Guadalupe Canyon Parkway

Guadalupe Canyon Parkway is a four-mile mountainous expressway located in the San Mateo County, California. Guadalupe Canyon Parkway connects Market Street in Daly City east to Bayshore Boulevard (former US Route 101) via San Bruno Mountain. The corridor was completed as a partially limited access road in 1968 and is mostly known for being part of the famous chase scene in the movie Bullitt.

Part 1; the history of Guadalupe Canyon Parkway

San Bruno Mountain is a fault block horst which extends from northern San Mateo County into the city of San Francisco.  San Bruno Mountain has a peak elevation of 1,319 feet above sea leave but carries a prominence of 1,114 feet. 

During the 1840s Bruno de Heceta coined the name "Sierra de San Bruno" to honor his patron saint.  When California became an American state, the name was retained and would be anglicized to "San Bruno Mountain" by the United States Geological Survey.  San Bruno Mountain would become a popular location for cemeteries during the California Gold Rush.  

The city and county of San Francisco would begin to resist expansions of cemeteries in the early 20th century.  This led to the establishment of Colma as a necropolis on the southwest corner of San Bruno Mountain in San Mateo County.  Colman would incorporate as "Lawndale" during August 1924 but would revert to the original name during November 1941.  

A primitive ranching road can be seen crossing San Bruno Mountain from Brisbane west towards Daly City on the 1935 Division of Highways Map.  

The ranching road over the northern extent of San Bruno Mountain can be seen in detail on the 1939 United States Geological Survey Map of San Mateo.  The road can be seen originating in Brisbane in Guadalupe Valley at Bayshore Boulevard (then US Route 101 Bypass).  The opposite end is shown to terminate near what is now Hill Boulevard in Daly City.  

Radio Road can be seen atop San Bruno Mountain on the 1956 United States Geological Survey Map of South San Francisco.  Towers for KQED, KNBC-FM and KRON-TV can be seen at the end of Radio Road at the peak of San Bruno Mountain.  A spur of Radio Road is seen connecting to a military installation near Colma.  The military installation was constructed between 1954-1956 as a control station for the Nike anti-aircraft defense systems of Fort Funston and Milagra Ridge.  

In 1965 Westbay Community Associates announced planned to level 27 acres of San Bruno Mountain.  The earth removed from San Bruno Mountain was intended to be repurposed as landfill at Sierra Point.  The excavated saddle was planned to be developed as several new neighborhood.  Guadalupe Canyon Parkway was constructed during 1968 as partially limited access expressway which would serve the planned neighborhoods on San Bruno Mountain.  

Guadalupe Canyon Parkway was famously used during the filming of the 1968 movie Bullitt.  A mostly then two-lane Guadalupe Canyon Parkway can be seen between 6:45-10:00 as detective Frank Bullitt (played by Steve McQueen) purses a 440ci Magnum V8 1968 Dodge Charger driven by hitmen in his 390ci V8 1968 Ford Mustang GT Fastback.  

During the late 1960s and early 1970s local opposition contributed to real estate development on San Bruno Mountain ceasing.  In 1978 San Mateo County purchased 1,100 acres of San Bruno Mountain which was followed by the State purchasing 256 acres in 1980.  Much of these land parcels now comprise San Bruno Mountain State & County Park.  The older roadway over San Bruno Mountain has since been repurposed as part of the Old Ranch Road Trail and Old Guadalup Trail.  

The State would purchase an additional 83 acres of San Bruno Mountain in 1989 to establish San Bruno Mountain Ecological Reserve.

Part 2; a drive on Guadalupe Canyon Parkway

Guadalupe Canyon Parkway can be reached from Interstate 280 in Daly City following the Sullivan Avenue exit and Market Street east.  Guadalupe Canyon Parkway begins as eastbound Market Street approaches the Daly City limit near Price Street.

Guadalupe Canyon Parkway climbs over the top of San Bruno Mountain and enters the city of Brisbane approaching Carter Street.  

Guadalupe Canyon Parkway descends from Carter Street and terminates at Bayshore Boulevard.

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

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

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
