The S stands for supplemental.SR 86S sign near an on-ramp on Dillon Road in Coachella.The route begins at an intersection with SR 86, from which it heads north as a divided expressway. SR 86S turns away from the Salton Sea as it heads through farmland. The route then meets SR 111, and turns northwest, running parallel to that highway. As it nears Indio, the expressway turns into a freeway. SR 86S ends at an interchange with I-10.
