SH 184 Culvert Replacement Project Underway West of Mancos

March 21, 2014 - Southwestern Colorado/CDOT Region 5 - MONTEZUMA COUNTY, CO – The Colorado Department of Transportation has a project underway to replace two critical culverts underneath SH 184 at Chicken Creek, west of Mancos at mile point 25.1.

The project involves replacement of two 40-year-old corrugated metal pipes. The contractor, Mountain Valley Contracting of Grand Junction, CO, will replace the two culverts through a pipe-jacking process, which will limit impacts to the roadway and to travelers.

Pipe jacking is a trenchless method of pipeline installation utilizing compressed air to drive the pipe through the ground. Typically, this type of installation does not require a highway pavement cut. Also at this site, crews will also fill an old, unused cattle underpass to remedy the roadside erosion it has caused.

Mountain Valley was contracted $849,050 for the project, which will protect the stability of the roadway and improving drainage.

TRAVEL IMPACTS – Through the project’s completion in late May 2014, Motorists can expect single-lane, alternating traffic Monday through Friday, during daylight hours. Duration: March 10 through May 2014
