less than significant level. Potential impacts to biological resources in the project area will be mitigated in accordance with the Biological Opinion rendered by the U.S. Fish and Wildlife Service. Potential impacts to paleontological resources will be mitigated by implementing a paleontological resource plan. Potential impacts to water quality will be mitigated through implementing BMPs and a storm water pollution prevention plan. Potential noise impacts will be mitigated by including construction sound control measures and limiting night work. Potential impacts to aesthetics will be mitigated by implementing a lighting plan and a landscape plan. Potential impacts to cultural resources will be mitigated by stop work requirements if a cultural resource is found.

PPNO 2831 Prado Rd Overcrossing and NB Ramp Improvmnt, ~ PM SLO 26.851
The 2018 STIP, approved at the CTC March 2018 meeting, appears to allocate $6M in FY20-21 for construction on PPNO 2831 Prado Rd Overcrossing and NB Ramp Improvmnt, ~ PM SLO 26.851.
The 2020 STIP, approved at the CTC March 2020 meeting,
adjusted the responsible organization and programming for this, so it is
now under SLO County with the title "Rt 101/Prado Rd O/C and NB Ramp,
improvmnts". The programmed funding has shifted from FY20-21 to FY21-22.

The Cuesta Grade is a 7% grade around Cuesta Peak into San Luis Obispo (~ SLO 35.132). It was the site of a major construction project on US 101. This project added truck climbing lanes, improving drainage, stabilizing retaining walls, and widening shoulders, and was the third major reconstruction of the grade. The first one, in 1937, reduced the number of curves along the route from 71 to 12; the second one, in 1990-91, focused on the northern approach to the Grade.
In December 2011, the CTC also approved for future consideration of funding a project in San Luis Obispo County on US 101 that will build a concrete median barrier, remove the existing metal-beam guardrail and temporary railing, and replace the sand-filled barrel array with a crash-cushion system. The project will also extend the existing southbound left-turn lane and add northbound and southbound acceleration lanes at the intersection of US 101 and Tassajara Creek Road (~ SLO 36.8). The project is programmed in the 2010 State Highway Operation and Protection Program (SHOPP). The total estimated cost is $6,988,000. Construction is estimated to begin in Fiscal Year 2012/13. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2010 SHOPP. A copy of the MND has been provided to Commission staff. The project will mitigate potential impacts to biological resources and aesthetics to a less than significant level. Potential impacts to biological resources will be mitigated through the use of ESA fencing and the use of Caltrans standard bird protection specifications. In addition, median barrier openings will be placed to reduce animal entrapment on the highway. Potential impacts to aesthetics will be mitigated by implementing a landscape plan for the project.
In September 2014, an Assembly Concurrent Resolution (ACR 145, Resolution Chapter 175, 9/11/2014) directed Caltrans to determine the cost of erecting signs at the Route 41 intersection (~ SLO 45.569) to the Faces of Freedom Veterans Memorial. The memorial is the result of the efforts of the Atascadero Veterans Memorial Foundation, created in April 2006, with a goal of building a world class veterans memorial on the California central coast.
In December 2004, the CTC considered a resolution to relinquish right of way in the City of Atascadero, at San Ramon Road (5-SLO-101-PM 49.3), consisting of reconstructed and relocated city streets and frontage roads. The City, by cooperative agreement dated July 27, 2004, waived the 90-day notice requirement and agreed to accept title upon relinquishment by the State.

improvements at the US 101 / Route 46 interchange, in San Luis Obispo
County. (MND and MND Addendum) (PPNO 2559) (STIP). The project is located
on US 101 at postmile 53.8 to postmile 54.5, and Route 46 at postmile
R21.5 to postmile R22.0, in San Luis Obispo County. The Department
proposes to improve the US 101/Route 46 west interchange. The project is
currently programmed in the 2020 STIP for a total of $19,109,000, which
includes $1,300,000 for the Plans, Specifications, and Estimates phase.
Construction began in 2020-21 The scope, as described for the preferred
alternative, is consistent with the project scope as programmed by the
Commission in the 2020 STIP. A copy of the MND and Addendum has been
provided to Commission staff. The project will result in less than
significant impacts to the environment after mitigation. The following
resource areas may be impacted by the project: aesthetic and biological
resources. Avoidance, minimization, and mitigation measures will reduce
any potential effects to the environment. These measures include, but are
not limited to, implementing a landscape and revegetation plan to address
affected oak trees and vegetation replanting or removal, replanting oak
trees at a 10:1 ratio, limiting project lighting to minimize light and
glare impacts, and aesthetic treatments to the wall along the south side
of SR 46 West and the retaining wall associated with the existing
drainage. As a result, a MND and addendum was completed for this project.
An Addendum was prepared to address changes in new regulations concerning
project analysis of air quality, energy, noise, traffic, and biology
(wetland jurisdiction requirements; as well as the status of listed
species). The project also incorporated a revised roundabout design, which
will create a modified Type L-1 interchange with two
single-circulating-lane roundabouts at the ramp intersections. The reduced
footprint of the revised project resulted in a smaller disturbance area
and will require less property acquisition than the original project
design. The Department subsequently completed an Addendum to the MND
pursuant to CEQA.

Route 46 Intersection Improvements (05-SLO-101 56.8/57.9)
In July 2010, the CTC approved for future consideration of funding a project that will construct roadway improvements including intersection improvements and lane additions in the city of Paso Robles near the intersection with Route 46 (~ SLO 57.895). The project is programmed in the 2010 State Transportation Improvement Program and includes local funds. Construction is estimated to begin in Fiscal Year 2010-11. Total estimated project cost is $14,060,000 for capital and support. Specifically, the City of El Paso de Robles and the San Luis Obispo Council of Governments (SLOCOG) in cooperation with Caltrans are working on a project to provide operational and access improvements along US 101 and at the US 101/Route 46 E interchange within the limits of the City of El Paso de Robles. The proposed project improvements include the relocation of the existing isolated 16th Street southbound US 101 off-ramp to 17th Street (~ SLO 57.158) and the construction of a new 17th Street southbound US 101 on-ramp, creating a new public road access to US 101. This new connection, just south of the US 101/Route 46 E interchange, will help reduce congestion and decrease delays on the local street grid and improve operations on the US 101/Route 46 E interchange. At the US 101/Route 46 E interchange Route 46 E is a four-lane expressway and US 101 is a four-lane freeway facility. Improvements to alleviate congestion for the westbound Route 46 to southbound US 101 left turn movement are needed since ramp capacity is often exceeded during the peak hours. The excess demand causes a traffic queue past the northbound US 101 off-ramp intersection and into the westbound Route 46 E through lane. In order to provide additional capacity to the southbound US 101 on-ramp, the proposed project includes re-striping on Route 46 E and widening of the on-ramp to provide dual left turn movement onto southbound US 101 from westbound Route 46 E. To avoid weaving problems along this section of US 101, the project also includes the construction of an auxiliary lane on southbound US 101 from Route 46 to the new proposed exit ramp at 17th Street. The 16th Street exit ramp is an isolated single lane exit ramp that has two separate connections to Riverside Avenue approximately 210-feet apart. These two separate connections can result in driver confusion and the potential for wrong way movements. The limited freeway connections within the Route 46 corridor along US 101 contribute to greater congestion and longer delays on the local street grid. Relocating the existing exit ramp to the 17th Street/Riverside Avenue intersection accommodates the addition of an entrance ramp to southbound US 101 and improves the existing isolated exit ramp condition while relieving congestion on the local street system.
In May 2023, the CTC approved the following allocation
for a locally-administered STIP project: $1,547,000. 05-SLO-101 56.8/57.9.

Wellsona Road Interchange / Paso Robles (~ SLO 61.888)
In November 2016, concern was expressed about the
Wellsona Road interchange N of Paso Robles. There have been 16 crashes at
the intersection since 2012, 12 of which have resulted in injuries or
fatalities, according to CHP data. Many of the crashes involved drivers
crossing the road too soon, leaving them exposed to traffic traveling
about 65 mph. Over the years, residents have pushed for changes at the
intersection, where a truck stop and an RV park attract slower-moving
vehicles and give drivers additional reasons to cross in front of highway
traffic. Caltrans representatives, traffic engineers and local officials
say solutions aren’t as clear-cut as they might seem. Anurag Pande,
an associate professor at Cal Poly’s College of Engineering, said
the setup of the intersection and the nature of US 101 make quick,
substantial fixes nearly impossible. At this spot, US 101 is no longer a
freeway, which means intersections replace overpasses and on- and
off-ramps. To drivers, the road appears clear and open and no different
from the adjacent stretches to the north and south. This conditions
drivers to expect they will be able to maintain a consistent, fast rate of
speed. The solution would be to build an overpass, but Ron De Carli,
executive director of the San Luis Obispo Council of Governments, said
“the project is needed,” but building such a structure would
cost about $30 million, money San Luis Obispo County doesn’t have.
Further, the Wellsona intersection isn’t the highest priority for
San Luis Obispo County roadway fixes. Other projects, including those to
alleviate traffic congestion on US 101 near Pismo Beach and on Route 227
near San Luis Obispo, are much closer toward the top of the list of local
needs. An average of 70,000 vehicles per day drive past Pismo Beach, while
15,000 travel through the Wellsona intersection. Caltrans is planning some
upgrades it says it hopes will reduce the frequency of crashes at the
intersection. Caltrans District 5 spokesman Jim Shivers wrote in an email
that the agency plans to make improvements to the intersection by the end
of 2016 or early 2017, including roadside lights, truck-crossing signs
with flashing beacons and redone striping in a 2-mile area on both sides
of the road.
(Source: SLO Tribune, 11/19/2016)
In October 2017, it was reported that Caltrans is
planning an underpass near Wellsona Road and US 101 — located just
north of Paso Robles and just south of San Miguel — where grape grower Richard Sauret was killed on 10/1/2017 when his truck collided with a southbound vehicle while he was turning left. The $13 million underpass
will be located just south of the intersection, and will be funded by the
State Highway Operation and Protection Program, said Jim Shivers, a
spokesman for Caltrans District 5. Caltrans informed San Luis Obispo
County officials of the plan in an August 2017 letter. A median will be
installed on US 101 in the middle of the intersection, and all left turns
will be eliminated. Construction on the underpass is expected to begin by
2022, although there’s no current timeline for the project and
funding has not yet been secured. The San Paso Truck Stop and the Vines RV
Resort on either side of the road mean slow, heavy vehicles frequently
cross the highway in front of traffic, increasing the risk of high-speed
collisions. In 2016, Ron De Carli, executive director of the San Luis
Obispo Council of Governments, estiamted that building an overpass would
cost about $30 million. [Note: There's an interesting implication here: to
construct an underpass, as opposed to an overpass, means the highway must
be closed for the excavation; this means there will be a temporary detour
of US 101 to the side frontage roads for the duration of construction.]
(Source: SLO Tribune, 10/16/2017)
In July 2018, it was reported that the San Luis Obispo
County Board of Supervisors allowed plans for the Paso Robles Truck Center
— slated for vacant property near the intersection of Wellsona Road
and US 101 — to continue without expensive road improvements
requested by Caltrans. The Wellsona Road intersection between Paso Robles
and San Miguel is among the most notorious in the county, along with the
Cholame “Y” Route 41-Route 46 interchange to the east. More
than 20 collisions have occurred within 30 feet of the intersection since
2011, according to the CHP. Four of these collisions resulted in seven
fatalities. To combat wrecks, Caltrans plans to build a $13 million
underpass just south of the intersection, which will allow vehicles to
exit US 101 using ramps instead of an at-grade intersection. Construction
is expected to begin in 2022 and wrap up by 2024. In the meantime, Steve
Ormonde — who previously operated a truck-repair facility on Golden
Hills Road in Paso Robles — is seeking the go-ahead to build the
Paso Robles Truck Center just north of the San Paso Truck Stop. The
25,000-square-foot facility has been in the works since 2014, but
negotiations with Caltrans over road improvements have slowed the approval
process. The Board of Supervisors voted 4-1 to allow the project to move
forward — even without extending a northbound acceleration lane,
which allows trucks turning left from Wellsona Road onto US 101 more time
to merge onto the road. The intersection has a limit of 2,300 trips per
day before infrastructure improvements are required. The new facility
would add 304 new trips, bringing the total to 2,206 trips. Extending the
lane would likely cost about $200,000, a large expense for an improvement
that won’t be needed when Caltrans finishes the underpass in six
years.

South Salinas Corridor Project 05-MON-101-PM 77.0/85.6.
This project is one of the
projects under consideration for the funds received from sale of the ROW
purchased for the freeway routing of the Prunedale Bypass, the adoption of
which was undone in June 2021. The project (EA 05-0H330 ProjID 0513000133)
proposes to improve safety and relieve future traffic congestion by
eliminating multiple highway crossings, constructing a new interchange at
Harris Road and providing necessary frontage roads to allow farmers to
access their lands. Includes frontage roads along US 101 South of Salinas
(Abbott Street on/off ramp) and related intersection improvements. This
segment of US 101 is currently a four-lane expressway with an inadequate
frontage road system with twelve at-grade intersections and numerous
private driveways within the project limits. The project study
area and surrounding areas have experienced a substantial amount of
development, which is expected to continue in the future. This
continued growth, coupled with a growth in commute and interregional
traffic, has resulted in substantial congestion. In addition to the
congestion, safety is also a concern. There is a lack of controlled access
along the corridor which results in conflicts between fast moving through
traffic and slower moving vehicles, such as agricultural vehicles, which
turn off and onto the expressway. Cost Range: $112,000,000 to
$250,000,000.

According to the Monterey COG, this project will construct frontage roads along US‐101 south of Salinas (Abbott Street on/off‐ramp, ~ MON 84.409) and make related intersection improvements. Traffic on US 101 in South County is increasingly impacting the highway as well as adjoining interchanges. The lack of frontage roads means that agricultural trucks must use the highway to make local trips, adding to traffic congestion and forcing U‐turns and other tricky maneuvers on US 101. Antiquated interchanges all along US 101 will not be able to accommodate traffic in the near future. The purpose of this project is to improve safety and relieve future traffic congestion by eliminating multiple highway crossings while providing the necessary frontage roads to allow farmers access to their lands.
In March 2020, the CTC approved the 2020 STIP, which
adjusted the programmed funding for PPNO 3300 "South County Freeway
Conversions" from $21,169K to 8,611K, and changed the title to "So Co
Freeway Conversions, Main St-Airport Blvd", which would be MON 85.679
(Airport Blvd) to MON R88.243 (Main St)

In January 2023, it was reported that the
Transportation Agency for Monterey County (TAMC) announced that the
Federal Highway Administration has earmarked $1 million for the “US 101 Auxiliary Lane – South of Salinas” project. The earmark,
sponsored by Congressman Jimmy Panetta and Sen. Alex Padilla, is included
in the Consolidated Appropriations Act for Fiscal Year 2023. The
project will extend the US 101 northbound acceleration lane at Spence
Road. Construction should start in 2023. The project is expected to be
completed in 2024. The acceleration lane is an initial safety improvement
in the overall “US 101 South of Salinas” project, which
proposes to address safety concerns and improve traffic flow along 5.5
miles of US 101, from Airport Boulevard to the Main Street over-crossing
in Chualar. The auxiliary lane will provide space for trucks to safely
accelerate from Spence Road onto US 101 and provide a deceleration lane
for traffic exiting to Eckhardt Road. The “US 101 South of
Salinas” project is a Measure X funded project with $30 million
allocated to it, and is identified in the countywide “Transportation
Safety and Investment Plan” approved by Monterey County voters in
2016. Of a total construction cost of $3,247,000 for the auxiliary lane,
$317,000 of Measure X is leveraging $1.93 million of state funding in
addition to the $1 million federal earmark.

In June 2014, the CTC approved for future consideration of funding a project located at the juncture of US 101 and Sanborn Road (~ MON 86.139) in the southern portion of the City of Salinas in Monterey County. The project will construct a series of improvements to address operational traffic and circulation issues at this interchange. Project components include: extending the raised median of Sanborn Road to preclude left turns at Elvee Drive, improving the right-turn lane on westbound Sanborn Road to Work Street, extending Elvee Drive to Work Street, constructing a new bridge at the existing Monterey County Water Resources Agency (MCWRA) Reclamation Ditch crossing, signalizing the Sanborn Road/Northbound loop off-ramp/Fairview Avenue intersection, constructing a ramp meter on the Northbound US 101 on-ramp from Fairview Avenue, widening Elvee Drive and reconstructing/rehabilitating its existing pavement to handle truck traffic, installing curb, gutter, sidewalk, and street lighting along Elvee Drive, and planting approximately 50 trees.

In January 2017, the CTC authorized relinquishment of right of way in the county of Monterey along Route 101 between Russell Road and Echo Valley Road (05-Mon-101 PM R91.6/98.8), consisting of superseded highway and collateral facilities. The County, by freeway agreement dated August 28, 2007 agreed to accept title upon relinquishment by the State. The 90-day notice period expired November 23, 2016.
Prunedale Bypass/Prunedale Freeway (~ MON R91.886 to ~ MON 98.377)
There were once plans for a "Prunedale Freeway" to provide an alternative to the safety
and capacity problems that exist on the current route, which serves as the
"Main Street" of the Prundale urbanized area north of Salinas. In November
2000, Caltrans narrowed the field of alternatives to the following
(construction planned for 2007):
As of February 2004, it appears that Alternative 4 East (the new-terrain routing from Espinosa Road/Russell Road in Salinas north to near Echo Valley Road in Prunedale) has been chosen. As a result, it is likely that the US 101/Route 156 expressway between the south Route 156/US 101 interchange and Echo Valley Road will become solely Route 156. There is no info as to what the southern portion of the El Camino Real expressway from Espinosa Road to Route 156 will be.
There is also an unconstructed-adopted segment from Salinas to Route 156; 12 miles parallel to the traversable route. When (if ever) completed, this portion of US 101 will become Route 156.
Preliminary roadwork on the 13-mile Prunedale
Improvement Project (PIP) began on Monday, Feb. 14, 2011; the work
includes removal of some trees near Espinosa and Russell Roads in Salinas
(see below). The PIP addresses traffic safety issues along US 101, from
Espinosa/Russell Roads in Salinas north to Crazy Horse Canyon/Echo Valley
Roads. The project includes construction of three new interchanges
/overpasses and a continuous median barrier from Crazy Horse Canyon to
Russell/Espinosa. These safety measures will eliminate dangerous left
turns, reduce delays on US 101, provide safer access for local business
and residents and provide congestion relief for the thousands of vehicles
that travel through the corridor every day. The contract for construction
on the PIP was awarded to Granite Construction Company and MCM
Construction, a joint venture from Watsonville, on Jan. 25. Major roadwork
is scheduled to begin in the spring and be completed in late 2014. The
project was actually completed in January 2016, with the completion of the
the San Juan Road Interchange Project.

In October 2017, there was an update regarding the Prunedale Freeway, which evidently
never happened. Back when the bypass seemed like a good idea,
well-intentioned locals did what they could to make the bypass a reality.
They occasionally chartered and filled buses bound for Sacramento so that
Monterey County would be duly represented at key transportation committee
hearings. A part-time lobbyist was contracted to do Monterey
County’s bidding. Eventually, the state declared that Monterey
County and other rural counties could compete with the big urban counties
if they could show a willingness to put their own money where their needs
were. If Monterey County could prove that its citizens were willing to pay
a “fair share” to build the bypass, the state would pony up
the rest. The formula is referred to as being a “self-help”
county. What followed was a series of local ballot measures — four
of them, in all — asking voters in Monterey County to impose tax
increases on themselves to help pay for a package of
roads-and-transportation projects. The Prunedale Bypass was always a star
attraction for those measures. The first of those ballot initiatives,
Measure B, was approved by voters in 1989. It was considered a signature
achievement — a tax increase approved by taxpayers. County officials
started collecting millions of dollars in additional sales tax, and they
set it all aside for highway projects like the bypass. But the vote was
eventually ruled unconstitutional. County officials thought they needed a
simple majority to pass the tax increase, when in fact the measure
required 67 percent of the vote. To its embarrassment, the county was
forced to reimburse county residents in an awkward and cumbersome process.
When it became evident the money would never come, transportation
officials gave up on the bypass. They went with Plan B, completed in 2015.
This was the "Improve Existing Alignment" option. The results of Plan B
are what motorists see now when traveling along US 101 through Prunedale.
Interchanges were built and side-road access points were simply sealed
off. That alternative was cheaper by at least half.
(Source: Voices of Monterey Bay, 10/15/2017)
So what of the land acquired for the bypass? After all,
the state had acquired hundreds of acres of right-of-way for the bypass.
In particular, with the bypass a dead deal, the state needed to dispose of
353 acres of old right-of-way property. A law was proposed that would have
insured that any money the state earns by selling the land — maybe
up to $10 million — would be used for other highway projects in
Monterey County, However, the governor vetoed that bill, using the funds
to pay off transportation bonds.

In December 2019, the CTC had on its agenda a Notice of
Intent to Consider Rescinding Freeway Adoption Resolution NIU 19-01 and
map authorizing a rescission of a portion of the freeway adoption for US 101 in the Counties of Monterey and San Benito. What this would do is
rescind a portion of the 1964 Route Adoption for the unconstructed freeway
alignment between Espinosa Road and Route 156 in Monterey and San Benito
Counties. The TAMC, SBCOG, and San Benito County have confirmed the
adopted route is no longer part of any local or regional plans and it is
appropriate for the Department to rescind the unconstructed portion of the
freeway alignment. Once the route rescission is approved, the
Department’s responsibility is to dispose of the excess land.
Deficiencies on US 101 in the Prunedale area were recognized in the 1960s
when a project was initiated to improve the corridor by constructing a new
alignment that bypassed the community of Prunedale. On June 15, 1964, the
Department’s State Highway Engineer made a recommendation to the
California Highway Commission (CHC) to adopt the US 101 freeway route. The
Route Adoption was passed by the CHC resolution on June 24, 1964. In April
1973, the Prunedale Bypass Project (PBP) was in the final design phase
when it was determined that federal funding could not be secured, and the
project was delayed indefinitely. In the late 1980s, the PBP was
re-initiated from a Measure B sales tax but was challenged and overturned
in court and lack of funding again halted the PBP. As a result, in 2015,
the Prunedale Improvement Project (PIP) completed a series of operational
and safety improvements such as upgrading the existing four-lane facility
to partially access controlled with construction of ten miles of median
barrier, two new interchanges, and an overcrossing. The PIP was considered
to be Phase 1 of conversion to a full access controlled freeway. Phase 2
was envisioned as the Prunedale Freeway on either the existing alignment
or on the 1964 adopted bypass alignment. As of 2019, the Phase 2 project
is no longer identified in the TAMC Regional Transportation Plan.
Similarly, for San Benito County, there are no local or regional planning
studies existing or underway that would have a bearing on existing route
adoption. Ultimately, there is little likelihood for any construction to
occur on the unconstructed portions of the adopted route from the affected
agencies; therefore, rescission is appropriate. Rescission of the
unconstructed freeway adoption for US 101 from Espinosa Road to Route 156
from the State Highway System will allow the sale of excess lands. The
unneeded right-of-way will make available excess land allowing for further
community development, promoting economic growth, and relieving the
Department from ongoing maintenance costs, including weed abatement and
public dumping, and liability concerns. In March 2020, it appears the item
from December 2019 concerning rescission of 05-Mon-101 PM R91.9/101.3,
05-SBt-101 PM 0.0/2.9 was again on the agenda.

In June 2021, the CTC approved recission of the
following freeway adoption: 05-Mon-101 PM R91.9/101.3 05-SBt-101 PM
0.0/2.9. A portion of US 101 from Espinosa Road to Route 156 in the
counties of Monterey and San Benito. The rescission of the unconstructed
freeway adoption for US 101 from Espinosa Road to Route 156 from the State
Highway System will allow the sale of excess land purchased for the
Prunedale Bypass. Monterey County has requested proceeds from the
sales of the excess land to be diverted to Monterey County’s local
alternative transportation improvement program (LATIP), per State of
California Government Code 14528.8. The two projects identified are as
follows:

Russell/Espinosa Road Interchange (Part of the Prunedale Improvement Project) (~ MON 92.193)
In November 2007, the CTC considered the addition of a public road connection to US 101 at Sala Road
(~ MON 92.193). This new interchange will essentially replace an existing
at grade connection located to the south at Russell/Espinosa Roads and it
is expected to improve both safety and operations on US 101. The Russell
Road/Espinosa Road connection currently has a collision rate higher than
the statewide average for similar facilities. The project is expected to
be open to traffic in the Fall of 2012. Specifically, in the vicinity of
Russell and Espinosa Roads, the plan is to construct a new section of
access controlled four-lane freeway from 0.2 miles north of the Boronda
Road interchange to approximately Martines Road. The alignment of US 101
would be elevated to accommodate modifications to the existing at grade
connection of Russell and Espinosa Roads. Undercrossing structures would
be constructed to facilitate the connection of Russell and Espinosa Roads
to enhance local circulation. Since no freeway access would be allowed at
this location, a new interchange at Sala Road will be needed. This segment
of mainline US 101 would be constructed primarily to standard freeway
geometrics except where it conforms to existing conditions at the northern
end of the segment. Design exceptions for all nonstandard features have
been approved. Median width would range from 21 to 70 feet and median
barrier would be constructed from the undercrossing structure at Russell
and Espinosa Roads to existing concrete median barrier at Martines Road. A
new interchange and local road, Sala Road, would be constructed
approximately 0.62 miles north of Russell/Espinosa Road. To facilitate
merge/diverge traffic movements, auxiliary lanes would be constructed
along the new freeway segment between the northern ramps at the Boronda
Road interchange and this new interchange. The new interchange at Sala
Road would connect to Harrison Road to the east via Sala Road. The
interchange would consist of three directional ramps and a westbound to
southbound loop-ramp. No ramp would be constructed in the southwest
quadrant. Initially, the overcrossing structure would accommodate two
lanes with left-turn channelization. However, the structure would be
constructed with consideration for the future widening to four lanes with
left turn channelization.
Route 156 West Corridor/Castroville Blvd Interchange (05-Mon-101, PM 94.6/96.8 05-Mon-156, PM R1.6/T5.2)
The 2018 STIP, approved at the CTC March 2018 meeting, appears to allocate $19,800K for
the Castroville Blvd Interchange (~ MON R1.819). The Monterey COG
described the project as build a new interchange at Castroville Boulevard
and Route 156, with connections to Blackie Road to improve access for
commercial traffic. There is a related project, also funded in the STIP,
that extends Blackie Road to connect to a new interchange at Route 156 and
Castroville Boulevard. The COG notes that Route 156 at Castroville
Boulevard is the top collision location in Monterey County. In addition,
Route 156 is the major link connecting the San Francisco Bay area and
North Monterey County to the Monterey Peninsula. With its present narrow
configuration, it currently operates over capacity, with substantial
delays and safety concerns, particularly during special events on the
Monterey Peninsula. This congestion affects travel to and from the
Peninsula as well as travel between US 101 and Route 1 for local
residents. In addition, the traffic impedes access to the Oak Hills
neighborhood. This project will direct truck traffic away from Merritt
Street in Castroville and from the accident‐ridden Route 183/Route 156 interchange. It will also help relieve traffic congestion on Route 156
while improving safety and local traffic circulation in North Monterey
County. The extension of Blackie Road provides traffic congestion relief
and improves safety for Oak Hills and other local communities.
In April 2018, it was reported that a new interchange
is being pursued at Castroville Boulevard and Route 156, where there is
currently a stop light. An interchange would end t-bone accidents,
rear-end collisions and make it safer by getting trucks out of
Castroville, with a new Route 156 connection to Blackie Road. This could
take five years.

In March 2020, the CTC approved the 2020 STIP, which

Boulevard Interchange. Route 156 in Monterey County at Castroville
Boulevard from Post Mile R1.6 to 1.4. Build a new interchange at
Castroville Boulevard and Route 156. The project scope requires the
acquisition of 15 parcels and extensive offsite environmental
mitigation and utilities. The signalized intersection at Castroville
Boulevard and Route 156 is the only signal along the route west of
US 101. Because of that, drivers may be unprepared for traffic that has
completely stopped due to a red signal. The accident rate at the
Castroville Boulevard intersection on Route 156 is over twice the
rate of what would be expected of a similar intersection in
California. Additionally, the frequent stoppage of traffic due to the
signal causes congestion. Traffic has been known to back-up in both
directions for miles during the Summer and for weekend events on the
peninsula.

In December 2020, it was reported that the first phase
of the long-awaited Route 156 corridor improvement project was fully
funded and ready for construction after being approved for $20 million in
state gas tax funding by the California Transportation Commission.
According to the Transportation Agency for Monterey County, the state
transportation commission gave the thumbs to allocating SB 1 trade
corridor enhancement program funds for the $55.2 million Castroville
Boulevard interchange project. The funding was part of a $2 billion
package approved for 56 projects across the state aimed at federally
designated trade corridors of national and regional significance with a
“high volume of freight movement” such as Route 156, which
supports the county’s $4.4 billion-per-year agricultural industry by
serving a key route for truck traffic. The state funding means the
Castroville Boulevard interchange project now has the entire $29.5 million
needed to move forward with construction in the next two years. It is part
of the overall $380 million Route 156 improvement project that includes a
proposed $75 million four-lane expressway between the new Castroville
Boulevard interchange and US 101 in Prunedale, and a new $250 million
interchange at Route 156 and US 101. The project includes constructing a
new Castroville Boulevard interchange including an overpass and three
roundabouts to the east of the existing four-way stoplight and expanding
the highway to four lanes from the stoplight intersection to the new
location. It will be constructed to operate in conjunction with both the
current highway route and the proposed four-lane expressway. In addition
to the $20 million in state SB 1 funding, the interchange project is being
funded by about $27.7 million in state Transportation Improvement Program
funding, $5 million in developer fees and $2.25 million in voter-approved
Measure X funding. The project was originally slated to receive $30
million in Measure X funding but Hale said the state funding allowed
Transportation Agency for Monterey County to redirect those funds to the
Blackie Road extension, which would connect Castroville’s industrial
area to the new Castroville Boulevard interchange and allow truck traffic
to avoid Route 183 through downtown Castroville and the interchange at US 101 and Route 183.

