State Route 86 (SR 86) is a north–south state highway in the southeastern desert region of Southern California, United States. It runs from State Route 111, near the Mexican border crossing at Calexico, north through the Imperial Valley via El Centro and Brawley, and around the west side of the Salton Sea into the Coachella Valley. It joins State Route 111 at Coachella and heads into Indio, ending at the intersection of Indio Boulevard and Avenue 46, where SR 111 turns west onto Avenue 46. (The locally-maintained Interstate 10 Business continues northwest on Indio Boulevard, as did SR 86 before that portion was removed from the state highway system.)
