Eastbound I-70 Peak Period Shoulder Lane
The project, part of CDOT’s comprehensive plan to improve travel in the I-70 Mountain Corridor, will upgrade 13-miles of Eastbound I-70 within CDOT’s existing right of way. The upgrades will create the I-70 Mountain Express Lane; a wide shoulder that – only during peak travel periods – will operate as a third travel lane. The I-70 Mountain Express Lane will be dynamically priced to keep traffic moving. Prices will lower when CDOT wants to encourage drivers to use the lane and rise as the lane reaches capacity.

Utilizing the shoulder to create an express lane within the existing I-70 right-of-way during peak periods instead of adding a full lane has several benefits:

Current Construction Activity:
Throughout the spring there will be ongoing work along eastbound I-70 near mile point 240 to build the retaining walls at Water Wheel Park. Crews will also be pouring the plaza concrete, installing pedestrian railing and putting in the irrigation system and landscaping. This work will require single or double lane closures along eastbound I-70 as well as daytime closures of the Exit 240 (State Highway 103) on-ramp to eastbound I-70.
This work is expected to be done in early June and Water Wheel Park will then reopen to pedestrians.
On the east end of Idaho Springs work continues on the sidewalks and concrete islands along Colorado Boulevard at the Exit 241 interchange. Flaggers are on site during daytime hours to direct traffic in each direction through the roundabout and during the overnight hours two-way travel is maintained. Work on this bridge is scheduled to be substantially complete by June.
This spring there will also be work done on the bridge expansion joints at each of the seven bridges along the project corridor as weather conditions allow. This work entails removing sections of the asphalt pavement to take out the expansion joints and install new ones. This work will involve various single and double lane closures along eastbound I-70.