In June 2021, it was reported that
this project is one of the projects under consideration for the funds
received from sale of the ROW purchased for the freeway routing of the
Prunedale Bypass, the adoption of which was undone in June 2021. This
project (EA 05-31600, ProjID 0500000497) proposes to remove and
reconstruct the current interchange. The new interchange
configuration will include a fully functioning interchange and a new
flyover structure which will connect eastbound Route 156 traffic to
northbound US 101. This project also proposes to convert US 101 from
a four-lane expressway to a four-lane freeway within the project
limits. This segment of US 101 experiences congestion in both the
northbound and southbound directions on a regular basis, especially on
weekends. Heavy weekend traffic is generated by tourism from the Bay
Area to the Monterey Peninsula and Big Sur. There are safety
concerns and operational deficiencies due to poor weaving distances and
at-grade intersections. The operational deficiencies exacerbate the
congestion problems. The project proposes to improve safety and address
numerous operational deficiencies on US 101 by improving weaving
distances, removing at-grade intersections, and constructing a new
frontage road. Cost Range: $300,000,000 to $425,000,000.

In December 2021, there was an update on the status of
this project: A planned westbound connector at the intersection of Route 156 and US 101 will extend the current onramp an additional 1,800 feet and

to determine the size and cost of the project.

In May 2023, it was reported that the Transportation
Agency for Monterey County announced that the Route 156/Castroville
Boulevard project is not expected to be ready to list by the June 30 2023
funding deadline. Ready to list means a project has met certain criteria
by the time funding is allocated. The project, which was approved under
Monterey Counties Measure X in 2016, is being held up by PG&E utility
relocation work that will not be completed until December. Now, to make
sure the project avoids losing funding, the California Transportation
Commission is calling for at-risk funding allocation. This funding would
be conditional and would only go through if Caltrans got approval to
develop the land from PG&E. The project has been in the works for more
than a decade. It would get rid of the only traffic light on Route 156 and
replace it with a roundabout. The project was originally expected to cost
$29.5 million, with funding coming from both state and local sources. Now,
that price tag has ballooned by $18 million and is estimated to cost $47.5
million. The TAMC has proposed that the additional funding come from
additional Measure X funds and California's Trade Corridor Enhancement
Program. In their June meeting, the California Transportation Commission
approved an environmental impact report for the project. A 12-month time
extension was also approved to request the $20 million Trade Corridor
Enhancement Program funding. The extension provides time for PG&E to
complete the utility relocation work and for Caltrans to finish
right-of-way certification.

In June 2023, the CTC had on its agenda the following
project, which was deleted from the agenda before the meeting: 05-Mon-101,
PM 94.6/96.8 05-Mon-156, PM R1.6/T5.2. Route 156 West Corridor.
Widen Route 156 between US 101 and Castroville Boulevard and rebuild the
US 101/Route 156 interchange, in Monterey County. (FEIR Addendum) (PPNO
0057D) (TCEP) (STIP). The project is located on US 101 from postmile
94.6 to postmile 96.8 and SR 156 from postmile R1.6 to postmile T5.2, in
Monterey County. The Department proposes to widen Route 156 from 2 lanes
to 4 lanes and convert US 101 from an expressway to a freeway. The
project is currently programmed in the 2020 State Transportation
Improvement Program (STIP) and Transportation Corridor Enhancement
Program (TCEP) for a total of $13,294,000 which includes Right of Way
(Capital) and Construction (Capital). Construction is estimated to begin
in 2024-25. The scope, as described for the preferred alternative, is
consistent with the project scope as programmed by the Commission in the
2020 STIP/TCEP. A copy of the FEIR has been provided to Commission
staff. The Commission approved the project for future consideration of
funding on August 6, 2013, under Resolution E-13-65. The project has
been divided into three segments and various design modifications have
been made such as shifting the alignment of SR 156 West southward to
accommodate the new design of the grade-separated interchange and the
acquisition of approximately 9.79 acres of additional property. The new
alignment would result in additional impacts to jurisdictional waters
and wetlands. Additionally, after further coordination with CDFW, it was
determined that habitat for California tiger salamander and Santa Cruz
long-toed salamander would be impacted by the project. As a result,
additional avoidance, minimization, and mitigation measures were added
to the project. The Department subsequently completed an Addendum to the
FEIR pursuant to CEQA. The Department has approved this project for
construction. This approval and the Addendum will satisfy the
environmental requirements for this stage of the planning process.

and refinements to impacts and mitigation associated with the following
resources: natural communities and habitats, jurisdictional waters,
biological species, visual/aesthetics, and noise. The project would not
result in substantial increases in the severity of significant effects,
would not involve substantial changes in regulatory circumstances, did not
identify new alternatives, and proposed similar avoidance, minimization,
and mitigation measures when compared to the 2013 FEIR. The project
changes do not meet the criteria outlined in CEQA Guidelines Section 15162
and Section 15163 to prepare a Subsequent or Supplemental FEIR. The
Department subsequently completed an Addendum to the FEIR pursuant to
CEQA. The Department has approved this project for construction. This
approval and the Addendum will satisfy the environmental requirements for
this stage of the planning process.

San Juan Road Improvements (Part of the Prunedale Improvement Project) (MON PM 100.0/101.3)
In April 2006, the CTC received the notice of the preparation of an Environmental Impact Report for construction of a new interchange near San Juan Bautista in Monterey County (PM 100.0/101.3). The project is currently programmed as “environmental only.” The following alternatives are being considered: (·) Alternative 1A: Spread Diamond Interchange – Located approximately midway between Dunbarton Road to the south and San Juan Road to the north; (·) Alternative 1B: Compact Diamond Interchange – Same location as Alternative 1A, with interchange ramps and frontage road closer to alignment of highway; (·) Alternative 2: Compact Diamond Interchange – Located near the San Juan Road/ Route 101 intersection, with frontage road on east side of Route 101; (·) Alternatives 4, 5, 9A and 9B: Same general location as Alternative 2, with variations on the interchange configuration and the frontage road alignment; (·) No Build. The potential impacts include floodplain encroachment, drainage, hazardous waste, and visual impacts. Proposed mitigations include avoidance of service station acquisition, visual resource mitigation, and new alternative north of the floodplain and Elkhorn Slough.
In 2007, the following requests for funding from the Corridor Mobility Improvement Account (CMIA) were made, but not recommended for funding: San Juan Rd interchange in Monterey County ($50,800K requested).
In September 2010, the CTC approved for future consideration of funding a project in Monterey and San
Benito Counties that will construct an interchange on Route 101 and modify
existing local roads near the Monterey/San Benito County line. The project
is programmed in the Trade Corridors Improvement Fund and the 2010 State
Transportation Improvement Program and includes local funds. Construction
is estimated to begin in Fiscal Year 2012-13. Total estimated project cost
is $90,600,000 for capital and support. The scope as described for the
preferred alternative is consistent with the project scope set forth in
the proposed project baseline agreement. The project will mitigate
potential impacts to water quality, aesthetics, and riparian habitat. The
project will also require construction activities in the habitat of the
California tiger salamander, the Southwestern pond turtle, and the
California red-legged frog, all of which are federally listed threatened
and endangered species. The project contains mitigation measures to reduce
impacts to these species to a less than significant level.
In May 2011, the CTC approved a new public road connection at San Juan Road to US 101, near the Monterey/San Benito
county line, in the county of San Benito. San Juan Road, Cole Road and
Dunbarton Road are the primary local roads to be modified by this project.
San Juan Road is a two-lane undivided county road that connects to US 101
from the west to form a T-intersection. Acceleration lanes to both
directions of US 101 are provided off of San Juan Road. Cole Road is a
two-lane undivided county road that connects to southbound US 101 from the
west to form a skewed-intersection. To access northbound US 101, Cole Road
extends through a median crossing. Dunbarton Road intersects US 101 on the
southern end of the project limits and serves as the primary southbound
connection in that vicinity. An analysis, conducted on existing traffic
volumes in June of 2008, found that during peak traffic periods the US 101
intersections of San Juan Road, Dunbarton Road, and Cole Road each
operates at a Level of Service “F”. Traffic volume increases
have led to fewer gaps in traffic for the motorist to merge onto the
highway. Currently, vehicles from both directions of travel on US 101 can
directly access Dunbarton Road, and Cole Road west of US 101. San Juan
Road can be accessed directly only from southbound US 101. To get onto San
Juan Road from northbound US 101, a motorist has to either turn onto
Dunbarton Road (North) or make a U-turn at Cole Road. With two lanes of
highway traffic in each direction, access to these roads is especially
difficult. During a three-year study period between September 1, 2004 and
August 31, 2007, it was found that most highway segments and intersections
within the proposed project limits had collision rates higher than the
statewide average for similar facilities. In particular, these studies
show, the San Juan Road intersection has a collision rate 300 percent
higher than the statewide average. The southbound US 101 traffic
approaching Cole Road and San Juan Road are on a 6 percent grade which
tends to increase stopping sight distances. The proposed project would
construct a combination compact half diamond/one-quadrant cloverleaf
interchange. San Juan Road, on the west side of US 101, would be realigned
and extended to the north where it then turns and crosses US 101 as an
overcrossing. Cole Road would be extended southerly until it connects to
San Juan Road at a T-intersection. On the east side of US 101, a new
frontage road would be constructed off of San Juan Road towards the south.
This new frontage road would be constructed parallel to US 101 and end
with a cul-de-sac at Marilyn Lane. Marilyn Lane and Ballantree Lane are
private roads to be connected to this frontage road. Access to Dunbarton
Road (North) from US 101 would be removed. Dunbarton Road (North) would
become a frontage road ending with a cul-de-sac. The north end of
Dunbarton Road (South) would only allow right in and right out traffic
movement. The existing median crossover at Cole Road would be removed. The
gaps in the median barrier on US 101, within the project limits, would be
closed with a concrete barrier. After the completion of the project, it is
proposed that the local roads constructed as part of the project be
relinquished to Monterey County and San Benito County within their
respective areas. The current capital cost estimate for the project is
$46.2 million. This project will be funded using a combination of the
Statewide Transportation Improvement Program which includes the Regional
Improvement Program and the Interregional Improvement Program, local
matching funds from TMAC, American Reinvestment and Recovery Act of 2009
Funds (Federal Stimulus) and Trade Corridor Improvement Funds in the
2012-2013 fiscal years.
In August 2017, the CTC authorized relinquishment of 05-Mon-101-PM-100.3/101.3 Right of way along Route 101 from Dunbarton Road to the San Benito County line, in the county of Monterey, consisting of superseded highway and collateral facilities. The County, by freeway agreement dated April 12, 2011, agreed to accept title upon relinquishment by the State. The 90-day notice period expired July 19, 2017. This evidently was the original routing bypassed by the above project.
In January 2020, the CTC authorized relinquishment of right of way in the
county of San Benito (County) along Route 101 (05-SBt-101-PM 0.00/0.62)
from the Monterey County line to Cole Road, consisting of collateral
facilities. The County by freeway agreement dated April 12, 2011, agreed
to accept the relinquishment and by letter signed August 5, 2019, agreed
to waive the 90-day notice requirement and accept title upon
relinquishment by the State. The 90-day notice period expired November 27,
2019.

San Benito Wildlife Crossing (~ SBT 1.477)
In February 2020, it was reported that the Land Trust
of Santa Cruz County announced it would acquire 2,600 acres of Rocks
Ranch. The trust’s Executive Director Stephen Slade said that Rocks
Ranch is a “must protect” project because it would enable
wildlife to safely cross US 101 and connect the Santa Cruz Mountains with
the Gabilan Range. Wildlife found at Rocks Ranch include bobcats, golden
eagles, and California red-legged frogs. There are also signs of Native
American cultural artifacts, such as bedrock mortars. There is no cost
estimate for the San Benito wildlife crossing. The Rocks Ranch land
connects with US 101 on its northern end, approximately SBT 0.269 to SBT
1.951, based on the map on the Land Trust Assessment Page. Rocks Ranch owner Ben Bingaman, who will keep 60 acres near US 101 that are part of the four nodes under zoning dispute
related to Measure K, said he had been in discussion with the land trust
for about two years. The property is currently used for cattle grazing. He
said he will continue to run cattle on the property for 10 years, which
will be reevaluated at that time.
(Source: BenitoLink, 2/21/2020)
In December 2022, the nonprofit Land Trust of Santa
Cruz County spent $17 million to buy Rocks Ranch, a 2,600-acre property
near San Juan Bautista that developers have eyed in recent years for
subdivisions, hotels and other projects. Instead, the group is working on
a plan with Caltrans to build a wildlife crossing so that mountain lions,
deer, bobcats, badgers, foxes and other animals can traverse four lanes of
speeding traffic on US 101 without being hit by cars. That area is a
hotspot for wildlife-vehicle collisions that not only rack up roadkill but
can injure or kill motorists. The freeway also can block animals from
roaming to breed, find food and settle into new habitat areas. Planning is
still in the early stages for the crossing, which would be the first such
natural bridge built over any freeway in Northern California. The idea is
to connect two places that are still relatively wild: the Gabilan Range
— which runs roughly from Pinnacles National Park to Fremont Peak
near Hollister — and the Santa Cruz Mountains. At the head of the
plan is Rocks Ranch, which has 2.5 miles of frontage on US 101, just south
of Route 156. Caltrans planners are studying several spots along the
property where under crossings could be built below the freeway. But an
overpass would also work ell in several of them. Caltrans should be
finished with a feasibility study by the end of this year, she said. The
agency is applying for several grants to fund engineering and
environmental studies over the next three years, with construction planned
for 2028 if funding can be secured. An overcrossing would probably be 120
to 160 feet wide. It would be constructed of concrete and covered with
grass, brush, rocks, logs and possibly even trees. Fencing would be built
along parts of the freeway to help keep animals off the road and direct
them to the overpass. Planners are also studying a proposal to build a
similar wildlife overpass at Route 152 east of Gilroy, near Pacheco Pass.

US 101 Improvements Project: Monterey Road to Route 129 (SCR 4.9/SCL 5.0)
In August 2018, the CTC accepted the Final Environmental Impact Report and Statement of
Overriding Considerations for the US 101 Improvements Project (Project) in
Santa Clara County and approved the Project for future consideration of
funding. The Project will reconstruct the existing US 101/Route 25
interchange; widen US 101 to a 6-lane freeway between Monterey Street and
Route 129; add auxiliary lanes in each direction on US 101 between
Monterey Street and Route 25; extend Santa Teresa Boulevard from Castro
Valley Road to the US 101/Route 25 interchange; improve the southbound US 101 off-ramp at Route 129; construct frontage roads; grade-separate the
Union Pacific Railroad crossing on Route 25 just west of Bloomfield
Avenue; and will construct bicycle facilities. On June 6, 2013 the Santa
Clara Valley Transportation Authority Congestion Management and Planning
Committee adopted the Final Environmental Impact Report, including the
Statement of Overriding Considerations. The Final Environmental Impact
Report determined that impacts related to growth, farmland, and
visual/aesthetics would be significant and unavoidable. These imacts were:
The Santa Clara Valley Transportation Authority Congestion Management and Planning Committee found that there were several benefits that outweigh the unavoidable adverse impacts of the project. These overriding benefits include economic, legal, social, and technological considerations that outweigh the identified significant effects on the environment. The Santa Clara Valley Transportation Authority Congestion Management and Planning Committee cited the following substantial public benefits:
On July 17, 2018, the Santa Clara Valley Transportation Authority confirmed that the Final Environmental Impact Report remains valid and that there are no new identified impacts requiring mitigation. The Santa Clara Valley Transportation Authority also confirmed that the preferred alternative set forth in the final environmental document is consistent with the Project scope of work programmed by the Commission.
The Project will be constructed in phases, with the
first phase encompassing the reconstruction of US 101/Route 25
Interchange, which is estimated to cost $65,000,000, and will be funded
with with Trade Corridor Enhancement Funds ($4,200,000) and Local Funds
($60,800,000). Construction is estimated to begin in Fiscal Year 2020-21.
Additionally, in August 2018, the CTC approved an allocation of $4,200,000
for the locally-administered Senate Bill 1 (SB 1) Trade Corridor
Enhancement Program (TCEP) US 101/Route 25 Interchange – Phase 1
project (PPNO 0462G), in Santa Clara County
(August 2018 CTC Agenda Item 2.2c.(12), Agenda Item
2.5s(4))
In June 2021, it was reported that the updated US 101/Route 25 interchange is still being designed. The goal of the project
is to increase the length of the southbound US 101 offramp by more than
1,000 feet, in order to prevent vehicles from stacking on US 101 during
peak commute hours. Traffic signals would be installed where the offramp
meets Route 25, and traffic would turn east over a newly constructed
four-lane overpass that spans US 101. Once crossing the overpass, which
would be located slightly north of the current overcrossing, another
signalized intersection will be constructed where the northbound off-ramp
meets Route 25. The overall project, which also includes widening US 101
from Monterey Road to Route 129 as well as extending Santa Teresa
Boulevard to Route 25, will be built in phases due to limited funding. The
first phase, which includes the new overpass, is expected to cost
$100 million, to Adam, funded by Senate Bill 1 and the 2016 voter-approved
Measure B. The project is currently in the design phase, and an addendum
is being drafted for the 2013 VTA Board-approved Environmental Impact
Report for the overall US 101 widening project. Construction on the
overpass could begin in summer 2023 and wrap up in early 2026. The
existing interchange was constructed in 1988 as a temporary way to prevent
drivers from turning left on US 101 to Route 25. Since then, traffic has
increased heavily, with vehicles looking to turn onto Route 25 spilling
onto the US 101 shoulder and backing up to the Monterey Road onramp. In
addition, the current configuration of the interchange has seen
“higher than average accident rates” compared to statewide
collision rates. The project would eliminate US 101 access from Castro
Valley and Mesa roads, which are popular spots for commuters looking to
avoid the bottleneck that occurs when the highway goes down from three
lanes to two at Monterey Road.

In June 2022, it was reported that
the Santa Clara Valley Transportation Authority Board of Directors
approved a document that completes another step in the years-long process
to construct a new overcrossing at the US 101/Route 25 interchange. The
board unanimously approved the addendum to an environmental report for a
US 101 widening project that was previously approved in 2013. The addendum
focuses on the first phase of the US 101/Route 25 interchange, and
determined that mitigation measures in place for the project would not add
any new or significant environmental effects. Located just south of Gilroy
city limits, the current interchange, built in 1988, was originally meant
to be a temporary way to prevent drivers from turning left on US 101 to
Route 25. However, the interchange has proven inadequate as the population
has grown over the decades, and traffic on southbound US 101 backs up past
Monterey Street during daily commute hours, as drivers attempting to
navigate onto Route 25 into San Benito County line up on the
freeway’s shoulder. While still being designed, the project would
increase the length of the southbound US 101 offramp by more than 1,000
feet, with the goal of preventing vehicles from stacking on US 101 during
peak commute hours. Traffic signals would be installed where the offramp
meets Route 25, and traffic would turn east over a newly constructed
four-lane overpass that spans US 101. Once crossing the overpass, which
would be located slightly north of the current overcrossing, another
signalized intersection will be constructed where the northbound off-ramp
meets Route 25. The overall project, which also includes widening US 101
from Monterey Street in Gilroy to Route 129 in San Benito County as well
as extending Santa Teresa Boulevard to ROute 25, will be built in phases
due to limited funding. The project is expected to cost at least $500
million in today’s dollars. The first phase, which includes
the new overpass, is expected to cost $100 million. Construction is
tentatively planned to begin in mid-2024 and take three years to complete.
With the June 2 approval, the VTA will continue seeking right-of-way
approvals on properties surrounding the project. That includes acquiring
and demolishing the Garlic Shoppe and Rapazzini Winery, which are in the
path of the proposed northbound US 101 off- and on-ramps, according to the
VTA’s addendum. The first phase of construction would also block off
highway access on Castro Valley and Mesa roads, two popular merging points
for commuters looking to bypass the congested Monterey Street onramp.
Traffic would detour through Gilroy to the Monterey Street onramp until
the Santa Teresa Boulevard extension to the new interchange is completed,
which currently has no timeline.

In Spring 2003, widening was completed on a four-lane section of US 101 between Cochran Road in Morgan Hill (~ SCL R17.819) and Bernal Road in San Jose (~ SCL R27.03), bringing it to four lanes in each direction including one HOV lane. This added 7.5 miles more of commute lane operating the usual 5-9 and 3-7 period from Morgan Hill all the way to Redwood City.
Morgan Hill to Palo Alto Express Lanes (04-SCl-101, PM 16.00/52.55)
In July 2011, legislation was approved to permit the VTA to construct express lanes in locations outside its authority. As background: In 2004, a bill was approved to create express lanes on US 101 in San Mateo and Santa Clara counties. Starting in 2015, motorists would be able to opt to pay to travel in the lanes, a tool to ease congestion that is currently used in other parts of California. However, under this law, the express lanes were to be monitored by the Santa Clara Valley Transportation Authority, whose jurisdiction ends at the San Mateo County border. The VTA would have been unable to construct and maintain the express lane along the 6-mile stretch of US 101 between Redwood City and the county border. The new legislation permits VTA to construct and maintain that 6-mile stretch.
In October 2015, the CTC approved for future consideration of funding the US 101 Express Lanes
Project. This project in Santa Clara County will construct express lanes
on US 101 in both directions from East Dunne Avenue in Morgan Hill to the
Santa Clara/San Mateo County Line in Palo Alto (04-SCl-101, PM
16.00/52.55) and restripe a portion of Route 85 in Mountain View
(04-SCl-85, PM 23.0/R24.1). The project is not fully funded. The project
is programmed in the Santa Clara Valley Transportation Authority’s
Federal Transportation Improvement Program with local funds. The total
estimated cost is $431,000,000 for capital and support. Depending on the
availability of funds, construction is estimated to begin in Fiscal Year
2017/18.
In October 2016, it was reported that Caltrans is
beginning to study a plan Thursday to link "managed lanes" on US 101 in
Santa Clara County to new ones in San Mateo County. Possibilities includes
converting existing carpool (HOV) lanes to express lanes and adding new
express lanes on US 101 between Whipple Road and the I-380 interchange in
San Mateo County. It could also include reconstructing ramp connections to
US 101 and installing electronic toll collection.

The 2018 STIP, approved at the CTC March 2018 meeting, also appears to create a number of PPNOs for this project. On US 101, there is PPNO 2015E US 101/Route 85 Silicon Valley Express Lns Program-Ph3; PPNO 2015J US 101
Silicon Valley Express Lns Program-Ph5-ETS; and PPNO 2015H US 101 Silicon
Valley Express Lns Program-Ph5-Civil. According to the VTA page on the program, the US 101 portion will convert 36 miles on US
101 to express lanes and add a second express lane for the majority of the
corridor from Dunne Avenue in Morgan Hill to the San Mateo County line.
The second express lane will provide a two-lane facility within urbanized
segments. The US 101 express lanes will connect with the Route 85 express
lanes in San Jose and convert US 101/Route 85 HOV direct connectors in
Mountain View to express lane connectors. Based on the map from VTA (see
above), Phase 3 runs from ~ SCL 43.909 (Lawrence Expwy) to the San Mateo
County Line. Phase 5 runs from I-880 to Lawrence Expwy (~ SCL 38.352 to
SCL 43.909). On Route 85, there is PPNO 2015F Route 85 Silicon Valley
Express Lns Program-Ph4-Civil; and 2015G Route 85 Silicon Valley Express
Lns Program-Ph4-ETS. According to the VTA page on the program, the Route 85 portion will convert approximately
24 miles of existing High Occupancy Vehicle (HOV or carpool) lanes to
express lanes and will add a second express lane between Route 87 and
I-280 in the median. The project will also convert the existing HOV direct
connector in south San Jose from US 101 to Route 85 to an express lane
connector. Based on the map from VTA (see above), Phase 4 includes the
portion on US 101 from 101 SCL R25.292 to SCL R26.873.

In May 2021, the CTC received notice that VTA proposes
to delete STIP construction (CON) funds from the Silicon Valley Express
Lanes Program – Phase 5 Civil project (PPNO 2015H) and reprogram
those funds to cover the Right of Way (RW) and construction funding
shortfall for the I-280 Soundwalls – Route 87 to the Los Gatos Creek
project (PPNO 0503J) in Santa Clara County. Currently $3,207,000 in
Regional Improvement Program (RIP) STIP funds are programmed in Fiscal
Year 2022-23 to the CON phase for the Silicon Valley Express Lanes Program
- Phase 5 Civil project. Based upon the latest design, the
construction cost for this project is estimated to be approximately $100
million. Last year, VTA applied for funding from the SB-1 Cycle 2
Programming for the Silicon Valley Express Lanes Program – Phase 5
Civil project, however, the project did not receive SB-1 funds. Due
to the unavailability of alternate funding, the CON phase remains
partially-funded, and STIP guidelines do not allow partially-funded
components. Therefore, VTA is requesting to delete CON funds and reprogram
those funds to cover the cost increase for the I-280 Soundwalls
project. Separately, the project is requesting a time extension for
allocation of already programmed RW funds for the Silicon Valley Express
Lanes Program – Phase 5 Civil project. The I-280 Soundwalls –
Route 87 to Los Gatos Creek project (PPNO 0503J) is currently programmed
in STIP for Environmental, Design, RW and CON phases. Due to the
COVID-19 impacts, both the RW and CON schedules have been delayed.
As a result of these delays and the escalation in costs based upon the
updated design information have resulted in cost increases for both RW and
CON. Therefore, VTA is requesting to re-program $3,207,000 RIP STIP
funds from the Silicon Valley Express Lanes Program – Phase 5 Civil
project to cover cost increases for the I-280 Soundwalls project as
follows: $644,000 for RW and $2,563,000 for CON.

In May 2010, Caltrans began a $24 million repaving of the 15-mile stretch
of US 101 from Route 85 in South San Jose (~ SCL R26.893) to the San Jose
airport (~ SCL 39.977). Crews will remove the top three inches of highway,
installing rubberized asphalt that will allow water to seep through the
pavement and drain off to the side of the road. It's a type of pavement
that greatly reduces visibility problems in the rain when water sprays off
tires. Caltrans hopes to repave nearly all eight lanes and 67 ramps by
Labor Day 2010. That will be the first of $300 million worth of upgrades
planned for US 101 through 2012. About $120 million is coming from state
bonds approved by voters in 2006, and gas taxes, local sales taxes and
stimulus funds will cover the rest. In Fall 2010, workers will begin
rebuilding the Tully Road interchange and adding an extra southbound lane
from Story Road to Capitol Expressway — a $60 million project
expected to take two years. In 2011, a third project will lengthen carpool
lanes and add merging lanes from the Route 85/US 101 interchange in
Mountain View to Palo Alto, a $103 million effort. Lastly, merging lanes
and updated metering equipment will be added from Palo Alto to Menlo Park
for an additional $113 million.

Yerba Buena Road (~ SCL 30.998) to I-280 (~ SCL 34.805) Widening
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $4,000,000 for High Priority Project #2245: US 101 Corridor Improvements – I-280 to the Capitol-Yerba Buena Interchange.
In 2007, the CTC considered a number of requests for funding from the Corridor Mobility Improvement Account (CMIA). one request was funded: construction of auxiliary lanes from Route 85 to Embarcadero in Santa Clara County ($84.93M). Requests to widen the route from Yerba Buena to I-280/I-680 in Santa Clara County, and to widen the route from Route 25 to Monterey Rd in Santa Clara County were not recommended for funding. In August 2010, the CTC amended the CMIA baseline agreement for the US 101 Improvements (I-280 to Yerba Buena Road) project (PPNO 0460C) to update the project delivery schedule. Construction will now begin in September 2010 and complete in June 2013, with project close-out completing in June 2014.
In June 2011, it was reported that the California Transportation Commission has recommended allocating $24 million in state bonds for a $31.1 million project to realign the ramps and ease the merging issues that occur at the Capitol Expressway. Among the likely improvements: The ramp to north US 101 from Yerba Buena Road will be widened to two lanes with a metering light installed; a new ramp to north US 101 from the road between Yerba Buena and the expressway will be added, allowing traffic from Yerba Buena to enter the freeway before Capitol rather than merging with expressway ramp traffic; and the southbound US 101 off-ramp to Yerba Buena will be widened to two lanes and realigned to exit directly from US 101.
Tully Road Interchange Improvements (~ SCL 32.947)
In October 2009, the CTC approved for future consideration of fuinding a project in Santa Clara
County that will construct one additional lane in the southbound direction
from south of the Story Road Interchange to south of the Capitol
Expressway Interchange, modify the Route 101/Tully Road Interchange to a
partial cloverleaf interchange, and rebuild the existing Tully Road
Overcrossing. The project is programmed in the Corridor Mobility
Improvement Account and the 2008 State Highway Operation and Protection
Program, and includes Federal Demonstration funds and local funds. Total
estimated project cost is $62,975,000, capital and support. Construction
is estimated to begin in Fiscal Year 2009-10. The scope as described for
the preferred alternative is consistent with the project scope set forth
in the approved project baseline agreement.
In January 2011, it was reported that work was beginning on the Tully Road interchange reconstruction. The first step was demolishing sections of the overpass that opened in the 1950s. The project is expected to cost $45 million and take 16 months. The project will include replacing some of the cloverleaf ramps with diagonal exits similar to those at Lawrence Expressway and US 101; addition of a merging lane on southbound US 101 between Tully and Capitol; addition of an additional lane southbound between Story Road and the expressway; and replacing and widening the Tully Road bridge with an additional lane in each direction, widening the shoulders to eight feet and raising the bridge to allow trucks to more easily pass underneath. Construction was to have begun in late 2011, but the state's budget delays pushed back the start until 2011. However, the delay and the recession resulted in a bid $10 million under the projected cost.
In June 2012, it was reported that Caltrans announced the completion of a $45 million project to relieve traffic congestion at Tully Road and US 101 in San Jose. The project constructed an additional lane on southbound US 101 from south of Story Road to north of the Capitol Expressway, and added a southbound merging lane from Tully Road to Capitol Expressway. In addition to the added lanes, the entire highway interchange at Tully Road was replaced and enhanced with traffic signals and wider off-ramps.
In June 2009, the CTC approved relinquishment of right of way in the city of San Jose along Route 101 near Alum Rock Avenue on N 31st Street (4-SCl-101-PM R35.8), consisting of a relocated or reconstructed city street and an adjoining nonmotorized transportation facility, namely a pedestrian walkway.
In September 2015, Mr. Roadshow was asked about the possiblity of
upgrading the I-880/US 101 interchange (~SCL 38.268) in San Jose; in
particular, this would involve creating flyovers in all directions
(including SB I-880 to NB US 101). Roadshow reported that the Valley
Transportation Authority estimates it would cost $1 billion to upgrade
this interchange. This is the most expensive highway project on the list
of 84 potential improvements in Santa Clara County by 2040.

