CO 52 Prospect Valley Resurfacing and Culvert Improvements

Project completed

About the Project:

The Colorado Department of Transportation began resurfacing a 2-mile stretch of roadway on CO 52 southeast of Keenesburg. This project also includes culvert replacement on County Road 79.

Work will primarily consist of resurfacing the roadway, using a two-step lifting and resurfacing process. The culvert replacement and repair will replace existing culverts on both CO 52 and CR 79. The culverts will be up sized and lengthened to allow for better drainage and safer, more resilient roadways.

“A smooth roadway has many important benefits including safety and improved quality for driving experience.” Said CDOT Executive Director Shoshana Lew. “This is an excellent example of how CDOT works to make sure rural roadways are maintained.”

Project Facts

  • Cost: $3.2 Million
  • Contractor: Zak Dirt
  • Timeline: May to  August 2022
  • Location:  CO 52 and CR 79 in Weld County

Work Schedule & Traffic Impacts

  • CO 52 will be closed to thru traffic east of CR 79 for approximately three weeks beginning early June while the roadway is being reconstructed and culvert is replaced.
  • During resurfacing, CO 52 will be reduced to a single lane at various mile points within the project limits during construction.
  • Alternating eastbound/westbound traffic will be directed flaggers within the single lane configuration.
  • Construction signs, cones and devices will be present 24/7
  • Width restriction of 10 feet will exist in the work zone
  • All construction schedules are weather dependent and subject to change.
  • Lane closures and other traffic notices are posted weekly on COTrip.org.
  • After those culvert replacements are complete, CR 79 will be closed for approximately one week to replace the culvert on CR 79.
  • Final roadway work will include striping, guardrail and shoulder work.
  • Daytime working hours are 7 a.m. to 8 p.m., Monday through Saturday. Vehicles may be reduced to a single-lane, alternating traffic intermittently in either direction, throughout the duration of the project. These lane closures, guided by flaggers, may have up to 15-minute delays. The speed limit in the work zone will be 40 mph (or less, as posted). Road work is expected to be complete by mid-August.
