California Highways

From Route 49 near Coloma to Marshall's Monument.

This route is unchanged from its 1963 definition.

This route was LRN 92, defined in 1933. It was not signed. This route exists in the State Historic Park.

Route 153 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 153 between 1934 and 1964.

This route has only one sign, at its start. Below the sign is another sign noting this is California's Shortest State Highway (although it really isn't; another highway, Route 283, has that honor).

Overall statistics for Route 153:

• Total Length (1995): 0.5 miles
• Average Daily Traffic (1992): 100 to 2,250
• Milage Classification: Rural: 0.5; Sm. Urban: 0; Urbanized: 0.
• Previous Federal Aid Milage: None.
• Functional Classification: Collector: 0.1 mi; Rural Minor Collector/Local Road: 0.4 mi.
• Counties Traversed: El Dorado.

In 1933, Chapter 767 defined the route from "Hueneme to Montalvo-San Fernando Road near Somis via Oxnard and Camarillo" to be a state highway. In 1935, this route was added to the highway code as LRN 153, with the following definition:

"Hueneme to [LRN 9] near Somis via Oxnard and Camarillo"

In 1959, Chapter 1062 changed the definition to delete the specific routing: "…near Somis via Oxnard and Camarillo".

This route is present-day Route 34.

From Route 101 near Zaca to Route 101 near Santa Barbara via San Marcos Pass.

This routing is unchanged from its 1963 definition.

This route was originally signed as part of Route 150; it was resigned as part of Route 154 sometime before 1963. See Route 150 for some details of its history as Route 150. According to a photo supplied by Joel Windmiller, at some time between 1957 and 1964 it ran through Lompoc proper, cosigned with Route 1, along what is currently Route 246. It was LRN 80, defined in 1931.

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures on or near this route:

• High Priority Project #184: Reconstruct segments of Hollister Avenue between San Antonio Road and Route 154 in Santa Barbara County. Hollister Avenue is a main feeder street for Route 154, runs parallel to US 101, and may have been a former surface street routing of US 101. $2,000,000.

This has historically been named the "San Marcos Pass" Road from Route 101 near Santa Barbara to Los Olivos.

Historically, this route has also been named "El Camino Cielo" (The Road to the Sky).

Designated in its entirety as the "Chumash Highway". This segment was named in honor of the Chumas Indian tribe. In prehistoric times, the Chumash territory encompassed some 7,000 square miles, and today, this same region in southern central California takes in five counties, including Santa Barbara, Ventura, San Luis Obispo, Los Angeles, and Kern. While some place names in this geographic region reflect their Chumash language origins, the trails and routes that connected them remain unrecognized as the forerunners of today's highways. Route 154 follows an elaborate Chumash trail network, which linked several hundred early Chumash villages and towns, seasonal encampments, rock art sites, shrines, gathering places, and water sources, and these trails were vital to sustaining cultural longevity for over 8,000 years in this region as they formed the foundation for economic and social exchange among the Chumash. In historic times, routes through the Chumash territory were first recorded in the diaries of the Gaspar de Portola Expedition in 1769, in which it is noted that in many instances Chumash Indians led members of the expedition from one village to another, showing them the trails. Many notable works subsequently validate the location of the Chumash trail system, including along present-day Route 154. Numerous archaeological sites along Route 154 further support the historical significance of the area and the trails to the Chumash. Named by Assembly Concurrent Resolution (ACR) 75, Resolution Chapter 149, on October 2, 2007.

In 1933, Chapter 767 defined the routes from "[LRN 2] near El Rio to Montalvo-San Fernando Road near Saticoy" and from "The Montalvo-San Fernando Road near Saticoy to [LRN 79]" as part of the state highway system. In 1935, LRN 154 was added to the highway code with the following routing:

1. [LRN 2] near El Rio to [LRN 9] near Saticoy
2. [LRN 9] near Saticoy to [LRN 79]

In 1951, Chapter 1562 added the segment from LRN 60 to LRN 2 as a new segment (a): "(a) The junction of [LRN 60] and Saviers Road in Ventura County, along the route of said road to [LRN 2] near El Rio."

In 1957, Chapter 1911 removed the portion of the routing north of [LRN 9] (Route 118), simplified the origin, and eliminated the discontinity: "[LRN 60] near El Rio to [LRN 9] near Saticoy."

