I-80 Speed Limit Change in the Westbound Tunnel Near Green River

123

The Wyoming Department of Transportation (WYDOT) has adjusted the speed limit from 35 MPH to 50 MPH in the westbound I-80 tunnel near Green River. After working closely with consultants and the Wyoming Highway Patrol, crews reviewed the lighting in the westbound tunnel, evaluating the current level of visibility for drivers to establish a safe driving speed.

“We wanted to make sure we could safely raise the speed limit in order to help traffic flow more effectively through the area,” WYDOT resident engineer Clint Lockman said.

Crews will continue to monitor traffic flow and speeds through the tunnel throughout the winter. Drivers are reminded that although the speed limit has been adjusted, they should continue to be mindful when driving in winter conditions. This includes checking road conditions before traveling, driving at a speed suitable for the conditions, and watching for snowplows.

Oversized vehicles should continue to contact the Wyoming Highway Patrol’s oversize loads permit office for detours.
