Five-Way Intersection Improvements

The Project is located at the intersection of four roads serving local and regional traffic: SR 121 and local roadways Third Street, Coombsville Road, and East Avenue. The SR 121 intersection at Third Street/Coombsville Road/East Avenue is located in southeast Napa at post mile 7.35. The Project proposes to improve the intersection by constructing two, modern, single-lane roundabouts with curb, gutter, ramps, sidewalk, streetlights, and storm drain improvements. The proposed Project would ease traffic congestion by introducing a traffic-calming circulation pattern, improving community connectivity in the Project area, and improving pedestrian and bicycle safety within and adjacent to the intersection. Local circulation and access would largely remain unchanged.
