Grand & Clear Creek Counties - A safety closure may be necessary on US Highway 40 Berthoud Pass this afternoon due to avalanche conditions. Warm afternoon temperatures are loosening heavy snow from recent winter storms. This makes small avalanches, or bank slides, more likely along the roadway. Crews will be on standby to close the pass if conditions require a closure. The goal is to keep US 40 Berthoud Pass open as long as possible today, while continuing to protect the traveling public. If a safety closure is necessary, crews will continue to repair potholes on US 40 Berthoud Pass in locations that have safe avalanche conditions.

Two small avalanches came down onto US 40 Berthoud Pass in the area earlier this week. On Monday, April 10 and Tuesday, April 11, slides came down in the afternoon at approximately Mile Point 238. The area is located on the north side of Berthoud Pass, near Winter Park Resort. The slides came down onto the roadway during the afternoon and required short closures for snow removal. No vehicles were affected by the slides.

A safety closure on Thursday afternoon may also be necessary due to avalanche conditions.

Travel Impacts

If a safety closure is necessary, both eastbound and westbound motorists on US 40 will be affected. The closure would likely continue through the afternoon and until temperatures cool for the day. Motorists are encouraged to seek alternate routes. Motorists should be aware the closure times are approximate and may be extended should unusual circumstances arise. Travelers are advised to check for the most current information.
