U.S. 101 has many facets along its route throughout Golden State. Within Southern California, U.S. 101 is one of many routes that follow heavily traveled freeway corridors, including portions of the Santa Ana, Hollywood and Ventura Freeways. Colloquially known as "the 101" in the Southland, it is a very busy commuter route, including this stretch of the Hollywood Freeway where it Cahuenga Pass near Hollywood and Universal City in the city of Los Angeles. Other sections of U.S. 101 carry varying amounts of traffic, but it is always a primary route through any city it serves.
