The City of Plymouth has approximately 7 miles of local roadways. State Highway 49 runs for just over a mile right through the center of town.

SR49 & Main Street Road Intersection is one only two intersections serving the City of Plymouth on Highway 49. This intersection has significance as it serves as the entrance to the Shenandoah Valley Wine Region as well as the connection between El Dorado and Amador Counties. In its current design, traffic congestion often is experienced with traffic queue backups on Main Street/Shenandoah Rd. during peak tourist season and events. In addition the intersection is both skewed, curved and has a significant elevation change from north to south creating a significant hazard for traffic entering from both directions of Main Street.

The City of Plymouth is working on a State Route (SR 49) & Main Street Roundabout Project that will construct a single lane modern roundabout at the intersection of SR49 & Main Street Road. The SR 49 & Main Street Roundabout Project is the top transportation priority for the City of Plymouth. The need and purpose of the project is to:

  • Improve Safety
  • Increase traffic capacity
  • Improve local circulation
  • Enhance economic viability of the SR49 & Main Street corridor
  • Improve operations
  • Improve pedestrian and bicycle access
  • Meet current standards

The construction project is expected to start in the first week of July 2017