This route (Route 1 to Route 118) is present-day Route 232.

From Route 99 near Delano to Route 178 near Isabella via Glennville.

In 1963, Chapter 385 ("Great Renumbering") defined this route as "Route 99 near Bakersfield to Route 178 near Isabella via Glennville.", although Chapter 1698 quickly changed "Route 99" to "Route 204", reflecting the rerouting of Route 99 onto the freeway routing.

In 1965, Chapter 1372 realigned the route and transferred a segment from Route 211, giving "Route 99 near Delano to Route 178 near Isabella via Glennville."

As defined on July 1, 1964, Route 155 began at Route 204 near Bakersfield. In 1965, the portion from Route 204 to Woody was deleted, and the portion from Route 99 to Woody added.

The original definition of this route was all of the original LRN 142, defined in 1933. See LRN 142 for the details of this version of the route. After 1965, a portion of LRN 136 (between Route 99 and the Famoso-Porterville Highway) was added. The remainder of this route (a direct route from the Famoso-Porterville Highway to Woody) was not defined before 1963.

Route 155 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 155 between 1934 and 1964.

The segment of this route from Route 58 to Kernville via the Caliente-Bodfish Road) was historically named the "Lions Trail".

Note: There are extremely steep grades on the east end of this highway.

Overall statistics for Route 155:

• Total Length (1995): 63 miles
• Average Daily Traffic (1992): 160 to 8,200
• Milage Classification: Rural: 62; Sm. Urban: 1; Urbanized: 0.

In 1933, Chapter 767 added the routes from "[LRN 60] near Aliso Canyon to [LRN 2] near Triunfo" and "[LRN 2] near Newbury Park to [LRN 79] near Fillmore" to the state highway system. In 1935, these routes were added to the highway code as LRN 155, with the following definition:

1. [LRN 60] near Aliso Canyon to [LRN 2] near Triunfo
2. [LRN 2] near Newbury Park to [LRN 79] near Fillmore

This routing remained unchanged until 1963. It was all signed as part of Route 23, and included portions of Decker Canyon Road and Westlake Road.

1. From Route 1 near Castroville to Route 101 near Prunedale.

   
   

   	This segment is unchanged from its 1963 definition.
   	This entire routing was LRN 22. This segment was defined in 1933. It was signed as Route 156 by 1963, but was not part of the original 1934 state signage of routes.
   	Constructed to freeway standards from Route 1 near Castrovile to Castroville Blvd. Until the early 1980s, Route 1 entered Castroville from the south via Route 156 eastbound (the current freeway), then exited at the diamond interchange for Merritt Street and continued northwest via Merritt. However, by the mid-1980s, the current Castroville bypass was constructed; as a consequence, the portion of freeway on Route 1 between Merritt Street and the bypass became an extension of Route 156, and Merritt Street became part of Route 183. The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures on or near this route: High Priority Project #3804: Widening of Route 156 in Monterey County between Castroville and US 101. $5,000,000.

   
   

2. From Route 101 to Route 152 passing near San Juan Bautista and Hollister.

   
   