Highway Widening: Route 87 (~SCL 39.876) to Trimble Road (~ SCL 40.689)
In June 2001, the CTC had on its agenda addition of a northbound lane through San Jose, Route 87 (~SCL 39.876) to Trimble Road (~ SCL 40.689) in Santa Clara county. There are also plans to widen the route to 3-lanes + HOV each direction from Burnett Road to Route 85. In June 2002, plans were unveiled to widen the route from Marsh Road to Ralston Avenue in Belmont. The widening between Bernel Road to Burnett Road (four to eight lanes) is TCRP Project #3, requested by the Santa Clara Valley Transportation Authority. Per SB 1318, 9/28/10, this project was authorized for $25,000,000.
The addition of the northbound lane from Route 87 to Trimble Road is TCRP Project #5, again requested by the Santa Clara Valley Transportation Authority. According to a poster on m.t.r, in May 2003 new southbound lanes between Route 85 and Cochrane Road were completed making US 101 8 lanes (with variations of 10 lanes in certain spots) between San Francisco, all the way down to Morgan Hill for nearly 70 consecutive miles.

Trimble Road / De La Cruz Road Interchange (~ SCL 40.714)
In November 2018, it was reported that there are plans to redesign the
Trimble Road / De La Cruz Road Interchange (~ SCL 40.714) now that the
lawsuit over the Measure B transportation tax has been thrown out. The
project is in the design phase and VTA anticipates that it will be fully

In February 2021, it was reported that construction
would begin in Summer 2021 on the US 101/De La Cruz Interchange project.
This is a 2016 Measure B-funded project being done by VTA and the City of
San Jose, in cooperation with the California Department of Transportation
(Caltrans). The purpose of this project is to improve traffic flow and
enhance safety for vehicles merging onto southbound US 101 from the De La
Cruz Boulevard/Trimble Road interchange, and to upgrade mobility and
safety for bicyclists and pedestrians traveling over the highway and by
the interchange ramps adjacent to the San Jose International Airport. The
problem is that the 60-year-old interchange does not meet current design
standards in an area that continues to experience increased
growth-producing higher traffic volumes during normal conditions.
Increased congestion along the Trimble Road/De La Cruz Boulevard
overcrossing is due to the lane reductions from six-lanes to four-lanes on
the north and south sides of the overcrossing. Safety is also a main
concern for bicyclists that must merge and share lanes with vehicles
across the bridge structure with a minimal buffer between the walkway and
the roadway. The proposed improvements will include, but are not limited
to the following:

In August 2018, it was reported that the VTA will approve the final pieces of a funding package
in September 2018 to begin construction of a new $48 million interchange
for the Mathilda Monster at US 101 and Route 237. Work could begin by late
December 2018, and, if all goes well, be done by the end of 2019. This
includes widening Mathilda to three lanes, new stop lights and better

HOT/Carpool Lanes - Route 237 (~ SCL 46.21) or Redwood City (~ SM 6.619) to I-380 (~ SM R20.695) and South San Francisco (~ SM 22.711) to San Francisco (~ SM 26.107/SF 0.0)
In June 2015, it was reported that the City/County Association of Governments
(C/CAG) has decided to move forward with securing $16.5 million in grants
to study the feasibility of adding auxiliary, carpool and toll lanes to
ease traffic on US 101. The C/CAG board approved two resolutions Thursday,
June 11, 2015 to apply for Measure A highway funds to study adding
auxiliary lanes from Oyster Point in South San Francisco north to San
Francisco and carpool/toll lanes from Whipple Avenue in Redwood City to
the I-380 interchange. Traffic is so bad on US 101, that Assemblyman Kevin
Mullin, D-South San Francisco, introduced legislation in February 2015 to
develop a strategy to tame traffic as the rebounding economy has led to
slower commutes. Mullin’s AB378 makes congestion relief on the
48-mile stretch of highway between San Francisco and San Jose a priority.
The bill declares that the corridor is the most economically productive
and important stretch of highway in the state and that its transportation
capacity is “grossly insufficient” to serve the “growing
number of commuters.”

In October 2015, it was reported that the San Mateo
County Transportation Authority allocated $22 million to help fund the
environmental review phase of four other projects along the San

commuter lane from Whipple Avenue to the San Mateo County and San
Francisco border, as well as consideration of an auxiliary lane dedicated
to those exiting US 101 somewhere between I-380 and the northern border of
the county.

potential construction can actually take place on the corridor. C/CAG has
also requested another $8.5 million from the San Mateo County

plan now is to bring the lanes south from the Santa Clara County border
north to I-380 in San Bruno.

In July 2016, it was reported that a shuffling of
federal funds, once committed to a series of projects that are
languishing, are being redirected to the express lane effort through San
Mateo County to the San Francisco city line. Caltrans still needs to
approve the idea, however regional transportation officials endorsed the
$8.9 million funding shift. That won’t be nearly enough to build the
lanes, but it will get the project started by paying for the planning,
engineering and required environmental studies. It replaces about $9.6
million that was set aside for the study back in May by the CTC, but
subsequently pulled due to a drop in state gas tax revenue. Additionally,
in August 2016, an additional $3 million in private funds was received
from the San Mateo County Economic Development Association, or SAMCEDA.
The Bay Area Council has been working with transportation leaders to push
for carpool or express lanes on US 101 into San Francisco. Caltrans has
agreed, he said, to begin engineering and design work for the US 101 lanes
as environmental studies are being done. That should cut the time to
complete the work from as much as 10 years to as little as five. The big
challenge is finding the money to build the lanes. State and federal funds
for transportation projects are declining, which puts more pressure on Bay
Area counties and the region to pay for its own improvements while hoping
the state comes up with a transportation funding plan. Engineers will
consider a variety of options, including converting an unrestricted lane
into a carpool lane, a move that would be unpopular with single-occupant
drivers. Or they might combine and connect a series of short lanes between
on- and off-ramps and by building on shoulders.

In June 2017, an update was provided on the
environmental review related to the widening of US 101 in San Mateo
County. Widening the freeway by adding express lines incentivizes the
movement from single occupancy cars to higher occupancy vehicles, but also
does exactly the opposite, creating more space for more single occupancy
vehicles – Caltrans is expecting the number of vehicles on US 101 to
jump from between 4 and 7 percent in just the next three years. Most of
the update addressed how ten through lanes can be squeezed into the
limited space available, a strong hint that county and state officials
favor widening the highway rather than addressing congestion by providing
better bus and carpool services. “An auxiliary lane begins and ends
at on and off ramps, it doesn’t go through… we actually will
literally pave through the interchange and connect the auxiliary lanes to
create a through lane,” explained the presenter. “We are
actually looking at re-aligning the freeway, taking the center line and
moving it, typically to the west, and what that allows us to do is create
more width.” Caltrans officials are at least allowing an option that
would avoid widening the highway but still provide increased capacity by
converting an existing lane in each direction to an express lane to be
studied the project’s environmental impact report, although the
focus of the planning work so far indicates they aren’t serious
about that option. Converting existing lanes to express lanes rather than
widening US 101 would save about $200 million, money that could be spent
on boosting SamTrans’s bus service, further Caltrain upgrades beyond
electrification, and other transportation demand management programs in
San Mateo County. But officials were silent at the meeting on the details
of how transit could help alleviate traffic congestion, or how to pay for
better transit, only stating that a separate study of highway bus service
had just begun. The current $11.5 million environmental impact report for
express lanes on US 101 in San Mateo County is expected to be finished in
January 2018.

The 2018 STIP, approved at the CTC March 2018 meeting, appears to allocate $33.5M for PPNO 0658D, Managed Lanes, 22 mi (Matadero Creek-Rt 380) (SCL 051.37 to ~ SM R20.695). R/W was programmed prior to FY18-19 for $16M; construction support for $17.5M appears to be in FY20-21.
In April 2018, it was reported the that effort to bring
express lanes to the stretch of US 101 that runs through San Mateo County
has taken a step toward the design phase despite persisting concern about
charging tolls to drive on those lanes. C/CAG voted 10-6 on April 12, 2018
to approve a memorandum of understanding and cooperative agreements for
the managed lanes project, which is currently in the final stages of the
environmental review process. The $514 million proposal, which has been in
the works for years, would create a new express lane in each direction on
US 101 from Whipple Avenue in Redwood City to I-380 in San Bruno for
carpoolers and those willing to pay. The 14-mile stretch of highway could
include up to seven zones with fluctuating tolls based on demand, though
rates have yet to be determined. Solo drivers would pay full price,
two-person carpools and clean energy vehicles may see a discount and
carpools of three or more along with buses and motorcycles would ride
free. The plan includes connecting existing auxiliary lanes to create a
new lane while squeezing every possible inch of available space. The far
left lane in each direction would then be converted into a managed lane
with commensurate signs and real-time surveillance equipment installed.

It will also convert the existing HOV lanes on HOV lane direct connector ramps. $233,200,000.
In July 2018, it was reported that, in parallel with
the final stages of the environmental review phase, San Mateo officials
were determining the agency or combination of agencies that will own and
operate it the express lanes, as well as the potential toll rates for the
proposed express lanes and the revenue they could generate. Several board
members, for example, were surprised and less than thrilled to learn that
they will only be choosing between no project or express lanes moving
forward. Past alternatives, such as carpool lanes, are now off the table.
While toll policies haven’t been decided and prices would fluctuate,
Leo Scott, a consultant with Gray-Bowen-Scott, said estimates suggest
tolls would average nearly $1 per mile on the stretch of US 101 in San
Mateo County, which is on the cheaper end compared to express lanes
elsewhere in the nation. The immediate decision facing the board is what
agency will own and operate San Mateo County’s express lanes if
they’re installed. Scott said the decision is needed now because the
owner determines the operator and the operator’s input is needed
during the design phase, which is “progressing rapidly.” The
owner would own the tolling equipment and related highway infrastructure,
set policy and rates and pay for the operation and maintenance of the
facility, among other duties. They’re also responsible for
liabilities. The operator, on the other hand, would manage day-to-day
operations and maintenance. The board can create its own agency to own and
operate the facility or it could outsource the operator role to the Santa
Clara Valley Transportation Authority. Another option is to hand the reins
over to the Metropolitan Transportation Commission, in which case it would
both own and operate the express lanes, per MTC’s policy. The
environmental review for Managed Lanes is expected to wrap up in October
and the design phase in the summer of 2019, while the entire project is
scheduled to be complete by 2021.

In August 2018, it was reported that there was some
opposition to the lanes. Santa Clara County Board of Supervisors President
Joe Simitian said the proposal to add toll lanes to major freeways emerged
when he sat on a transportation committee as a state senator. He had a bad
feeling about the lingering financial effects the fees would have on
residents who already had a hard time balancing the expenses of living in
Silicon Valley. “I was concerned that folks who were beginning to
look at freeways as revenue sources may squeeze out those who could not
afford additional fees,” Simitian said. “There was a potential
to create two Californias – one for folks who are prosperous and one
for folks of modest means. Those who couldn’t afford the fees would
be stuck with a second-tier infrastructure.” The financial model
behind the toll lanes adds up in Simitian’s mind, but that
doesn’t mean he supports it.

In August 2018, it was also reported that Foster City
Council has come out against the idea of putting toll lanes on US 101
— and Mountain View Mayor Lenny Siegel and San Mateo County
Supervisor David Canepa share that view. In a letter sent Wednesday (Aug.
15) to Caltrans, the San Mateo County Board of Supervisors and the San
Mateo County City/County Association of Governments, Mayor Sam Hindi wrote
that council doesn’t want to see the agency allow single-occupancy
vehicles to pay to use express lanes. Hindi also said charging to drive in
fast lanes would further burden poor residents whose housing costs have
continued to rise. Hindi suggested that Caltrans accommodate more
high-capacity vehicles in additional carpool lanes instead. Siegel, the
Mountain View mayor, sent a letter to Caltrans about the toll lanes,
saying the project would slam Mountain View with traffic from all of the
solo drivers. He’s concerned the toll lanes may entice tech workers
to pay to drive in express lanes rather than take the bus.

between local and regional control. The two remaining options on the table
are to have San Mateo County own the express lanes and have the Santa
Clara Valley Transportation Authority operate them, or to hand over
ownership and operation duties to the Bay Area Infrastructure Financing
Authority, a joint powers authority between the Metropolitan
Transportation Commission and the Bay Area Toll Authority. BAIFA manages
other express lanes, including I-680 in Contra Costa County. The owner and
operator decision is up to both the San Mateo County Transportation
Authority, which oversees the county’s sales tax revenue earmarked
for transportation, and the City/County Association of Governments. C/CAG
is a joint powers authority comprised of board members representing each
city and the county that works on quality of life issues such as air
quality and transportation, among others.

In December 2018, the CTC approved for future consideration of funding the U.S. Highway 101 Managed Lanes Project,04-SCL-101, PM 50.6/52.6, 04-SM-101, PM 0.0/21.8. This project is located on US 101 within cities of San Carlos, Millbrae, Burlingame, San Mateo, Menlo Park, Palo Alto and Belmont in San Mateo and Santa Clara Counties. The project proposes to provide continuous traffic management in each direction on US 101 in Santa Clara County by providing express lanes and transportation options within the project corridor and region. Transportation options include encouragement of carpooling, public transit and new technology and/or design features to assist traffic management. The funding for the proposed project is anticipated from various resources including Federal Earmark funds, Local Measure funds, Regional Toll revenue, Senate Bill 1 funds, State Transportation Improvement Program funds and private sector funds. The proposed project is estimated to cost approximately $514.3 million, is fully funded and programmed for that amount. Construction is estimated to begin in Fiscal Year 2019-20. A copy of the FEIR has been provided to Commission staff. Resources that may be impacted by the project include visual/aesthetics, cultural, hydrology, water quality, geology/soils, hazardous materials, air quality, noise, and biological resources.
The CTC also received an informational report that
Department, San Mateo County Transportation Authority (SMCTA) and the
City/County Association of Governments (C/CAG) proposed to amend the San
Mateo and Santa Clara US 101 Managed Lanes Project (PPNO 0658D) to
split-out a portion of the scope of work into a new segment for early
delivery. Specifically, they proposed to accelerate the overall delivery
commitment of the US 101 Managed Lanes project by delivering a portion of
the project scope early. Of the 44 lanemiles of managed lanes to be
constructed, 15.6 lane-miles involves mostly reconstruction of the median
and restriping of the existing lanes, along with installing infrastructure
needed for operation of the express lanes; no roadway widening or utility
relocation efforts are needed in this section. Early delivery of this
segment (15.6 lane-miles), combined with the delivery of the adjacent
Silicon Valley Express Lanes project (19.3 lane-miles), will provide much
needed relief to the travelling public by providing a combined total of
34.9 lane-miles of express lanes between these two contracts. They also
proposed splitting the overall US 101 Managed Lanes project into two
segments:

In January 2019, it was reported that new offers,
demands and concerns are continuing to surface as local policymakers work
out the owner/operator arrangement for the express lanes planned for the
San Mateo County section of US 101. The back-and-forth is picking up as a
deadline looms that, if not met, will add time and cost to the $514
million project aiming for completion by the middle of 2022. The owner of
the tolling facility gets to implement an equity program if it wants to
make the express lanes more affordable for low-income drivers, and it also
sets tolling policies. Questions for the future owner include: Should
there be a cap for tolls so that they never exceed a certain dollar
amount? Should carpools of two people ride free or at a discount and
should clean air vehicles such as Teslas also ride free on express lanes?
The TA appears ready to vote on the local ownership approach with BAIFA as
the operator while C/CAG appears somewhat more divided on the matter. Some
members, it seems, are still interested in making BAIFA both the owner and
operator, though most have expressed interest for one of the two local
control options.
(Source: San Mateo Daily Journal, 1/22/2019)
Later in January 2019, it was reported that agreement
on the operation of the managed lanes was finally reached.The preferred
arrangement would ensure local control is retained. Local control in this
context means the City/County Association of Governments and the San Mateo
County Transportation Authority would both own the tolling facility coming
to the stretch of US 101 in San Mateo County and the Bay Area
Infrastructure Financing Authority would operate it. That arrangement was
unanimously selected by an ad-hoc subcommittee comprised of C/CAG and TA
members at a meeting in late January before both boards cast final votes
mid-February. Now that the subcommittee agreed to maintain local control
of the tolling facility, the C/CAG and TA boards have to determine how
they will share ownership. Creating a joint powers authority between both
boards has been suggested numerous times, but that’s just one
potential approach. The subcommittee agreed to hold another meeting at the
beginning of February to discuss potential power-sharing arrangements
before C/CAG and the TA vote on the owner/operator in mid-February.

In January 2019, the CTC approved amending the San
Mateo and Santa Clara US 101 Managed Lanes Project (PPNO 0658D) in San
Mateo/Santa Clara Counties, to split-out a portion of the scope of work
into a new segment for early delivery, as described and noticed above in
December 2018. They also approved an allocation of $2,027,000 for the
State-Administered US 101 Managed Lanes Project – Northern Segment
(04-SCL, SM-101 50.6/52.5, 0.0/21.8) Senate Bill 1 (SB 1) Local

In February 2019, it was reported that the operation
question was finally settled. The owner/operator arrangement for the
Managed Lanes project is now official after unanimous votes by both C/CAG
and the TA. Ownership of the tolled express lane facility coming to US 101
in San Mateo County belongs to both the San Mateo County Transportation
Authority and City/County Association of Governments, and those agencies
will contract with the Bay Area Infrastructure Financing Authority to
operate the facility. C/CAG and the TA also voted to create a joint powers
authority to make policy decisions related to the express lane facility
and that JPA will be comprised of an equal number of members from the TA
and C/CAG. The half-a-billion-dollar Managed Lanes project aimed for
completion by 2022 will construct a new lane in each direction of US 101
in San Mateo County and then the far left lane in each direction will be
converted to a tolled express lane with real-time surveillance equipment.
Such a facility promises speeds of 45 mph at all times on the express
lanes, which will be free for buses and carpools of three people or more,
but other motorists who choose to use those lanes will have to pay a toll.
Tolls will fluctuate based on traffic volumes, but initial projections
suggest prices will average $1 per mile in San Mateo County.

In March 2019, Caltrans was promising traffic
congestion relief in three years (i.e, by 2022), through the $567 million
project that will bring new express lanes to the Bayshore Freeway from
Redwood City south of Whipple Ave. to the I-380/US 101 interchange in the
South San Francisco/San Bruno area, just north of San Francisco
International. Existing HOV lanes from Redwood City south to the Route 237/US 101 interchange in Sunnyvale will be covered to express lanes.
About half of the cost is being covered by Senate Bill 1, which provides
$54 billion for road maintenance and rehabilitation and for congestion
relief. Completion date will be in 2022. An estimated two million vehicles
use this stretch of US 101 on a weekly basis.

In October 2019, AB 919 (Chapter 497, 10/3/2019) amended Section 149.6 of the Streets and Highways Code to read (relevant portions shown, some details on bonds and allocation of funding omitted):
149.6. (a) Notwithstanding Sections 149, 149.7, and 30800, and Section 21655.5 of the Vehicle Code, the Santa Clara Valley Transportation Authority (VTA) created by the Santa Clara Valley Transportation Authority Act (Part 12 (commencing with Section 100000) of Division 10 of the Public Utilities Code) may conduct, administer, and operate a value pricing program on any two of the transportation corridors included in the high-occupancy vehicle lane system in the County of Santa Clara in coordination with the Metropolitan Transportation Commission and consistent with Section 21655.6 of the Vehicle Code.
(b) Notwithstanding Sections 149, 149.7 and 30800, and Section 21655.5 of the Vehicle Code, VTA may conduct, administer, and operate a value pricing program on State Highway Route 101 in San Mateo County in coordination with the City/County Association of Governments of San Mateo County and with the San Mateo County Transportation Authority and consistent with Section 21655.6 of the Vehicle Code.
(c) (1) VTA, under the circumstances described in subdivisions (a) and (b), may direct and authorize the entry and use of those high-occupancy vehicle lanes by single-occupant vehicles for a fee. The fee structure shall be established from time to time by VTA. A high-occupancy vehicle lane may only be operated as a high-occupancy toll (HOT) lane during the hours that the lane is otherwise restricted to use by high-occupancy vehicles.
(2) VTA shall enter into a cooperative agreement with the Bay Area Toll Authority to operate and manage the electronic toll collection system.
(d) With the consent of the department, VTA shall establish appropriate performance measures, such as speed or travel times, for the purpose of ensuring optimal use of the HOT lanes by high-occupancy vehicles without adversely affecting other traffic on the state highway system. Unrestricted access to the lanes by high-occupancy vehicles shall be available at all times, except that those high-occupancy vehicles may be required to have an electronic transponder or other electronic device for enforcement purposes. At least annually, the department shall audit the performance during peak traffic hours and report the results of that audit at meetings of the program management team.
(e) Single-occupant vehicles that are certified or authorized by VTA for entry into, and use of, the high-occupancy vehicle lanes in the County of Santa Clara and San Mateo County are exempt from Section 21655.5 of the Vehicle Code, and the driver shall not be in violation of the Vehicle Code because of that entry and use.
(f) VTA shall carry out a value pricing program established pursuant to this section in cooperation with the department pursuant to an agreement that addresses all matters related to design, construction, maintenance, and operation of state highway system facilities in connection with the value pricing program. An agreement to carry out the program authorized pursuant to subdivision (b) shall be subject to the review and approval by the City/County Association of Governments of San Mateo County and the San Mateo County Transportation Authority.

In December 2019, the CTC had on its agenda a proposal
to document the delivery of the total scope of work for the US 101 Managed
Lanes Project – North Segment (PPNO 0658D) in San Mateo County in
three separate contracts: 1) Construction of express lanes, 2) Tolling
system integration, and 3) Follow-up landscaping work. The project
received a construction allocation at the October 2019 Commission meeting.
The US 101 Managed Lanes project was adopted into the SCCP and LPP at the
May 2018 Commission meeting. The project scope consists of constructing 22
miles of managed lanes in each direction, from south of the Santa Clara
county line to just north of I-380 Since the scope of work for the
southern portion of the overall project consisted mainly of converting the
existing high occupancy vehicle (HOV) lanes into express lanes, the
project delivery team recognized an opportunity to early-deliver this
southern segment. An early delivery of this segment, combined with the
delivery of the adjacent SB 1 funded Silicon Valley Express Lanes project,
will offer much-needed relief to the travelling public earlier than
originally planned. At its December 2018 meeting, the Commission approved
splitting the overall US 101 Managed Lanes project into two segments (as
noted above): (1) US 101 Managed Lanes – North Segment (from Whipple
Avenue to just north of I-380; PPNO 0658D), and (2) US 101 Managed Lanes
– South Segment (from south of the county line to Wipple Avenue
Interchange; PPNO 0658H). The south segment also received an allocation of
construction funds at the December 2018 meeting and is currently under
construction. The US 101 Managed Lanes – North Segment (PPNO 0658D)
received an allocation of construction funds at the October 2019
Commission meeting, and follow-up landscaping project (PPNO 0658J) was
also split-off at the time of this allocation. Along with the construction
of express lanes, the north segment scope of work also includes the
development, installation and testing of the tolling system. That
contract, to be funded solely with local funds, will be administrated as a
separate contract. At its August 2019 meeting, the Commission approved an
application from the San Mateo County Express Lanes Joint Powers Authority
(JPA) to develop and operate a high-occupancy toll facility for this
project. The San Mateo County Transportation Authority (SMCTA) will be the
implementing agency for this tolling system integration contract. This
amendment splits off that tolling system integration, giving:

In February 2020, it was reported that project
construction from Whipple Avenue to I-380 in San Mateo County is underway.
Construction activities on US 101 from Whipple Avenue (in Redwood City) to
I-380 (in South San Francisco) will include removing vegetation,
installing a Smart Traffic System of changeable message signs placed in
the construction zone that shows real-time traffic conditions, installing
environmentally-sensitive area fencing, and temporary freeway striping.
This work will occur on the freeway lanes, shoulders, and ramps. South of
Whipple Avenue, construction activities on US 101 from San Antonio Road
(in Palo Alto) to Whipple Avenue (in Redwood City) will include minor
construction activities to connect to existing electrical connections and
install landscape mulching. This will include work on the freeway
shoulders and ramps. Future construction activities will include
continuing vegetation removal activities, installing erosion control
protection, installing environmentally-sensitive area fencing, installing
concrete barriers next to the travel lanes, temporary freeway striping,
setting up a Smart Traffic System, installing construction/detour signs
north of Whipple Avenue, and installing temporary loop detectors. In
addition, permanent striping, and erosion control will be finishing south
of Whipple Ave.

In December 2020, it was reported that the San Mateo
County US 101 Express Lanes Project is on schedule to be completed and
open in late 2022, but drivers will still see overnight lanes closures in
2021. Beginning in early 2021, Caltrans construction crews will begin more
work on the center median of US 101, as well as some sound wall removals
and reconstruction. Some Caltrans work would require overnight lane
closures and off-ramp closures, but transportation authorities are working
on plans to minimize the impact on residents and drivers. No date for
specific lane closures or off-ramp closures has been set. Caltrans
construction crews are meeting all current construction targets. Crews
recently completed most lane widenings from on-ramps to off-ramps and
shoulder sign construction. Crews have placed 77,000 of the total 352,300
tons of asphalt needed for the project, according to the City/County
Association of Governments of San Mateo County, or C/CAG. Crews have
finished nearly half of the construction of sound walls, with 20,650 of
47,210 square feet of sound wall work done. Construction is complete from
Dore Avenue to East Poplar Avenue and from Newbridge Avenue to Dakota
Avenue. Construction is underway from Third Avenue to Dore Avenue. The
Express Lanes Project is set to be completed in three parts. The first
began in March of 2019 and changed existing HOV lanes between the San
Mateo and Santa Clara County line and Whipple Avenue in Redwood City. The
second part is currently happening and involves constructing new lanes
from Whipple Avenue to I-380. Caltrans workers expect to complete the
second part in late 2022. The third part of the project is installing
tolling hardware and software to operate the new toll system. The toll
system is expected to be completed and ready to go live by the end of
2021. Caltrans officials are working on issuing an encroachment permit to
install the toll system, preparing equipment for installation, creating
toll pricing signs and licensing with cities for equipment.

In June 2021, it was reported that dynamic toll fees are coming to the new express
lanes on US 101 in San Mateo County starting at the end of 2021, with
maximum toll prices still yet to be determined. The San Mateo County
Express Lanes Joint Powers Authority announced it would establish toll
enforcement on the express lanes following June 11, 2021 board approval.
The first phase of the lanes opening from the Santa Clara County line to
Whipple Avenue in San Mateo County starts at the end of 2021, with the
second phase from Whipple Avenue to I-380 by the end of 2022. Matthew
Click, policy program manager for the San Mateo County Express Lanes Joint
Powers Authority, or SMCEL, said toll fees would be a minimum of 50 cents
per zone on the express lanes, with no maximum fee number set for a trip
or zone rate. Click said SMCEL would not know its maximum rate per zone
until it opens the lanes and sees initial toll rates. There are five toll
zones in each direction on the express lanes, averaging around 3 to 5
miles in length. Algorithms will determine toll rates through dynamic
pricing, changing based on demand and traffic patterns, with the goal of
keeping express lane traffic flowing smoothly. SMCEL manages the express
lanes and is a six-member joint powers authority consisting of three San
Mateo County Transportation Authority members and three City/County
Association of Governments of San Mateo County board members. The express
lanes project will create 22 miles of express lanes on US 101 from the
southern San Mateo County line to I-380 in South San Francisco.
Transportation officials have said it would reduce congestion, increase
the number of people who can travel, encourage carpooling and transit use
and improve travel times. SMCEL has worked since 2020 on various toll
policies and options. It has the authority to determine who will need to
pay a fee to use the lanes and how much that fee will be. A portion of the
fees will fund the equity program, which would allocate money to
historically underserved communities for better express lane access and
public transit use.

In January 2022, it was reported that South San
Francisco councilmembers have indicated a desire not to see a lane added
to a 9 mile stretch of US 101 that partially runs through the city, citing
increased pollution from vehicles that could affect nearby neighborhoods.
The proposed project would add managed lanes to the span, currently four
lanes wide from the I-380 interchange to the San Francisco/San Mateo
county line. The task could be carried out by either converting an
existing lane or by widening the freeway to accommodate a new lane. Adding
a lane, councilmembers said, would ultimately increase the amount of
people traveling on the thoroughfare, something that could have negative
effects for the adjacent downtown neighborhood. The managed lanes would be
implemented as high-occupancy vehicle lanes (carpool lanes) or express
lanes (similar to carpool lanes with the added option for lone drivers to
pay a fee for use). The lanes would join with express lanes currently
being built south of the I-380 interchange to Whipple Avenue in Redwood
City, and south of that, from Whipple Avenue to the southern county line
where an existing carpool lane is being converted to an express lane. The
agencies hope to finalize a design by 2025 and complete the project in
2027. The proposal is currently in the environmental scoping phase and
will next undergo environmental review and project approval, expected in
2023. A complicating factor that could limit the viability of converting a
lane is state law, which allows for converting an existing lane for
traditional carpool use but prohibits converting a lane to be used as an
express lane.

In February 2022, it was reported that the new express
lanes on US 101 from the Santa Clara County line to Whipple Avenue in
Redwood City were opening in mid-February 2022. The northern end of the
project is expected to be completed this year, extending these lanes up
from Whipple to I-380. The lanes lead directly into Express Lanes in Santa
Clara County.

In October 2022, it was reported that a soft opening
had taken place for the US 101 express lane section from Whipple Avenue in
Redwood City to I-380 in South San Francisco. The express lanes will be
open to vehicles with three or more passengers and motorcycles only from 5
a.m. to 8 p.m., Monday through Friday. The new express lanes will be open
to all vehicles during all other times. Full operations will start in
early 2023 once crews complete construction for signal operations. "By
email tolling" will not start until the official opening in 2023, with the
lane still operating as a HOV 3+ lane, rather than a general purpose lane.
The soft opening allows transit officials to examine traffic flow and
signal runs for carpoolers while also allowing the public to use it.

In March 2023, it was reported that the San Mateo
County US 101 express lanes from Whipple Avenue in Redwood City to I-380
in South San Francisco had opened for tolled usage by all FasTrak users.
The lane had a soft opening in October 2022, when fees were not charged
during the testing period, but the lanes are open for testing for 3+ HOV
users and commuter buses. Early March was when charges began for all with
a FasTrak transponder. There will be dynamic pricing throughout the
22-mile corridor in both directions, with the rules the same as the
southern section of the US 101 express lanes. Dynamic pricing means the
price to use the lane goes up or down depending on how crowded it is. A
system monitors the toll and raises or lowers it to keep traffic flowing.
The highest pricing depends on how far people are traveling and how much
traffic there is. An average toll is not always an accurate way to predict
pricing, but the average toll posted in the southbound direction in
November was $3.

With the opening of the lanes S of I-380, attention
turns to PPNO 0658M, the segment N of I-380. In May 2023, the CTC received
notice of a STIP amendment to delay the Right of Way (RW) phase from
Fiscal Year 2023-24 to 2025-26 for the US 101 Managed Lanes – Route 380 to SF County Line project (PPNO 0658M), in San Mateo County. The US 101 Managed Lanes – Route 380 to SF County Line project proposes to
construct managed lanes in both the northbound and southbound directions
of US 101 from 1 mile south of the US 101/Route 380 Interchange in San
Mateo County to the San Francisco County line. The delay for RW is due to
additional time needed to work with the San Francisco County
Transportation Authority to analyze and develop scenarios for a managed
lane facility in San Francisco County that will connect to the San Mateo
County managed lanes project. In addition, C/CAG has encountered
environmental document review delays caused by the requirement of the
Union Pacific Railroad (UPRR) to have an executed reimbursement agreement
in place prior to performing any preliminary engineering review during the
environmental phase. As a result, C/CAG requests a two-year delay to work
with the Department and UPRR to complete the environmental and engineering
phases before starting right of way work. In June 2023, the CTC approved
this STIP amendment.

In October 2023, it was reported that efforts to add an
express lane north of I-380 are one step closer to securing additional
funding, as the San Mateo County Transportation Authority Board approved a
resolution on Thursday, Oct. 5, that allows county staff to apply for
measures A and W grant funds to complete the current project phase. The
San Mateo 101 Managed Lanes Project North of I-380 is part of a larger
initiative that aims to decrease congestion in the county, particularly
along US 101. Construction on express lanes from the Santa Clara County
line to I-380 was finalized in March of this year, and the county is now
looking to expand the project up to the San Francisco county line. Express
lanes charge drivers a use fee depending on traffic conditions at the
time. Carpool users can use the lanes for free with a FasTrak Flex. The
plan consists of three project alternatives, which could construct a
brand-new lane, convert an existing lane into an express lane or simply
leave all lanes as they currently are. The project is still in its
nascency, and the grant funding being sought will completion of the second
phase, which includes an environmental review of all three alternatives.
The TA board had previously allocated $8 million for the current phase of
the project, but approximately $2 million in additional funding is now
needed to complete it. To finalize the grant application, the TA needs
additional approval from their governing body, which includes its Board of
Directors and the City/County Association of Governments of San Mateo
County Board of Directors.

US 101 Auxiliary Lanes - Route 85 (~ SCL 48.063) to Embarcadero Road (~ SCL 52.168)
In May 2010, the CTC approved amending the CMIA baseline agreement for the US 101 Auxiliary Lanes – Route 85 to Embarcadero Road project (PPNO 0483I) to: (1) Update the project scope by eliminating two segments of southbound auxiliary lanes and by extending the existing dual high occupancy vehicle (HOV) lanes in both directions of Route 101. (2) Update the overall project funding plan by shifting local funds by increasing Environmental (PA&ED) from $3,534,000 to $3,971,000, increasing Plans, Specifications, and Estimate (PS&E) from $7,182,000 to $8,180,000, and decreasing Right of Way (R/W) from $6,612,000 to $5,177,000. The current project scope consists of adding auxiliary lanes in each direction from Embarcadero Road to Route 85. Based upon traffic operations and geometric analyses performed during the completion of the environmental process, the selected preferred alternative excludes the following two auxiliary lane segments from the project scope: (1) The southbound auxiliary lane from south of the San Antonio Road Interchange to the point of existing auxiliary lane between the Charleston Road on-ramp and the Rengstorff Avenue off-ramp, has been excluded due to its undesirable merge conditions at the Charleston Road on-ramp. (2) The southbound auxiliary lane from the Rengstorff southbound on-ramp to the existing auxiliary lane, between the Old Middlefield on-ramp and Shoreline Boulevard, has been excluded because it would have created a non-standard merge condition for the Old Middlefield Way on-ramp and also would have resulted in the relocation of a roadway maintenance facility in this area. The savings resulting from the elimination of these two auxiliary lane segments will be utilized to extend the existing dual HOV lanes in both directions. Under the current conditions, a transition from dual HOV lanes to a single HOV lane occurs in both directions on Route 101 near the Route 101/Route 85 interchange. The forecasted traffic volumes predict that by 2015, the HOV lane demand will exceed the capacity of a single HOV lane for this segment of Route 101. The traffic operation analyses have concluded that the extension of the existing dual HOV lanes to a point just north of the San Antonio Road interchange will provide congestion relief on Route 101 in both directions.
In July 2010, the CTC approved for future consideration of funding a project that will construct auxiliary lanes, lengthen existing high occupancy vehicle lanes, and construct roadway improvements between Embarcadero Road and Route 85. The project is programmed in the Corridor Mobility Improvement Account and includes local funds. Total estimated project cost is $102,258,000, capital and support. Construction is estimated to begin in Fiscal Year 2010-11. The project differs from the baseline agreement in that it proposes to extend the existing dual HOV lanes in addition to the original auxiliary lanes originally proposed.
In January 2012, the CTC approved reducing the original CMIA allocation for construction by $9,191,000 (reflecting construction contract award savings), from $24,377,000 to $15,186,000, from the US 101 Auxiliary Lanes from University Avenue to Marsh Road project (PPNO 0658B) in San Mateo County. The contract was awarded on June 1, 2011.
In August 2011, the CTC approved funding $84,930,000 for the state-administered CMIA project to construct US 101 Auxillary Lanes from Route 85 to Embarcadero Road.
In August 2011, it was reported that the CTC approved $84.9 million in funding for construction of merging lanes on US 101 from Palo Alto to Mountain View.
In January 2012, the CTC approved reducing the original CMIA allocation for construction by $29,059,000 (reflecting construction contract award savings), from $73,850,000 to $44,791,000 from the US 101 Auxiliary Lanes (from Route 85 to Embarcadero Road) project (PPNO 0483I) in Santa Clara County. The contract was awarded on November 17, 2011
In May 2012, it was reported that the three-mile stretch of US 101 between Route 85 in Mountain View and Embarcadero Road in Palo Alto will be getting double HOV/Toll lanes. This project also includes the addition of merging lanes. The total cost will be $72 million ($56 million in state bonds and $16 million from VTA); $18 million below engineers' estimates. There are also plans to widen the southbound Oregon Expressway onramp, add a lane on the southbound Old Middlefield Way onramp and install meters at northbound Amphitheatre Parkway and San Antonio Road ramps. Estimated completion is late summer 2013.
In January 2014, the CTC approved for future consideration of funding a project in San Mateo County that will reconstruct the existing interchange at US 101 and Willow Road in the cities of Menlo Park and Palo Alto.
In July 2017, it was reported that the interchange between US 101 and San
Antonio Road (~ SCL 50.326) near Palo Alto is one of the interchanges that
will be rebuilt with money from the Measure B sales tax approved by Santa
Clara County voters last year and it could be on the fast track. The $35
million job will have design work done next year and construction between
San Antonio and Charleston could begin by late summer 2018.

Highway 101 Pedestrian/Bike Bridge Project at Adobe Creek (~ SCL 50.655)
In November 2017, it was reported that the Palo Alto
City Council has authorized construction of a pedestrian/bike crossing
over US 101, near the San Antonio Road bridge (~ SCL 50.655). The new
crossing, first proposed around 2010 and budgeted in 2017 at $16.21
million, will replace the seasonal Benjamin Lefkowitz underpass, providing
year-round access to the Palo Alto Baylands Nature Preserve, a regional
Bay Trail network east of US 101, and adjacent businesses and residences
in Mountain View and Menlo Park. It will also provide an alternate
connection between West Bayshore Road and East Meadow Drive via a new
Adobe Creek Reach Trail, which has not yet opened to the public. Although
the council unanimously approved the project, some members expressed
concern about the rising costs of the project. In 2011, for instance, the
cost for a basic crossing was estimated at roughly $6 million. A year
later the cost estimate climbed to $10 million and today it hovers above
$16 million, which is $2 million to $3 million over budget, according to a
staff report. The crossing is expected to be completed by spring 2020. THe
funding includes a $1 million contribution from Google. There are no
strings attached with the Google contribution; however, the city will be
reconfiguring the firm’s private parking lot at 3600 W. Bayshore
Road to accommodate a new access ramp. The landscape area around the lot
will also be improved and serve as a stormwater collection basin. The
project includes continuous lighting, benches, bike racks, trash
receptacles, drinking fountains and a dog hydration station, an overlook
area, bird-friendly features for swallow nesting and informational and
educational signage. Final approval came with the conditions that staff
pursue additional funding sources and explore sponsorship opportunities.
Along with the Google contribution, the project is being funded with $4
million from the Santa Clara County Recreation Fund and a $4.35 million
grant from the Metropolitan Transportation Commission. The remaining $6.86
million would come out of the city’s capital improvement fund, if
other funding sources aren’t acquired. The project is to return to
the council in January with an updated cost estimate and funding plan.
Construction is anticipated to begin in 2019 and be completed by spring
2020.

In December 2018, it was reported that there was a
milestone signing ceremony for the project on December 17, 2018. At the
ceremony, Palo Alto Mayor Liz Kniss was joined by Google COO for Real
Estate & Development, Mark Golanto sign a key public access agreement,
allowing the bridge’s western approach ramp to be located on
Google’s West Bayshore Road property. Representatives from Caltrans
and the Santa Clara Valley Water District also signed maintenance and
joint-use agreements, while State Assemblyman Marc Berman, State Senator
Jerry Hill, and others who have championed the project were on hand for
the ceremony. The bridge is part of Palo Alto’s 2014 Infrastructure
Plan and will span over US 101 from south Palo Alto to the Baylands,
providing a link for bike riders and pedestrians to access businesses and
recreation trails on both sides of the highway. The agreements signed are
needed to start bridge construction. A Santa Clara County Recreation
Trails Program grant will provide $4 million for the project, a One Bay
Area Grant Cycle 2 program fund grant will provide $4.35 million, plus $1
million is coming from Google- together this accounts for more than half
of the project’s $16 million budget. The Benjamin Lefkowitz
Underpass is the pedestrian/bike path that currently connects the two
sides, but it closes for several months each year due to Adobe
Creek’s seasonal flooding of the underpass area. Once the new
12-foot wide bridge is built, it will provide year-round access. Palo Alto
anticipates 74,000 trips will be made across the bridge annually once it
is completed. Groundbreaking is anticipated in Spring 2019.

In November 2021, it was reported that the new Adobe
Creak Reach Trail bridge over US 101 had opened, after a year and a half
of construction that included 13 million pounds of concrete, 1 million
pounds of structural steel and 7,000 feet of electrical and fiber optic
cable. The new overpass that will provide year-round access to the
Baylands, the new Adobe Reach trail and other outdoor amenities. Spanning
1,400 feet long between the West and East Bayshore Road landings with a
12-foot-wide pathway, the bridge replaces the Benjamin Lefkowitz
underpass, which was only open six months a year, on average, due to
seasonal flooding. The final price tag of the bridge was $23.1 million.
Funding came from several sources, including a $1 million grant from
Google and a $4.35 million investment the city is expected to receive from
the Metropolitan Transportation Commission's One Bay Area Grant Program.
During broad daylight, the bridge's most distinctive feature is the
rust-brown steel trusses above the highway and Adobe Creek. According to
Roy Schanbel, managing principal at Biggs Cardosa, the color can be
attributed to the self-weathering steel. The material is intended to rust
over time, he said, so that a protective coating is created and prevents
the bridge from further rusting. "It's supposed to look like that and it's
supposed to rust," Schanbel said. "It's earthy." At night, the frame of
the bridge blends into the night sky and mostly appears as a crisscross of
faint, dotted lights. Eggleston said that LED lights were installed in a
way to reduce the amount of light pollution and avoid disturbing the
surrounding wildlife. Throughout the walkway, for example, the LED lights
are pointed downward so that they will only serve to light up a pedestrian
or cyclist's path and nowhere else, Eggleston said.

In December 2016, the CTC authorized relinquishment of right of way in the city of Palo Alto along Route 101 on East Bayshore Road (between San Antonio and Embarcadero, 04-SCl-101-PM 50.7/51.2), consisting of collateral facilities. The City, by letter signed September 12, 2016, agreed to waive the 90-day notice requirement and accept title upon relinquishment by the State.
US 101 Auxilliary Lanes - Embarcadero Road (~ SCL 52.168) to Marsh Road (~ SM 3.587)
In September 2009, the CTC amended a project located on Route 101 in San Mateo and Santa Clara Counties. The current project will: a) Widen Route 101 to add auxiliary lanes in each direction from the Marsh Road Interchange in San Mateo County to the Embarcadero Road Interchange in Santa Clara County. b) Widen/modify various on/off-ramps at four interchanges within the project limits. c) Re-construct Ringwood Pedestrian Overcrossing and Henderson Underpass to accommodate the auxiliary lanes. d) Install Intelligent Transportation System (ITS) equipment within the project limits. The amendment eliminate the Henderson Underpass structure (which would have to be rebuilt anyway as part of an upcoming rail project), updated the funding plan, and split the project into three segments: Segment 1 (PPNO 0658B) – US 101 Auxiliary Lanes: Embarcadero Road to University Avenue; Segment 2 (PPNO 0658C) – US 101 Auxiliary Lanes: University Avenue to Marsh Road; and Segment 3 (PPNO 0658D) – US 101 Replacement Landscaping: Embarcadero Road Interchange to Marsh Road Interchange.
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $1,800,000 for High Priority Project #961: Construction of US 101 Auxiliary Lanes, Marsh Rd. to Santa Clara County Line.
In October 2009, the CTC approved for future consideration of funding a project in San Mateo and Santa Clara Counties will construct auxiliary lanes in each direction on Route 101 from the Embarcadero Road Interchange in the city of Palo Alto (Santa Clara County) to the Marsh Road Interchange in the city of Menlo Park (San Mateo County). The project is programmed in the Corridor Mobility Improvement Account and the 2008 State Transportation Improvement Program and includes local funds. Total estimated project cost is $111,389,000, capital and support. Construction is estimated to begin in Fiscal Year 2010-11. The scope as described for the preferred alternative is consistent with the project scope set forth in the approved baseline agreement. (what's odd about this is that it seems to be the project they amended the previous month). In May 2010, it was reported that San Mateo County transportation officials approved $30 million for this project. The funding will allow the Caltrans to start the four-mile freeway-widening project. The state expects to seek construction bids later this year and start building in early 2011. The work is expected to last through 2013. The project is part of a larger Caltrans effort to add auxiliary lanes to the busy freeway. The agency is currently adding auxiliary lanes between Millbrae and San Mateo, and there are plans to add the lanes south of Embarcadero to Route 85. The project will also include the installation of better metering lights at nearby on-ramps, which will be widened to include carpool-lane entrances onto the freeway. Crews will have to reconstruct the Ringwood Avenue pedestrian bridge over US 101 in Menlo Park and widen the Hetch Hetchy Aqueduct bridge. Caltrans has already secured $74.2 million from two separate state funding pots for the project, plus $1.8 million from the federal government. The county had already committed $6.9 million, and its latest contribution will bring the funding total for the project to $113 million. Construction broke ground on this project in July 2011.
In October 2011, the CTC approved funding around $3.8 million toward creating auxiliary lanes along US 101 between Embarcadero Road and University Avenue.
San Francisquito Creek Bridge Replacement (~ SCL 52.543)
In May 2012, the CTC approved for future consideration of funding a project in Santa Clara County that will replace the San Francisquito Creek Bridge on Route 101 at San Francisquito Creek, which divides the Cities of East Palo Alto and Palo Alto, and the Counties of San Mateo and Santa Clara. The project is programmed in the 2012 State Highway Operation and Protection Program (SHOPP). The total estimated project cost is $15,676,000 for capital and support. Construction is estimated to begin in Fiscal Year 2013- 14. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2012 SHOPP.
In June 2015, it was reported that work had begun on the San Francisquito Creek replacement
project. The project will remove and replace the US 101 bridge over the
San Francisquito Creek, at the border of San Mateo County and Santa Clara
County. The project will also remove and replace the West Bayshore Road
and East Bayshore Road bridges over the creek. The bridge over San
Franciquito Creek was originally constructed in 1931 and widened in 1957
to include the frontage roads on either side of the freeway. Over the
years, the bridge has deteriorated due to wear and tidal action. Based on
structural inspections, a recommendation to replace the bridge was made in
2001 and reconfirmed in subsequent inspections. The new bridges will
provide increased hydraulic capacity to be consistent with the
improvements proposed by the San Francisquito Creek Joint Powers
Authority. The new bridges will have less maintenance cost and provide
protection from flooding. The project was be advertised in early 2015. It
is expected that a contractor would begin construction in April 2015.
Construction is expected to occur over three seasons with most of the work
taking place from June to October due to restricted work windows in the
creek. Work in 2015 focused on demolition of existing bridges and
soundwalls. The project was expected to be completed in 2018.

Newell Avenue (E. Palo Alto) Pedestrian Overcrossing (~ SM 0.467)
In October 2016, the CTC approved for future consideration of funding a project that will construct a Class I Pedestrian/Bicycle Overcrossing Structure over US 101 to provide a direct connection between the south side and north side of US 101 in East Palo Alto. Improvements will also include a sidewalk, bicycle signage, striping along West Bayshore Road and a new pedestrian crossing will be added at Newell Avenue. The Project is estimated to cost $9,800,000 and is fully funded through construction with Local Funds ($1,200,000) and Active Transportation Program Funds ($8,600,000). Construction is estimated to begin in Fiscal Year 2016/17.
In May 2019, it was reported that the new overpass,
connecting at Newell Road and Clarke Avenue, had opened. It was designed
to unite East Palo Alto neighborhoods and improve access for residents to
schools, shops and parks, city officials said. Construction of the
$14-million project took 18 months from start to completion. The city
received $8.6 million from California’s Active Transportation
Program and the remaining balance came from a combination of local funds.
The bridge’s pedestrian enhancements include LED lighting and a
12-foot-wide walkway. It cuts the crossing distance over US 101 by
one-third of the distance from 1.5 miles to a half-mile, city officials
said.

University Avenue-US 101 Interchange Improvements Project (04-SM-101 0.8/1.1)
In December 2021, it was reported that the San Mateo
County Transportation Authority Board of Directions allocated $8 M towards
the City of East Palo Alto’s latest pedestrian/bicycle overcrossing
along the north side of the US 101/University Avenue overcrossing. The
estimated total project cost is $15 M. The project will relieve an
interchange bottleneck at University Avenue and US 101. The project will
also reduce intersection delay along University Avenue at both Donohoe
Street and Woodland Avenue. The southbound ramp improvements will reduce
queue lengths in both the AM and PM peak periods. Bicycle and pedestrian
safety will be improved with a dedicated overcrossing that will eliminate
bicycle and vehicle weaving conflicts on University Avenue. Combined,
these improvements will create separated, comfortable facilities for
people walking and biking to access nearby schools, business centers,
retail areas, and transit stops.

Pedestrian Overcrossing will improve the connectivity for pedestrians and
bicyclists between the east side and west side of East Palo Alto. The
project will construct a Class I shared pedestrian and bicycle path from
Donohoe Street on the east side of East Palo Alto to Woodland Avenue on
the west side of East Palo Alto. The path includes a new.
4-span, pedestrian overcrossing bridge just north of the existing
University Avenue Bridge over US 101. Improvements to US 101 will be
included in the project. The northbound US 101 off-ramp to
University Avenue will be re-aligned. The southbound US 101 off-ramp
will be widened at University Avenue to create two dedicated right turn
lanes and two dedicated left turn lanes. The total budget for the
project, including design and construction management is $14 million
project. The project funding is provideed by the San Mateo County
Transportation Authority Measure A and Measure W, a Stanford Recreation
Mitigation Grant, State SB1 / LLP funds, and Federal HPP funds.
Construction should start Feb/Mar 2023.

anticipated benefits of this project include improving public safety,
providing access to key destinations, traffic calming, and increasing
walking and bicycling in the project area.

In December 2022, it was reported that the
pedestrian-bicycle overcrossing over US 101 at University Avenue in East
Palo Alto broke ground in early December 2022. The University Avenue/101
Pedestrian Overcrossing Project, which will parallel but be separate from
the existing bridge, will create safe access to the east and west sides of
East Palo Alto and neighboring Palo Alto after decades of separation by
the busy freeway. The $14.6 million project, which is the second of two
pedestrian overpasses to join the city — the first is the Clarke
Avenue bridge near the Ravenswood 101 Shopping Center — has been
more than a decade in the works. It will span 12 feet wide connecting the
east side along East Bayshore Road to a route in the University Circle
business development near the Four Seasons Hotel Silicon Valley. The
project has been granted $4.8 million from Measure A funds through the San
Mateo County Transportation Authority, $771,000 in federal earmark funds
and $1 million from the Stanford Recreation Mitigation Grant, which was
approved by the Santa Clara County Board of Supervisors. The city was
recently awarded $5.7 million through Measure W and $2.3 million through
the State Local Partnership Program to fill the construction funding gap.
The project is scheduled to begin construction this spring and be
completed by winter 2024. The existing overpass, perhaps the oldest
crossing over US 101 in the county, will eventually be replaced. The
upgrade could take 15 or 20 more years and would likely cost upward of $83
million — the cost the California Department of Transportation
(Caltrans) paid to replace the overpass at Willow Road in Menlo Park.
Instead, city, county, state and federal officials came up with a
replacement that would be separate from the existing bridge so that it
could eventually be torn down without impacting pedestrian and bike
access. The new bridge would also open access to mothers with baby
strollers and people with assisted devices such as wheelchairs as well as
foot and bike traffic.

US 101 / Willow Road Interchange (Menlo Park) (~ SM 1.885)
In March 2013, it was reported that Caltrans, in
partnership with San Mateo County, East Palo Alto and Menlo Park, plans to
reconstruct the current full cloverleaf interchange of US 101 and Willow
Road to "address deficiencies impacting motorists, bicyclists, and
pedestrians by eliminating traffic weaves and providing adequate space for
vehicles to stack on freeway off-ramps," according to the agency. The six
designs under consideration -- four using variations of a partial
cloverleaf, and two using a diamond configuration -- range in cost from
$38.2 million to $54.9 million for construction costs and right-of-way
acquisitions. A half cloverleaf design, labeled "1B" in the staff report
with an estimated price tag of $42.5 million, appears to be the leading
contender after consultants reviewed the designs. The city of East Palo
Alto has also expressed its support for that configuration. One key
request from Menlo Park was to evaluate the feasibility of adding a median
bike lane along Willow Road, through the interchange. The staff report
states that a median lane presents some safety issues, as drivers aren't
used to it and it exposes bicyclists to traffic on both sides at
intersections. The design team concluded that the option wasn't viable.
(Source: The Almanac, 3/2620/13)
In June 2015, it was reported that the City of Menlo
Park has signed on as an official sponsor of the interchange project at US 101 and Willow Road. The city hopes to find and secure the $65 million
needed to construct a new interchange at Willow Road. The project has been
in the works for more than two decades. In 2009, county residents passed
the Measure A sales tax measure, which funds countywide transportation
improvements and will allow Caltrans and the San Mateo County
Transportation Authority to design and construct the interchange. The new
design features seismic updates and widening of the bridge to accommodate
pedestrian and bicycle facilities that don't now exist. Construction is
slated to begin next spring and will last roughly 2½ years. Though
traffic will be affected during construction, motorists still will be able
to travel in both directions along Willow Road. As project sponsor, Menlo
Park will be responsible for doing community outreach, rallying political
support, ensuring there's enough funds to cover the construction phase and
helping coordinate efforts. Caltrans and the Transportation Authority
would be in charge of construction because the interchange is owned and
controlled by Caltrans.

In October 2015, it was reported that the San Mateo
County Transportation Authority allocated $56.4 million toward Menlo
Park’s US 101/Willow Interchange Project (for the 3 year Measure A
cycle). That will convert the existing full cloverleaf into a partial
cloverleaf interchange, replace the existing overcrossing with additional
lanes as well as sidewalks and enhanced bike paths, according to a TA
staff report.

In February 2017, it was reported that a member of
Atherton’s Transportation Commission has prompted Menlo Park to take
another look at a $70 million project to rebuild the Willow Road/US 101
interchange. The Caltrans-led project, which is being paid for through
county Measure A funds, will replace the existing interchange with a new,
wider bridge, and the current “full cloverleaf” will be
replaced by a “partial cloverleaf.” Sidewalks and bicycle
lanes separated from vehicular traffic will be added to both sides of
Willow. The project is already under way, with utility work causing
periodic roadway closures, and is expected to last two years. Actual
construction of a new bridge isn’t expected to begin until the
summer. Atherton's complaint is that the project won’t make the
roadway any safer, as Caltrans has stated, but will worsen congestion.
They propose instead that Measure A funds should be diverted to fixing the
Willow Road and University Avenue intersections with Bayfront Expressway,
where the congestion primarily originates. The Atherton commission member
believes the change to a partial cloverleaf will lead to longer queues and
could lead to more collisions, saying that has been the case at the US 101
interchanges at Marsh Road and Hillsdale Boulevard after they were rebuilt
with partial cloverleafs. This member also doubts the need to rebuild the
overpass to make it seismically sound or to make the Willow section safer
for bicyclists and pedestrians, two aspects the city has cited for backing
the project. He suggests that a bike bridge be built along US 101
somewhere between Willow and University, and Willow be left alone.

In October 2015, it was reported that the San Mateo
County Transportation Authority allocated $2.65 million to help add
vehicle lanes, sidewalks and bikeways to the Woodside Road/US 101

In July 2017, it was reported that a plan to ease
congestion at a Redwood City highway interchange moved into the design
phase this week. The City Council on Monday authorized staff to pay AECOM
Technical Services up to $7.9 million to design improvements for the US 101/Route 84 (Woodside Road) interchange, which involves widening Woodside
Road to add new lanes, building new ramps to and from US 101 and adding
sidewalks and bicycle lanes. The council also authorized paying Krupa
Consulting up to an additional $335,000 to continue managing the project.
The purpose of the project is to alleviate peak-hour congestion at the
interchange and reduce traffic at local street intersections of Woodside
Road with Veterans Boulevard, Broadway, Bay Road, Seaport Boulevard,
Blomquist Street and East Bayshore Road. The city, as sponsor of the
interchange project, is responsible for completing the first phase of
design, set to begin next month and continue through Aug. 31, 2019. AECOM
will design widening Woodside Road from four to six lanes, plus turn
pockets; lowering Woodside an additional 6 inches to boost vertical
clearance at the US 101 undercrossing to 15 feet; reconstructing ramp
connections between Woodside and US 101, replacing a northbound US 101
ramp to connect with Seaport at a new signalized intersection and
constructing flyover ramps between Veterans and US 101; eliminating the
five-legged intersection at Woodside and Broadway; adding a series of new
sidewalks and bike lanes throughout the project area; and adding
high-occupancy vehicle lanes to US 101 ramps. The project doesn’t
require the city to spend any funds out of its operating budget on the
design phase. The work is funded through the San Mateo County
Transportation Authority Highway Program Grant, which had a balance of
$8,044,880 as of May 31, and more than $1.5 million in traffic mitigation
fees collected from two commercial developments recently approved in the
Woodside corridor.

San Carlos / Holly St. Interchange (101 SM 8.406)
In October 2015, it was reported that the San Mateo
County Transportation Authority allocated $10.7 million for San
Carlos’ US 101/Holly Street Interchange Project (101 SM 8.406),
which will convert the existing full cloverleaf to a partial cloverleaf
interchange while adding new and widened bike lanes. The city’s
request for another $3 million to construct a separate pedestrian/bicycle
bridge was denied, as it wasn’t eligible under the conditions of the
TA’s highway program, according to the report.
(Source: San Mateo Daily Journal, 10/2/2015)
In December 2017, it was reported that an effort to
reduce congestion and improve safety on the Holly Street and US 101
interchange in San Carlos took a leap forward recently when the San Mateo
County Transportation Authority approved funds needed to make up a gap in
the project’s funding pegged earlier this year. Plans to update the
existing interchange with a new design and add a pedestrian and bicycle
bridge just south of it had been on hold for months before the agency
supplemented a previous grant with another $3.8 million commitment to the
project, said Vice Mayor Cameron Johnson. Also on the board of the
Transportation Authority, Johnson said the interchange’s current
design, which forces cars coming onto and off freeway ramps to weave
together, has created slowdowns and raised safety concerns for those
traveling through the city. Redesigning the interchange’s cloverleaf
entrances and exits and creating a new connection for pedestrians and
bicyclists is expected to cost a total of $35 million, adding that efforts
to design and review the environmental effects of the project also
factored into the cost. $24 million has been committed from outside grant
funds and that the city is expected to commit $11 million to the project
when the council discusses the project in February 2018. Should the
council agree on the final amount coming from the city coffers at that
meeting, the project could break ground as early as June or July 2018.
Replacing two of the four cloverleaf entrances with additional lanes and
traffic signals at Holly Street are among the changes aimed at improving
the safety of drivers, bicyclists and pedestrians traveling on a major
city thoroughfare to get to US 101 and office buildings east of it.
Creating a separate bridge for bicyclists and pedestrians might encourage
workers and residents with concerns about using Holly Street for their
commutes to look at other options. Together with a separate project to
install a new traffic signal at East San Carlos Avenue and Industrial
Road, the interchange improvements would chart a path for bicyclists from
the San Carlos Caltrain station to the office buildings on the east side
of US 101, as well as to the 204-room Landmark hotel being constructed
near the new signal. The project should take an estimated 18 months once
ground is broken, and because the construction will mostly be taking place
above or near the highway, some night work will be necessary. There may be
congestion near on- and off-ramps during construction but expected regular
traffic patterns on Holly Street to continue.
(Source: San Mateo Daily Journal, 12/18/2017)
In February 2018, it was reported that, although San
Carlos officials weighed concerns about how the Holly Street and US 101
interchange project might affect local streets, they opted not to delay it
any further when they approved another $7 million toward the major
infrastructure overhaul. The council voted 4-1 to approve the additional
funds, which are part of the city’s match to the nearly $21 million
committed by several other agencies, including the state, the Metropolitan
Transportation Commission and the City/County Association of Governments.
Expected to cost more than $30 million, plans to update the existing
interchange with a new design and to add a pedestrian and bicycle bridge
just south of it had been on hold until the San Mateo County
Transportation Authority supplemented a previous grant with close to $4
million in December.

