James E. Roberts Bridge

The James E. Roberts Bridge is a road bridge that crosses the Tuolumne River near Chinese Camp in Tuolumne County. It carries two state routes over Lake Don Pedro and handles regular traffic between important regional destinations.

The bridge was originally called the Tuolumne River Bridge when it opened in 1971. It received its current name in 2007 to honor a Caltrans project manager who played a key role in its development.

The bridge stands as a testament to California's engineering excellence, receiving recognition through the AISC Medium Span Steel Bridge award in 1972.

The crossing has two lanes for regular traffic flow and is easily accessible from both sides. The area can be visited year-round, though summer temperatures tend to be warm.

The structure won the AISC Medium Span Steel Bridge Award in 1972, a notable recognition for its steel construction. This award highlights the engineering quality that made the crossing stand out.
