*Route 49 is accessible from Route 108 in Sonora via South Washington Street. Call City of Sonora for details. Route 49 is now open from Sonora to Angel's Camp; however, right turn NOT allowed in Angel's Camp from northbound Route 49 to eastbound Route 4.

**Cool and Coloma are accessible from SR 50 via N. Shingle Road, right on Green Valley Road, continuing on Lotus Road to SR 49. Call El Dorado County for details.

Note: Route segment lengths do not necessarily match postmiles due to postmile equations.