   	In 1963, this segment was defined as "(b) Route 101 near The Rocks to Route 152 via San Juan Bautista and Hollister." In 1968, Chapter 282 clarified the routing as "(b) Route 101 near The Rocks to Route 152 via passing near San Juan Bautista and Hollister."
   	This entire routing was LRN 22. The original portion of the route was defined in 1909 and ran from San Juan Bautista to Hollister. In 1919, the portion from Hollister to Route 152 was defined, and in 1933, the remainder of the route (between Castroville and San Juan Bautista) was added. It was signed as Route 156 by 1963, but was not part of the original 1934 state signage of routes.
   	In 1997, a bypass was opened from the intersection of Route 156 and San Felipe Road angling bypassing the city of Hollister to point west of town near Union Road. This is a two-lane bypass built to expressway standards. The old routing through town is still signed as Route 156 and Route 25 for some of it. There are plans to widen this to four lanes; the EIR was completed in September 2002, per CTC September 2002 Agenda. Constructed to freeway standards from US 101 near San Juan Bautista to San Juan Road. 2007 CMIA. Two projects on Route 156 in Monterey County were submitted to the Corridor Mobility Improvement Account for funding. These projects were a 4 lane expressway, Alameda to Union-Mitchell ($37,987K requested) and the Route 156 Corridor west phase 1 ($166,700K requested) . Neither was recommended for funding. In his 2006 Strategic Growth Plan, Governor Schwartzenegger proposed converting two major conventional roadway segments to four-lane expressway. Projects have major safety and mobility benefits for travel from the Bay Area to the Monterey Peninsula and from the Central Valley to US 101. In November 2007, the CTC reviewed a draft EIR for a project to construct roadway improvements that include widening, from two lanes to four lanes, a portion of Route 156 near Hollister. The project is not fully funded. The project is programmed in the 2006 State Transportation Improvement Program for project development and right-of-way for $22,203,000. The total cost of the project is estimated to be $78,300,000, capital and support. This project should be ready for construction in Fiscal Year 2009-10, depending on the availability of funds. The alternatives are basically (a) whether the roadway is divided or conventional, and (b) whether there are frontage roads, and on which sides of the highway. The project would be between The Alameda (PM 3.0) and San Juan Road (PM 8.2). According to vta.org, there are currently plans to build a flyover ramp intersection with Route 156. Estimated completion date is 2008. The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures on or near this route: High Priority Project #1759: Improvements to the Route 152/Route 156 Intersection. $800,000. High Priority Project #1793: Reconfigure intersection at Route152 and Route 156 in Santa Clara County. $11,120,000.
   	Bridge 43-0044, the San Benito River Bridge, in San Benito County is named the "Ed Hanna Memorial Bridge". It was named by Senate Concurrent Resolution 22, Chapter 65 in 1997. Ed Hanna was a long time San Benito County employee, having worked in the 1940's as county surveyor and later as County Engineer and Road Commissioner.
   	The old routing throuh the city of Hollister is signed as Business Route 156.
   	This route is part of the De Anza National Historic Trail.

In 1933, Chapter 767 defined the route from "[LRN 60] near Topanga Beach to Montalvo-San Fernando Road near Chatsworth" as a state highway. In 1935, this route was added to the highway code as LRN 156, with the definition:

"[LRN 60] near Topanga Beach to [LRN 9] near Chatsworth"

In 1959, Chapter 1062 clarified the definition to be: "[LRN 60] near Topanga Beach but north of the intersection of Sunset Boulevard and [LRN 60] to [LRN 9] at or near Chatsworth"

This is present-day Route 27 (Topanga Canyon). At one time, it was proposed for the Reseda Freeway.

No current routing.

In 1963, Route 157 was defined as "Route 805 near San Diego and south of Route 94 to Route 125 near Sweetwater Reservoir.".

In 1972, Chapter 1216 relaxed the routing: "Route 805 near San Diego and south of Route 94 to Route 125 near Sweetwater Reservoir."

In 1994, the routing (from Route 805 near Ocean View Boulevard near San Diego, through the Paradise Hills to Route 125 near Sweetwater Reservoir) was deleted per AB 3132, Chapter 1220. The route was added to the state highway system in 1959. A routing was adopted in 1962, but it was rescinded locally by SANDAG (San Diego Association of Governments, the regional planning agency) in 1974, and deleted from the state highway system 20 years later. The right-of-way purchased for the eastern portion of the route was sold in the mid-1970s. Together with Route 252 (the Southcrest or El Toyon Freeway) and I-5, the route would have provided direct access from East San Diego County to downtown.

This was proposed LRN 285, defined in 1959. It was never signed.

Route 157 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 157 between 1934 and 1964.

This route would have been named the San Miguel Freeway.

Originally to have been freeway; later deleted from SHC 253.1.

In 1933, Chapter 767 defined the route from "[LRN 4] near Tunnel Station to [LRN 9] near San Fernando" as a state highway. It was added to the highway code in 1935 as LRN 157 with that routing. This was the route from US 99 (I-5) to Route 118, and was the eventual routing of Route 210 between I-5 and Route 118.

• Mike Ballard's Virtual Tour of CA 118 and LRN 157 to Pasadena

From Route 395 near June Lake to Route 395 near Rush Creek, via the vicinity of June Lake, Silver Lake and Grant Lake.

In 1963, this was defined as the route from "Route 395 near Rush Creek to Route 395 via June Lake."

