The name Mulholland Highway applies to a thirty-mile stretch that starts near Louisville High School in Calabasas and extends to its westernmost terminus at Leo Carrillo State Park on the Pacific Coast Highway. Wholly contained within Los Angeles County, the scenic byway was formally opened in 1928. Mulholland zigzags through the Santa Monica Mountains - one of the Southern California Transverse Ranges - from Oxnard all the way to Hollywood. Original major intersections included Topanga Road, Cornell Road, Latigo Canyon Road, and Decker Road.
