U.S. 101 - Bayshore Freeway/South Valley Freeway

U.S. 101 is major north-south highway that spans the three Pacific coast states, Oregon, Washington and California. U.S. 101 north starts at Interstate 5 in downtown Los Angeles and ends at Interstate 5 in Olympia, Washington after circling the Olympic Peninsula. U.S. 101 is mostly freeway or expressway through California but narrows to 2 lanes in Oregon and Washington.

As U.S. 101 enters Santa Clara County, it's a 4-lane expressway but quickly becomes a freeway outside of Gilroy. It was recently widened to 8 lanes between Cochrane Road (Exit 367) and Bernal Road (Exit 377A).

At this point, U.S. 101 leaves Santa Clara County and enters San Mateo County on its way to San Mateo, San Bruno and San Francisco.
