California State Route 154

State Route 154 (SR 154) (also known as the Chumash Highway or unofficially as San Marcos Pass Road after the signage) runs from Los Olivos to Santa Barbara, California, USA. Before U.S. Route 101 was built, this was the main throughway to Santa Barbara and the tri city area including use as a Stagecoach route in early years. After being replaced by US 101 as the primary route between the Santa Ynez Valley and Santa Barbara, SR 154 now serves as a scenic alternative.
