Heavy rain triggered mud and rock slides on Thursday, forcing the closure of U.S. Highway 550 at Red Mountain Pass [1, 2, 3].
The closures disrupt a critical transit artery in Colorado's high country, known as the Million Dollar Highway, while simultaneous slides in other regions have created emergency rescue situations.
Colorado Department of Transportation (CDOT) crews are currently clearing debris from several slides that blocked the highway. Officials expect the road to remain closed through Friday, Aug. 1 [1, 3]. The slides were caused by several consecutive days of heavy rain that saturated the soil [1, 4].
"We are working around the clock to clear the slide and reopen the highway as soon as safely possible," John Smith, a spokesperson for the Colorado Department of Transportation, said [1].
Separate from the highway closure, massive mudslides occurred at the Curecanti National Recreation Area near Montrose [1, 4]. Reports indicate at least three major landslides struck the area [4]. These slides stranded 21 people, including hikers who are now the focus of search operations [4].
"Rescue crews are currently searching for the missing hikers stranded by the slides at Curecanti," Sarah Johnson of the Colorado Springs Gazette said [4].
CDOT and state officials continue to monitor the region as they manage the debris removal process. The closure of the Million Dollar Highway remains in effect until crews can verify the stability of the road surface [1, 3].
“"We are working around the clock to clear the slide and reopen the highway as soon as safely possible."”
The simultaneous occurrence of landslides at both a major transit corridor and a national recreation area highlights the vulnerability of Colorado's high-altitude infrastructure to extreme precipitation. The stranding of 21 people at Curecanti suggests that saturated soils are creating hazardous conditions beyond the roadway, potentially complicating emergency access and increasing the risk to outdoor recreationists during the current weather pattern.
