Welcome to El Dorado County U.S. 50/Ponderosa Rd./So. Shingle Rd. Interchange Improvements Project Website

The El Dorado County Department of Transportation and California Department of Transportation (Caltrans) are in the planning process to modify the existing U.S. Highway 50/Ponderosa Road/South Shingle Springs Road Interchange and realign frontage roads at Durock Road, North Shingle Road and Wild Chaparral Drive. The County cannot adequately address all issues without input from those who are directly affected on a daily basis. Therefore, the public is encouraged to remain engaged throughout the process.
