Twin Bridges trailhead

Twin Bridges is a small unincorporated community on U.S. Route 50 near the Desolation Wilderness in El Dorado County, California. It is located 5 miles (8 km) west of Echo Summit, at an elevation of 6,115 feet (1,864 m). It has a population of 14 people according to census figures, however, as of 2008, the road sign lists the population as 10. Right after the town, the U.S. 50 eastbound starts a steep ascent to Echo Summit, passing Sierra-at-Tahoe ski resort shortly before the summit. When snow chains are required on the summit, Caltrans often establishes chain control in Twin Bridges.It is likely because of the limited availability of shoulders where chains can be installed on summit approaches.
