Clear Creek County - Colorado Department of Transportation crews have started clean-up operations Monday morning, June 16, of a mountain slide that is approximately 100 ft. wide and 15 to 20 ft. deep at Mile Point 226 on Loveland Pass (US 6). The mountain slide occurred at 5:30 a.m., Sunday, June 15. The material above the roadway became saturated by melting snow and slid onto the roadway.

The clean-up operations will be done in two stages. The first stage will remove the mud and silt from the travel lanes. Once that is complete, the slide will be assessed again to make sure it is stable. The second stage will clean the remainder of the slide.

While crews are working diligently to clear the slide, there is no estimated time as to when Loveland Pass will re-open. It will not re-open to traffic until the roadway is safe. Motorists, hikers and cyclists are urged to stay away from the area until the clean-up is complete.

There is a record of this area partially sliding in 2003, but it stabilized on its own shortly afterward, with no history of movement over the past 22 years.

Due to the Loveland Pass closure, CDOT is escorting trucks carrying hazardous materials through the I-70 Eisenhower-Johnson Memorial Tunnels (EJMT) at the top of the hour. At that time, traffic will be held for hazmat vehicles to drive through. Hazmat vehicles are not allowed through the EJMT due to safety concerns, but when Loveland Pass is closed, they are escorted through the tunnel.

Note to newsrooms: No media availability on the site today, June 16. Crews are operating in a safety-sensitive environment with limited room to maneuver.
