U.S. Highway 101


U.S. 101 has many facets on its journey through the Golden State. In Southern California, it is one of many routes to 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 as it crosses Cahuenga Pass near Hollywood and Universal City in the city of Los Angeles. This view is taken from the west side of the freeway near Barham Boulevard looking northeast toward the off-ramp to Universal Center Boulevard. Other sections of U.S. 101 carry varying amounts of traffic, but it is always a primary route through any city it serves. Photo taken 02/26/11.
