Paper Highways: California State Route 81

California State Route 81 is a never constructed thirty-one-mile State Highway which was located in the Inland Empire area.  California State Route 81 was defined as part of the 1964 State Highway Renumbering over what had been part of Legislative Route Number 276.  California State Route 81 is presently defined as being routed from Interstate 215 east of Riverside to Interstate 15 south of Devore.  Above the blog cover photo depicts the planned California State Route 81 can be seen as it appeared on the 1970 Division of Highways Map.  


The history of California State Route 81

What was to become California State Route 81 entered the State Highway System via 1959 Legislative Chapter 1062 as Legislative Route Number 276.  The original definition of Legislative Route Number 276 was as follows:

"Legislative Route Number 78 (US Route 395) east of Riverside to Legislative Route Number 193 south of Devore."

From the outset Legislative Route Number 276 was part of the Freeway & Expressway System which had also been codified during 1959.  Legislative Route Number 276 first appears on the 1960 Division of Highways Map with no adopted routing.  


As part of the 1964 State Highway Renumbering the Legislative Route Numbers were dropped.  Legislative Route Number 276 subsequently became California State Route 81.  The original definition of California State Route 81 was as follows:

"Route 395 east of Riverside to Route 31 south of Devore."

California State Route 81 appears for the first time on the 1964 Division of Highways Map.  

California State Route 81 never was referenced in the California Highways & Public Works before the publication ended during 1967.  California State Route 81 never at any point has had a formally adopted routing.  

1969 Legislative Chapter 294 changed the southern terminus of California State Route 81 to "Route 15" which reflected the change of alignment of Interstate 15 over what had been US Route 395.  The new southern terminus of California State Route 81 at Interstate 15 appears on the 1970 Division of Highways Map.  


1976 Legislative Chapter 1354 changed the southern terminus of California State Route 81 to "Route 194" which reflected the change of alignment of Interstate 15E over what had been Interstate 15.  The designation of California State Route 194 was utilized as a loophole to get around the numbering duplication of Interstate 15 and prohibition of suffixed routes.  Interstate 15 had been shifted to what had previously been designated as California State Route 31.  The new terminus points of California State Route 81 appear on the 1977 Caltrans Map.  


1982 Legislative Chapter 681 changed the southern terminus of California State Route 81 to "Route 215" which reflected the designation of Interstate 215 over what had been Interstate 15E/California State Route 194.  The new southern terminus of California State Route 81 at Interstate 215 appears on the 1986 Division of Highways Map.

The Central Freeway of San Francisco (US Route 101)

The Central Freeway is a 1.2-mile elevated limited access corridor in the city of San Francisco.  As presently configured the Central Freeway connects from the end of the Bayshore Freeway to Market Street.  The Central Freeway carries the mainline of northbound US Route 101 from the Bayshore Freeway to Mission Street. The Central Freeway has origins with the establishment of Legislative Route Number 223 and is heavily tied to the history of the once proposed Panhandle Freeway.  The Central Freeway between the Bayshore Freeway and Mission Street was completed during 1955.  The corridor was extended to a one-way couplet located at Turk Street and Golden Gate Avenue in 1959 which served to connect US Route 101 to Van Ness Avenue.  The Central Freeway was damaged by the 1989 Loma Prieta Earthquake and has since been truncated to Market Street.   The Central Freeway as pictured on the blog cover was featured in the May/June 1959 California Highways & Public Works.  The scan below is fro

The Bayshore Freeway (US Route 101)

The Bayshore Freeway is a 56.4-mile component of US Route 101 located in the San Francisco Bay Area.  The Bayshore Freeway connects the southern extent of San Jose to the Central Freeway in the city of San Francisco.  The corridor was originally developed as the Bayshore Highway between 1923 and 1937.  The Bayshore Highway would serve briefly as mainline US Route 101 before being reassigned as US Route 101 Bypass in 1938.  Conceptually the designs for the Bayshore Freeway originated in 1940 but construction would be delayed until 1947.  The Bayshore Freeway was completed by 1962 and became mainline US Route 101 during June 1963.   Part 1; the history of the Bayshore Freeway Prior the creation of the Bayshore Highway corridor the most commonly used highway between San Jose and San Francisco was El Camino Real (alternatively known as Peninsula Highway).  The  American El Camino Real  began as an early example of a signed as an Auto Trail starting in 1906.  The era of State Highway Mainte

Former US Route 101 and California State Route 41 through Paso Robles

Paso Robles is a city located on the Salinas River of San Luis Obispo County, California.  As originally configured the surface alignments of US Route 101 and California State Route 41 converged in downtown Paso Robles.  US Route 101 originally was aligned through Paso Robles via Spring Street.  California State Route 41 entered the City of Paso Robles via Union Road and 13th Street where it intersected US Route 101 at Spring Street.  US Route 101 and California State Route 41 departed Paso Robles southbound via a multiplex which split near Templeton.   Pictured above is the cover of the September/October 1957 California Highways & Public Works which features construction of the Paso Robles Bypass.  Pictured below is the 1935 Division of Highways Map of San Luis Obispo County which depicts US Route 101 and California State Route 41 intersecting in downtown Paso Robles.   Part 1; the history of US Route 101 and California State Route 41 in Paso Robles Paso Robles ("Pass of the
