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:
Daytime milling and paving operations will begin along the eastbound lanes of I-70 on Monday, Oct. 12, and will continue for about a month. Crews will be working between the hours of 6 a.m. and 6 p.m. Monday through Thursday and 6 a.m. to 2 p.m. on Fridays.
This work will begin at mile point 232, which is the US Highway 40 interchange to Winter Park. On Monday, Oct. 12, and Tuesday, Oct. 13, both the eastbound I-70 off-ramp to US 40 and the US 40 on-ramp to eastbound I-70 will be closed between the hours of 6 a.m. and 6 p.m. There will also be a single lane closure along eastbound I-70 while this work is done. If necessary, work at this intersection will continue into Wednesday.
While these ramps are closed, eastbound I-70 drivers should continue to Exit 233 and turn left onto County Road 308 to reach US 40 and anyone traveling from Winter Park should go west on I-70 and exit at Georgetown (Exit 228) to access eastbound I-70.
When the widening work is finished near this interchange, crews will move their daytime paving operations to mile point 239 and begin working their way east toward Idaho Springs. This work will take about a month to complete and during this time, drivers can expect single lane closures and daytime travel delays through this area.
Beyond these paving operations, anyone traveling east on I-70 through Clear Creek County on Monday through Friday should plan for up to 30 minute delays between the hours of 8 a.m. and 3 p.m. and westbound drivers should plan for up to 30 minute delays between the hours of 10 a.m. and 5 p.m.
Work in the SH-103 intersections (Exit 240) on both sides of I-70 continues. During the week of Oct. 12 crews are scheduled to move to the south end of the bridge to do grading and paving work to bring the roadway elevation up to grade to match the bridge structure. This work will require alternate closures of the eastbound I-70 off-ramp to Exit 240 and the SH-103 on-ramp to eastbound I-70. During this week, drivers will be able to travel north and south over the bridge, but the bridge will be reduced to one lane of travel.
