Summary California State Route 1State Route 1 is a major north–south state highway that runs along most of the Pacific coastline of the U.S. state of California. At a total of just over 656 miles, it is the longest state route in California. SR 1 has several portions designated as either Pacific Coast Highway, Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 near Dana Point in Orange County and its northern terminus at U. S. Route 101 near Leggett in Mendocino County. The highway is designated as an All-American Road. It is part of the National Highway System, a network of highways that are considered essential to the country’s economy, defense, and mobility by the Federal Highway Administration. The Big Sur section from San Luis Obispo to Carmel is an official National Scenic Byway. The entire route is also designated as a Blue Star Memorial Highway to recognize those in the United States armed forces. In addition to providing a scenic route to numerous attractions along the coast, the route also serves as a major thoroughfare in the Greater Los Angeles Area, the San Francisco Bay Area, and several other coastal urban areas. For the most part the route runs parallel to the coastline, or close to it, but does turn several miles inland at various locations to avoid several federally controlled or protected areas such as Vandenberg Air Force Base, Diablo Canyon Power Plant and Point Reyes National Seashore.
