CDOT warns travelers to anticipate heavy holiday traffic statewide

Travel Advisory

Dec. 22, 2025 - Denver Metro/Central Colorado - Plan to drive sober, take it slow, and give yourself plenty of time to arrive safely

Denver — The Colorado Department of Transportation is reminding drivers to expect heavier traffic in many areas of the state over the next couple of weeks as people prepare to travel during the holidays. Drivers should expect increased traffic along the Front Range before and after the Christmas holiday, due to the number of large shopping areas located on or near the urban corridors.

“Wherever your travels take you, plan to drive sober, take it slow, and give yourself plenty of time to arrive safely,” said CDOT Executive Director Shoshana Lew. “We ask every driver to respect the road and each other so we can all enjoy the holiday season.”

To ease holiday traffic, CDOT will suspend construction projects statewide by noon on Wednesday, Dec. 24, and Wednesday, Dec. 31. No work is scheduled for Thursday, Dec. 25 and Thursday, Jan. 1, 2026. In addition, there will be no lane closures on the I-70 Floyd Hill project on Saturday, Dec. 20, 2025, until Monday, Jan. 5, 2026. As always, motorists are encouraged to check COtrip.org or the COtrip Planner app for real-time alerts and specific project details. Project details can also be viewed online at codot.gov/projects.

I-70 Mountain Corridor Travel

Heavy traffic also is anticipated along the I-70 Mountain Corridor between Denver and Eagle County during the week following Christmas due to traditional increases in recreational travel. Christmas week is one of the higher travel periods in Colorado.
