Project Facts


The California Department of Transportation (Caltrans) proposes to improve the safety of the intersection at State Route 26 and State Route 49 in Calaveras County in the town of Mokelumne Hill. A Traffic Collision Report from the California Highway Patrol and a Traffic Investigation conducted by the District 10 Traffic Safety Branch identified a pattern of broadside collisions at this intersection. A Traffic Signal Warrant Analysis was performed, and the results found the intersection meets signal warrants. Three alternatives are being proposed. Alternative 1 proposes to construct a roundabout, Alternative 2 proposes to install a traffic signal, and Alternative 3 is the no-build option leaving the intersection as it is.
