CO Highway 151 remains closed south of the US Highway 160 junction, between Pagosa Springs and Arboles. Heavy spring run-off in Stollsteimer Creek, near Chimney Rock National Monument, has eroded the shoulder of the roadway causing a safety risk for drivers.   

Colorado Department of Transportation crews have been monitoring the site daily and working toward a temporary fix to get at least one lane open for alternating traffic. However, water levels must subside before any temporary or permanent repairs can be made.   

The closure was put into place last week, Tuesday, April 11, after CDOT was alerted of erosion issues on the highway caused by heavy spring run-off. Large volumes of water carrying natural debris washed away much of the creek channel and earth surrounding the metal culverts, causing a high potential for sinkholes to form underneath the road surface.
