Project Information
The Mountain Express Lane Project widens a 12-mile segment of westbound I-70 from the Veterans Memorial Tunnels to Empire Junction (U.S. 40). It is designed to improve safety and westbound operational mobility during peak travel periods along one of Colorado’s most congested corridors.
The project is scheduled to begin on Monday, July 15. It includes:Project completion is expected in late 2020, with toll system testing continuing through spring 2021, prior to the opening of the express lane.
- Increased capacity, travel time and trip reliability by converting the shoulder into an express lane that can be used during peak travel periods
- Enhanced advance warning signs, safety pull-outs and improved communication systems
The contractor for the $70 million project is Graham Construction of Denver.
Travel Impacts
This project will require shoulder closures and westbound lane closures during low volume traffic periods. A majority of the construction will be completed while both westbound lanes remain open by staging construction equipment in the eastbound express lane. This will minimize driver inconveniences by providing improved access to mountain destinations.

DENVER – The Colorado Department of Transportation (CDOT) and the High Performance Transportation Enterprise (HPTE) will host a series of telephone town halls on Tuesday, July 9, and Wednesday, July 10, to share information about the Express Lanes Master Plan with the public.
CDOT officials say that as the state continues to grow and develop, there’s a need to develop a statewide strategic Express Lanes Master Plan (ELMP) to proactively prepare for Colorado’s future needs.
CDOT will call residents in the Denver metro area and mountain communities along the I-70 corridor. If you don’t receive a call or would like to participate, call 855-710-6230.
