Del Puerto Canyon Road

[Max Rockatansky]

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.
