Northern Colorado drivers traveling between Berthoud and Fort Collins will see a major change on Interstate 25 next week, as tolling begins on the newly completed Express Lanes. The 14-mile corridor will begin full operations on April 7, 2026, offering drivers a new option to bypass congestion during peak travel times.

Why it matters

The addition of tolling and targeted speed enforcement is expected to influence commuting patterns across Larimer County, particularly for residents traveling between Berthoud, Loveland, and Fort Collins. Officials say the adjustable pricing system is intended to keep traffic moving, while the camera enforcement focuses on improving safety in an active work area.

The details

Drivers will have multiple options for using the Express Lanes. Vehicles with one or two occupants can access the lanes by paying a toll, either through an ExpressToll account or via a license plate billing system. Toll prices will vary depending on traffic conditions and time of day, with overhead signs displaying current rates in real time. Carpools with three or more people can continue to use the lanes for free, but must have an ExpressToll account and a switchable HOV transponder set to 'HOV' mode. Motorcyclists are also permitted to use the lanes at no cost, without a transponder. Buses and transit services will have full access as well.

  • The 14-mile corridor will begin full operations on April 7, 2026.
  • Automated speed cameras are now active in the current construction zone just south of Berthoud, with camera systems positioned on both sides of the highway.
