Sonora Pass is the second-highest highway pass in the Sierra Nevada, lower by 321 ft. than Tioga Pass to the south. The pass is located on the border of Mono County and Alpine County, and State Route 108 traverses the pass.The pass connects the communities of Sonora to the west and Bridgeport to the east. Like most high Sierra Nevada passes, the highway is closed in winter, generally between November and May, due to snow accumulation.The highway over the pass is extremely steep (exceeding 8% for most of the traverse, and up to 26% grades in some locations), narrow and winding between Kennedy Meadows on the west side and Leavitt Meadows on the east. The route is not recommended for vehicles or vehicle combinations that are unusually wide, heavy or long.
