California 46 is the major east-west route from the Central Coast to the Central Valley. The route is mostly two lanes, but plans call for the route to upgraded to four lanes. Beginning near Cambria on the California Central Coast, California 46 travels east to Paso Robles, then passes over the Coast Range and crosses the Central Valley along the former U.S. 466 alignment all the way the junction with California 99. While California 46 ends at California 99 in the Central Valley at a point northwest of Bakersfield, historically U.S. 466 continued southeast into Bakersfield, then crossed the Tehachapi Mountains via California 58. U.S. 466 was decommissioned in favor of California 46 and California 58 in 1964.
