State Route 154 (also known as the Chumash Highway[2] or unofficially as San Marcos Pass 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. It is a 2 lane road with some passing lanes. It rivals US 101 for traffic, but it goes through the Los Padres National Forest and the San Marcos Pass. It starts in Los Olivos as a spur from US 101, goes through the town, and then passes Santa Ynez. It then reaches Lake Cachuma and passes through the Los Padres National Forest, across the Cold Spring Canyon Arch Bridge and the San Marcos Pass before descending to Santa Barbara. It then passes Cathedral Oaks before ending at US 101 near Calle Real.
This route is part of the California Freeway and Expressway System[3] and is eligible for the State Scenic Highway System[4].
