Caltrans widening I-80 westbound on-ramp at Atlantic Street

Updated March 02, 2021
On Wednesday, March 3 Caltrans began major construction work to widen the Interstate 80 westbound on-ramp at Atlantic Street. Completion is expected in fall 2022. 

The project is expanding the width of the existing single lane Atlantic Street/Eureka Road/Interstate 80 westbound on‐ramp to include three lanes and replacing the existing bridge to support the newly widened roadway. The updates will reduce significant traffic backup and improve the operations of local streets and intersections. 

A portion of the Miner's Ravine Trail will be closed from March through October 2021. Please use the detour shown below, or choose an alternate route. Signs will mark the closed area. Other temporary trail closures may follow. Subscribe to Trail Alerts and follow us on social media to stay informed. Visit
