Resurfacing project begins on CO 79 in Prospect Valleythis week

Travel Advisory

January 24, 2019 - Northeastern Colorado

KEENESBURG — The Colorado Department of Transportation and prime contractor, Asphalt Specialties, plan to start resurfacing operations on Colorado Highway 79 beginning the end of January. 

Five miles of CO 79 will be resurfaced between Prospect Valley and the Adams County line during this federally-assisted $2.6 million project. Road improvements have not been made on this stretch of highway since 1992. 

In addition to resurfacing, plastic irrigation pipe along this route will be replaced and reinforced with concrete piping at 11 different locations. Because of piping material being compromised due to weather and aging, the road has given way at times, causing unsafe conditions. Removing the plastic piping and replacing it with concrete will mitigate the deterioration issues and provide greater stability and longevity.


  • Work on this project will begin at the end of January and go through July.

  • Normal working hours will be from 7 a.m. to 7 p.m., Monday through Friday. In special cases, these hours may be extended.

  • No weekend work is anticipated. 

  • 10-foot width restrictions will be in place for the duration of the project. 

  • Single-lane closures are expected.