A new pedestrian/bike bridge is coming on US 101 at Hillsdale Boulevard
(~ SM 11.135). Local officials envision this $35 million project as a key
link to encourage users to get out of their cars and not contend with
traffic. It will allow a much safer way for pedestrians and bicyclists to
get from the Hillsdale Boulevard interchange while connecting the bike
lanes from the Hillsdale Caltrain station to Foster City and neighborhoods
east of US 101. This bridge is the last significant segment of a 1.2-mile
bike lane between the Hillsdale station and the Los Prados and Lakeshore
neighborhoods east of US 101. The existing overcrossing is the only one in
the area with the nearest crossing approximately 2 miles to the north at
19th Avenue and the Belmont overcrossing more than 2.5 miles to
the south.

US 101/Route 92 Interchange Improvements (~ SM 11.885)
In June 2010, it was reported that studies are
beginning to improve the US 101/Route 92 interchange. Officials from three
local transit agencies are splitting a $450,000 study that by the end of
Summer 2011 should map out why cars move so slowly through the area, and
what can be done about it. The purpose of the study is to figure out if
there are any quick and easy fixes for operational problems in the
interchange. C/CAG, MTC and the county Transportation Authority will each
pay $150,000 to fund the study.
(Source: Oakland Tribune, 6/9/2010)
In March 2016, it was reported that state funding for
improvements to the US 101/Route 92 interchange that backs up traffic in
San Mateo has been eliminated. Members of the Metropolitan Transportation
Commission expressed frustration but approved a list of cuts, including
the one above. Funding may not be available until 2021.
(Source: SM Daily Journal, 3/28/2016)
In January 2018, it was reported that short- and
long-term ideas for the US 101 / Route 92 interchange are taking shape as
an early round of funding to consider options is coming together. The San
Mateo County Transportation Authority, or TA, is leading the project that
involves working with Caltrans, the City/County Association of
Governments, and the cities of Foster City and San Mateo. The project may
also align with fast-moving plans to create managed lanes across a San
Mateo County stretch of the congested US 101. Essentially, one of the
longer-term proposals is to construct new overpasses that would give
carpoolers and toll payers on Route 92 direct access to the managed lanes
in the center of US 101. Shorter-term ideas include widening certain
intersection ramps, reconfiguring lanes and eliminating the problematic
weave between commuters heading toward the San Mateo-Hayward Bridge. While
still early, nearly $3 million is being sought to prepare two documents
that will outline the scope of the longer-term “Direct Connector
Project” and the shorter-term “Interchange Area Improvements
Project.” That expense doesn’t include the environmental,
design or construction phases that cumulatively could cost more than $150
million. Suggested short-term improvements could happen in the next three
to five years. Alternatives include increasing capacity by adding a
carpool lane on the ramp from westbound Route 92 to southbound US 101.
Another option is to modify the Hillsdale Boulevard exit from northbound
US 101 to increase capacity and avoid spillover onto the freeway,
according to documents submitted to the TA. One proposal that includes
short- and long-term improvements is to add another lane on eastbound
Route 92 between US 101 to Mariners Island Boulevard. The goal is to
eliminate the short weaving distance between drivers from both directions
on US 101 trying to merge with others headed toward the bridge. The other
long-term suggestion is to create a quicker route for carpoolers by
creating new “connectors” or overpasses, from westbound Route 92 to both directions on US 101. That improvement would feed into the US 101 Managed Lanes Project, which suggests squeezing in a new lane in each
direction on the freeway. Located in the center, the express lanes would
be free for carpoolers with three people, and open to others willing to
pay a toll. That $593 million project is in the environmental review phase
with construction aiming to begin May 2019, according to Caltrans.

In May 2021, it was reported that local transit
agencies have begun public outreach for the US 101/Route 92 Short
Term Area Improvement Project, which will provide ramp and merger
improvements to four highway areas in San Mateo and Foster City. The
project would provide immediate low-cost construction options to improve
local ramp access from US 101, reduce weaving cars and improve overall
safety. Four improvement areas are being considered for construction
fixes. Area improvement one focuses on the westbound Route 92 to
southbound US 101 loop connector and would widen the loop connector ramp
and add a lane to increase capacity. Improvement two is for eastbound
Route 92, which seeks to improve heavy traffic and increase merging time.
It would eliminate the inside merge between eastbound Route 92 and
southbound US 101 and shift the existing merge points, although it would
not add a lane. Improvement three is to the southbound US 101 to westbound
Route 92 ramp. It would realign the Fashion Island Boulevard off-ramp and
segregate the eastbound and westbound Route 92 ramps to prevent illegal
motorist crossings. Improvement four addresses the northbound US 101 to
Hillsdale Boulevard exit ramp. It would widen and restripe the northbound
US 101 off-ramp, extend the eastbound through lanes through the northbound
US 101 and Hillsdale Boulevard intersection and realign the northbound US 101 loop on-ramp. Construction is estimated to start in April 2023, with
completion to be determined. The project total is estimated to be $28.6
million. If funding is not available for all four improvement areas,
Caltrans staff said each part could be constructed individually and would
be dependent on funding available.

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $3,000,000 for High Priority Project #525: Construct US 101 Auxiliary Lanes from 3rd Ave in the City of San Mateo (~ SM 13.456) to Millbrae Ave in Millbrae (~ SM 17.93).
San Mateo / Poplar Ave Interchange (~ SM 14.323)
With respect to the Route 92/US 101 interchange, there is more information in the draft EIR from 1979. Back in 1979, the section of Route 92 had an 0.7mi freeway gap, with an at-grade signalized intersection. The EIR concerned connecting freeway-to-freeway connectors (each replacing an existing ramp loop); reconstructing portions of the existing interchange; and building two new bridges across the Marina Lagoon. There were two alternatives under consideration. Alternate A is completion of the Route 92 freeway and reconstructing the interchange by replacing the loopramps in the southwest and northeast quadrants with direct freeway-to-freeway connections The loop ramps in the southeast and northwest quadrants would be structurally upgraded along with other parts of the interchange which are now temporary construction The nonfreeway section of Route 92 within the project limits would be reconstructed to freeway standards. This construction will include building two new bridges over Marina Lagoon. Alternate B is completion of the Route 92 freeway and reconstruction of the interchange by replacing all four loop ramps with direct freeway-to-freeway connections The gap in the freeway section of Route 92 will be completed in the same way as in Alternate A. The EIR notes that the Route 92/US 101 interchange was originally planned as a direct without loop ramps freeway-to-freeway interchange. This is the design of the interchange that is in the freeway agreement executed in 1967 between the City of San Mateo and the State of California. It was planned to construct the Route 92 freeway in this area and the interchange with Route 101 in a series of projects. This was necessary because of financing considerations and because this type of staged construction provided a good way to handle the detours and rerouted traffic. As part of this construction portions of the interchange and the segment of Route 92 connecting the interchange to Mariners Island were built on a temporary alignment. This portion of the staged project was constructed between 1967 and 1971. The temporary section of Route 92 includes the bridge over Marina Lagoon, a second temporary bridge spanning an adjacent lagoon, and an undivided section of highway that has a sharply curving alignment. Three structures of the interchange were built on temporary wood testle supported construction; these are the loop ramp in the southwest quadrant, the loop ramp in the southeast quadrant, and the connection between the permanent elevated section of westbound Route 92 and the temporary section of roadway leading to the top of the existing overcrossing. Alternative A was chosen to provide a lower cost alternative. Under Alternate A the interchange would be completed and the gap in the freeway portion of Route 92 would be closed as follows:
The EIR notes that Route 92 will be completed as a
four lane throughout the project. However because it necessary to provide
for the many merging and movements, there are locations where the ramps
freeway sections have increased roadway widths, and most of the freeway
within the project limits is wider than a standard section of four lane
freeway. The completed interchange will have three levels. The levels are
the two direct connections between Route 101 and Route 92. These
connections cross the interchange structures at a maximum height of 55'
above the ground.
(Source: Draft EIR Route 92 Gap Completion, 2/12/1979)
In February 2010, it was reported that the City of San
Mateo has started work to improve the US 101 intersection at Poplar
Avenue. The four-way intersection at Amphlett Boulevard features stop
signs in three directions, while motorists coming off the freeway travel
without stopping. In some cases, drivers are forced to make left turns or
enter US 101 while cars speed off the freeway in their path or turn in
front of them. The interchange has a much higher rate of
accidents—in fact, 37% more! City officials are working on options,
and hope to narrow down potential fixes through the public works
commission. The city has a $150,000 fund to complete the planning.
Currently, the only ideas on the table came from a November 2004 study,
and include included adding a median in Poplar to restrict turning access,
eliminating the interchange altogether or moving it north to the Peninsula
interchange, which provides access only to northbound US 101. However, the
option to move the onramp to the Peninsula interchange will be unlikely,
as Burlingame officials would have to add a lane to the street and have
indicated they would not be willing to do so. Further, if the Poplar
interchange were to be eliminated, the bulk of the traffic for drivers
trying to enter or exit southbound US 101 would move to the Third and
Fourth avenue junction, which would result in unacceptable levels of
traffic.

In June 2015, it was reported that after ditching
previous efforts due to the high cost of securing properties through
eminent domain, San Mateo and Caltrans officials are forging ahead with
multi-million dollar projects aimed at improving safety and traffic flow
at the city’s key intersections to US 101 at Poplar and Peninsula
avenues. The city has released a Project Study Report that outlines two
conceptual designs for creating a southbound on- and off-ramp at Peninsula
Avenue. Now, city officials will seek $2.5 million to conduct an
environmental review of the potential changes before any construction will
begin. The proposal, which stems from high accident rates at the Poplar
Avenue intersection, has also raised concerns among Burlingame residents
who fear their neighborhood bordering the project site would be impacted
by increased traffic. San Mateo is south of Peninsula Avenue and
Burlingame is to the north. In the short term, the city has already
planned improvements along Poplar Avenue such as installing a median to
deter cross-traffic from Amphlett Boulevard and Idaho Street. But
ultimately, Caltrans and San Mateo officials are considering closing the
intersection and creating a full access interchange to US 101 at Peninsula
Avenue to the west and Airport Boulevard to the east. After more than a
decade of planning, the city anticipates starting construction early next
year by installing a median along Poplar Avenue that would span from US 101 through Idaho Street. The improvements would ease cross traffic by
only allowing right turns to be made from drivers heading either direction
toward Poplar Avenue from Amphlett Boulevard and Idaho Street. The
Peninsula Avenue interchange project is in a much earlier stage.
Currently, there are no southbound on- or off-ramp from Peninsula Avenue;
instead, drivers seeking to merge onto US 101 are directed down Amphlett
Boulevard to enter from Poplar Avenue. The proposed project would keep the
northbound on- and off-ramps from Airport Boulevard to the east of the
freeway. The proposed alternatives would both require the city to secure
some right-of-way from several neighboring apartment and commercial
buildings along Amphlett Boulevard, according to the study. The second
alternative — a partially spread diamond interchange that has a less
pronounced curve as compared to the tight diamond interchange —
would require the complete removal of several existing properties.
Preliminary cost estimates predict the first alternative could cost about
$56 million while the more invasive alternative two could run up to $71
million, according to the study. The environmental review period will take
about a year and a half before a preferred alternative is chosen. If
everything goes smoothly, construction could begin in late 2021 and finish
in 2023.
(Source: San Mateo Daily Journal, 6/24/2015)
In January 2021, it was reported that San Mateo city
officials have provided updated information about the US 101/Peninsula
Avenue Interchange Project. The project would address long-term safety and
traffic operations and reduce travel times within the Peninsula Avenue
interchange area for San Mateo and Burlingame residents. It would include
improved bicycle and pedestrian travel options on Peninsula Avenue from
just west of North Humboldt Street to North Bayshore Boulevard. It would
relocate the existing US 101 southbound on- and off-ramps from East Poplar
Avenue to Peninsula Avenue, creating a single, full-access interchange at
Peninsula Avenue and Airport Boulevard. Poplar Avenue’s ramps would
close, as they do not meet current standards and causes traffic
congestion. The city is moving the southbound ramps to Peninsula Avenue
because it has two lanes in each direction, no parking or driveways and
has shoulders and bike lanes, all advantages over East Poplar Avenue. San
Mateo has two options for the design, a spread diamond interchange or a
tight diamond interchange alternative. The tight diamond interchange would
have closer spaced ramp intersections and was proposed to minimize
right-of-way impacts, or the need to acquire private property. Both
alternatives would also involve local road improvements and parking
changes in some surrounding areas, like North Amphlett Boulevard and
Peninsula Avenue. The city has been interested in improving safety at the
East Poplar Avenue off-ramps for several years and began a traffic study
and stakeholder engagement in 2017. The project is currently in the
environmental studies and preliminary engineering phase, expected to be
finished by May 2022. It focuses on traffic analysis, getting public
input, drafting an environmental document through a public process and
getting the final environmental document and overall project approval by
Caltrans. The city will be starting the California Environmental Quality
Act review process in a couple of months, with a CEQA scoping meeting
expected to be held in April. An environmental document would be available
for public review and comment in late 2021. The three primary partners are
San Mateo, the project sponsor, the San Mateo County Transportation
Authority, the funding partner, and Caltrans, responsible for reviewing
the environmental process and approving the project. San Mateo is
responsible for moving the project forward and obtaining funding for the
project, said Matthew Zucca, deputy director of Public Works. San Mateo
will work with Caltrans to select a preferred design and produce a final
environmental document. The city currently does not have funding for
subsequent project phases, which could cause some delay from the May 2022
phase completion date into the project design phase. The two final phases
are the project design and right-of-way acquisition phase and the
construction phase. The city will likely have a property acquisition
process if the project is approved. Both proposed alternatives could
affect some commercial property structures along North Amphlett Boulevard.
The spread diamond right-of-way alternative could affect the structure of
the Bayview Apartments parcel on North Amphlett Boulevard. The city said
it would focus on negotiating with properties to avoid eminent domain. The
soonest the property acquisition phase could start is May 2022, following
project approval.

US 101 / Broadway Interchange - Burlington (~ SM 16.612)
In August 2010, it was reported that detailed plans
have been released to replace the interchange at Broadway in Burlingame,
which is used by about 33,000 drivers daily. The $73 million project
includes a new seven-lane overpass across the freeway north of the
existing four-lane crossing. Unlike the current bridge, which connects
both sides of the freeway with a winding road requiring turns, the new
overpass will be a straight shot connecting Rollins Road to the west with
Bayshore Highway to the east. Airport Boulevard would move 100 feet to the
north to connect to the overcrossing, requiring the demolition of the 76
Phillips Conoco gas station at 1200 Bayshore Highway and its adjacent
parking lot. As many as three additional businesses near the freeway also
could lose their properties. The current mazelike setup, which includes 19
approaches and connections to the freeway, will be made simpler, and all
the onramps and offramps will be replaced. With the release of the state
environmental report from Caltrans -- which is partnering with the city of
Burlingame and the San Mateo County Transportation Authority on the
project -- the biggest remaining obstacle is funding. The city expects
about half the money to come from the county's half-cent transportation
sales tax. City officials also have secured a $4 million grant from the
Metropolitan Transportation Commission and plan to set aside $8 million in
proceeds from Burlingame's recent 2 percent hotel tax hike, although the
city has only earmarked $500,000 toward the project so far. Burlingame
Public Works Director Syed Murtuza said the city has been asking the
federal government to make up the difference. With environmental
clearance, it should be easier to convince politicians the plan is ready
for construction.

In May 2011, the CTC approved for future consideration of funding a project that will construct roadway improvements including the replacement of the Broadway overcrossing. The project is not fully funded. The project is currently programmed in the 2010 State Transportation Improvement Program for project development in the amount of $8,218,000. Total estimated project cost is $74,500,000 for capital and support. Depending on the availability of funds, construction is estimated to begin in Fiscal Year 2014-15.
In October 2011, the CTC approved for future consideration of funding the above project: Reconfigure the existing US 101/Broadway interchange in the city of Burlingame. (PPNO 0702A) This project in San Mateo County will reconstruct the US 101/Broadway Interchange in the city of Burlingame. The project is not fully funded. The project is programmed in the 2010 State Transportation Improvement Program for Project Development only. Total estimated project cost is $74,500,000. Construction is estimated to begin in Fiscal Year 2013-14. The scope as described for the preferred alternative is consistent with the project scope programmed by the Commission in the 2010 State Transportation Improvement Program. A copy of the MND has been provided to Commission staff. The project will mitigate potential impacts to wetlands and waters of the U.S to a less than significant level. Potential impacts to wetlands in the project area will be mitigated by purchase of mitigation bank credits and other methods determined through consultation with the U.S. Army Corps of Engineers. As a result, an MND was completed for this project.

Adopted 3/25/2020)
In August 2022, it was reported that plans for a new US 101 overcrossing for cars, bikes and pedestrians near the Produce Avenue
exit in South San Francisco cleared a major hurdle in July 2022 with the
release of the project’s draft environmental impact report. The $111
million project, first proposed in 2012, aims to improve access to the
industrial area east of US 101, which continues to see new developments.
It would be the city’s fourth east-west crossing of the highway, and
the only with dedicated bicycle lanes. If all goes to plan, construction
will begin in 2025 and wrap up in 2027. The bridge would extend from the
intersection of South Airport Boulevard and Utah Avenue over the highway
to reach San Mateo Avenue, creating a new three-way intersection.
Additionally, the intersection of San Mateo Avenue, Produce Avenue and
Airport Boulevard including the southbound foot ramp would be upgraded to
improve safety for pedestrians and cyclists. San Mateo Boulevard’s
northbound lanes from the Utah Avenue to the above intersection would be
restriped to create two lanes where there is currently just one. The area
east of the highway that the project would serve is among the Bay
Area’s fastest growing employment districts, with more than 13
million square feet of office and research space slated to be added in the
next 20 years, expected to double employment in the area to roughly
55,000, according to the environmental report. The area on the west side
of the highway also has seen considerable residential growth recently and
more is on the way. The project will require the removal of an IHOP
Restaurant and a commercial warehouse, which houses Bay Badminton Center,
SF Elite Volleyball Club and Golden Gate Moving Company. The overpass
would primarily pass over a private parking lot serving the airport, which
would remain. So far, the project has received $5 million in part from the
county’s measure A sales tax to cover planning. Construction is
expected to be funded by local, state and federal grants, which the city
is currently working on obtaining. The project is a collaboration between
the city and the San Mateo County Transportation Authority.

San Mateo County. The Department proposes to construct a new overcrossing
extending from the Utah Avenue/South Airport Boulevard intersection to San
Mateo Avenue. The intersections at South Airport Boulevard/Utah Avenue and
San Mateo Avenue/Utah Avenue will be reconstructed to include turn lanes
and connect to the new overcrossing. The Airport Boulevard/Produce
Avenue/San Mateo Avenue intersection will be modified or reconstructed.
The project is currently programmed in the 2022 State Transportation
Improvement Program (STIP) for a total of $15,750,000, which includes
Plans, Specifications, and Estimates. Construction is estimated to begin
2024-25. The scope, as described for the preferred alternative, is

San Francisco HOT/HOV Lanes
In January 2017, it was reported that exploration has begun on creating HOV lanes between the San
Francisco City/County line (~ SF 0.0) and I-280 (~ SF R4.337L), and
possibly making those lanes HOT ("Express") lanes. The notion of charging
drivers to use an express lane met heat from supervisors, who earlier this
month voted against funding $4 million to study express lanes in the next
phase of the study. The supervisors voted 5-4 in favor of funding the
study, but with the absence of two supervisors were unable to garner the
necessary six-vote majority.
(Source: SF Examiner, 12/27/2018)
In July 2018, it was reported that transit officials
are looking into carving out carpool lanes along both US 101 and I-280
that could double as toll lanes to allow drivers willing to pay a bit
extra for a faster commute in and out of the city. The southbound commute
lane would extend along I-280 from King Street, near AT&T Park, down
to where US 101 meets I-380 near San Francisco International Airport. The
northbound lane would run along US 101 — from I-380 up to the San
Francisco County line — then pick up again on I-280 from Mariposa to
King streets. The San Francisco lanes could eventually hook up with other
express lanes being planned in San Mateo — and those that are
already in operation in Santa Clara County. In time, they could stretch
all the way to Morgan Hill. In some sections, the new lanes would take the
place of the highway’s existing shoulder. In other sections, adding
a carpool lane would mean taking out a lane of traffic. The estimated cost
would be $60 million to $100 million. An estimated 300,000 people a day
travel the heavily congested Peninsula corridor, including drivers and
passengers in single cars, passengers on Muni and SamTrans buses, and
techies on the fleets of private commuter shuttles that serve Silicon
Valley campuses. There are also an increasing number of ride-hailing
services such as Lyft and Uber, ferrying people to and from the airport.
It’s estimated the carpool lanes could shave five to nine minutes
off the trip. At the same time, losing regular lanes to express lanes
could add up to five minutes for people not in a carpool. As this is San
Francisco, there are questions: (1) Who benefits the most from the lanes?
Those who live in San Francisco, or those who live elsewhere and commute?
(2) Should the carpool lanes should be open for a minimum of two people in
a car — or three? (3) Whether drivers who are willing to pay should
be allowed onto the lanes, as they are in other parts of the Bay Area?
After all, this is San Francisco, and letting the affluent buy their way
out of traffic is not necessarily the ideal way to promote use of public
transit. The price paid depends on the time of day and length of the trip.

In March 2020, the CTC authorized reqlinquishment of right of way, consisting of collateral facilities, in the city and county of San Francisco (City) along US 101 at 3rd Street, just N of Meade Ave (04-SF-101-PM 0.7).
101 Deck Replacement project at Alemany Circle (~ SF 2.109)
In October 2019, warnings started to surface about an
upcoming "carmaggedon" in San Francisco in July 2020. This is when
Caltrans will replace 800-feet of bridge deck on US 101 just north of the
Alemany Boulevard exit in San Francisco. During the project the bridge
deck of the freeway will be demolished and rebuilt, which will require
detouring freeway traffic on and off the freeway to provide room for
construction. The project will begin in July 2020 and be finished within
three weeks. This portion of the US 101, sometimes referred to as the
Bayshore Freeway, was built in the early 1950s. Over the past 70 years,
weather and heavy traffic have deteriorated the bridge deck to the point
where replacement is the most feasible option. A bridge deck is a large,
concrete and steel box which sits on top girders spanning the space
between bridge columns. Workers build wooden forms to hold wet concrete,
which they lay atop steel girders. A steel lattice is built on top the
forms over which they pour concrete. The concrete hardens into a sturdy
bridge deck. The process used when this bridge was built is not very
different from the process used today. To provide room to build the
project, Caltrans will build a detour that will take northbound US 101
traffic off the freeway at the Alemany Boulevard exit. Traffic will travel
about 600 feet and re-enter the freeway at the Northbound US 101 on-ramp.
(Source: Caltrans Alemany Project Page)
In April 2020, it was reported that the traffic
reductions during the Spring 2020 Coronavirus Pandemic have permitted
Caltrans to move up the schedule for the US 1010 Alemany Project. The
project was expected to highly-impact San Francisco’s commute. The
project was originally scheduled for July, at a time when traffic is
lighter than normal anyways as people go on vacation, but traffic during
the "safer at home" orders is even lighters. "This area normally has about
240,000 vehicles that go over it every day," according to Caltrans.
"We’re seeing reductions in the region of about 40-60%, which makes
it a great time to do this." The project was originally designed to take
about 18 days, but Caltrans is expecting to improve the amount of time
that it takes to do the work. Work starts April 25, and they expect to be
done by early May.

In May 2020, it was reported that contractor C.C.
Myers, now doing business as Myers & Sons, was the prime contractor on
the just-completed $37 million rebuild of the Alemany Boulevard overpass
on US 101 in San Francisco. The rebuild was originally scheduled to begin
in July 2020, but was moved up to April to take advantage of the drop in
traffic brought on by the pandemic. Caltrans offered a bonus of $1 million
for every day Myers finished the job ahead of the original 18-day
schedule. The flip side of the deal was that Myers would have to pay back
$1 million for every day the job went beyond 18 days. Myers got the work
done in nine days. Their quick work scored an $8 million bonus (which was
the maximum bonus). This is common for the firm. After the 1994 Northridge
earthquake in Southern California, Myers fixed four damaged bridges on the
Santa Monica Freeway (I-10) in Los Angeles in 66 days, a full 74 days
ahead of schedule, and earned a $14.8 million bonus. When an overturned
gasoline tanker explosion destroyed a three-lane overpass section of the
MacArthur Maze (I-580/I-80 jct.) in Emeryville in 2007, the Myers firm got
a $5 million bonus for finishing ahead of schedule.

Central Freeway Removal (~ SF M5.447, SF R4.359R to SF T4.942)
Note: With the closure and removal of a portion of the Central Freeway in San Francisco between Fell Street to Turk in 1996 as part of the 1989 earthquake damage, Route 101 is now signed on Van Ness Ave. from the Central Freeway. In early 1997, the Central Freeway was reopened in the northbound direction, but is not presently signed as Route 101.
The portion of this route defined as "the approach to the Golden Gate Bridge" in the legislative definition depends on Section 72.1 of the State and Highways Code. This section (defined by Senate Bill 798, Chapter 559, 9/29/99) defines the Central Freeway Replacement Project. This involves demolition of the existing Central Freeway, construction of a new freeway between Mission Street and Market Street, construction of appropriate ramps to the new freeway, and an improvement of Octavia Street from Market Street north. According to Robert Cruckishank, as of Summer 2004, the new Central Freeway in San Francisco is taking shape, with piers constructed and steel beams being lowered into place for what will be the viaduct itself. The freeway will end at Market Street and what had been a freeway north of Market will become Octavia Boulevard, a "Parisian-style" landscaped road.
(By the way, Octavia Street is named after Miss Octavia Gough, the sister of Charles Gough, who was on the commission to lay out the streets west of Larkin Street known as the Western Addition. This comes from an obituary of Gough, published in the San Francisco Call, dated July 27, 1895. It eliminated the former supposition that Octavia meant the eighth street back from Divisadero. It documents the relationship of Charles Gough to Octavia Street and; almost surely, to Steiner Street, named for Gough's good friend. Steiner was delivering water in the pioneer days when Gough was delivering milk.)
According to reports, demolition of the existing
freeway west of Mission Street (the remains of the double-deck section
built in 1957-9) began in January, 2003 and continued for 180 days, with
penalties of $9600/day for each day it runs over (a closure
party—the end of the freeway revolt—was held in March 2003).
Construction of the new Octavia Blvd on the land previously occupied by
the freeway from Market Street to Fell Street east of Octavia Street began
in October, 2003 and was originally scheduled to be completed in
September, 2004. During demolition, Mission, Market, and Oak Streets under
the freeway will be closed on some weekends. Other streets are apparently
subject to longer closures. A new section of elevated freeway, with two
lanes in each direction (plus a right-turn lane at the very end) will be
built from Mission Street to Market Street, replacing the current
northbound-only structure. Construction began in February 2004 and is to
be completed in February, 2006. Because the new structure will meet Market
Street at grade, McCoppin Street between Market Street and Valencia Street
will be closed. Caltrans is not allowing anything to be built under the
freeway structure because they may need access to it from underneath, so
some of the space underneath may continue to be used for parking lots.
(Thanks to a posting by Eric Fisher on m.t.r for
this information.)
In early September 2005 (about a year late), the long-awaited replacement for San Francisco's Central Freeway was opened. Where the freeway structure was, drivers heading north or west descend from the freeway at Market Street and are greeted by a boulevard with poplar trees in the middle and Chinese elms on each side of the four-lane thoroughfare between faux historic lampposts. The central roadway with its lines of trees is framed by a one-way path on each side reserved for local traffic—the east side is for drivers heading north and west side is for those heading south. Even with parking lanes and a sidewalk, the result is a passage that measures just 133 feet from side to side. There are a number of awkard features to the design, but most reports seem to feel it is an improvement.
Routing in San Francisco
There's lots of confusion about the current routing of US 101, because of problems with signage in the city of San Francisco. After the 1989 Loma Prieta earthquake, US 101 N was rerouted to exit the Central Skyway at Mission St., then NE to Van Ness Ave. US 101 S was rerouted along Van Ness Ave and South Van Ness Ave to the Central Skyway on-ramp. However, there are signs labeled "To US 101" on Central Freeway N at 7th Street, making people believe that US 101 exits there. Similarly, the "To US 101" signs southbound make people think US 101 exits at 5th Street. This is wrong. According to Caltrans, US 101 officially is routed on the Central Freeway. It is neither 7th or 5th St. Hence, to follow US 101, take the Central Freeway. Note that the signs at 5th St. and 7th St. were specifically requested by the City of San Francisco; subsequent surface street signing to direct people to US 101 is the city's responsibility. The city has placed such signs; according to a missing piece of the Photolog uncovered by Joe Rouse, the path is 7th to McAllister to Leavenworth to Turk to Van Ness, with the route to US 101 being signed at each junction (in addition to several reassurance trailblazers on 7th Street).
According to Joe Rouse, the Central Freeway is officially still part of US 101, even after the post-Loma Prieta modifications. Prior to the quake, the Central Freeway ended at Golden Gate and Turk; Turk and Golden Gate were part of US 101 between the Central Freeway and Van Ness Avenue. After the Central Freeway was lopped off at Fell Street, Golden Gate and Turk were decommissioned as state highways and a break in the official routing was created on US 101 at Fell Street, with the route resuming at Van Ness and Golden Gate. Van Ness Avenue south of Golden Gate Avenue (and Mission Street for that matter) have never been officially adopted as state highway.
After the Central Freeway was lopped off at Fell Street, signage for US 101 was extended on Van Ness south of Golden Gate and on Mission Street, but this is signage only—not route adoption. While the Central Freeway's future was being debated, the City of San Francisco requested that Caltrans direct traffic bound for NB 101 so that those coming from the Bay Bridge were directed to exit at 5th Street (and then continue down Harrison to 7th), and NB 101 traffic was directed to continue to 7th Street via I-80. From there, to get to US 101 motorists were directed to use 7th to McAllister to Leavenworth to Turk to Van Ness. But this is signage only—these streets were never adopted as part of US 101. The purpose was to get motorists to bypass the confusing mess at the Market/Van Ness/Mission intersections. The state did leave a sign for 101 North at the turnoff to the Central Freeway from WB I-80, again most likely for motorists's benefit, since there are two onramps to WB I-80 downstream of the 5th Street exit. It was also useful if you were coming from the Bay Bridge and you somehow missed the exit to 5th Street, as you could still get to US 101 North via the Central Freeway.
Although the signage for the Central Freeway from the south indicated that it was for Mission and Fell Streets, signage for US 101 North was also left on that connector to the Central Freeway (where the offramp for 9th Street splits off). Once on the Central Freeway itself, 101 North traffic was directed to exit at Mission. So if you were coming from the south and didn't see the signs directing you to 7th Street, you were okay too.
With the completion of Octavia Blvd, it appears that traffic from the south and from the east are once again directed to use the Central Freeway to continue on NB US 101, rather than use the 7th or 5th Street exits. The exit number listing for WB I-80 will have to be corrected to show that Exit 1B is now for US-101 North. It currently does not show this. So what is the planned alignment for US 101 in this area? It appears that the plan was to continue to sign the Mission Street exit as the exit to continue north on US 101, with the mainline touchdown to Octavia Street being treated as an exit. This makes it look like US 101 is exiting itself. But nothing is finalized. Although the signage may show route continuity via Mission and Van Ness, officially, there is a gap in Route 101 from where the freeway ended at Fell Street to the intersection of Van Ness and Golden Gate Avenues. The southern end of this gap might be moved to the new end of the freeway at Market Street.
In January 2017, the CTC authorized relinquishment of right of way in the city and county of San Francisco along Route 101 (Van Ness Avenue) between Plum Street and Lombard Street (04-SF-101 PM T4.6/6.7), consisting of nonmotorized transportation facilities, namely sidewalks. The City and County, by relinquishment agreement dated December 16, 2016, agreed to waive the 90-day notice requirement and accept title upon relinquishment by the State.
In December 2000, the CTC had on its agenda adoption of a traversable highway a segment of Route 101 in San Francisco from PM SF R5.0 (PK SF R8.0) at Erie Street to PM 5.3 (PK 8.5) at Golden Gave Avenue.
There appear to be some plans to make a portion of this route in San Francisco into an underground tollway. The San Francisco Chronicle published an article on 2/18/2001 where it indicated that transportation planners "said the city should look into building ``supercorridor'' roads under Van Ness Avenue, 19th Avenue, and Fell and Oak streets." The suggested 19th Avenue tunnel would run five miles, from Junipero Serra Boulevard through Golden Gate Park and up to Lake Street, with exits at Brotherhood Way, Ocean Avenue, Quintara Street, Lincoln Way and Geary Boulevard. The Van Ness tunnel would run almost two miles, from about Fell to Lombard Street, with exits at Broadway and Geary Boulevard. Along Oak and Fell, the planners suggest an underground road running more than half a mile from Laguna to Divisadero streets. However, the roads would would violate the long-standing general plan for San Francisco, which calls for no new highway capacity.
Lombard Street Improvements (~ SF 6.701 to SF 7.798)
In March 2016, it was reported that the San Francisco
Municipal Transportation Agency’s Board of Directors was considering
a $12 million safety overhaul for the street. In this overhaul, Lombard
Street could be redesigned to feature numerous curb extensions called
“bulbouts,” which help pedestrians become more visible behind
parked cars, and also reduces the distance from curb to curb when crossing
the street. SFMTA would also paint “zebra” style
high-visibility crosswalks all across Lombard, which the agency says
reduces crashes with pedestrians by 37%. Leading Pedestrian Intervals,
which let walkers cross briefly before cars allowed to move, would also be
installed. Advanced limit lines would also be painted at intersections.
These are lines restricting cars to stopping ten feet before crosswalks.
These changes won’t take place on Lombard’s famous crooked
portion – rather, they will happen between Francisco and Franklin
streets, leading to the entrance of Golden Gate Bridge near the Presidio.
This portion of Lombard is a leg of US 101, under the purview of Caltrans.
Caltrans plans to repave Lombard in 2018, giving SFMTA a chance to revamp
the street for safety. City officials identified Lombard as one of its
most dangerous streets in a study for its Vision Zero policy, in which The
City pledged to end all traffic deaths by 2024. On Lombard between 2008
and 2013, there were over 150 collisions resulting in injuries, two of
which were fatal and 20 severe, according to the SFMTA.

