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.
