Although the continuous highway along the California coast is Highway 101, there are many places where no high speed, high volume road is possible. When this happens, Highway 101 follows an inland route and the highway that follows the shoreline is Highway 1.
North of San Francisco, Highway 1 begins near Leggett and follows the coastline through Fort Bragg and Mendocino, rejoining Highway 101 just north of the Golden Gate Bridge. South of the bridge, Highway 1 breaks off again, going through San Francisco before returning to the coast at Pacifica. South of Pacifica, it continues along the coast through Monterey and Big Sur. For a few miles south of San Luis Obispo, it coincides with Highway 101 again. It separates to go through Lompoc, rejoins 101 along the Santa Barbara Channel, finally taking its own path at Ventura, following the coastline through Malibu, past Los Angeles and finally terminating where Interstate 5 reaches the coast just north of San Clemente.
