Resurfacing on I-70 Vail Pass to begin in Summit County

Project Update

September 12, 2023 - Northwestern Colorado - Daytime right lane and shoulder closures with 10 to 20 minute delays

Summit County — Beginning Sept. 13, the Colorado Department of Transportation will resurface the eastbound right lane on I-70 Vail Pass from Mile Point 190, west of Copper Mountain, to MP 203, just east of Frisco. Motorists can anticipate daytime single lane and shoulder closures with 10 to 20 minute delays. Daytime work is necessary due to nighttime pavement temperatures. There will not be lane closures during nighttime hours, on weekends or on holidays.

Contract partner Elam Construction, of Grand Junction, will mill the existing asphalt and pave 2 inches of new hot mix asphalt. The project will improve 13 miles of worn out roadway of eastbound I-70 right drive lane. The right lane receives more travel, causing faster deterioration of that lane’s pavement condition. The new asphalt will extend the life of the highway, provide a smoother road surface and will add durability by increasing the resistance of ruts and road damage.

The work is part of a larger series of critical pavement repairs in Colorado’s High Country. CDOT is investing additional funds received earlier in 2023 to address pavement conditions after heavy winter snows. Twelve stretches of roadway across the state were identified, including three along or near the I-70 Mountain Corridor. Work is also taking place on US 40 Berthoud Pass and CO 125 in Grand County.

Traffic Impacts

Motorists should plan for a right lane and shoulder closures, with 10 to 20 minute delays. Traffic impacts are anticipated to take place Monday through Friday, from 7 a.m. to 7 p.m. Occasion off-ramp closures will be necessary for crews to pave near ramps. The project is anticipated to be complete Nov. 2023.
