Statewide $2.5 million weigh-in-motion scale upgrade project underway in Colorado

The Colorado Department of Transportation (CDOT) is at work on a project to upgrade aging Weigh-In-Motion (WIM) equipment at weigh stations across the state.

From now through October 2026, CDOT crews are at work on a $2.5 million project to replace WIM scales at seven locations throughout Colorado. Crews will also remove one weigh-in-motion scale station in Platteville.

On July 6 and 7, CDOT will work on completing the WIM scale upgrade at Fort Morgan. Drivers should expect a half-mile, single lane closure on westbound I-76 at mile marker 75, five miles south of Fort Morgan, 24 hours a day.

Starting on July 8, crews will move on to upgrade with WIM equipment at the Limon Weigh Station. As part of this project, CDOT will shut down one lane on westbound I-70 at mile 361, 24 hours a day, through Friday, July 17.

After the Limon WIM replacement is complete, crews will move on to the following locations:

Upon completion at Limon, the project shifts to the following weigh stations:

• I-25 – Monument
• I-25 – Trinidad
• I-70 – Loma
• I-70 – Dumont
• US 50 – Lamar

CDOT says drivers should expect reduced speeds and minor delays at these locations during construction.

“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,” CDOT said.
