Weigh-In-Motion Project Moves to Limon on I-70

Colorado Upgrades Weigh-In-Motion Systems at Seven Truck Inspection Sites

Truck drivers traveling through Colorado should expect temporary lane closures this summer as the Colorado Department of Transportation (CDOT) upgrades Weigh-In-Motion (WIM) equipment at weigh stations across the state.

The statewide project is designed to modernize truck weighing technology, allowing commercial vehicles to be screened more efficiently while helping improve traffic flow and roadway safety. The work is expected to continue through October 2026 and includes improvements at seven weigh station locations across Colorado.

Weigh-In-Motion Project Moves to Limon

CDOT announced that crews have completed work at the Fort Morgan weigh station and are now moving to the Limon Weigh Station along westbound Interstate 70.

Beginning July 8, one lane will be closed for approximately one-half mile near mile marker 361 on westbound I-70. The closure is expected to remain in place through July 17, with one lane staying open to traffic at all times.

Drivers should expect reduced speeds and minor delays while crews replace existing concrete, WIM scales, sensors, and other system equipment. Twenty-four-hour lane closures are necessary to allow newly poured concrete to cure properly, and construction schedules remain weather dependent.

What Is Weigh-In-Motion Technology?

Weigh-In-Motion systems allow commercial trucks to be weighed while traveling at highway speeds instead of requiring every vehicle to stop at a static scale.

According to CDOT, the technology offers several benefits:

• Increases the number of trucks that can be screened
• Improves traffic flow near weigh stations
• Reduces idling and vehicle emissions
• Helps identify overweight vehicles more quickly
• Protects highways and bridges from excessive weight
• Improves safety around inspection facilities

More Colorado Weigh Stations Will Receive Upgrades

The Limon project is one phase of CDOT’s $2.5 million statewide modernization program.

After work is completed in Limon, construction crews will move sequentially to:

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

Earlier phases included work at Platteville and Fort Morgan.

Each location is expected to require approximately one to four weeks of construction, depending on site conditions. Additional traffic advisories will be released before work begins at each weigh station.

What Truck Drivers Should Expect

Although the upgrades may result in temporary delays near active construction zones, the long-term goal is to improve how commercial vehicles move through Colorado’s weigh stations.

By replacing aging equipment with newer Weigh-In-Motion technology, CDOT aims to process more trucks without requiring as many vehicles to stop, reducing congestion while continuing to identify overweight loads that can damage roads and bridges.

The statewide project is scheduled for completion in fall 2026.
