It’s not only the debris blocking the road that is causing issues, but that debris caused “extreme damage” according to the Colorado Department of Transportation. More heavy rain and flooding hit the area on July 31 just a little more than a day after more than 100 drivers were caught in the mud and debris and had to be rescued.READ MORE: Robert Killis, CSU Pueblo Student Arrested After Detectives Find Large Cache Of Weapons, Ammunition In Vehicle, Apartment
