SR 183 begins in the center of the city of
Salinas at an at-grade interchange with
U.S. Route 101. The road then heads toward the center of Salinas along North Main Street before abruptly turning northwest along Castroville Road. Following an interchange with Davis Road, the route exits town and enters an area covered with farmland. It continues through this central
Monterey County while gradually turning north until it reaches southern
Castroville, where it again turns northeast. The road then interchanges with
State Route 156 and traverses northeast as the western boundary of Castroville before meeting its northern terminus,
State Route 1, the Cabrillo Highway. SR 183 is part of the
California Freeway and Expressway System, and in Salinas 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. ==History==
