US 85 Eaton to Ault Resurfacing

Project Facts

  • Cost: $10.5 million

Project Team

  • Contractor(s): Simon Contractors

On Monday, May 1, 2017, crews started resurfacing US 85 from Eaton to Ault. Work is expected to continue through summer 2018.

The project will:

  • Improve the quality of the highway.
  • Provide better drivability for motorists.
  • Eliminate potholes and divots in the road surface
  • Eliminate "faulting" that comes from the deterioration of an old road.


As of mid-August, crews are paving and have removed nearly all asphalt on the east side of the highway.

Unforeseen Issues Force Project Delay
During the asphalt-removal process, crews discovered extra layers of asphalt three feet below the old roadway—extending the entire length of the project. Because the soil consistency is clay-like—and absorbs moisture that can create an instable foundation—the original project timeline has been extended as crews mix a more solid material with the soil to strengthen the new foundation, and remove the additional asphalt layers.

Following this work, crews will shift the head-to-head traffic configuration onto the east side of US 85 (tentatively scheduled for late October). This configuration will mirror the current one on the west side, only it will be switched over to the newly paved section of roadway. With this alignment in place, crews can remove asphalt.

Upcoming Open House
Check this site frequently for details about an upcoming open house with the project team about the project schedule, and maintaining driveway and business access on the west side of US 85.


  • Normal working hours: 6 a.m. - 6 p.m., Monday through Friday
  • While no nighttime work is planned, crews will work up to four weekends at the CO 14 (Ault) and Collins (Eaton) intersection.

Traffic Impacts

  • An 11-foot width restriction is in place during the project.
  • Speeds will be reduced to 25 mph in the active work zone and 45 mph between the two towns.
  • The majority of the project will take place in a "crossover," where traffic will be arranged in a head-to-head configuration in either the northbound or southbound lanes of the highway.
Save the Date

We'll be hosting a project open house in spring 2018. Look for details about this event as spring approaches.
