In early September 2013 , a section of US 36 from Estes Park to Boulder was closed due to damage from the 2013 Colorado floods . For a time , the only route available in and out of Estes Park was a long detour through Nederland , Blackhawk , and Golden . The section in North St. Vrain Canyon west of Lyons was especially heavily damaged . The road was finally reopened two months later with the help of the National Guard . Permanent repairs were started in January , 2014
