The Colorado Department of Transportation (CDOT) has launched an automated speed enforcement program on Interstate 25 between the towns of Berthoud and Mead. Starting March 1, drivers exceeding the 65 mph speed limit in the work zone will receive warnings, with civil penalties of $75 for going 10 mph or more over the limit set to begin on April 2. The program aims to improve safety for drivers, workers, and law enforcement in the active construction zone, where the roadway is narrow with no shoulders.

Why it matters

Speeding is a major factor in crashes, with over 1,200 speeding-related crashes in Colorado resulting in 91 fatalities in 2025. CDOT's survey found that 70% of Coloradans admit to speeding on highways. The I-25 work zone between Berthoud and Mead poses particular risks due to the narrow roadway and lack of shoulders, making it difficult for drivers to react and for law enforcement to effectively monitor speeds.

The details

CDOT has installed eight speed cameras along the I-25 work zone that will photograph and timestamp vehicles exceeding the 65 mph limit by 10 mph or more. Drivers will have 45 days to pay the $75 fine or appeal the notice, with no points added to their license. The program is the second active corridor for CDOT's automated speed enforcement, following the Diagonal Highway between Boulder and Longmont.

  • The speed enforcement program began issuing warnings on March 1, 2026.
  • Civil penalties of $75 for exceeding the speed limit by 10 mph or more will begin on April 2, 2026.

What they’re saying

“When you have a high volume of traffic, and you see a constrained environment, the margin for error gets very small. That's true for any long-term construction that has barriers separating the traffic.”

— Benjamin Acimovic, CDOT Manager

“It's very hard for traffic at very high speeds to be able to react in that area.”

— Benjamin Acimovic, CDOT Manager

What’s next

CDOT will evaluate the performance of the speed enforcement program for the duration of the I-25 Express Lanes construction project, which is expected to be completed in 2028.

The takeaway

This speed enforcement program on I-25 between Berthoud and Mead is a proactive measure by CDOT to improve safety in an active construction zone with narrow lanes and no shoulders, where speeding poses a significant risk to drivers, workers, and law enforcement. The program aims to curb the high rates of speeding observed on Colorado highways and reduce speed-related crashes and fatalities.
