Another eastward, SR 49 joins from the south and is co-routed with SR 108 through Jamestown and into Sonora, where SR 49 departs to the north. SR 108 continues eastward and gains elevation as it passes through Twain Harte, Mi-Wuk Village, Long Barn, Cold Springs, Strawberry-Pinecrest Lake and Dodge Ridge Ski Area, then on to Dardanelle and Kennedy Meadow. SR 108 passes through Alpine County for approximately 0.8 miles immediately west of the Sonora Pass. At the pass, the highway crosses the summit of the Sierra Nevada and enters Mono County, then descends past the Mountain Warfare Training Center at Pickel Meadows, finally reaching the eastern terminus at Sonora Junction where it meets U.S. Route 395.
