Several Colorado roads were closed on Wednesday morning because of a winter storm that arrived as some people set out for Thanksgiving travel.

Various weather impacts are expected across the nation as almost 80 million Americans are set to travel for the holiday, the American Automobile Association reported. AccuWeather forecasts that “significant travel disruptions are anticipated for tens of millions” of travelers.

The busiest travel days were expected to be Tuesday and Wednesday. In Colorado, National Weather Service (NWS) meteorologists have issued a slew of winter weather warnings, with heavy snow expected to impact some roads for holiday travelers.

According to COtrip, a real-time traffic and roads website managed by the Colorado Department of Transportation (CDOT), several Colorado roads are closed on Wednesday because of poor conditions.

Newsweek has reached out to the CDOT by email for comment.

CO 9 Northbound was closed between County Road 4 and County Road 2 this morning because of a stalled vehicle, the department reported, with additional details warning of snow and ice on the road.

U.S. 550 was closed in both directions between County Road 31, 10 miles north of Silverton, and County Road 20D, 11 miles south of Ouray because of snow removal operations.

CO 65 appears to be closed in both directions, though the most recent update was issued on Tuesday evening. A photo showed whiteout conditions and CDOT cited safety concerns as the reason for closing the road.

U.S. 6 also still appeared to be closed after a Tuesday night update from CDOT. The closure is in place between Mile Point 222 and I-70; Loveland Pass (three to 10 miles east of Keystone) from Mile Point 222 to Mile Point 228.7. Photos showed dangerously snowy conditions and the NWS office in Boulder shared an image of the conditions on social media.

“CDOT cam from US-6 near Loveland Pass (closed) gives you a good idea of what snow removal crews are dealing with,” NWS Boulder posted on X, formerly Twitter, in the early hours of Wednesday morning. “1.5-2 ft of snow has fallen so far above ~10k ft with snow ongoing.”

CO 58 westbound was closed at Ford Street in Golden on Wednesday morning because of a crash, CDOT said.

Hazardous travel conditions could occur throughout the day, with several NWS winter storm warnings remaining in place until this evening.

“Travel could be very difficult to impossible. The hazardous conditions could impact the Tuesday morning and evening commutes,” one such warning issued by the NWS office in Grand Junction said. “If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency.”
