State Route 82 (SR 82) is a state highway in the U.S. state of California that runs from Interstate 880 in San Jose to Interstate 280 in San Francisco following the San Francisco Peninsula. It is the spinal arterial road of the peninsula and runs parallel to the nearby Caltrain line along much of the route. In addition, El Camino passes through many historic downtown neighborhoods such as Burlingame, San Mateo, Redwood City, Menlo Park, Palo Alto, Mountain View, and Sunnyvale, some of the most walkable and transit-oriented neighborhoods in the region.
