The I-25 North Express Lanes between Colorado Highway 56 and Prospect Road opened for testing as of 5 a.m. Friday, Dec. 15. Tolls will be waived during the testing period, and drivers are encouraged to try the Express Lanes by entering through the dashed white lines. When using the lanes, drivers are reminded to follow these rules to ensure the safety of everyone on the road:
Do not cross the solid white lines (tickets for violations start at $75 each).
Enter and exit at the designated areas only, which are marked with a white dotted line.
Obey posted speed limits. The Express Lanes cannot be used to pass slower moving vehicles.
Motorists should expect various overnight and lane closures, including in the Express Lanes, while the last of the construction wraps up and tolling equipment is installed. The Express Lanes are anticipated to begin tolling in 2024. Once tolling begins in 2024, motorists are encouraged to sign up for an ExpressToll account to save an average of 40% on tolls.

About the Project
Communities along the I-25 North corridor are expanding rapidly, contributing to major economic growth in northern Colorado. The Colorado Department of Transportation is supporting this growth by delivering the expansion of I-25 North. Improvements are currently underway along I-25 between Berthoud and Fort Collins (with more to come from Mead to Berthoud).
This project brings economic, environmental and quality of life benefits for northern Coloradans by:
- Making safety improvements to reduce the number of crashes and fatalities.
- Decreasing travel time and increasing trip reliability.
- Reducing emissions and improving freight efficiency.
- Improve congestion and safety.
- Rebuilding aging and obsolete infrastructure.
- Improving bicycle, pedestrian and transit connectivity.