There have been some small relinquishments, either of current routings or past routings. CTC June 2000 Agenda Item 2.3c included relinquishment resolutions for San Francisco PM G4.7-5.3 in San Francisco.
In April 2021, it was reported that the San Francisco Municipal
Transportation Agency’s Board of Directors approved adding temporary
HOV lines to segments of Route 1 and US 101 cutting through the Richmond
District and Cow Hollow. The temporary lanes are the latest in a nearly
yearlong effort by the city’s largest transit agency to increase
reliability as the pandemic reduced public transit services and turned
more San Franciscans to getting around by car. The plan reserves the lanes
closest to the curb for high-occupancy vehicles on stretches of these
three-lane corridors. The HOV lanes would be implemented on Route 1 from
the beginning of Crossover Drive and Lincoln Way through Golden Gate Park
and on Park Presidio Boulevard past Lake Street. The remaining lanes would
be unaffected. For US 101, a temporary HOV lane would be installed on
Lombard Street and Richardson Avenue, running from Lyon Street to Van Ness
Avenue.

Doyle Drive/Presidio Parkway (~ SF 7.798 to SF 9.472).
There are also plans to reconstruct the Doyle Drive
portion from Lombard St/Richardson Ave to the Route 1 Interchange in San
Francisco. Existing Doyle Drive was built in 1937 and is substantially
unchanged from then. Elevated sections consist of complex steel truss
girders on foundations of doubtful strength. It is located in a
'liquefaction zone' making it especially liable to earthquake damage. The
road was built with 2×3 10ft (3m) travel lanes, no median, and no
real shoulders.
The permitted design of the Parkway has 3 lanes
northbound to the bridge and 4 lanes southbound off the bridge, the extra
lane so there can be a clean 2+ 2 lane split leading away from the bridge
into a pair of surface arterials Marina Blvd and US 101 (Richardson,
Lombard). They will be modern 3.6m (12ft) wide lanes and there will be
shoulders both sides and a grassed median. Close to half the length will
be underground (in two pairs of cut and cover tunnels of 260m and 310m) or
elevated. At each end the Parkway will transition to signalized arterial
standard roadways, not expressway.

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $8,000,000 for High Priority Project #2606: Replace South Access to the Golden Gate Bridge-Doyle Drive. The act also authorized $6,000,000 for High Priority Project #3808: Replace South Access to the Golden Gate Bridge—Doyle Drive.
The environmental studies for this project are part of TCRP Project #22, requested by the San Francisco County Transportation Authority. More information can be found at http://www.doyledrive.org/. It appears that there may be an extra toll on the Golden Gate Bridge to help pay for repair of the dangerous Doyle Drive approach, which handles 91,000 vehicles a day. The toll, which has not yet been set, probably would fluctuate, rising during times of heavy traffic to a high of around $2. Doyle Drive is particularly dangerous because lanes are too narrow by 2 to 3 feet, there's no barrier separating opposing traffic, there are no shoulders and the structure is seismically fragile. According to San Francisco transit officials, Doyle Drive has almost three times the typical number of accidents for a facility of its type. Toll revenues would be used to help pay for the $810 million project to replace the 70-year-old Doyle Drive with a wider, safer, sturdier roadway. The federal government would pay an additional $35 million. San Francisco officials have collected the bulk of the money from state and local sources and hope to begin construction by 2009. Construction cost (not project cost) of the 2.6km (1.6 miles) of seven lane (4 lanes SB, 3 lanes NB) expressway is estimated at $1,045m or $387m/km, ($653m/mile), and $57m/lane-km ($93m/lane mile.)
In 2007, the CTC considered a number of requests for funding from the Corridor Mobility Improvement Account (CMIA). One request were funded: construction of aux lanes from Embarcadero to Marsh Rd in San Mateo County ($60M). The Doyle Drive replacement in San Francisco County was not recommended for funding. However, in August 2007 the CTC amended the project (TCRP #22), which is an environmental study for reconstruction of Doyle Drive, from Lombard St./Richardson Avenue to Route 1 Interchange in City and County of San Francisco to update the project schedule and funding plan. TCRP Project #22 is to replace Doyle Drive (US 101) in order to improve the seismic, structural, and traffic safety of the roadway. The redesign of Doyle Drive will have qualities that keep within the setting of the Presidio of San Francisco as a National Park, will incorporate increased intermodal access to the Presidio, and will improve access from local roadways. The project has attracted intense scrutiny from the National Park Service, the Presidio Trust, and the public, as it affects an area of the Presidio where the Presidio Trust is planning the restoration of a river habitat along Tennessee Hollow, as well as the planned expansion of Crissy Marsh. The project is now scheduled to start Phase 1 in FY07/08, with completion estimated for FY12/13. Note that this is just for the environmental study!
Part of the problem with the Doyle Drive reconstruction
is a provision included in the $58 million federal offer: the new Doyle
Drive must become a toll road that would help pay back the construction
costs. This has resulted in a lot of opposition from the North Bay that
would pour south - particularly from Marin County. This opposition may
endanger the effort to replace the road, threatening to entangle it in the
same kind of political morass that stalled construction of the new eastern
span of the Bay Bridge and caused its cost to soar. Marin officials have
called the proposal to charge a $1 to $2 toll on the road unfair to North
Bay commuters, who account for 75 percent of the morning southbound
traffic on Doyle Drive, and labeled the proposal "a Marin commuter tax."
Regional transportation officials, on the other hand, believe the federal
money may be the only chance to fix the dangerous structure. The issue
needed to be resolved quickly: to qualify for the federal money, San
Francisco needs the legal authority to charge tolls on Doyle Drive by
March 31, 2008. San Francisco needed the state Legislature to pass a law
allowing the city to collect tolls, yet the political dispute seems to
have cowed Bay Area legislators who planned to introduce that legislation.
Election year politics are part of the argument; the other part is that
since Doyle Drive is a state highway, Caltrans should pay to replace the
narrow, seismically fragile viaduct. But Caltrans didn't build the road
originally: The Golden Gate Bridge district built the road with no
shoulders, no median and narrow lanes in 1933 as part of the bridge
project. In 1945, it was turned over to the state Division of Highways,
predecessor to Caltrans, according to a history compiled by the San
Francisco County Transportation Authority. But the bridge district didn't
give up its interest in Doyle Drive. In 1955, it asked the state to
rebuild Doyle Drive and make it wider. When the state came up with a plan
for an eight-lane highway with a median, San Franciscans objected, and the
state Legislature passed a bill requiring San Francisco's approval to
widen the highway. Numerous attempts to come up with a plan - and money -
to replace Doyle Drive without adding more lanes of traffic have fallen
victim to community opposition and a lack of funding. The current plan,
with an estimated cost of $1.1 billion, is the result of about 15 years of
planning, studies and negotiations. The so-called "Presidio Parkway"
design was selected in 2006 after planners, engineers and community groups
winnowed down 16 options to one that features a combination of a high
viaduct, two short tunnels, and an open sunken roadway, all with a
landscaped median. The existing Doyle Drive, which carries 120,000
vehicles a day, is near the top of the state's list for bridges in need of
replacement. Its six lanes are narrow, its road has no shoulders and
opposing lanes of traffic are separated only by a line of plastic stakes.
According to Caltrans, Doyle Drive is rated a 2 out of 100 on the Federal
Highway Administration's structural safety index. The current funding plan
for replacement, according to the Metropolitan Transportation Commission
and the San Francisco County Transportation Authority, has the state
contributing about $475 million from a variety of accounts, San Francisco
chipping in $68 million from sales tax revenues, and the federal
government adding $58 million from the Urban Partnership program. That
federal program requires congestion tolling - tolls that rise and fall
with congestion in an effort to dissuade drivers from traveling when
traffic is heaviest. There's still a gap of about $460 million.
(Source: San Francisco Chronicle, February 19, 2008)
In May 2008, the Golden Gate district considered a
congestion toll plan. The district already plans to increase by a dollar
its current toll of $5 for those who pay with cash and $4 for those who
use FasTrak. The congestion-based toll would add a dollar more during the
periods of 7 to 9 a.m. and 4 to 6 p.m. on weekdays and 3 to 7 p.m. on
weekends and holidays. This would be part of a federal program that would
bring $158 million in federal funds to the Bay Area for transportation
projects, including Doyle Drive. North Bay drivers and politicians -
particularly those from Marin County - objected to the Doyle Drive toll
idea, and bridge directors from the north side of the span pledged to
fight what they called "a Marin commuter tax." As part of a regional
compromise, the bridge board agreed to collect a congestion-based toll on
the bridge but only if it could use the revenue to fund improvements to
Golden Gate buses and ferries. The board also voted to ban use of any of
the money to pay for Doyle Drive improvements.

In Mid-December 2008, the San Francisco Board of
Supervisors, acting as the San Francisco Transportation Authority board,
certified the environmental impact report for the Doyle Drive replacement
project and officially selected the $1 billion Presidio Parkway design for
construction. This clears the way for the federal government to approve
the project, which is expected by the end of 2008. The authority hopes to
complete engineering and design, and begin construction, by 2010. The new
Doyle Drive is expected to open in 2014. The design chosen includes
stretches of elevated and at-grade roadway and two tunnels, with six lanes
of traffic, three in each direction, shoulders, and a median. The parkway
design was favored by community committees in 2006. Some relatively minor
changes have been made the past two years to satisfy officials at the
Presidio National Park and neighbors concerned about pedestrian safety.

In March 2009, it was reported that Doyle Drive was among 57 transportation projects in California chosen to receive the first wave of 2009 federal stimulus funds. The Doyle Drive replacement is expected to create about 500 jobs. The commission plans to disburse the money in April 2009 for the 1.2-mile Doyle Drive project, pending a commission environmental approval. The rebuilding of Doyle Drive will cost about $1 billion. Before the commission's decision Wednesday, sources for all but about $100 million of the funding had been identified. Both U.S. Sen. Dianne Feinstein and House Speaker Nancy Pelosi, Democrats from San Francisco, have said that securing full funding to replace Doyle Drive is a top priority. They're looking to the economic stimulus windfall from Washington to cover the remaining tab. If the money comes through, construction could begin by the end summer 2009, instead of in 2010, with completion anticipated in 2014, state and regional transportation officials said. The roadway is used by more than 100,000 vehicles a day.
In April 2009, the CTC accepted the EIR on the Doyle Drive project. The purpose of the project is to improve the seismic, structural, and traffic safety of the roadway that is approaching the end of its useful life. Doyle Drive, the southern approach of US 101 to the Golden Gate Bridge, is 1.5 miles long with six traffic lanes. The proposed project will replace the existing facility with a new six lane facility and southbound auxiliary lane, between the Park Presidio Interchange and the new Presidio access at Girard Road. In April the CTC also allocated $50,000,000 in funding from the Federal American Recovery and Reinvestment Act of 2009 (ARRA).
In January 2010, construction started with the closure of a sharp hook-shaped curve that veered off of Doyle Drive before the toll plaza and passeed beneath the highway to Park Presidio. The southbound Doyle Drive off-ramp to southbound Route 1 will be periodically closed, and starting in February 2010, the northbound Route 1 to southbound Doyle Drive connection will be closed for a year and a half for construction. The official detour uses Lombard Street, Van Ness Avenue and Geary Boulevard. Drivers approaching Doyle Drive will be warned of the closures with electronic signs. Those missing the warnings will be able to use a "last chance" detour at Lincoln Boulevard or Merchant Road via the visitors parking area at the south end of the bridge.
In February 2010, the CTC approved amending Traffic Congestion Relief Program (TCRP) Project 22 and re-allocate previously allocated funds for the Route 101; environmental study for reconstruction of Doyle Drive, from Lombard Street/Richardson Avenue to Route 1 Interchange in the city and county of San Francisco. Specifically, this reprogrammed $1,300,000 TCRP from Plans, Specifications & Estimate (PS&E) to Construction Support, and reallocated previously allocated funds from PS&E to Construction Support. This change related to an Emergency Limited Bid (ELB) contract that is being used to relocate some of the utilities. Although the use of such approach will help advance the delivery of that contract by about 20 months, the Federal Highway Administration does not recognize the ELB as an approved method of delivery, prohibiting federal funds use on this contract (and the original plan was to use Federal demonstration funding). Note that most of the Doyle Drive/Presedio Parkway project is being done through a public-private partnership (called P3 funding); in particular, P3 is being used for Phase II construction.
Work began on the first tunnel in July 2010. The $116 million Battery Tunnel, funded by federal stimulus dollars and $33 million in local funds, is under construction in the Presidio along with an elevated 1,340-foot long viaduct just south of Doyle Drive that would take drivers into city. When the 1,036-foot long tunnel initially opens around Labor Day 2011, the five lanes inside will handle both northbound and southbound traffic until a second northbound tunnel is built where the existing Doyle Drive now stands. Traffic in the tunnel will be separated by a moveable Renderings show the two Battery Tunnels, with the southbound tunnel at right.
In February 2012, it was reported there there may be
some funding kerfluffles for the Doyle Drive project. Specifically, the
San Francisco County Transportation Authority needs to come up with $60
million so that Golden Link Partners, a private consortium that has
entered into an unusual public-private partnership, can begin construction
of the second phase of the project. The authority needs to have firm
funding sources within months so that the consortium can secure private
financing by the end of June and proceed with the second half of the work.
The shortfall was caused by two problems. First, $34 million in state
transportation funds that have been pledged to the project will note
arrive quickly enough. The Metropolitan Transportation Commission, the Bay
Area's transportation planning and financing agency, has proposed
advancing the money to San Francisco and getting paid back over the next
several years. But the California Transportation Commission, which has had
objections to the public-private approach on Doyle Drive, must approve
that proposal. Secondly, there is a $26 million gap that resulted when the
idea of redirecting federal money earmarked for two other Bay Area
transportation projects didn't get congressional support. Construction
crews have been building the first part of the 1.6-mile Presidio Parkway -
the new name for the connection to the Golden Gate Bridge - since the end
of 2009. The work includes a new US 101/Route 1 interchange, a southbound
high viaduct and the southbound Battery Tunnel. By Spring 2012, the first
phase will be completed, and a temporary bypass paved. Traffic will be
moved off the old Doyle Drive and will share the newly built structures
until the rest of the Presidio Parkway is completed in early 2015.
Demolition crews will tear down the old concrete viaducts and roadways.
The existing narrow approach to the Golden Gate Bridge was built in 1937
as part of the bridge project. It's now considered unsafe because it lacks
a median and shoulders, is seismically fragile and sits atop unstable
soils.

In May 2013, it was reported that work has started to
remove the remainder of Doyle Drive. The roadbed, steel trusses, columns
and finally the foundation of the structure will be peeled away. Work on
the new viaduct, which will take drivers north into Marin, is expected to
begin in summer 2013. Three tunnels, a low viaduct and a new interchange
to the Marina and the Presidio will be part of the second phase of work as
well. The new design will open up views of San Francisco Bay, create new
direct access to the Presidio from the new parkway and improve pedestrian
and cyclist connections within the Presidio. The major portion of
construction is scheduled to be complete by late 2015 with landscaping
work to follow through mid-2016.

In August 2014, the CTC authorized reprogramming of funds from the design phase to construction capital. The funds are being used for wetlands mitigation in the area that surrounds the batch plant, located near the entrance to the northbound Battery Tunnel.
In May 2015, it was reported that all of the roadways
connecting Park Presidio-19th Avenue to the Marina, and the
Marina to the Golden Gate Bridge were anticipated to open in June 2015.
Reconstruction of Doyle Drive occurred in two phases starting in 2008. The
new road is now also known as the Presidio Parkway. The new tunnels,
dubbed the Main Post and Battery tunnels, have been alternatingly open to
traffic during construction. Some construction will continue through 2016.
The green tunnels will be the icing on the cake. Though bare now, by
project’s end, they will be covered in grass, trees, benches, and
trails open to the public.

In July 2015, it was reported that over the July 4
weekend, the original Doyle Drive was closed and replaced with the
brand-new Presidio Parkway, a sleeker, safer, better-looking version of
Doyle Drive. Motorists heading toward the bridge from San Francisco will
transition to Presidio Parkway as they do now, but then almost immediately
they will cross a small bridge over what will become an extension of the
Crissy Field Marsh — it will feel a bit like a bump. Drivers will
then speed into the first of two new tunnels, emerge where the temporary
bypass once was and make a straight shot uphill, to the second tunnel.
Nothing like twisting through the narrow lanes of the old road that often
felt dangerously like bumper cars. When they come out of the second
tunnel, they’ll be on the new, high viaduct that soars above the
Presidio on the way to the Golden Gate Bridge toll plaza and the bridge
itself. If they decide they don't want to cross, they can use the
“hook ramp” that veers off to the right, then curves beneath
US 101 and disgorges vehicles onto SB Route 1. Also reopening is the NB
Route 1 to SB US 101 ramp. Both have been closed since 2010. Drivers
heading into San Francisco from the Golden Gate Bridge will head through
the toll plaza, south past Route 1 and into the tunnel that was share with
NB traffic on the temporary alignment. Instead of following the temporary
alignment, which weaves toward Crissy Field in a gentle S-curve, a new
roadway will carry them straight to a second tunnel at the Main Post. When
they emerge, they’ll have the choice of staying on the main road to
Richardson Avenue or taking a new off-ramp on the right side that will
give drivers a choice of heading toward the Marina District or into the
Presidio.

In April/May 2016, the Atlantic had a long discussion
about how the Presidio Parkway project stiched the two halfs of the
Presedio back together. The Doyle Drive replacement, completed in 2015, is
tucked inside concrete tunnels, the roofs of which will serve as green
bridges linking the two sections of the Presidio that were separated in
the 1930s. (An existing surface street, Old Mason Street, still runs
parallel to the shoreline, but is easily traversable by pedestrians and
bicyclists.) The top of the now-covered road and the surrounding area will
be landscaped by James Corner Field Operations, the landscape-architecture
and urban-design firm behind New York City’s High Line. In the end,
the Presidio will gain 14 acres of newly developed park space.
Corner’s design features a terraced landscape that climbs from
marshlands along the shore up to gently crowned tunnel tops, where a
series of lawns, meadows, and sweeping pathways are interspersed with
small gardens and nooks that block the breezes off the water. The new
ground over the tunnels will be about 30 feet higher than most of its
surroundings, offering heretofore unavailable views. The plantings
selected by Corner aim to call back to the natural conditions that existed
on the site before the road cut through. More than 50 native species of
plants collected throughout the Presidio are now being cultivated in its
nursery for the park’s landscaping, which is expected to start next
year and be completed in late 2018. Various grasses and succulents will
blanket the tunnels, and the bluff leading down toward the water will be
covered in native shrubs and grasses like those seen atop other
escarpments along the edge of the bay. The hope is that these groups of
plants will create habitats for the diverse bird, butterfly, and insect
populations of the Presidio, as well as a natural refuge for the
city’s residents and visitors.
(Source: Atlantic Monthly, May 2016)
In April 2019, it was reported that the Presidio
Parkway is more than two years late and $208 million over budget. When the
commission approved another $34 million in delay-related spending in March
2019, two commissioners who originally opposed the project lamented their
predictions had come true. “This has been a fiasco from the
beginning,” Commissioner Bob Alvarado said at the March 14 meeting.
Before Schwarzenegger got involved, the project had an estimated cost of
$473 million to $499 million. It would replace a 1.6-mile section of US 101 south of the Golden Gate Bridge that had deteriorated since it was
built in 1936 and no longer met earthquake standards. Schwarzenegger
wanted to try something different, calling for a public-private
partnership. Unlike other state highway projects, which Caltrans would
design, put out for bid and then pay a contractor to build, the
partnership approach would select a contractor at a lower upfront cost to
design, build and maintain the project for more than 30 years. Proponents
of Schwarzenegger’s approach, including Caltrans leaders, said it
would give the project a better chance of being completed on time and on
budget than the state’s traditional approach while shifting risks of
delays and future problems to a contractor. Caltrans selected San
Francisco-based contractor Golden Link Concessionaire to do the project
for $1.1 billion, and then asked the Transportation Commission and the
Legislature to approve the agreement. The commission’s staff, the
Legislative Analyst’s Office and Professional Engineers in
California Government all warned that the details of the contract
didn’t match the rhetoric surrounding the project, while warning of
its risks. Both bodies approved the project anyway, authorizing the state
to pay the contractor about $173 million once construction was done and
then $35 million to $40 million per year for 33 years. The project became
the first public-private partnership following 2009 legislation that
authorized the partnerships. The best fits for the partnerships, analysts
said, were projects that included upfront contributions from contractors
and continuous revenue streams, such as tolls. The Presidio Parkway is
near the Golden Gate Bridge toll, but the parkway is not funded by ongoing
fees. The state is paying for the Parkway through 2043 from its general
highway account. Commissioners approved seven supplemental fund requests
for the project from 2013 through 2018. They made an eighth at the March
meeting, bringing total over-budget spending to $208 million, after being
told that each of the two prior allocations would settle all outstanding
claims and disputes. The project was supposed to be finished in December
2016. Commission staffers and Caltrans said the Presidio Trust, the
national park that owns the land, required 46 additional permits since
then, which each took an average of five months to obtain.

Golden Gate Bridge (SF 9.899 to MRN L0.261)
Note that the Golden Gate Bridge is not part of US 101. The Golden Gate is maintained by the
Golden Gate Bridge, Highway, and Transportation District. However, the Golden Gate Bridge is part of a Safety Enforcement-Double Fine Zone, per Senate Bill 155, Chapter 169,
on July 23, 1999 and a Safety Awareness Zone per SB 988, Chapter 593,
September 29, 2006. The Golden Gate Bridge will also be undergoing a
seismic retrofit under TCRP Project #143. The Golden Gate Bridge opened in
1937.
In January 2010, it was reported that the Golden Gate Bridge District was working on plans to raise money for the bridge. Ideas include elevator rides to the very top of the Golden Gate Bridge's international orange towers, or a chance to tour the famed structure's catwalks beneath the busy roadway. Some of the ideas are in this article from the LA Times.
In March 2011, it was reported that the main cables of the Golden Gate Bridge would be renovated for the first time since the span opened in 1937. This isn't a replacement (the cables cannot be replaced); it involves chipping the old paint off, vacuuming the chips and repainting the cables. Exterior paint is what protects the 80,000 miles of wire inside the cables from corroding.
In November 2016, it was reported that maintenance of the Golden Gate
Bridge was lacking. While the main portion of the bridge is regularly
repainted, the Golden Gate Bridge’s main cable has not been painted
in its entirety since the mid-1930s, only spot painted. When viewed from
the air by helicopter or from the ground, virtually the entire length of
the cable housing appears to show wear and tear. Golden Gate Bridge
Manager Denis Mulligan explained that the Bridge District has different
time frames to do work on different components of the bridge, and says
that the District has based those time frames on what kinds of repairs and
upkeep might be needed. While the outside cable casing may look bad, the
27,000 individual steel strands inside the cable casing have remained
pristine. Back in 1969, the District hired an outside consultant
engineering firm to walk the bridge. The firm issued a report that
recommended the main cable be painted in its entirety as soon as possible.
Despite the recommendation, it never happened. The District started the
project about five years ago, but then stopped the painting. Engineers
announced that the hand rails along the main cable needed to be replaced,
for the safety of the bridge painting crews. Even Golden Gate Bridge Board
of Directors member Dietrich Stroeh has had some concerns about the cable,
and the south tower. Stroeh has talked to staff about getting the project
going again. But Stroeh said that another section of the bridge needed to
be treated for rust. “We found in exposing some of the sub
structures that the bracing underneath which is like crisscrossed, behind
the riveted piece on there,” explained Stroeh. “It was all
rusty.” Then there’s the money for the painting of the cable
in its entirety. The Bridge District had set aside tens of millions of
dollars to paint the bridge back in 2011. But Stroeh said it was spent on
other projects.

Information on how to pay the tolls on the Golden Gate Bridge in advance may be found here. This is especially significant if you are in a rental car, for there can be significant surcharges. Those who do not use the bridge frequently can use a one-time payment plan that allows them to use a credit card online or by phone or pay cash in person. Note that drivers do not have the option of paying cash on a Golden Gate Bridge crossing.
Golden Gate Suicide Barrier
In July 2010, a Metropolitan Transportation Commission committee approved $5 million in funding for the design of a suicide barrier on the Golden Gate Bridge. The barrier will cost $45 million and the bridge district said it will not spend money on the project - meaning federal, state or private funding must be found. If it is, the system would take about 18 months to install. The barrier plan calls for a net extending 20 feet below and 20 feet from the side of the span. The net would be made from stainless steel cable and would collapse slightly if someone jumped in, making it difficult to get out, bridge officials said. The district would buy a "snooper" truck with an elongated arm to get people out, although such rescues might be rare because the net is expected to act as a deterrent. Roughly two dozen people jump from the span each year, and more than 1,300 people have jumped from the span since it opened in 1937.
In October 2015, it was reported that Golden Gate
Bridge officials began the process of finding a construction firm to build
the landmark $76 million suicide barrier. This only occurred because the
bridge board approved a deal with the National Park Service to allow
builders to store material and equipment on park lands during
construction. This is because the Bridge District does not own any land;
when the span was built it received a permit from what was then known as
the U.S. Department of War. The park service is now the federal agency
that controls the land. Bids for the barrier work will be opened in
January 2016, with another six weeks needed to go through the submissions
made by bidders. Once a construction firm is selected, which could be as
soon as March 2016, preliminary work could start within weeks, although
parts for the actual net device would take some time to manufacture. Once
work begins, the project would take roughly 3.5 years to complete,
although financial incentives will be offered to the contractor to
complete the work as soon as possible. The bridge district’s barrier
plan calls for a net extending 20 feet below and 20 feet from both sides
of the span, although it will have to be modified in certain areas because
of surrounding terrain. The net would be made of stainless steel cable and
would collapse slightly if someone jumped in, making it difficult to get
out. While people could still jump into the net, such occurrences might be
rare because the net would act as a deterrent. Caltrans will contribute
$22 million to the overall project, the state $7 million from Mental
Health Services Act funds and the Golden Gate Bridge district $20 million
in addition to $27 million from the Metropolitan Transportation
Commission.

In April 2016, it was reported that work on the suicide
barrier for the Golden Gate Bridge will be delayed yet again. In February
2016, bridge officials reported there would be a two-month delay, in part
because the original steel selected for the project could not be
manufactured in large enough quantities in the United States. Rather than
have it made overseas, a different type of steel will have to be used for
the project. Because of the steel, other revisions and the volume of
questions, the bid opening date had been moved from March 8 to May 3,
2016. But potential bidders continue to have multiple questions on the
project that can’t be easily answered. Now the bid opening has been
pushed to July 12, 2016. Even with the delay the barrier work will be
completed by 2020 as initially anticipated and there will be incentives
for contractors to finish work sooner than later. The steel net and its
supports will be manufactured off site. The contractor will install the
net first along the east side of the bridge and then the west side. The
suicide deterrent project will be the first large-scale horizontal net
installation on a major bridge in the United States. At 385,000 square
feet, it will be almost the size of seven football fields, suspended 220
feet above the water. The bridge district’s barrier plan calls for a
net extending 20 feet below and 20 feet from the side of the span,
although it will have to be modified in certain areas because of
surrounding terrain. The net will be made of stainless steel, marine-grade
cable to stand up to the elements, bridge officials said. The net will be
gray instead of red to better blend with the water. Caltrans will
contribute $22 million to the overall project, the state $7 million from
Mental Health Services Act funds and the Golden Gate Bridge district $20
million in addition to $27 million from the Metropolitan Transportation
Commission.

