Mudslides Close I-70 in Western Colorado, Disrupt Travel
US · Published Jul 22, 2026
Interstate 70 in western Colorado has been closed in both directions for over 24 hours due to a significant mudslide caused by torrential rain and hail on Monday evening. The mudslide deposited debris, mud, and water across a 300-yard stretch of the highway, with some areas reaching depths of up to 3 feet. The closure affects the section between exit 97 near Silt and exit 105 near New Castle, with detours redirecting traffic onto U.S.
Additional closures have been reported on Peach Valley Road and County Road 214 due to flash flooding. Heavy rains also caused debris flows along the Colorado River, prompting warnings against boating in affected areas. More rainfall is forecast for the region, increasing the risk of runoff and further disruptions.

Impact & Risks

The mudslides and flash flooding have disrupted travel and posed safety risks to residents and travelers in western Colorado. Roads, including I-70 and local county roads, are impassable due to debris and swift-moving water. The Colorado River has also been affected, with boating conditions deemed unsafe. Burn scars from previous wildfires exacerbate the risk of debris flows, as vegetation that would typically absorb rainfall has been stripped away. State transportation crews are monitoring conditions closely and may implement additional road closures if necessary.
