Gov. Polis to issue state disaster declaration in Glenwood Canyon from I-70 mudslides CDOT GLENWOOD SPRINGS, Colo. (KRDO) -- I-70 through Glenwood Cayon will remain closed due to "extreme damage" caused by heavy rain and flooding. Engineers with the Colorado Department of Transportation described the damage as "unlike anything they had seen before." In late June, CDOT closed a portion of I-70 following several mudslides. Since then, CDOT crews have been dealing with continued rain, flooding, and debris washing onto the highway. Monday, Governor Jared Polis, along with CDOT officials and the executive director of the Colorado Department of Public Safety, addressed the state about the ongoing situation in Glenwood Canyon.