In July 2016, it was reported that a potential major
stumbling block has developed for the Golden Gate Bridge suicide barrier
project: the low bid for the work has come in almost double the
construction cost estimate. The bridge district opened two bids for the
work, and the low bid came in at $142 million from the Oakland-based
Shimmick/Danny's Joint Venture. The Pennsylvania-based American Bridge Co.
submitted its bid at $174 million. The bridge has a $76 million financing
plan in place approved by the board that was based on consultant
estimates. The bridge district's barrier plan calls for a net extending 20
feet below and 20 feet from the side of the span, although it will have to
be modified in certain areas because of surrounding terrain. The net will
be made of stainless steel, marine-grade cable to stand up to the
elements. The net will be gray instead of red to better blend with the
water.
(Source: East Bay Times, 7/15/2016)
In September 2016, it was reported that the cost of the
barrier could escalate to as much as $198 million. The Golden Gate Bridge
Board voted in late September 2016 to formally delay the project until
Jan. 9 so a funding plan can be revised. Bridge officials were stunned in
July when bids came in almost double the $76 million estimate. Now span
officials are noting the project could be as much as $198 million, but
caution that that figure is likely high. It was included as a safeguard in
a budget planning document to acknowledge the high-end cost of the
project.

In November 2016, it was reported that Golden Gate
Bridge officials are close to finalizing a new funding plan to build a
suicide barrier on the span, a project that now has a price tag of $204
million. By December 16, the Golden Gate Bridge district board is expected
to vote on another $40 million for the project. Additionally, a committee
of the Metropolitan Transportation Commission will consider shifting $40
million in federal funds to the barrier project. The agency has already
provided $27 million. Additionally, Caltrans is expected to provide $40
million, with approval coming in early December. Caltrans has already
contributed $22 million. This brings the total additional funding to $120
million for the project. A $39 million construction contingency is worked
into the new $204 million cost and any unspent dollars would be shared
proportionately among the MTC, Caltrans and the bridge district. Officials
were hoping that if work could start this year, the project could be
finished by 2020.

In December 2016, it was reported that the Golden Gate
Bridge district board’s Building and Operating Committee voted to
recommend the work go to Oakland-based Shimmick/Danny’s Joint
Venture, which bid $142 million for the barrier work in July. It was the
lower of two bids. The original budget for the work was $84 million, which
included contingency work. Pending approval, the project is estimated to
begin in 2017 and be completed in 2021. The approval of Shimmick was a
close call. A rival contractor, Coraopolis, Pa.-based American Bridge
Company, filed a protest alleging Shimmick’s proposal failed to meet
many standards of the project, though Shimmick denied those allegations.
If the committee found the allegations had merit, both contracts would
have been rejected, because the Golden Gate District deemed the bridge
company’s $174 million proposal too expensive and the bid process
would have reset, possibly delaying the project by at least a year.

In January 2017, it was reported that construction on
the Golden Gate Bridge’s long-delayed suicide prevention net is
expected to take four years and could disrupt traffic at times. A
committee of the Golden Gate Bridge Highway and Transportation District,
the iconic structure’s governing body, recommended an allocation of
$2 million to the California Highway Patrol to facilitate traffic flow
while workers install the net. This funding would pay the CHP for opening
and closing designated lanes at night, when the bulk of the work is
expected to occur. The construction is scheduled for nighttime because
less cars are on the road. If funded, the CHP officers will also enforce
reduced speed limits while contractors work on the nets, at times using
lanes to stage workers and equipment. The exact hours of the night work
have not been disclosed. The project is expected to start in 2017 and
finish in 2021.

In March 2017, a completion date for the barrier was
announced: Jan. 12, 2021. Work has already begun. “It may not be
visible on the bridge, but there is already activity going on in the
contractor’s office and in our engineering office,” said Ewa
Bauer, bridge engineer, adding that meetings are occurring about twice a
week on logistics. The first evidence the public will see of the project
is construction of a fence on the span designed to protect workers below,
Bauer said. The project involves installing the equivalent of seven
football fields of netting along the 1.7-mile bridge. The net will be made
of stainless steel, marine-grade cable to stand up to the elements, bridge
officials said. The bridge district’s barrier plan calls for a net
extending 20 feet below and 20 feet from the side of the span, although it
will have to be modified in certain areas because of surrounding terrain.
The net will be gray instead of red to better blend with the water. The
net will not be visible to motorists driving on the bridge, and is
designed to be sensitive to views of and from the span.

In November 2017, it was reported that engineers will
have to do more wind testing on a model of the Golden Gate Bridge before
the span is modified for a seismic upgrade project and a suicide barrier,
officials said. Testing done last month in a Canadian lab (see below)
showed the bridge model performed well under a horizontal wind flow of
more than 100 mph. But the bridge became unstable when the wind flow was
changed by 1 degree, the Marin Independent Journal reported Friday.

In April 2020, it was reported that the Coronovirus
shutdowns of Spring 2020 were not stopping work on the barrier, as
construction of the Golden Gate Bridge suicide barrier is being deemed
essential under the state and local “shelter in place” orders
and will continue during the pandemic, according to the bridge district.
“The net will save about 30 lives a year, so it qualifies as an
exempt project under the orders,” said Paolo Cosulich-Schwartz,
public affairs manager for the Golden Gate Bridge, Highway and
Transportation District. The $211 million project began in August 2018 and
involves 3.5 miles of netting placed 20 feet below the bridge railing and
extending 20 feet out on both sides of the bridge. The net consists of a
mesh of stainless steel and is meant to act as both a life-saving barrier
as well as a visual deterrent. The project is slated for completion in
2023. Advocates of the barrier project have torn views on the
district’s decision to continue construction amid the coronavirus
pandemic: “You want to be careful and you want to protect people in
the pandemic, but you also want to protect people who are suicidal”.
(Source: Marin I-J, 4/8/2020)
In January 2022, it was reported that there were
further delays to the suicide barrier. The suicide barrier project was
originally planned to be completed in January 2021, but was then delayed
to January 2023. Now the district anticipates the barrier won’t be
completed until the end of 2023. District officials say both delays are
the result of the construction contractor, Shimmick Construction Co, who
isn’t working as quickly as the district would like to do the job.
In response, the head of the company, said contractors are “in
discussions with the district about a number of issues that have resulted
in delays.” The delay is expected to add millions of dollars to the
project cost. When the bridge district first put the project out to bid,
officials were shocked when responses were more than double the original
estimate of $76 million. The cost was later revised to $198 million and
then increased to $211 million after the project was delayed until 2023.
Now the district anticipates the cost will be closer to $215 million as a
result of the most recent delays. Construction crews have installed about
240 of the 369 metal support arms that will hold the mesh metal net. The
net is expected to be installed beginning next year.
(Source: Marin I-J, 12/31/2021)
In November 2022, it was reported that the suicide
prevention net will cost about $400 million, more than double its original
price, because of problems sparked by the government agency that manages
the span, the lead contractors allege. The allegations filed Monday in
state court by Shimmick Construction Co. and Danny’s Construction
Co. say that changes to and flaws in the government’s net design and
the lack of transparency about the deterioration of the bridge’s
maintenance platforms have raised the construction price from $142 million
to at least $398 million. The project aims to add 20-foot-wide
(6-meter-wide) stainless steel mesh nets on both sides of the 1.7-mile
(2.7-kilometer) bridge and replace maintenance platforms used by bridge
workers that were built in the 1950s. Work on the net began in 2018 and
was set to be completed by January 2021 but has been repeatedly delayed.
Shimmick Construction Co. and Danny’s Construction Co., which formed
a joint venture to handle the project, were sued last year by
subcontractor Vigor Works, LLC, which claims it’s owed millions of
dollars. The joint venture countersued earlier this year. In the motion
filed this week, they asked a judge to allow them to also sue the Golden
Gate Bridge, Highway and Transportation District, which manages the span.
The contractors contend in the latest court documents that the district
delayed the completion of the project and damaged their reputations by
concealing “significant information ... including extensive
deterioration in certain areas of the bridge.” According to the
joint venture, the deterioration is mainly in the maintenance platforms
— U-shaped structures known as travelers that are powered by diesel
engines and hug the bridge on both sides and bottom to give workers access
to the bridge’s underside and hard-to-reach areas. The joint venture
has completed about 47% of the net and expects to finish it by December
2023, nearly four years behind schedule. Adding the net requires the
maintenance platforms to be reconfigured. The upgraded platforms are not
expected to be completed until January 2026. The contractors claim bridge
officials also changed the design of the net when the project was already
underway and imposed unnecessary requirements on the contractors that
drove costs higher and caused delays. They cited a scaffolding standard
not required by the California Occupational Safety and Health Standards
Board, and said the district failed to obtain a waiver until this February
for the federal requirement to buy the steel needed in the U.S.

In August 2023, it was reported that the new suicide
prevention barrier on the Golden Gate Bridge is having a significant
effect — even though it’s not completed yet. According to
statistics released in July from the Bridge Rail Foundation, a nonprofit
advocacy group that has campaigned for a barrier on the Golden Gate Bridge
since 2006, there have been five confirmed suicide jumps from the bridge
in 2023 through June, compared with 22 from all of 2022. Between 2000 and
2019, the bridge averaged between 30 and 40 suicides per year.
Construction on the suicide prevention barrier — a horizontal net of
steel cables that runs 20 feet below the walkways on both sides of the
bridge — began in 2017 and is expected to be finished by the end of
2023. The net is now over 75 percent complete, and the project cost as of
August 2023 is about $217 million (the cost originally was projected to be
around $76 million), according to the Golden Gate Bridge, Highway and
Transportation District. Two-thirds of the money for the project are
federal funds administered by Caltrans and the Metropolitan Transportation
Commission, and one-third a combination of bridge toll money and funds
from the Mental Health Services Act (California’s Proposition 63,
passed by voters in 2004). The net, made of stainless steel, is
designed not for a cushy landing but rather to inflict a painful, though
non-lethal, injury on a jumper. While one function of the net is hindering
anyone who does land on it from taking further action, the overriding aim
is to deter people from jumping in the first place. Why the barrier seems
to be deterring some people despite being unfinished — there are
wide sections of the railing with a direct line to the ocean —
isn’t entirely clear. Some speculate that areas of the bridge
without a net may be easier for police and the district bridge patrol to
keep an eye on, and that some would-be jumpers who see the net may assume
it goes completely across.

Electronic Tolltaking / Tolls
★★★ ⇒ Information on how to pay the tolls on the Golden Gate Bridge in advance may be found here. This is especially significant if you are in a rental car, for there can be significant surcharges. Those who do not use the bridge frequently can use a one-time payment plan that allows them to use a credit card online or by phone or pay cash in person. Note that drivers do not have the option of paying cash on a Golden Gate Bridge crossing.
In January 2011, it was reported that the Golden Gate
Bridge District was planning to eliminate human tolltakers, replacing them
with electronic toll collection stations. The plan would save $19.2
million over eight years by replacing all 32 toll takers with FasTrak
receivers and video cameras. The cameras would record the license plate of
every driver without a FasTrak transponder and send a bill to the car's
registered owner at the end of the month. Under the plan, the $3.2 million
system would be installed late this year and undergo testing before going
live in December 2012. The electronic toll collection system, when fully
operational, is projected to cost roughly $7.8 million each year, compared
with a cost of more than $10 million each year for the current system.
(Source: San Francisco Chronicle, 1/11/2011)
In March 2013, it was reported that the Golden Gate
Bridge had gone to all-electronic tolling, eliminating the toll-takers.
FasTrak holders, who represent a majority of bridge users, will continue
to have the appropriate toll amounts deducted from their pre-paid
accounts. Motorists who have pay-as-you-go accounts will see that the
amounts are deducted from the credit cards they used to set up the
account. Such accounts can be set up at the bridge district's website, http://www.goldengate.org/tolls/. Drivers who don't have one of those accounts or FasTrak will receive an
invoice in the mail. FasTrak users will continue to pay a discounted toll
of $5. Carpools of three or more people will pay $3, while most everyone
else will continue to pay $6. Payments also can be made at kiosks or with
store clerks at the bridge, gas stations, grocery stores and at other
locations along thoroughfares leading to and from the bridge, at first
including several locations in Santa Rosa and Petaluma. One-time payments,
which also can be made at the district's website, can be made up to 30
days prior to crossing the Golden Gate or 48 hours after doings so. After
that window, an invoice is sent to the vehicle's registered owner.
Motorists have 21 days to pay the toll without penalty. A $25 fine is
tacked on if it is not paid 30 days. The matter is then referred to the
DMV, which can place a hold on the vehicle's registration until the fine
is taken care of.

In June 2015, it was reported that tolls for the Golden
Gate Bridge have increased. For motorists with FasTrack electronic toll
collection devices on the windshield, the Golden Gate Bridge roundtrip
toll rose to $6.25 from $6.00. Many rental cars and ride share vehicles
have FasTrack systems installed. For pay-by-plate motorists, the extra
quarter meant an increase to $7.25. Carpool of three or more get a deal
from 5 a.m. to 9 a.m. and from 4 p.m. to 6 p.m., with a new fare of $4.25.
Additionally, a five-year plan has been announced, calling for an
additional quarter each July in 2016, 2017 and 2018. According to the
Marin Independent Journal, the haul will amount to an extra $138 million
over five years.
(Source: SF Examiner, 6/29/2015)
In October 2015, Governor Brown signed a bill that that
will prevent tolls from being charged to pedestrians and bicyclists on the
Golden Gate Bridge and other state bridges for the next five years. Marin
Assemblyman Marc Levine, D-San Rafael, and Assemblyman Phil Ting, D-San
Francisco, introduced AB 40 earlier this year, which in part, will
“prohibit the district from fixing or collecting any tolls or access
fees for pedestrian and bicyclist use of the Golden Gate Bridge
sidewalks.” Golden Gate Bridge officials initially opposed it, but
lobbied to broaden the language of the bill to make it applicable to all
state bridges even though tolls were not being considered for other spans.
The lawmakers agreed to expand it, and the bridge district then took a
neutral stance on the bill. Golden Gate Bridge officials said they pushed
for the inclusive language out of fairness: If the law applies to one
bridge in the state it should apply to all. The bill was modified again to
cap it at five years, meaning a toll plan could come back after that time.
It then was approved by the Legislature. About a decade ago the bridge
board considered charging tolls to bicyclists and pedestrians, but it
backed away from the plan after protests from bike groups. At that time it
was estimated such a toll could raise $500,000 to $1.5 million annually.

In August 2016, it was reported that Golden Gate Bridge
officials may be removing the toll plaza that has been part of the bridge
since it opened in 1937. The plaza would be replaced with a large
gantry-type structure. In 2000, a much ballyhooed $7 million FasTrak
electronic toll system came online at the bridge's toll plaza. At the time
toll takers still worked at the span and drivers had the option of paying
with cash or electronically. Because there were two functions, the FasTrak
equipment was hard-wired into the toll booth structure. In 2013, toll
takers were eliminated in a cost-cutting measure and in the passing years
the FasTrak equipment has become outdated. Additionally, the cameras,
lights and other FasTrak equipment has become the unintended target of
vehicles crashing into the apparatus in the plaza's narrow lanes. The
state is also developing new rules for electronic toll systems that the
span's current equipment doesn't meet. Rather than put new equipment in
the old toll plaza, bridge officials are looking to erect a gantry a few
hundred feet south of the toll plaza to be placed over southbound lanes by
December 2018. The new technology is the toll gantry, on which lasers,
lights and cameras are hung to assess tolls. While sophisticated, the new
equipment would not be able to count passengers, keeping the three-person
carpool regulations somewhat on the honor system, although enforced by the
California Highway Patrol. Officials looked around the toll plaza for the
optimal gantry site and settled on an area just south of the toll plaza
across from the bridge district administration building parking lot. Color
of the gantry and design still need to be determined. There are no plans
currently to demolish the toll plaza, meaning the art deco clock at the
span will keep its home for the time being.
(Source: East Bay Times, 8/28/2016)
In August 2017, it was reported that a large
gantry-type structure project is moving forward as Golden Gate Bridge
officials look to upgrade toll collection machinery. The bridge district
has hired Oakland-based consultant AECOM for roughly $1 million to design
the gantry, which will be built south of the existing toll plaza. The
entire project will cost about $7 million. The technology at the toll
plaza was put in two years before the first iPhone was put out, and is
quite dated. In 2000 the FasTrak electronic toll system came online at the
bridge’s toll plaza. At the time toll takers still worked at the
span and drivers had the option of paying with cash or electronically.
Because there were two functions, the FasTrak equipment was hard-wired
into the toll booth structure. But in 2013, toll takers were eliminated in
a cost-cutting measure and in the passing years the FasTrak equipment has

equipment has become the unintended target of vehicles crashing into the
apparatus in the plaza’s narrow lanes. The state is also developing
new rules for electronic toll systems that the span’s current
equipment doesn’t meet. Rather than put new equipment in the old
toll plaza, bridge officials are looking to erect a gantry by Jan. 1,
2019. The gantry will have motion sensors, antennas, lights and cameras to
assess tolls. That puts most equipment above the roadway, allowing
maintenance to occur without lane closures. "The limited vertical
clearance and configuration of the existing toll booths structure cannot
support the new technology, so a new support structure is required,”
reads a report on the gantry. The new support structure will be a single
steel gantry supported by concrete foundations, located approximately 200
feet south of the toll booths and spanning over all southbound lanes.
About 20 million cars pass southbound over the span each year. AECOM was
hired last month to design the structure. While sophisticated, the new
equipment would not be able to count passengers, keeping the three-person
carpool regulations somewhat on the honor system, although enforced by the
California Highway Patrol. There are no plans for the existing toll plaza.
That will part of a separate project that has not entirely come into
focus. For now, that means the art deco clock at the span will keep its
home. Officials have indicated that, at some point, they may look to
reconfigure the toll plaza; however, the clock would remain at the span if
that occurred.

In December 2017, it was reported that a new way for
Golden Gate Bridge officials to collect tolls will be in place by 2020. A
large gantry-type structure project is moving forward as Golden Gate
Bridge officials look to upgrade toll collection machinery. Earlier this
year, the bridge district hired Oakland-based consultant AECOM for roughly
$1 million to design the 20-foot-high gantry, which will be built 140 feet
south of the existing toll plaza. The entire project will cost about $7
million. Input will be sought from community groups for the final design.

In April 2018, it was reported that Golden Gate Bridge
directors have decided to replicate the slender, curved Art Deco look of
the span’s light poles on a new overhead toll gantry that will be
built over the southbound lanes of traffic near the administration
building to electronically collect tolls. The vote for the design, one of
three being considered, was unanimous. The others mimicked the
bridge’s main cable and the rounded shape of the landmark’s
former tollbooth, which has been taken out of service. A toll gantry,
typically an industrial-looking gray steel structure, holds the technology
and gadgetry used to collect tolls electronically. But Golden Gate
officials didn’t want to mar or distract from the landmark span.
They had architects design structures that sported the bridge’s
international orange hue, were as light and unobtrusive as possible, and
reflected, in some way, the bridge’s look and feel. Construction
will take place in 2019, and the gantry will start collecting tolls in
2020.

Golden Gate Seismic Retrofitting
The Golden Gate Bridge seismic project began in 1998. Initially the work was to have cost roughly $300 million but has since increased to more than $900 million as prices have gone up over time and bridge officials were forced to further gird the bridge after the 9/11 attacks.
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $8,800,000 for High Priority Project #429: Seismic retrofit of the Golden Gate Bridge. Note that the Golden Gate Bridge is not part of US 101. This appears to be supplemental funding for TCRP Project #143, and might even be a kickstart for that project, as it hasn't been discussed at the CTC level. The funding is likely insufficient, being cut down from the requested $11M.
In September 2011, it was noted that in 2013, the GG Bridge District will face a $75 million payout to help with construction of the new Doyle Drive and $100 million in seismic strengthening costs for its span. Between 2001 and 2011, the district has whittled its deficit from $454 million, then to $132 million and as of 2011 to $87 million by raising bridge tolls, issuing layoffs and cutting bus service, among other steps. However, inflation, capital projects and other factors will require the district to continue to take steps to reduce costs over the next several years. That includes a plan to eliminate all toll-takers on the span late next year, as the bridge goes to all-electronic tolling.
In May 2012, it was reported that the retrofitting
includes replacing the roadway on top of the anchorage house. The work is
being accomplished by workers cutting out 25-by-10-foot segments and
replacing them with 78, new 38,000-pound prefabricated segments over the
course of 300 feet. It is the first time the road over the anchorage house
has been replaced since the bridge opened 75 years ago. Most of the span's
roadway was replaced in 1986, but at that time the technology was not
available to easily pull the road up and off of the anchorage house.
That's because the roadway also serves as the roof and ceiling of the
anchorage house, the box-like structure the length of a football field at
the north end of the bridge, which holds all the cables coming off the
span that tie down the structure. Once it is in, the new roadway will be
sealed, so water does not get into the anchorage house, as well as paved
for a smooth finish. Work on the latest phase of seismic work in the
anchorage house also included utility relocation, strengthening existing
and building new concrete walls, as well as putting in a stronger
foundation with micro piles. They are also replacing the support towers.
Work on the first phase of the seismic project, strengthening the north
approach, was finished in spring 2002. Work on the second phase, along the
south approach, was finished in 2007. Work for the final "Phase 3B"
— addressing the anchorage house and the center suspension portion
of the span — will cost $200 million and bridge officials are
seeking funding for that work in Washington D.C. All work could be
finished by 2018.
(Source: Marin Independent Journal, 4/29/2012)
Seismic work on the northern approach, southern
approach and the north anchorage house — the box-like structure that
holds all the cables coming off the span that tie down the bridge —
has been completed. As of October 2017, the bridge is considered safe,
with officials saying the north and south ends could sustain an 8.3-scale
quake. The center suspension segment was saved for last because it is
least susceptible to collapse in a major quake, bridge officials said. The
final phase of the seismic effort is pegged between $450 million and $500
million. The suspension section could withstand a large earthquake, bigger
than a 7.0, but there would be extensive damage and the bridge would
likely have to be closed for a long period. Currently, bridge officials
are working to seismically strengthen the center portion of the span and
wind testing is a key element of the work. Engineers are always concerned
that any modification to a bridge, however slight, could affect how it
performs in high winds. Seismic work on the center suspension portion of
the span will involve platforms and the replacement of a top lateral
bracing system. That will require installation of temporary bracing
supports to maintain structural integrity and load carrying capacity of
the span. Bridge engineers want to conduct wind tests to make sure the
temporary pieces and platforms can survive the sometimes howling winds
that can slam into the bridge deck that sits 220 feet above the water.
About 110,000 people use the span daily.

In September 2023, it was reported that Golden Gate
Bridge officials were preparing to launch the final and largest phase of a
decadeslong project to make the 85-year-old structure withstand stronger
earthquakes. The Golden Gate Bridge, Highway and Transportation District
plans to select a construction contractor later in 2023 to begin
preliminary work on the estimated $880 million final phase. The project
will upgrade the main span and the towers and allow the bridge to
withstand a magnitude 8.3 quake, which would be comparable to the
destructive 1906 San Francisco earthquake. The seismic retrofit project,
which was launched in 1997, was prompted by the Loma Prieta earthquake in
1989. The 15-second, 6.9-magnitude quake caused major damage to bridges
and highways, including the collapse of the top deck of the Bay Bridge and
the Cypress Street viaduct in Oakland. The Golden Gate Bridge had no
observable damage but was located about 60 miles north of the
quake’s epicenter. A vulnerability study conducted by the bridge
district after the Loma Prieta earthquake found that a magnitude 7.0 quake
with an epicenter near the bridge could cause major damage to the span. A
magnitude 8.0 temblor would create a substantial risk of collapse at the
two viaducts on the San Francisco and Marin entry points as well as at the
Fort Point Arch. About $260 million in seismic upgrades were completed at
these vulnerable sections of the bridge from 2001 to 2014. District staff
said the bridge no longer faces the risk of collapse at these sections,
but the main suspension bridge still faces the risk of significant damage.
The final phase will install 38 devices to absorb quake energy that would
otherwise flow into the bridge. Special joints will be added to the sides
of each tower and near the pylons at each edge of the main span that allow
for three-dimensional movement. Construction crews will also strengthen
structures themselves, including the road deck and the bases of the tower,
to minimize the input of seismic energy and thereby reduce damage. Three
contractors have submitted applications for the project in response to a
request sent out in May. The district’s board is expected to select
a contractor and begin a yearlong process to work through each step of the
construction to set prices, timelines and other details. The final
retrofit project still has a substantial funding gap that must be closed
before its planned 2025 construction start. About $451 million of the $880
million has been raised, with the majority of that funding coming from the
$1.1 trillion federal infrastructure legislation of 2021. The price is
about $1.4 million higher than originally estimated and could increase
further in 2024. The district aims to close the funding gap through state
funds.

Median Barrier / Zipper Barrier / Lane Configurations
In September 2013, is was reported that after 15 years
of planning and searching for funding, the bridge district's Board of
Directors approved the purchase of the $26.5 million barrier - designed to
prevent head-on collisions. The barrier would be installed in late October
or early November of 2014 during a 52-hour weekend closure. Lindsay
Transportation Systems would build the barrier at 12 inches wide, 32
inches tall and 11,538 feet long. It would consist of steel walls filled
with compressed concrete in attached segments that would be moved with a
pair of "zipper trucks" to adjust lane configurations on the six-lane
span.
(Source: SFGate, 9/19/13)
In January 2016, it was reported that the lane
configuration on the bridge would be changing. The 2015 configuration of
four northbound lanes and two southbound lanes will be altered beginning
Jan. 4, 2016. On Monday, Tuesday and Wednesday afternoons, there will be
three southbound and three northbound lanes on the span — a move the
Golden Gate Bridge, Highway & Transportation District made after
analyzing traffic data. The change comes after the bridge district decided
in September to consistently go with four northbound lanes as part of a
pilot project. The 2015 configuration will remain on Thursday and Friday
afternoons — from 4:30 p.m. to 5:30 p.m., a bit shorter than
before.The district said it will analyze the lane change and its impact on
traffic in April.

In March 2020, it was reported that the Median Barrier
has stopped what was once an alarming trend of head-on collisions. There
have been no head-on crashes on the span since the bridge district
installed the barrier in 2015. That’s down from an average of about
2.8 per year. Between 1970 and 2015, there were 128 head-on collisions on
the bridge. Those resulted in 16 deaths and dozens of serious injuries.
Before the barrier, north and southbound traffic was separated by flimsy,
yellow tubes that were a few inches taller than a bowling pin. Workers
hanging off a truck placed the rubber tubes by hand along the roadway
every 25 feet. The $30 million median barrier, made of concrete and steel,
is 32 inches high and a foot wide. It’s moved three times each day
by workers driving yellow “zipper” trucks in accordance with
commute patterns. The barrier rests on the bridge with gravity holding it
in place, but is strong enough to absorb major impacts without moving
because of an internal spring system. On several occasions, cars have hit
the barrier. Officials noted that it’s likely those accidents could
have been disastrous if the separator wasn’t in place. The downside
to the barrier is that it has emboldened some drivers who apparently feel
more comfortable driving in excess of the bridge’s 45 mph speed
limit. Though there haven’t been any head-on collisions, there has
been a “slight uptick” in the number of traffic accidents
overall since the barrier was installed. Most of them, he noted, have been
“minor and without injury.”

The Bridge Sings
In June 2020, it was reported that a recent bicycle
path and railing retrofit has resulted in the Golden Gate Bridge sounding
"like an orange wheezing kazoo". Paolo Cosulich-Schwartz, a Golden Gate
Bridge, Highway & Transportation District spokesperson, said the
sounds stemmed from long-planned wind retrofitting. “The new musical
tones coming from the bridge are a known and inevitable phenomenon that
stem from our wind retrofit project during very high winds. The wind
retrofit project is designed to make the Bridge more aerodynamic under
high wind conditions and is necessary to ensure the safety and structural
integrity of the Bridge for generations to come. We knew going into the
handrail replacement that the bridge would sing during exceptionally high
winds from the west, as we saw yesterday. We are pleased to see the new
railing is allowing wind to flow more smoothly across the bridge,”
Cosulich-Schwartz said. Specifically, the sound is the result of fast
northwesterly winds passing through new railings and wind fairings on the
western side between the two towers as part of on ongoing wind retrofit
project. It has been described by the district as “singing,”
but some local residents had other choice words, calling it screeching
that sounded like torture and saying it caused such physiological distress
that it was impossible to ignore. After the noise became noticeable at the
beginning of June, the district put out a statement on June 6 stating that
the “new musical tones coming from the bridge are a known and
inevitable phenomenon that stems from our wind retrofit project during
very high winds.” Later, the district walked back those comments.

District staff spoke with a consultant to discuss plans
to study the cause of the noise and develop changes to potentially muffle
it. In the meantime, they plan to record the sound and compare it to their
weather station data to create a baseline record of when and under what
conditions the noise occurs. The wind retrofit is being performed to
ensure the bridge can withstand winds of up to 100 miles per hour. It is
also required as part of the installation of the bridge’s suicide
barrier that is under construction. About 75% of the new railings have
been installed and about 10% of the wind fairings. The project’s
final environmental impact report, published in 2010, found that the new
railings and fairings would not result in any substantial increase in
ambient noise compared to before its installation. The EIR results were
based on expert analysts who conducted multiple tests on a 1:20 scale
model of the bridge. The model bridge was constructed of aluminum and
plastic, however, not of steel as it is on the actual bridge.

In January 2022, it was reported that engineers have
developed a $450,000 plan to muffle the loud humming noise that has been
emanating from the Golden Gate Bridge on windy days. The sound was an
unintended result of wind upgrades on the bridge railing in 2020.
Residents living in nearby communities such as Sausalito and San
Francisco’s Presidio area were most affected, but the strange
humming could be heard from several miles away. The noise is generated by
fast northwesterly winds passing through the new railings and wind
fairings that were installed on the western side between the two towers.
After studying the sound for the last year, the bridge’s governing
agency recently approved a plan that its chief engineer, Ewa
Bauer-Furbush, said will “significantly reduce and in very many
instances will eliminate the noise.” The plan calls for installing
thin U-shaped aluminum clips with rubber inserts on the railing pickets
along the entire span of the bridge. The bridge district hopes to have the
clips installed by the end of 2022, but much of that will depend on how
quickly the materials can be fabricated. Surveys of the bridge found that
the noise could reach as high as 100 decibels, which is similar to the
sound of a jackhammer or garbage truck. Wind tunnel tests conducted by the
district have shown that the clips reduce most of the wind noise by 10 to
40 decibels. A 10-decibel reduction results in the sound being half as
loud to the human ear. After the noise became noticeable in June 2020, the
district issued a statement saying the “new musical tones coming
from the bridge are a known and inevitable phenomenon that stems from our
wind retrofit project during very high winds.” The wind upgrades
were installed as part of the ongoing suicide barrier project on the
bridge. The barrier will be located on both sides of the bridge and will
include a mesh metal net that officials say will serve as a deterrent. The
wind retrofit was required to allow the bridge the millions of pounds of
extra weight from the steel barrier.

