State Route 88 (SR 88), also known as the Carson Pass Highway,[2][3] is a state highway in the U.S. state of California. It travels in an east–west direction from Stockton, in the San Joaquin Valley, to the Nevada state line, where it becomes Nevada State Route 88, eventually terminating at U.S. Route 395 (US 395). The highway is so named as it crests the Sierra Nevada at Carson Pass. The highway corridor predates the era of the automobile; the path over Carson pass was previously used for the California Trail and the Mormon Emigrant Trail. The mountainous portion of the route is included in the State Scenic Highway System.
SR 88 is one of the few trans-Sierra state routes that Caltrans attempts to keep open year-round. Caltrans has winter closures in effect for all Sierra Nevada highway passes between Carson Pass and Walker Pass (SR 178),[4] a span of over 200 miles (320 km). SR 88 follows a ridge to ascend most of the western slope of the Sierra Nevada.[5] The highway is occasionally used as a detour when U.S. Route 50, which follows the South Fork American River to ascend the Sierra Nevada, is flooded or otherwise closed.[6][7]
