CO 66 Intersection Improvements in Northeastern Colorado/Region 4

Starting on April 13th as final grading, seeding, & restoration is taking place, there are no anticipated traffic impacts for the remainder of the project. The hotline and project email will be monitored once a week on Thursdays and any outreach from the public will be addressed at that time.

About the Project:

CO 66 at Weld County Road (WCR) 7 and WCR 13 Intersection Improvements. This intersection improvement project includes two intersections. The traffic signal systems at both intersections will be replaced. Work at WCR 7 will also consist of adding a northbound left turn lane, and overlaying the entire intersection including new lanes a development is adding. The work will consist of minor earthwork, hot mix asphalt (HMA), traffic signals, bored conduit, signing, striping and traffic control.

Project Benefits

  • Upgrades improve traffic flow for motorists and enhance pedestrian safety at crosswalks
  • A new, smooth surface element that could be encountered by pedestrians that may cause trips or falls
  • The new signal system is being installed to accommodate future widening of both CO 66 and the Weld County Roads (WCR 7 & WCR 13)

Work Schedule:

  • Construction will begin on October 16, 2023
  • Working hours are Monday through Friday from 8 a.m. to 5 p.m.
  • The project is anticipated to end in late May 2024.