The following portions of this are currently constructed to freeway standards: (1) from Route 5 to 4 miles west of Ventura, ending at Sea Cliff (approx 80 miles); (2) from Punta to the western city limits of Goleta (approx 17 miles); (3) near Rufgio St Beach (approx 5 miles); (4) from Gaviota to Solvang (approx 20 miles); (5) from Route 176 to Nipomo (approx 19 miles); (6) from Arroyo Grande to 1 mile north of San Luis Obispo (approx 17 miles); (7) from Santa Margita to Paso Robles (approx 19 miles); (8) from San Miguel to 2 miles north of King City (approx 22 miles); (9) through Salinas (10 miles); (10) from Gilroy to San Jose (33 miles); (11) the Bayshore Freeway in San Jose to San Francisco.
In San Mateo County, a HOV lane runs (in both directions) from Whipple Avenue to the Santa Clara county line, for a length of 6.6 mi. This was opened in July 1991. It requires two or more occupants, and operates on weekdays during the following hours: 5:00-9:00AM, 3:00-7:00PM.
In Santa Clara County, a HOV lane runs (both directions) from the San Mateo county line to the vicinity of Bernal Road, for a length of approximately 25 miles. The portion between the San Mateo County Line and Guadalupe Parkway was opened in November 1986 and extended twice in 1988; the portion between Guadalupe Parkway and Route 280 was opened in April 1993; and the portion between Route 280 and Bernal Road was opened in June 1990. All require two or more occupants, and operate on weekdays during the following hours: 5:00-9:00AM, 3:00-7:00PM.
With respect to usage: A 2001 Caltrans survey showed that use of the HOV lane in the San Francisco Bay Area fell from 14,110 vehicles in 1996 to 9,093 in 2001. During the busiest hour of the morning, more than 1,500 cars used the HOV lane, which is about the same number of cars as in each non-carpool lane. Note that the 2001 survey showed that US 101 has the distinction of the slowest speed for carpoolers at 28 mph during the afternoon.
There are plans to add a reversible HOV lane through San Rafael from Sir Francis Drake Blvd to N San Pedro Road in Marin County. This is TCRP Project #17, requested by the Marin Congestion Management Agency together with Caltrans. In August 2005, this was amended to be two HOV lanes, instead of a single reversable lane.
There also appear to be plans to address the HOV gap between south of the Coleman School Pedestrian Overcrossing to North San Pedro Road Undercrossing.
Between the intersection with Boronda Road and the intersection with the San Benito-Monterey County line. Authorized by Senate Bill 155, Chapter 169, on July 23, 1999.
The Golden Gate Bridge, per Senate Bill 988, Chapter 593, September 29, 2006.
Route 101 between Golden Gate Avenue and Lyon Street in the City and County of San Francisco, per Senate Bill 1491, Chapter 121, July 10, 2008.
Historically, this route is close to the original "El Camino Real" (The Kings Road). This route (from Route 5 to Route 82) has officially been designated as "El Camino Real by Assembly Bill 1769, Chapter 1569, in 1959. Note that there are other roads that are likely the original El Camino Real, in particular, portions of Monterey Road from S of Gilroy to downtown San Jose.
The segment of US 101 from Route 110 to Route 2 is part of "Historic Highway Route 66", designated by Assembly Concurrent Resolution 6, Chapter 52, in 1991.
The I-5/I-10/Route 60/US 101 interchange, commonly referred to
as the East Los Angeles Interchange (~ 101 LA S0.117), is named the
“Medal of Honor Recipient , Eugene A. Obregon, USMC, Memorial
Interchange” (it was originally named the “Marine
Private First Class Eugene A. Obregon Interchange”). This
interchange was named in memory of Medal of Honor Recipient Eugene A.
Obregon, USMC. While serving as an ammunition carrier with Golf Company,
Third Battalion, Fifth Marine Regiment, First Marine Division
(Reinforced), during the Korean War, PFC Obregon was killed in action on
September 26, 1950. The machine-gun squad of Private Obregon was
temporarily pinned down by hostile fire; and during this time, he observed
a fellow marine fall wounded in the line of fire. Armed only with a
pistol, Private Obregon unhesitantly dashed from his cover position to the
side of the fallen marine. Firing his pistol with one hand as he ran,
Private Obregon grasped his comrade by the arm, and despite the great
peril to himself, dragged the marine to the side of the road. Still under
enemy fire, Private Obregon was bandaging the marine's wounds when hostile
troops began approaching their position. Quickly seizing the wounded
marine's rifle, Private Obregon placed his own body as a shield in front
of the wounded marine and lay there firing accurately and effectively into
the approaching enemy troops until he, himself, was fatally wounded by
enemy machine-gun fire. By his courageous fighting spirit, and loyal
devotion to duty, Private Obregon enabled his fellow marines to rescue the
wounded marine. By fate and courage, Private Obregon is one of the valiant
Mexican Americans to receive the Congressional Medal of Honor, the
nation's highest military honor for bravery. Named by Senate Concurrent
Resolution (SCR) 109, Resolution Chapter 66, on 6/26/2008.

his associate degree in fire technology, graduated with academic honors,
and was recognized for his stewardship in the local community; and went on
to receive his Bachelor of Science from Columbia Southern University, with
a concentration in fire systems. Wong continued on to graduate and become
a firefighter with the Los Angeles Fire Department on August 20, 2015,
Drill Tower 40, Class 14-2, earning distinction in the firefighting
academy and being named the Top Academic Recruit of his graduating class.
In his free time, Kelly Wong enjoyed the outdoors, traveling, as well as
learning new subjects and problem solving, and he was an avid aviation
enthusiast who was in the process of obtaining his fixed wing private
pilot rating from Universal Air Academy at Brackett Field Airport. Kelly
Wong was just starting his career as a two-year veteran of the Los Angeles
Fire Department, assigned to Fire Station 92 in Rancho Park and about to
be transferred to Fire Station 9, the Downtown and Skid Row station when,
on June 3, 2017, while participating in a training exercise in downtown
Los Angeles, he unfortunately fell from an aerial ladder and suffered
critical injuries. On June 5, 2017, Kelly Wong succumbed to those
injuries. Named by Senate Resolution SCR 78, Res. Chapter 105, 08/01/22. However, the sign was put up in June 2021, over a year before the naming resolution was signed.

Officially, the segment of US-101 from Rout 110 (~ 101 LA 1.569) to Route 134 (~101 LA 11.733R) is named the "Hollywood
Freeway". The first segment of the Hollywood Freeway opened in 1940
(as the Hollywood Expressway); the last segment opened in 1948. As for the
origin of the name Hollywood, many different stories can be found. A
popular explanation is that it was the name given by the wife of founder
Horace H. Wilcox who named it after the "Mass of the Holy Wood of the
Cross" said by Father Junipero Serra near the site. It may have also been
a name borrowed from one of the Hollywoods of the east.

The portion of US 101 between Hollywood Boulevard (101 LA 6.520)
and Cahuenga Boulevard (101 LA 7.459), in the County of Los Angeles, is
named the "Los Angeles Police Officer Ian J. Campbell Memorial Highway"
(signed as "LAPD Police Officer..."). It was named in memory of
Los Angeles Police Officer Ian J. Campbell, who was born in Valley City,
North Dakota. His father was a doctor who served honorably in World War I.
Officer Campbell's parents were of Scottish descent. At 13 years of age,
after his father died of cancer, Campbell and his mother moved to Los
Angeles. Officer Campbell attended and graduated from Fairfax High School,
and then attended Los Angeles City College. At approximately 12 years of
age, Officer Campbell started playing the bagpipes, taking lessons from
renowned Pipe Major David Aitken, winning best bagpiper in the novice
category at the Scottish Highland Games held in Santa Monica. At 19 years
of age, Officer Campbell enlisted in the United States Marine Corps, where
he was trained as a radio operator, served two combat tours during the
Korean War, and was honorably discharged from the Marine Corps as a Staff
Sergeant, having been awarded the Marine Corps Good Conduct Medal,
National Defense Service Medal, Korean Service Medal with four bronze
stars, and the United Nations Korean Service Medal. Upon his discharge
from the Marine Corps, Officer Campbell returned to Los Angeles and
attended undergraduate school at the University of California at Los
Angeles. Officer Campbell entered the Los Angeles Police Academy and, on
May 5, 1958, he graduated from the academy, successfully completing his
probationary period as a Los Angeles police officer while assigned to the
West Los Angeles Police Station, thereafter being transferred to the
Hollywood Division of the Los Angeles Police Department (LAPD). On March
9, 1963, Officer Campbell was conducting a stop of a suspicious vehicle at
Gower Street and Carlos Avenue in Hollywood when he was kidnapped at
gunpoint, forcibly taken to a deserted onion field south of Bakersfield,
and executed. Officer Campbell was 31 years of age at the time of his
death and had served the LAPD for five years. On March 13, 1963, bagpipes
were played for the first time for an officer of the LAPD at the funeral
of Officer Campbell, a tradition that continues to this day following the
line-of-duty death of every LAPD officer. On June 26, 1965, as a memorial
to Officer Campbell, the Ian Campbell Memorial Trophy was awarded to the
best aggregate bagpiper in the novice category at the Scottish Highland
Games, a tradition that continues to this day. Named by Assembly
Concurrent Resolution 100, Resolution Chapter 109, on September 4, 2012.
In March 2013, signs honoring Officer Campbell, whose slaying by
kidnappers was chronicled in the book and movie "The Onion Field," were
placed alongside the Hollywood Freeway to mark the 50th
anniversary of the famous case.

The interchange of the U 101, Route 134, and Route 170 freeways (~101 LA 11.733R) is named the "Bruce
T. Hinman Memorial Interchange." Officer Bruce T. Hinman was on
routine motorcycle patrol on Route 170 at US 101 when he stopped to assist
a disabled motorist. A drunk driver traveling at 60 m.p.h. along US 101
attempted to change routes by driving over a raised berm, then across the
freeway and onto the dirt shoulder where he crashed into the disabled
vehicle. The impact spun the disabled vehicle around, striking the
motorist, who was using the freeway call box, and knocking Officer Hinman
to the ground. The car came to rest with its rear wheels on top of the
officer's chest, suffocating him. Officer Hinman, 34, was placed on life
support but died a week later. He was a nine-year member of the CHP and
was assigned to the West Valley Area office directly after graduating from
the Academy. CHP Officer Bruce Hinman, an eight-year CHP veteran, was said
to be the first officer in the 26-year history of the patrol's West Valley
station to die in the line of duty.

The portion of US 101 between the Laurel Canyon Boulevard
exit on US 101 and the interchange with Route 134 (~ LA 11.866R to LA
12.88) and portion of Route 134 from the interchange with US 101 to the
North Pass Avenue exit on Route 134 (~ LA 0.000 to LA 1.798) in the County
of Los Angeles is named the “Amelia Earhart Memorial Highway”.
It was named in memory of Amelia Earhart, who was born on July 24, 1897,
in Atchison, Kansas. After graduating from Hyde Park High School in 1915,
Earhart attended Ogontz, a girl’s finishing school in the suburbs of
Philadelphia. Earhart left Ogantz in the middle of her second year to work
as a nurse’s aide in a military hospital in Canada during World War
I, attended college, and later became a social worker at Denison House, a
settlement house in Boston. Earhart took her first flying lesson on
January 3, 1921, and, in six months, managed to save enough money to buy
her first plane, a second-hand Kinner Airster two-seater biplane painted
bright yellow, which she named “The Canary,” and used to set
her first women’s record by rising to an altitude of 14,000 feet. In
1928, Earhart was asked to join pilot Wilmer “Bill” Stultz and
copilot and mechanic Louis E. “Slim” Gordon as part of a
project to be the first woman to fly across the Atlantic Ocean. On June
17, 1928, the team left Trepassey Harbor, Newfoundland, in a Fokker F7
named Friendship, and arrived at Burry Port, Wales approximately 21 hours
later. Their landmark flight made headlines worldwide because three pilots
had died within the year trying to be the first woman to fly across the
Atlantic. When the crew returned to the United States, they were greeted
with a ticker-tape parade in New York and a reception held by President
Calvin Coolidge at the White House. Earhart and George Putnam, a book
publisher and publicist, developed a friendship during preparation for the
Atlantic crossing and were married on February 7, 1931. Intent on
retaining her independence, she referred to the marriage as a
“partnership” with “dual control”. Together,
Earhart and Putnam worked on secret plans for Earhart to become the first
woman and the second person to fly solo across the Atlantic and on May 20,
1932, five years to the day after the Lindbergh flight across the
Atlantic, she took off from Harbor Grace, Newfoundland, to Paris; alas
strong north winds, icy conditions, and mechanical problems plagued the
flight and forced her to land in a pasture near Londonderry, Ireland. As
word of her flight spread, the media surrounded her, both overseas and in
the United States. President Herbert Hoover presented Earhart with a gold
medal from the National Geographic Society and Congress awarded her the
Distinguished Flying Cross-the first ever given to a woman. At the
ceremony, Vice President Charles Curtis praised her courage, saying she
displayed “heroic courage and skill as a navigator at the risk of
her life”. Earhart felt the flight proved that men and women were
equal in “jobs requiring intelligence, coordination, speed,
coolness, and willpower”. In the years that followed, Earhart
continued to reach new heights, setting an altitude record for autogyros
of 18,415 feet that stood for years and on January 11, 1935, she became
the first person to fly solo across the Pacific Ocean from Honolulu to
Oakland, California. In 1937, as Earhart neared her 40th
birthday, she was ready for a monumental, and final, challenge: she wanted
to be the first woman to fly around the world. On June 1, 1937, Earhart
and her navigator, Fred Noonan, departed from Miami and began the
29,000-mile journey around the world and by June 29, when they landed in
Lae, New Guinea, all but 7,000 miles had been completed. On July 2, 1937,
the pair embarked on a 2,556 mile flight from Lae, New Guinea to Howland
Island. During this flight they encountered difficult conditions for
navigation and Earhart lost radio contact the following morning with a
nearby United States Coast Guard ship. Earhart’s plane disappeared
and nothing further was heard from her. The world will always remember
Amelia Earhart for her courage, vision, and groundbreaking achievements,
both in aviation and for women. In a letter to her husband, written in
case a dangerous flight proved to be her last, her brave spirit was clear.
“Please know I am quite aware of the hazards,” she said.
“I want to do it because I want to do it. Women must try to do
things as men have tried. When they fail, their failure must be but a
challenge to others”. Named by Assembly Resolution ACR 79, Res. Chapter 121, 08/19/22.

The portion of US 101 between the junction with I-405, at LA 17.165 and Balboa Boulevard, at
LA 19.217, is named the “Dr. Sally Ride Memorial Highway”.
Sally Ride was born in the City of Los Angeles, California, and raised in
the City of Encino, California. As a child, Sally was a gifted tennis
player who dreamed of playing professionally, and eventually earned a
scholarship to Westlake School for Girls in the City of Los Angeles, where
she graduated in 1968. Upon graduating from high school, Sally attended
Swarthmore College for a year and one-half, and then transferred to
Stanford University, where she received a Bachelor of Science degree in
physics and a Bachelor of Arts degree in English in 1973. She continued at
Stanford University, earning her Master of Science and doctorate degrees
in physics in 1975 and 1978. In 1977, Sally answered a Stanford University
student newspaper article placed by the National Aeronautics and Space
Administration (NASA) announcing that, for the first time, women could
apply to the astronaut corps. One year later, Sally was selected as one of
only six women for NASA’s astronaut class of 1978. After completing
her training, Sally started her aeronautics career on the ground, serving
as a capsule communicator as part of the ground-support crew for the
second and third space shuttle flights. In June 1983, Sally was one of
five crewmembers aboard the space shuttle Challenger, where she became the
first American woman to fly in space, and the youngest American in space,
and she flew on Challenger again in 1984. After her career as an astronaut
ended, Sally became a professor of physics and served as the Director of
the California Space Institute at the University of California, San Diego;
as a member of the President’s Committee of Advisors on Science and
Technology and on the Advisory Board of the National Women’s History
Museum. Sally passed away on July 23, 2012, after a 17-month battle with
pancreatic cancer. Named by Assembly Resolution ACR 51, Res. Chapter 114, Statutes of 2021, 09/07/21.

Sergeant Ron Helus was shot after responding to an active shooter at the
Borderline Bar and Grill in Thousand Oaks and passed away on November 8;
Ron was approximately one year from retiring from the Ventura County
Sheriff’s Department. The incident occurred whenSergeant Helus heard
gunfire coming from inside the bar, which was occupied by nearly 200
college students, and he and a California Highway Patrol officer made the
courageous decision to enter the bar and immediately confront the shooter
to protect as many civilians as possible. Named by Assembly Concurrent
Resolution 17, Resolution Chapter 120, 7/23/2019.
Background: The effort to name this segment started in
2018. It was reported in November 2018 that there was work afoot to name
some portion of US 101 in Camarillo or Thousand Oaks (~ VEN 4.079) after
Ventura County sheriff’s Sgt. Ron Helus, one of 12 people killed by
a gunman in the Borderline Bar & Grill mass shooting Nov. 7., 2018.
The city has been in talks with Irwin, D-Thousand Oaks, to introduce a
resolution asking the Legislature to approve naming a portion of the 101
at Moorpark Road near the Borderline in Helus’ honor. The 29-year
veteran of the Ventura County Sheriff’s Office was killed after he
heard gunfire inside the bar the night of Nov. 7 and entered the
establishment to confront the gunman. Irwin, a former Thousand Oaks City
Council member, said Wednesday she expects to introduce her resolution in
January and anticipates it being approved without issue. She said she
hopes to get the signs up honoring Helus in a year. The Thousand Oaks City
Council voted unanimously to support dedicating that portion of US 101 in
Helus’ honor.

The portion of Route 101 from the top of the
Conejo Grade (~ 101 VEN 5.934) to Lewis Road (~ VEN 13.803) in the City of
Camarillo is named the "Adolfo Camarillo Memorial Highway." Named
in honor of Adolfo Camarillo, born in 1864 in what would become Ventura
County. In 1880, at 16 years of age, took over operations of the 10,000
acre Rancho Calleguas upon the death of his father Juan. Adolfo Camarillo
married Isabella Menchaca in 1888 and they moved into an adobe on the
ranch and subsequently raised five children. In 1890, Adolfo Camarillo
planted two rows of eucalyptus trees, with the help of two Chumash
Indians, which arched over what became Route 101 for many years. These
trees were designated as Ventura County Historical Landmark Number 3 on
August 5, 1968, and were identified as the Adolfo Camarillo Heritage Grove
in the Negative Declaration for the widening of Route 101 through
Camarillo in 1980. In 1892, Adolfo Camarillo constructed the Queen Anne
Victorian Camarillo Ranch House, which is visible to the north from Route 101 and was recommended for designation as a California Point of
Historical Interest by the State Office of Historical Preservation on
August 5, 2005, and was approved for that designation by the State
Director of Parks and Recreation on September 29, 2005. Adolfo Camarillo
graduated from the International Business College in Los Angeles in 1895
and was a pioneer in raising lima beans, which became the major crop in
Ventura County during that time. He served as a member of the Board of
Supervisors of Ventura County from 1907 to 1915. He was a member of the
Pleasant Valley School District Board of Trustees for 56 years, serving as
presiding officer for a total of 23 years. Adolfo Camarillo donated
property for the Southern Pacific Railroad to be constructed through
Camarillo in 1898 and this resulted in a station being built that became
known as "Camarillo," and the town site for Camarillo was laid out that
same year. He gave to the community by donating 50 acres of land for the
first high school in Camarillo, which is named for him, and granted land
for the new Conejo Grade Route 101 project in 1937, enabling the highway
to be constructed across the entire width of the original Rancho Calleguas
from the Conejo Grade to the Union Pacific Railroad, formerly the Southern
Pacific Railroad, tracks adjacent to downtown Camarillo, He was a leader
in a number of organizations in Camarillo and California, including the
Ventura County Fair Board, the Camarillo Chamber of Commerce, Los
Rancheros Visitadores, and the California Lima Bean Growers Association.
He was a director of the California State Fair Board and of the Bank of A.
Levy. He also bred and raised a stable of Morgan-Arabian horses, now
famously known as the "Camarillo White Horses," which represented the
community at many events, including the Pasadena Rose Parades and the
opening of the Oakland Bay Bridge in 1936, and were ridden by him at many
Los Rancheros Visitadores trail rides. Adolfo Camarillo was known
affectionately as "The Last Spanish Don" because he cherished and
preserved the Spanish traditions of early California. Named by Assembly
Concurrent Resolution (ACR) 116, Resolution Chapter 74, on 7/3/2008.

The 2.040-mile portion of US 101 between
Lewis Road/Junction Route 34 at 101 VEN 13.848 and Las Posas Road at 101
VEN 15.888 in the County of Ventura is named the "Deputy Sheriff
Yevhen “Eugene” Kostiuchenko Memorial Highway". It was
named in memory of Ventura County Deputy Sheriff Yevhen
“Eugene” Kostiuchenko,born in Kiev, Ukraine, in January 1973.
One of two children, Kostiuchenko was raised in Kiev, Ukraine, where he
attended secondary school from 1980 through 1990. Later, he attended the
Military University of Defense of Russian Federation in Moscow where he
received a master’s degree in linguistics; Kostiuchenko was fluent
in four languages: Ukrainian, Russian, English, and Farsi and could also
communicate in German. Kostiuchenko achieved the rank of captain in the
Ukrainian armed forces where he served from 1995 to 1999, and was a
military intelligence officer who served as a liaison with the Federal
Bureau of Investigation, the Drug Enforcement Administration, and the
Central Intelligence Agency. Kostiuchenko held the very prestigious
position of serving as the adjutant to the general of the Ukrainian army.
Kostiuchenko began his career with the County of Ventura in April 2003. He
initially worked as a program administrator with the Sheriff’s
Office of Emergency Services where he assisted with training and response
plans for the county’s Terrorism Working Group. On July 5, 2007,
Kostiuchenko was hired as a deputy sheriff trainee and began the rigorous
five-month training program at the Sheriff’s Regional Training
Center. Kostiuchenko was a member of Class 2007-2 that began with 25
sheriff’s recruits and graduated 20. Through Kostiuchenko’s
discipline, dedication, and work ethic, he was one of the successful 3%
who made it all the way from the initial application process to
graduation. Kostiuchenko was sworn in as a deputy sheriff on November 29,
2007, and worked in the Detention Services Division until October 2013.
After working in two custody facilities, he was transferred to patrol in
the City of Camarillo where he began patrol training. Kostiuchenko
completed patrol training in April 2014, and worked as a patrol deputy in
Camarillo, proudly serving the residents of that city. Kostiuchenko was an
avid runner who could often be seen running through the streets of
Camarillo as he trained for the Baker to Vegas Challenge Cup Relay. This
event, often referred to as the ultimate foot pursuit, is a difficult
relay race consisting of 120 miles and 20 stages that starts in Baker,
California, and ends in Las Vegas, Nevada. Eugene was a member of the
Sheriff’s Office elite competitive team and would often run the
hardest and longest legs of the race. On October 28, 2014, Kostiuchenko
had completed an early morning traffic stop and was walking back to his
patrol vehicle when he was struck and killed by an intoxicated driver.

The segment of US 101 from South
Seaward Avenue (VEN 28.452) to Vista Del Mar Drive (VEN 29.457) in the
County of Ventura is named the "Ventura County Fire Engineer Ryan
Osler Memorial Highway" (signed as "Ventura County Fire Department Engineer Ryan S.
Osler Memorial Highway". It was named in memory of Fire Engineer
Ryan S. Osler of Santa Clarita, a member of the Ventura County Fire
Department, who lost his life on September 21, 2016, when the water tender
he was riding in rolled over at a roundabout while he was coming into the
City of Lompoc on Route 246. Ryan Osler, who was 38 years of age, was
responding to the Canyon Fire on Vandenberg Air Force Base when, for
unknown reasons, the vehicle hit a curb at the roundabout on Purisima
Road. The driver of the truck suffered minor injuries and was released
from the hospital later that same day. Osler was an 18-year veteran of the
Ventura County Fire Department, who left a wife and two children. His
father had served for 22 years in the same department. Osler was a loving
husband, father, son, and brother to his two sisters. As a young man, a
fast-moving storm caught him and his two sisters off guard as they played
in a cove off Lake Powell. The storm swept away their houseboat and as the
sand swirled furiously, Ryan Osler grabbed a nearby beach bag and wrapped
it around his two little sisters. Osler always put others first and loved
the various aspects of his job. He once helped deliver a baby and on
another occasion told an elderly woman that she would be okay and that
they were there to help. Osler believed that a job wasn’t worth
doing unless you were doing it the right way and at 150 percent. He was
always there to reassure those he served. Osler was the first member of
the Ventura County Fire Department to die in the line of duty in 25 years.

The bicycle-pedestrian path (Class 1 Bicycle path) constructed as part of the project to widen US 101 (US 101
Carpool Lane Improvement Project), from Mobil Pier Road (~ VEN 28.465) to
Bates Road (~ VEN R43.601) in the County of Ventura, is named the "Ralph
Fertig Memorial Bicycle-Pedestrian Path". It was named in memory of
Ralph Fertig, a longtime bicycle advocate in Santa Barbara of such
consistency, durability, and selflessness that his presence achieved an
almost geologic aspect, who passed away on July 18, 2014. Fertig, a
lynch-pin of bicycle activism in the Santa Barbara area and statewide,
raised the profile of bicycling in Santa Barbara and was responsible for
bringing the 1998 ProBike conference to Santa Barbara. Fertig also served
as the Regional Director of the California Association of Bicycling
Organization (CABO) for the Central Coast for many years. Quiet,
unassuming, and absolutely dogged, Fertig made it his mission for more
than 20 years to attend every transportation planning meeting to bear
witness to the need for more space on the roads for bicycles. To an
uncommon extent, Fertig understood the complicated anatomy of
transportation funding; he knew where the money was hidden, what it had
been set aside for, and far better than most, he understood the rules and
regulations guiding the expenditure of those funds. Fertig was respectful,
positive, and persistent and was the first local bicycle advocate to
consistently assess and provide public comment on the needs of the
bicycling community. Named by Assembly Concurrent Resolution (ACR) 58,

The pedestrian undercrossing of US 101 in the
community of La Conchita in the County of Ventura (~ VEN 41.628) is named
the "Peter Douglas Coastal Access Way". It was named in memory of
Peter Douglas, the former Executive Director of the California Coastal
Commission, who passed away during the night on Sunday, April 1, 2012, at
his sister’s home in La Quinta, California at 69 years of age after
a long battle with cancer. Douglas was the CCC’s longest-serving
executive director, a position he held from 1985 to 2011, inclusive. Prior
to working for the commission, he served in the Legislature as an aide to
then-Assembly Member Alan Siertoy (D-Beverly Hills), and as a committee
consultant. During that time he was responsible for the drafting and
passage of Proposition 20 (the Coastal Initiative) in 1972, as well as the
California Coastal Act of 1976 which created the California Coastal
Commission. Over the decades, Douglas’ name has become synonymous
with coastal protection. His accomplishments are too numerous to list, but
he played a part in creating, acquiring, or preserving many coastal parks
and state beaches, campgrounds, trails, and overnight hostels, including
Crystal Cove, Garrapata, Tollowa Dunes, Steep Ravine and Sea West State
Parks, San Onofre and Doheney Beach State Campgrounds, the Monterey Bay
Recreational Trail, the Avila Lighthouse Trail, the Point Buchon Trail,
and many others. Douglas also worked to protect California’s ocean
waters from offshore oil development and other industrial practices.
During his 34-year tenure at the commission, Peter Douglas earned the
love, respect, and loyalty of his staff, and inspired environmental
advocates and stewards statewide and beyond. He will be forever remembered
for his kind heart and unpredictable sense of humor. Douglas was the first
recipient of the national Julius A. Stratton “Champion of the
Coast” award for leadership in coastal management at Coastal Zone
‘95, an international, biennial symposium on coastal zone
management. He provided technical assistance on coastal management issues
to other countries and served on the China-United States panel on
integrated coastal management and was a member of the first National
Oceanic Atmospheric Administration (NOAA) Science Advisory Board and
served on the National Academy of Sciences Committee on Science and Policy
for the Coastal Ocean. In 2008, the Department of Transportation
approached the California Coastal Commission with a plan to improve US 101
in the Counties of Ventura and Santa Barbara. This ambitious proposal
involved adding a carpool lane, bicycle lane, and a pedestrian
undercrossing, and other safety and access improvements. Douglas suggested
changes to the project that involved a major redesign and, when all was
said and done, the department proceeded with his suggestions. Named by
Assembly Concurrent Resolution (ACR) 58, Res. Chapter 153, Statutes of

and boots. Officer O’Connor’s fellow officers called for help
and immediately began cardiopulmonary resuscitation (CPR). He was
transported to a nearby hospital, but succumbed to his injuries. Officer
O’Connor was a good man and a good officer. He was known for his
skill in riding motorcycles and his ability to get into accidents when
driving an automobile. One day, while on patrol, Officer O’Connor
managed to crash his patrol car into the center divider at approximately
75 mph while trying to split traffic. It was named in recognition of

Officer Oswald proudly served a total of 20 years and one month as a
California Highway Patrol Officer. Officer Oswald was killed in the line
of duty on June 27, 2010, in Paso Robles, California, when he was struck
by a vehicle while waiting for a tow truck on the side of the road. He
responded to a report that a vehicle had hit a tree on South River Road in
Paso Robles. After investigating, Officer Oswald determined that no
accident had occurred and that the vehicle was abandoned. He called for a
tow truck and was waiting next to his patrol car, when a passing vehicle
crossed the double yellow lines and struck the patrol car. The force of
the impact pushed the patrol car into him. Officer Oswald was transported
to a local hospital where he later died from his injuries. In his spare
time, Officer Oswald enjoyed reading, photography, making people laugh,
working on his property, and a good cigar from time to time. Above all
else, Officer Oswald enjoyed spending time with his family. Named by
