North I-25 Express Lanes: Johnstown to Fort Collins

Gov. John Hickenlooper broke ground on the I-25 North Express Lanes project Monday, Sept. 10. He was joined by Sen. Michael Bennet and many local, state and federal officials who helped make this project a reality.

Project Facts

  • Cost: $300+ million
    The U.S. Department of Transportation (USDOT) has awarded CDOT and local partners a TIGER grant to help it fund this expansion of North I-25.
  • Contractor: Kramer and IHC Construction Companies, LLC
  • Timeline:
    • First Notice to Proceed: Early 2018
    • Second Notice to Proceed: Summer 2018
    • Construction: Fall 2018 through fall 2019
    • Construction Complete/Toll Commencement: Early 2022

Travel Impacts

  • Crews have started construction on mainline I-25 between Crossroads Boulevard and Kechter Road, near CO 392. Construction in this area will be performed in two phases: full-width northbound followed by full-width southbound.

    While most of the work will be done off the road, some nighttime lane closures will be necessary.
    • Note: The Frontage Road will be permanently closed and removed at Larimer County Road (LCR) 30 to support the expansion of I-25 and the addition of an Express Lane in each direction. Those who need to access properties off the East Frontage Road must access them from the east on LCR 5/Fairgrounds Avenue.
  • Expect nighttime lane closures for the following:
    • setting barrier on both sides of I-25;
    • grade preparation and temporary asphalt paving; and
    • restriping I-25 for required traffic shifts, including removal of barrier.
  • Construction goals between CO 392 and Crossroads Boulevard include:
    • widening I-25 for additional Express Lanes;
    • relocating utilities;
    • erecting retaining wall under CO 392; and
    • constructing three water-quality ponds with accompanying drainage facilities.
  • 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.
