State Route 130 is a state highway in Santa Clara County, California that connects San Jose with the Lick Observatory on Mount Hamilton. The highway follows Mount Hamilton Road, a narrow two-lane highway that goes through the Diablo Range. Legislatively, SR 130 extends east from Mount Hamilton to Patterson in Stanislaus County, forming a route between the Santa Clara and San Joaquin valleys, but the traversable route via San Antonio Valley Road and Del Puerto Canyon Road is maintained at the county level and has not yet been formally adopted by the California Department of Transportation (Caltrans).
