Highway 26/49 Intersection Control Improvement Project
Project Description
This Safety Improvement project proposes to construct a roundabout at the intersection of State Route (SR) 26 and SR 49 in the town of Mokelumne Hills in Calaveras County to reduce the number and severity of broadside collisions at the intersection. Three alternatives were proposed including the No-Build alternative. Alternative 1 proposes to construct a roundabout, and Alternative 2 proposes to install a traffic signal with left-turn lanes.
Caltrans will install a closed-circuit television (CCTV) camera as part of the Transportation Management System (TMS).
The camera provides live traffic monitoring to help manage traffic, respond to incidents, and evaluate roadway operations. It also allows the Caltrans Traffic Management Center to quickly assess traffic conditions and coordinate responses with law enforcement, maintenance crews, and emergency responders.
The camera does not record video and is not used for law enforcement or enforcement purposes.
