Lick Observatory
SR 130 did not exist as a state highway before 1964; however, the roads it travels had existed since Lick Observatory was built. Legislatively, SR 130 continues for 30 additional miles (48 km) east of Lick Observatory to State Route 33 in Patterson, California through the San Antonio Valley. East of the Lick Observatory, the road is maintained by the county rather than the state, and therefore this portion of the state highway remains technically unbuilt.