In 1965, Chapter 1371 clarified the routing: "Route 395 near Rush Creek June Lake to Route 395 near Rush Creek, via the vicinity of June Lake, Silver Lake and Grant Lake".

This was LRN 111, defined in 1933. It appears not to have been signed before 1963, although the route itself dates back to 1935.

Route 158 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 158 between 1934 and 1964.

[SHC 263.1] Entire route.

Overall statistics for Route 158:

• Total Length (1995): 16 miles
• Average Daily Traffic (1992): 610 to 1,850
• Milage Classification: Rural: 16; Sm. Urban: 0; Urbanized: 0.
• Previous Federal Aid Milage: FAS: 16 mi.
• Functional Classification: Collector: 16 mi.
• Counties Traversed: Mono.

In 1933, Chapter 767 defined the route from "[LRN 4] near San Fernando to [LRN 60] near Mines Field" as part of the highway system. In 1935, this was added to the highway code as LRN 158 with that routing.

In the 1947 1st ex. sess., Chapter 11 rewrote the route to be:

1. (a) [LRN 4] near San Fernando to [LRN 60] near Mines Field Los Angeles Airport
2. (b) [LRN 60] near Los Angeles Airport to a point on [LRN 167] near Signal Hill

This showed the growing planning for the San Diego Freeway, which now ran as far as the Long Beach Freeway.

In 1951, Chapter 1562 combined the segments and extended the route from the Long Beach Freeway to the El Toro Y: "[LRN 4] near San Fernando to [LRN 2] in the vicinity of El Toro; provided, however, that Section 600 of this code shall be applicable to that portion of said route southerly of [LRN 167] near Signal Hill the same as if said portion had been added by the Collier-Burns Act of 1947, and the Department of Public Works shall not be required to maintain any portion of said route until the same has been laid out and constructed as a state highway"

In 1955, Chapter 1488 removed the language relating to section 600 (actually, it just made that language a general condition as Section 2109 of the code).

LRN 158 is present-day I-405; before the freeway was constructed, this LRN also applied to pre-1963 Route 7 between the US 99/US 6 junction and Route 107. The original route was along Sepulveda to the intersection with LRN 60 (Lincoln Blvd).

No current routing.

As defined in 1963, Route 159 consisted of two parts:

1. From Route 5 near the Los Angeles River to Route 134

2. From Route 134 to Route 210 near La Cañada

In 1965, Chapter 1372 deleted (a) and added a condition: "This route shall cease to be a state highway when Route 210 freeway is completed from Route 134 to Linda Vista Avenue and the commission relinquishes that portion of present Route 210 from Route 134 to Linda Vista Avenue."

In 1992, part (2) was deleted per AB 3090, Chapter 1243. The route had been relinquished on 7/14/1989.

Part (1) of the 1964 Route 159 was Figueroa Blvd between I-5 and Route 134, and was originally signed as Route 11 and US 66 (and later, as US 66A). Part 2 was Linda Vista Avenue between Route 134 and eventual I-210 (likely, it ended at Foothill Blvd before). This was signed as Route 11. Both segments were part of LRN 165, defined in 1933.

One 1939 map shows Route 159 as being signed along the route along Lankershim Blvd between Route 134 (Alameda Avenue before the freeway) and US 99 (San Fernando Road). This appears to coincide with Lankershim's designation as LRN 159.

Former part (1) of this route is signed as part of "Historic Highway Route 66", designated by Assembly Concurrent Resolution 6, Chapter 52, in 1991.

The former part (1) of this route (Figueroa) was part of the "Arrowhead Trail (Ocean to Ocean Trail)". It was named by Resolution Chapter 369 in 1925.

The former part (1) of this route (Figueroa) was part of the "National Old Trails Road".

The former part (1) of this route (Figueroa) appears to have been part of the "National Park to Park Highway", and the "Pikes Peak Ocean to Ocean Highway".

In 1933, the route from "Lankershim Blvd from [LRN 2] near Universal City to [LRN 4]" was defined as a state highway. In 1935, it was added to the highway code as LRN 159 with that routing.

