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:
The evening of Monday, Aug. 31, I-70 will be reduced to one lane of travel in each direction and detoured up and over the highway at Exit 241 in east Idaho Springs so crews can set the girders for the new bridge. Click here to see a map of these detour routes. Westbound I-70 will be taken down to one lane of travel on the east side of the Veterans Memorial Tunnels at 5 p.m. and eastbound will be reduced to one lane of travel near mile marker 240 starting at 6 p.m.
Crews are scheduled to have all lanes of I-70 open by 7 a.m. Tuesday, but the eastbound lane could open a little later. If needed, a similar detour will be in place the night of Tuesday, Sept. 1, to finish the work. When crews pour the concrete bridge deck this fall, a similar detour will be in place for both directions of I-70.
Overnight milling and paving activities continue along the eastbound lanes of I-70 between mile markers 232 and 241 on Sunday through Thursday nights. This work will involve the following on-ramp and off-ramp closures along eastbound I-70:
