North I-25 Express Lanes: Johnstown to Fort Collins

The U.S. Department of Transportation (USDOT) has awarded CDOT and local partners a TIGER grant to help it fund a $237 million expansion of North I-25.

Key project features will:

  • Increase capacity by adding an Express Lane in both directions, replacing four aging bridges and widening four additional bridges.

  • Improve multi-modal access to regional transit to promote mode shift.

  • Improve bus service performance and reduce each total trip time by 15 minutes by adding new bus slip ramps from I-25 to the new Park-n-Ride at Kendall Parkway.

  • Create new pedestrian, bicycle access under I-25 at Kendall Parkway.

  • Connect the Cache la Poudre River Regional Trail under I-25 and network to 100 miles of total trails. It will also serve as a wildlife corridor.

This project brings critically important benefits to the economy, the environment and quality of life by leveraging resources from partners across northern Colorado. Benefits include:

  • safety improvements;
  • reducing accidents and fatalities;
  • reducing travel time and increasing trip reliability;
  • reducing emissions;
  • improving freight efficiency;
  • increasing travel choices;
  • reconstructing aging and obsolete infrastructure;
  • improving bike/pedestrian and transit connectivity; and
  • employing congestion management and safety technology to improve overall conditions.

Local partners and elected officials have been heavily involved in the planning, implementation and funding of this critically important project.

In 2013, an I-25 Coalition was formed to help manage and accelerate improvements to the corridor. Six northern Colorado communities, Weld and Larimer counties, CDOT, chambers of commerce and private businesses have all been collaborating to help bring these improvements to fruition.

The I-25 Coalition has grown steadily and is currently made up of 90 representatives from Adams, Larimer and Weld counties, Berthoud, Broomfield, Dacono, Erie, Firestone, Fort Collins, Frederick, Johnstown, Loveland, Mead, Northglenn, Timnath, Thornton and Windsor, as well as CDOT, businesses and other interested agencies.
