Post 1964 Signage History
1963 - 1965 Routing (SF Bay Area)
In 1963, Route 117 was defined as the route ran
from "Crystal Springs Road in the City of San Bruno northerly to Route 280
in Daly City." Its definition also noted that " Joint Highway District No.
10 is dissolved in accordance with the provisions of Chapter 20 of Part 1
of Division 16 of the Streets and Highways Code, and all property, assets,
and liabilities of said district are the property of the State."
In 1965, that definition of Route 117 was deleted by Chapter 1372. This
included the portion of Junipero Serra Boulevard south of Serramonte
Boulevard, which did not have the parallel I-280 until the early 1970s.
This segment is built to expressway standards, complete with CalTrans
green signs at intersections, jersey barriers, and even a CalTrans
maintenance station at Junipero Serra and Westborough. This may also have
been what is the current routing of I-280, as in 1967 some maps show Route 280 as continuing along Skyline to Sneath in San Bruno before cutting up
to S San Francisco and Daly City.
A document on the Millbrae Spur Property noted that:
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 new route was located considerable west of the
original route; it no longer divided the Peninsula cities. In the 1960s
the route was again modified, and the proposed Junipero Serra Highway
was absorbed into the Interstate Highway System, which created I-280
connecting San Francisco and San Jose.
Chris Sampang has surmised this might confirm that former Route 117 is
leftover right of way. Scott Parker (SParker) confirmed that on AAroads, noting:

As I-280 functionally supplanted that section of Junipero Serra Blvd.,
it was likely that the present configuration was made to enhance the
local business prospects of the immediate area; it moved from side to
side to connect existing commercial facilities. FYI, the original
supplanted segment of Serra was the original (1964) Route 117; that
designation was deleted ca. 1970 after I-280 was opened to
noted that at Seton Hospital there is an overhead picture of Daly City
from 1955 that shows two grade separations on the Junipero Serra Boulevard
corridor (Route 117), which correspond to current exits on the Serra
Freeway: Alemany Boulevard/John Daly Boulevard and Washington Street.
There are some intriguing difference.
- For Alemany Boulevard, the current southbound-to-southbound flyover
was in place, but current John Daly Boulevard east of this junction (to
Mission Street, former US 101 and current Route 82) was not constructed
at the time. Instead, eastbound John Daly (then an extension of Alemany
Boulevard and part of Route 1) coming from the Westlake area fed
directly into Alemany northbound. It appears that the configuration of
the current northbound Route 1 to northbound Alemany ramp was probably
adjusted in the mid-1960s when the interchange with the Southern Freeway
(current I-280) was built. At that time, John Daly Boulevard was
extended east to current Route 82 (and also taken out of the state
system after Route 1 was placed on a new alignment from Pacifica to
Colma, a result of the 1957 earthquake in Daly City). A flyover was then
constructed for John Daly; thus, the southbound flyover now feeds into a
collector/distributor road for the John Daly Boulevard interchange with
the Route 1 portion of the Junipero Serra Freeway. Note that this
portion of the Serra Freeway was I-280 between the advent of the
interstates and 1968, although it is unclear if it was signed as such.
It has always been part of Route 1 north of John Daly however. Also, the
portion of Alemany Boulevard directly from this interchange up to San
Jose Avenue may have been a pre-freeway routing of LRN 225, which later
became part of the Southern Freeway I-280 route.
- For Washington Street: The 1955 picture shows a diamond interchange at
Washington Street in Daly City. However, this original interchange has
been almost completely removed: the only vestige being the ramp from
Washington to northbound I-280/Route 1. The old southbound ramps to
Washignton seem to correspond to the current Briggs Street near a former
Safeway site (now In-N-Out Burger). The northbound offramp was removed
when this portion of the freeway was upgraded to I-280, and Junipero
Serra Boulevard realigned to cross over I-280. The nearby exit here is
now labeled "Mission Street/Eastmoor Avenue"; northbound, this
interchange is currently tied into the complex for Route 1 and I-280 and
also provides access to the Colma BART station.
1972 - 1986 Routing (San Diego Area)
In 1972, Chapter 1216 recreated Route 117 as "the
international boundary near Borderfield northeasterly to Route 5."
In 1976, Chapter 1354 changed "Borderfield" to "Border Field" and added
"(b) Route 5 near the south end of San Diego Bay to Route 125 near Brown
Field." This was a transfer from Route 75.
In 1986, Chapter 929 renumbered Route 117 as (non-chargable interstate)
Pre 1964 Signage History
The 1964-1965 routing was LRN 237, but was never constructed or signed.
The post-1972 routing was new, although the portion added from Route 75
was approximately LRN 281, although its proposed routing was slighly N of
the current Route 905.
Route 117 was not defined as part of the initial state signage of routes
in 1934. It is unclear what (if any) route was signed as Route 117 between
1934 and 1964.
Pre-1964 Legislative Route
In 1933, Chapter 767 added the route from "Monterey to [LRN 2] near
Salinas" to the highway system. In 1935, this was codified as LRN 117 in
the highway code with that definition, which remained unchanged until the
1963 renumbering. The route ran from Monterey to US 101 near Salinas, and
is present-day Route 68.
Tom Fearer investigated the history of LRN 117, and noted the following:
(Source: Gribblenation Blog (Tom Fearer), "California State Route 68")
- On the 1935 County Highway Map of Monterey County, LRN 117 appears
enter the city along the modern route and likely used Fremont Street to
Meet Route 1, which would have probably been on Del Monte Avenue.
- By 1942, LRN 117 seems to have been pushed back off of Fremont as
Route 1 seems to have assumed the alignment through Monterey. This makes
sense since parts of Fremont Street are signed as Business Route 1.
- By 1961, LRN 117 became signed as Route 68.
- By 1964, LRN 117 is reassigned as Route 68 during the state highway
renumbering. Route 68 remains signed only between Salinas to Monterey.
- By 1967 it appears that the small segment of Route 68 intersecting
Route 1 became a freeway. I'm to understand that the freeway segment
over the Salinas River became a freeway as well the change does not
appear until the 1969 state highway map. The Salinas River freeway
segment appears to have replaced what is now Hilltown Road and Spreckels
Lane. The previous bridge over the Salinas River was a truss design much
like the San Lucas Bridge to the south.
Acronyms and Explanations:
- "LRN" refers to the Pre-1964 Legislative Route Number.
"US" refers to a US Shield signed route.
"I" refers to an Eisenhower Interstate signed route.
"Route" usually indicates a state shield signed route, but said route may be signed as US or I.
- Previous Federal Aid (pre-1992) categories:
Federal Aid Interstate (FAI); Federal Aid Primary (FAP);
Federal Aid Urban (FAU); and Federal Aid Secondary (FAS).
Current Functional Classifications (used for aid purposes):
Principal Arterial (PA); Minor Arterial (MA);
Collector (Col); Rural Minor Collector/Local Road (RMC/LR). Note that ISTEA repealed the previous Federal-Aid System, effective in 1992, and established the functional classification system for all public roads.