In 1951, Chapter 1562 truncated and clarified the definition to be "[LRN 2] near Vineland Ave to [LRN 4] near Tujunga Wash"

In 1957, Chapter 1911 changed the origin to "[LRN 2] near Riverside Drive to …"

This route was Lankershim Blvd between US 101 and San Fernando Road. Some maps show it signed as Route 159, but that is clearly an error confusing the LRN with the signed rout number. The LRN was also applied to the present-day Route 170 freeway routing. Lankershim Boulevard was named for the town of Lankershim (first called Toluca, now North Hollywood) and its founding family. Isaac B. Lankershim grew wheat in a wide swath of the Valley.

From Route 4 near Antioch to the southern city limits of Sacramento.

The relinquished former portion of Route 160 within the City of Sacramento is not a state highway and is not eligible for adoption as a state highway.

In 1963, Route 160 was defined as "Route 84 near Rio Vista to Route 80 near North Sacramento via Sacramento."

In 1968, Chapter 282 changed the terminus of the route: "… to Route 80 near North Sacramento via Sacramento."

In 1976, Chapter 1354 changed "Route 84" to "Route 12".

In 1981, Chapter 292 extended the route and corrected the references to reflect the change of I-80's routing: "(a) Route 4 near Antioch to Route 12 near Rio Vista. (b) Route 12 near Rio Vista to Route 80 near North Sacramento Route 51 via Sacramento." This change reflected the transfer of the portion from Route 4 to Route 12 from Route 84.

In 1984, Chapter 409 recombined the segments, giving "Route 4 near Antioch to Route 51 in Sacramento." Note that although until 1981 Route 160 was legislatively defined to start at Route 12 in Rio Vista, in actuality, Route 160 has always begun (signed) at Route 4 in Antioch. This means that while the Antioch Bridge may have been legislatively Route 84 from 1964-1981, it always was part of signed Route 160.

In 1999, Senate Bill 802, Chapter 172, authorized the California Transportation Commission to reliquish any portion of Route 160 in Sacramento County between PM 35.0 and PM 47.0 (i.e., the surface street portion) to the containing city upon request. As of November 2001, this segment (from the American River Bridge to 3/4 mile north of the town of Freeport) had been decomissioned, and according to reports in February 2002, officially relinquished. The state removed the shield on the overhead signs on US 50 in 2004.

In 2003, Assembly Bill 1717, Chapter 525, officially truncated the route to "(a) Route 160 is from Route 4 near Antioch to the southern city limits of Sacramento. (b) The relinquished former portion of Route 160 within the City of Sacramento is not a state highway and is not eligible for adoption under Section 81."

The North Sacramento Freeway has an interesting quirk: Unlike all other freeways in California, there are no shields on the green sign gantries, only control cities (Downtown Sacramento and Roseville/Reno). According to Joel Windmiller, the signs were placed in the mid-1960s, in the midst of the Great Renumbering when US 40 was removed from this route; however, CalTrans was not sure what route would eventually assimiliate the North Sacramento Freeway at the time (now Route 160).

The portion of thie route from Antioch to Broadway in Sacramento, via Freeport Boulevard and River Road was LRN 11, defined in 1933, and was originally signed as part of Route 24.

The portion from Broadway west from Freeport to 16th: was LRN 4, and was signed as Route 24, US 50/US 99 (to 1954), and US 99W (1954-1964). The portion from 16th Street in Sacramento north from Broadway to N Street, Capitol Avenue was LRN 4 and was signed as US 50/US 99 (to 1954), and US 99W (1954-1964). The remainder of the route was LRN 3 (defined in 1909), and was signed as follows: the segment from 15th/16th Street north of Capitol Avenue to the 16th Street Bridge was signed as US 40 (to 1964) and US 99E (to 1954); the segment from 12th Street and F Street to 15th Street was signed as US 40 (1950s-1964); and the segment from the 16th Street Bridge and North Sacramento Freeway ws signed as US 40 (to 1964) and US 99E (1946-1954).

A 1939 map shows Route 160 being signed along Highland Blvd between Cahuenga Blvd and Santa Monica Blvd in Los Angeles. This route was LRN 160.

Route 160 is constructed to freeway standards from Route 4 near Antioch to the Antioch Toll Booth, and from Downtown Sacramento to Business Route 80 near Cal Expo.There are "END 160" signs at each crossing of the Sacramento City Limits.

