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.
