Improvement project at Trinidad Weigh Station this week

Trinidad — The Colorado Department of Transportation is replacing aging Weigh-In-Motion equipment at the Trinidad Weigh Station later this week. 

Single lane and shoulder closures should be expected on northbound Interstate 25 (mile 10.5) for approximately one-half mile, from 8 a.m. to 6 p.m., Wednesday, July 22 through Friday, July 24, allowing crews to relocate the existing cabinet, the mast arm pole and install new WIM scales.

WIM technology allows trucks to be weighed at highway speeds without requiring them to stop at a weigh station scale. Doing so significantly increases the number of trucks that can be weighed, improving traffic flow and road safety around each station. A WIM system also helps reduce emissions by eliminating idling and it protects the state’s bridges and road surfaces by quickly identifying overweight vehicles. 

Upon completion at Trinidad, the project shifts, sequentially, to the following weigh stations (sequence subject to change): 

  • I-70 – Loma 
  • I-25 – Monument
  • US 50/287 – Lamar 
  • I-70 – Dumont
  • US 85 – Platteville (Complete)
  • I-76 – Fort Morgan (Complete)
  • I-70 – Limon (Finishing work/completion next week)

Work is expected to take approximately one to four weeks, depending on the specific project requirements at each weigh station. Additional information regarding traffic impacts will be distributed before work begins at each location. 

The project is scheduled for completion in fall 2026.

Fleetworthy is the project’s prime contractor.