In April 1999, the city of Sacramento begin a study whether it should take over control of Route 160 from the state. The city wanted better access, and CalTrans was unwilling to add additional off ramps. This was expected to lead to the replacement of the bridges at Royal Oaks Dr. and Canterbury Rd with ground-level intersections. In February 2001, the city of Sacramento and Caltrans reached an agreement to relinquish a portion of Route 160 to the city. In particular, the portion from Stonecrest Ave. to the south abutment of the American River Bridge, where the freeway splits into 12th and 16th Sts, was to be relinquished. Stonecrest Ave. is the southern edge city of Sacramento (it's the road running parallel to the PG&E transmission line that passes over I-5 just south of Pocket Rd. next to the GTE/Verizon complex). Note that this excludes the American River Bridge; this be because the city believed the bridge to be falling apart. There are actually two bridges; the southbound bridge was built in 1921 and the northbound bridge in 1967.

At 16th and P Street, a very old BGS is present, pointing the way to San Francisco and Reno. This may date back to the days when this portion of Route 160 was the junction of Route 24 and US 40. The greenout on those signs that covers up the number 40; it's right next to the arrows. At one point, Route 160 and US 40 were cosigned.

According to the Sacramento Bee, plans are in the works to rebuild the intersection of Route 160, Sproule Avenue, Richards Blvd, 12th Street and 16th Street near downtown Sacramento. The problem is that one can't get from Richards Boulevard eastbound onto northbound Route 160, nor from northbound 16th Street to Richards Boulevard. The city of Sacramento is planning to construct a $4.8 million intersection there that will integrate a light-rail line through the intersection. The project should be complete in 2008.

A small portion of this route is designated as part of "Historic US Highway 99" by Assembly Concurrent Resolution 19, Chapter 73, in 1993.

The portion of this route that is former US 99 is, in local usage, called the "East Side Highway".

The portion of this route between Route 4 and Route 50 is historically part of "El Camino Sierra" (Road to the Mountains).

The portion of this route from roughly Del Paso Blvd and Route 51 (BR 80) (i.e., former US 40) was named the "North Sacramento Freeway". Sacramento refers to the City of Sacramento CA, which is based off of the name of the main river in the city. The Spanish name, "Holy Sacrament," was applied to the Feather River in 1808; it was later assumed that the lower Sacramento was the same stream. In 1817 the two main rivers of the valley were recorded as Sacramento and San Joaquin rivers, but the course of the former was not identified with the name until the 1830s. The city was laid out in 1848-1849 and named after the river by John A. Sutter, Jr., and Sam Brannan. The county, one of the original 27, was named in 1850.

Bridge 28-009, the Antioch Bridge near Antioch is named the "Senator John A. Nejedly Bridge". It was built in 1979, and was named by Assembly Concurrent Resolution 146, Chapter 140 in 1978. California State Senator John A. Nejedly authored SB 25, enacted as Chapter 765 of the Statutes of 1972, to authorize the design and construction of the new Antioch Bridge. The original bridge was built in 1926.

HOV lanes exist on the Antioch Bridge. They require three or more occupants (two occupants for two-seater vehicles), and are in operation weekdays during the following hours: 5:00-10:00am, 3:00-6:00pm.

In 1933, Chapter 767 defined the route "Highland Avenue, Los Angeles from Cahuenga Blvd to Santa Monica Blvd" as a state highway. In 1935, this was added to the highway code as LRN 160 with this routing.

In 1949, Chapters 909 and 1467 clarified the routing to be: "Highland Avenue, Los Angeles from Cahuenga Blvd [LRN 2] to Santa Monica Blvd [LRN 162]"

In 1953, Chapter 1253 simplified the definition to eliminate the specific routing: "Highland Avenue, Los Angeles from [LRN 2] to [LRN 162] in the Hollywood Area, Los Angeles"

In 1959, Chapter 1062 clarified and extended the routing: "[LRN 158] near Inglewood to [LRN 2] in Los Angeles to [LRN 162] in the Hollywood Area, Los Angeles"

This route ran from the future I-405 near Inglewood to US 101 in Los Angeles. This was a freeway that was never constructed; the "Laurel Canyon" freeway, Route 170, between the San Fernando Valley and Inglewood. It is the reason that the offramp from I-405 NB at La Cienega is constructed as it is; it is also the reason for the "La Cienega Expressway" between Centinela (former Route 107) and Rodeo. There are portions that still indicate the Route 170 presence. The only designated portion was along Highland between LRN 2 and Santa Monica Blvd.
