US 50 Cerro Summit Slide Repairs, Phase II

May 21, 2012 - Northwestern Colorado/CDOT Region 3 - MONTROSE COUNTY – The Colorado Department of Transportation and contractor Tricon 2, LLC, begin work today on the Cerro Summit Slide Repair, Phase II, on US 50 about 12 miles east of Montrose between mileposts 103.7 and 107. Tricon 2 was awarded a $2.2 million contract for this work.

Crews will be continuing work on the summit to make drainage improvements and highway repairs where the roadway has been slipping. These major repairs involve roadway excavation; placement of 12-foot deep, lightweight foam blocks to replace existing soils; followed by eight inches of new concrete; then road base (aggregates) material; and finally five inches of new asphalt.

Work on this project will be broken down into three sites, as follows (all areas will be resurfaced):

Mile point 103.7:       replacing existing soils with lightweight foam fill and drain installation

Mile point 105.8:       pipe replacement and rebuilding the roadway section

Mile point 107:          roadway reconstruction and addition of embankment material to flatten the below-highway hillside slope

TRAVEL IMPACTS – Through the project’s completion in late October 2012, work hours will be Monday through Friday, from 7 A.M. to 6 P.M.  (At this time no weekend work or holiday work is anticipated.)  Detour pavement will be added on the north side of the existing roadway and traffic will be shifted while the slide areas are excavated and repaired. Crews expect minimal traffic delays for the traveling public; however, there will be times when single-lane, alternating traffic will be directed by flaggers. Delays should not exceed ten minutes during these times.

CDOT and Tricon 2, LLC crews greatly appreciate your patience and cooperation while driving through the work zone. Thank you for going Slow for the Cone Zone!
