US 6 Closed in Colorado Foothills After Heavy Rain Triggers Rockslides

U.S. Highway 6 closed in both directions through Clear Creek Canyon on Thursday morning, June 25, 2026, following multiple rockslides ^[1].

The closure disrupts a primary transit route through the Colorado foothills near Golden, forcing commuters and travelers to find alternative paths while crews clear debris.

According to the National Weather Service, heavy overnight rain triggered several rockslides in the region ^[2]. The slides blocked the roadway, making the highway impassable for vehicles in both directions ^[3].

Officials from the Colorado Department of Transportation (CDOT) managed the shutdown to ensure public safety. The agency said clean-up efforts will continue through the afternoon and evening ^[4]. CDOT also said they are asking drivers to avoid the area while the work proceeds ^[4].

The rockslides occurred in the steep terrain of Clear Creek Canyon, where saturated soil from the overnight storms often leads to instability. The National Weather Service said that the intensity of the rainfall was the primary catalyst for the geological shifts ^[2].

Crews are currently utilizing heavy machinery to remove the fallen rock and debris from the pavement. While no injuries were reported in the initial dossiers, the complete closure of the route has created significant traffic delays in the surrounding foothills ^[3].

CDOT has not yet provided a specific time for the highway to reopen, though they said the work would extend into the evening hours ^[4]. Drivers are encouraged to monitor official transportation alerts for updates on road conditions, and detour routes.
