Culvert Rehabilitation Scheulded in Southwest and South Central Colorado

August 25, 2016 - Southwestern Colorado/CDOT Region 5 - SW and S CENTRAL COLO: The Colorado Department of Transportation (CDOT) will begin a culvert rehabilitation project at three locations in southwestern Colorado as part of its statewide effort to rehabilitate culverts in need of repair.

The work is scheduled to take place from Tuesday, Sept. 6 through Thursday, Nov. 15.

The three project locations include:

  • Conejos County – CO Highway 17 at mile point (MP) 3.18, between the New Mexico border and Cumbres Pass;

  • Montezuma County - US Highway 160 at MP 3.67, just north of the Four Corners Monument;

  • Chaffee County - US Highway 24 at MP 206.63, about two miles north of Buena Vista.  

Work will only be occurring one site at a time, with the work in Conejos and Montezuma Counties occurring first, then moving on to the Chaffee County location.

The culverts will be rehabilitated by use of slip lining, which involves inserting a plastic liner inside of each existing culvert.  This method of rehabilitation eliminates the need to dig up the road in order to replace the culvert, thus reducing the cost and impact to the traveling public.

TRAVEL AND ACCESS IMPACTS:  Most of the work will be occurring off of the roadways.  However, in the construction zone there will be reduced speeds, shoulder closures, and limited single lane closures with flaggers during equipment and material deliveries.  Work will be performed only during daylight hours and will include some Saturday work.
