State Route 88 (SR 88), also known as the Carson Pass Highway, is a California State Highway that travels in an east–west direction, from , crossing the Sierra Nevada at Carson Pass, and ending at the border with Nevada, whereupon it becomes Nevada State Route 88, eventually terminating at U.S. Route 395.
Unlike other two-lane California highways through the mountains (Routes 4, 108 and 120), Route 88 stays open through winter, except during the worst snowstorms, making it the third major route through the mountains, after Interstate 80 and U.S. Route 50. In fact, Route 88 over the Carson Pass is designated as Alternate U.S. 50, such that it may be used during floods of the American River Canyon.
SR 88 begins just outside as Waterloo Road, heading northeast towards Waterloo. The highway turns north at Waterloo, and SR 88 continues north to an intersection with SR 12, where the latter runs concurrently. SR 88 continues through Lockeford and Clements before continuing into Amador County. Continuing northeast, SR 88 intersects the southern terminus of SR 124 and is joined by SR 104 before passing through the town of Sunnybrook. SR 104 leaves SR 88 prior to the community of Martell, SR 88 continuing to Martell, where it joins with SR 49 and shortly thereafter turning south, running concurrently with SR 49 to the city of Jackson. In Jackson SR 88 turns northeast again leaving SR 49 at the intersection of SR 49, SR88 and Peek Street. The highway continues northeast through Pine Grove, Pioneer, Buckhorn, Cooks Station, and Ham's Station before entering the state game refuge. SR 88 continues paralleling the county line with El Dorado County in El Dorado National Forest before passing by Silver Lake and Kirkwood, where SR 88 crosses into Alpine County.
