Del Puerto Canyon Road


Del Puerto Canyon Road is a twenty-four-mile highway which connects Patterson in Stanislaus County west to San Antonio Valley in Santa Clara County.  From Patterson sixteen miles west to Frank Raines Park the grade of Del Puerto Canyon Road was built atop the grade of the Patterson & Western Railroad.  Said line had been completed in 1916 during World War I to the magnesite mine of Jones and was abandoned by 1920.  Stanislaus County and Santa Clara County later facilitated repurposing the railroad grade into a public highway to San Antonio Valley.  The completed Del Puerto Canyon Road would open to traffic during 1942.  




Part 1; the history of Del Puerto Canyon Road

What is now Del Puerto Canyon Road from Patterson west to Frank Raines Park was originally constructed as the grade of the Patterson & Western Railroad.  Said line was constructed as narrow gauge in 1916 from the Southern Pacific Railroad West Side Line in downtown Patterson to the magnesite mine known as Jones.  

The Patterson & Western Railroad began operations on September 20, 1916.  The western terminus of the line connecting to a 3,000-foot-long tramway to the site of the Jones mine.  Magnesite was considered an essential metal during World War I which spurred the development of the Jones mine.  Quicksilver and manganese chrome was also mined at Jones.  

The Patterson & Western Railroad can be seen on the 1919 United States Geological Survey map of Orestimba.  


The Patterson & Western Railroad shuttered operations on August 14, 1920.  The right-of-way occupied by the line was subsequently abandoned to Stanislaus County.  Stanislaus County along with Santa Clara County commissioned a Depression relief program which would repurpose the railroad grade as part of a highway to San Antonio Valley.  The first vehicles to travel from Patterson to San Jose via the completed Del Puerto Canyon Road crossed the Diablo Range in 1942.

Del Puerto Canyon Road can be seen on the 1947 United States Geological Survey map of San Jose. 


Currently California State Route 130 has an eastern terminus at Mount Hamilton in Santa Clara County.  The highway has an unconstructed and unadopted legislative extension which terminates in Patterson.  For unclear reasons Santa Clara County signs California State Route 130 east from the official terminus at Mount Hamilton to the Stanislaus County line via San Antonio Valley Road and Del Puerto Canyon Road.  




Part 2; a drive on Del Puerto Canyon Road

The westbound beginning of Del Puerto Canyon Road can be found a short distance west of Interstate 5 in Patterson via Diablo Grande Parkway.  Traffic is advised that Frank Raines Parkway is sixteen miles away as westbound Del Puerto Canyon Road begins. 






Del Puerto Canyon Road west to Frank Raines Park is mostly aligned atop the grade of the Patterson & Western Railroad.  The roadway is extremely curvy but offers numerous scenic views the slopes of Del Puerto Canyon.  The ruins of a railroad bridge over Del Puerto Creek can be found in the overgrowth a short distance east of Frank Raines Park.  



























































Del Puerto Canyon Road west from Frank Raines Park ascends further into the Diablo Range and enters Santa Clara County.  























Westbound Del Puerto Canyon Roads terminates at fork which serves as the beginning of San Antonio Valley Road and Mines Road.  Traffic wishing to follow California State Route 130 is directed to follow San Antonio Valley Road.

Morgan Territory Road

Morgan Territory Road is an approximately 14.7-mile-long roadway mostly located in the Diablo Range of Contra Costa County, California.  The roadway is named after settler Jerimah Morgan who established a ranch in the Diablo Range in 1857.  Morgan Territory Road was one of several facilities constructed during the Gold Rush era to serve the ranch holdings.   The East Bay Regional Park District would acquire 930 acres of Morgan Territory in 1975 in an effort to establish a preserve east of Mount Diablo. The preserve has since been expanded to 5,324 acres. The preserve functionally stunts the development along roadway allowing it to remain surprisingly primitive in a major urban area. Part 1; the history of Morgan Territory Road During the period of early period of American Statehood much of the Diablo Range of Contra Costa County was sparsely developed.   Jerimah Morgan acquired 2,000 acres of land east of Mount Diablo in 1856 and established a ranch in 1857.

The combined Interstate 210/California State Route 210 corridor of the Foothill Freeway is approximately 85.31-miles.  The Interstate 210/California State Route 210 corridor begins at Interstate 5 at the northern outskirts of Los Angeles and travels east to Interstate 10 in Redlands of San Bernardino County.  Interstate 210 is presently signed on the 44.9-mile segment of the Foothill Freeway between Interstate 5 and California State Route 57.  California State Route 210 makes up the remaining 40.41 miles of the Foothill Freeway east to Interstate 10.  Interstate 210 is still classified by the Federal Highway Administration as existing on what is now signed as California State Route 57 from San Dimas south to Interstate 10.  The focus of this blog will mostly be on the history of Interstate 210 segment of the Foothill Freeway.   Part 1; the history of Interstate 210 and California State Route 210 Interstate 210 (I-210) was approved as a chargeable Interstate during September of

Clovis "Gateway To The Sierras" sign and Tarpey Depot

Within Oldtown Clovis a fixture of the original alignment of California State Route 168 can be found in the form of the  "Clovis Gateway To The Sierras" sign. The sign was erected along Clovis Avenue in 1940 and was in use along California State Route 168 until the highway was relocated circa 1999-2001. Nearby Tarpey Deport can be found at the northeast corner of Clovis Avenue and 4th Street. The depot was constructed in 1892 as part of the San Joaquin Valley Railroad between Fresno and Friant. The depot structure was one previously located at the southeast corner of Clovis Avenue and Ashlan Avenue.
