US 85 & Weld County Road 44 Interchange

Work this Week
June 27 - July 2, 2022

Anticipated construction activities and traffic impacts for the week of 6/27/2022 include:

  • Daily northbound and southbound US 85 left lane closures for median work (Monday - Friday, 7 a.m. - 5 p.m.)
  • Hauling embankment material to the site
  • Grading activities off the highway
  • Bridge work (prepare for bridge pier caps)
  • Intermittent flagger control on WCR 44 west of US 85 for site access
  • Expect frequent truck traffic and construction vehicles entering and exiting the work zone

About the Project:

A new grade-separated interchange will be constructed at the intersection at U.S. 85 and Weld County Road 44 in Peckham, Colorado. The purpose of the new interchange is to improve safety, eliminate interaction between roadway traffic and the Union Pacific Railroad (UPRR), and provide efficient access control.

A new grade-separated interchange is needed to address the following issues:

  • Safety – The current US 85 and WCR 44 intersection and roadway approaches experience higher than expected number of crashes due to the skewed angle of the intersection.
  • Railroad Proximity – The proximity of the UPRR and the US 85/WCR 44 intersection negatively impacts the operations and safety of the intersection.
  • Access – The current number, locations, and design of public roadway accesses have contributed to traffic operational and safety deficiencies along the corridor.

After considering several intersection configurations and discussing the alternatives with the public and local agencies, the new interchange includes the following improvements:

  • Moving the existing US 85 and WCR 44 intersection north along US 85
  • Continuing the grade-separation of WCR 44 over the UPRR to the east
  • Constructing a roundabout at the west end of the grade-separated interchange
  • Permanent closure of WCR 33 at US 85 and UPRR

Work Schedule

  • Work starts in December 2021.
  • Project completion expected in Late 2023.
  • All work is weather-dependent and the schedule is subject to change.

Traffic Impacts

  • US 85 will remain open during construction.
  • Since most construction activity will take place adjacent to the highway, only infrequent traffic impacts are anticipated on US 85.
  • General work hours are Monday through Friday, 7 a.m. – 5 p.m.,
    occasional extended hours and weekend work is possible.
  • Expect trucks entering and exiting the work zone. Frequent truck trips are anticipated for several months to haul materials to the site.
  • Speed limit reductions and width restrictions will be in place as needed.
