Caltrans closes State Route 20 at Interstate 80 for bridge demolition | The Locally Times
Eastbound State Route 20 closes June 1 through June 3 for the $112 million Yuba Pass Separation Overhead Bridge Project.
Caltrans scheduled a 60-hour closure of eastbound State Route 20 at the Interstate 80 junction starting at 6 a.m. Monday, June 1, and ending at 6 p.m. Wednesday, June 3. The closure facilitates the demolition of a bridge pier and footing for the Yuba Pass Separation Overhead Bridge Project, the rebuild of the I-80 freeway overpass at SR 20. The agency postponed the work from earlier this week due to thunderstorms. ## Traffic Impacts and Detours Caltrans restricted eastbound State Route 20 between the Omega Scenic Overlook and the Interstate 80 junction for the duration of the work. Passenger vehicles must detour southbound on State Route 49 to reach Interstate 80 in Auburn or southbound on State Route 174 to connect with Interstate 80 in Colfax. Large trucks must use State Route 49 as their only designated detour. Crews also closed the eastbound Interstate 80 off-ramp to westbound State Route 20. Drivers must continue on eastbound Interstate 80 to the Eagle Lakes Road exit, then return westbound on Interstate 80 to access the off-ramp for westbound State Route 20. Westbound State Route 20 remains open between Truckee and the Nevada City/Grass Valley area. ## Construction Zone Safety Caltrans reduced the speed limit to 55 mph in the construction zone, with the California Highway Patrol providing traffic enforcement. The site remains accessible to emergency vehicles only. Flatiron Construction of Concord serves as the prime contractor for the bridge replacement, which is scheduled for completion by winter 2027. Beyond the bridge demolition, the project includes the installation of median barriers, drainage improvements, and the integration of roadway weather information systems, which provide real-time data on road conditions. Caltrans District 3, which manages 4,385 lane miles across 11 Northern Sierra and Sacramento Valley counties, directs motorists to the QuickMap application for traffic updates. ## Key Questions **When is the highway closed?** Eastbound State Route 20 closes between the Omega Scenic Overlook and the Interstate 80 junction from 6 a.m. Monday, June 1, until 6 p.m. Wednesday, June 3. **What detours are available?** Passenger vehicles may use State Route 49 to reach Auburn or State Route 174 to reach Colfax, while large trucks must use State Route 49.
