Travel Advisory

Sept. 28, 2026 - Southeastern Colorado - Temporary lane closure needed for weight station improvements

El Paso County — The Colorado Department of Transportation and its contract partner, Fleetworthy, is replacing aging Weigh-In-Motion equipment at the Monument Weigh Station the weekend of Oct. 9.

Single lane and shoulder closures should be expected on northbound Interstate 25 between Mile Point 159 and MP 161, from 9 p.m. on Friday, Oct. 9 through 5 a.m. on Monday, Oct. 12, allowing crews to install the new WIM scales. Northbound I-25 will be reduced to two lanes with a shift toward the median. Backups on I-25, especially at Exit 105 (Baptist Road) will occur, alternate routes suggested.

Work was planned during a weekend with the least impact to motorists as no major events are occurring in the Colorado Springs or Denver areas that would significantly impact travel on I-25. Work is weather dependent backup weekend is scheduled for Oct. 23 to 25.

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.
