State Route 27 is a state highway in the U.S. state of California that runs from Pacific Coast Highway (PCH) at Topanga State Beach near Pacific Palisades, through Topanga Canyon including the community of Fernwood Pacific also known as Topanga, and continuing through Woodland Hills, Canoga Park, West Hills, and Chatsworth to State Route 118. The entire route is commonly known by its street name, Topanga Canyon Boulevard.

As one of the only routes across the Santa Monica Mountains, Route 27 is heavily traveled by commuters from the western San Fernando Valley heading to Santa Monica or Interstate 10.^{[citation needed]}

Route description

SR 27 is eligible for the State Scenic Highway System.^[2] However, it is not officially part of the system as designated by Caltrans.^[3]

SR 27 begins at SR 1 right next to the Pacific Ocean and Topanga County Beach, in an unincorporated area of Los Angeles County between Malibu and Castellammare. It travels north as Topanga Canyon Boulevard, cutting through Topanga State Park. Upon exiting the park, SR 27 provides access to Fernwood, Topanga, Sylvia Park, and Glenview, all unincorporated. SR 27 continues winding into the San Fernando Valley, nearly entering Calabasas before entering the Los Angeles community of Woodland Hills. The route becomes a major city arterial through the valley, intersecting US 101 before entering Warner Center and Canoga Park. After traversing Chatsworth, SR 27 ends just past an interchange with the SR 118 freeway, thus providing access to the unincorporated area north of Chatsworth.^[4]

Metro Local line 245 runs on Topanga Canyon Boulevard.^{[citation needed]}
