I-25 North Express Lanes: Johnstown to Fort Collins

 Full Closure of the Northbound I-25 On-Ramp From CO 392

To eliminate more than 20 overnight closures and accomplish expedited ramp work, the I-25 North Express Lanes: Johnstown to Fort Collins Project will require a full closure of the northbound I-25 on-ramp from CO 392 starting Friday, May 3, at 9 p.m., through Monday, May 6, at 5 a.m.

This closure is necessary to perform multiple ramp construction activities, including removing old pavement, reconditioning the subgrade, paving a new concrete ramp, relocating the ramp metering system and adding temporary asphalt paving with striping. By conducting a full weekend closure, the project eliminates the need for multiple additional overnight closures. 

For detour, take East County Road 5 north to East East Harmony Road.

Note: This closure is weather dependent and will be rescheduled for 9 p.m., Friday, May 10, until 5 a.m., Monday, May 13 if weather conditions prevent crews from completing necessary paving activities. 

 Take the I-25 North Express Lanes Project Survey

Participate in our online survey for the I-25 North Express Lanes Project. Our team wants to understand how much the traveling public knows about the project, how they travel and plan to travel, and how we can best communicate.

Work this Week
April 14-20

  • Monday – Friday: Daytime intermittent lane closures on the NE Frontage Road between Mulberry St. and the Great Western Railway creating a single-lane road
  • Monday – Saturday: Daytime flagger assistance on the northbound I-25 on-ramp from CO 392
  • Monday – Saturday: Daytime flagger assistance on CO 402 east and west of I-25

 From 6 to 9 a.m., and from 3:30 to 6:30 p.m., this project provides a Courtesy Patrol to assist with disabled vehicles within the project limits.

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 I-25 North.
  • Contractor: Kraemer 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

In mid-October, crews began construction near CO 402. There will be three main phases of work in this area that will continue through mid-2020:

  • Phase 1 will allow crews to build temporary infrastructure on the southbound side of I-25.

  • Phase 2 will push northbound traffic onto the southbound side to provide access to build infrastructure on the northbound side.

  • Phase 3 will switch northbound and southbound traffic onto the northbound side to allow crews to build the required infrastructure on the southbound side.

What to Expect

  • While most of the work will be performed outside the roadway, some nighttime lane closures will be required. CDOT will send advance notification of these closures.
  • Current work between Crossroads Boulevard and Kechter Road, near CO 392, will continue during construction at CO 402.

Coming Up....

  • In late summer 2019, crews will close CO 402 between the I-25 ramps. Watch for more details in spring 2019.
  • Once the project is complete, CO 402 will run over I-25.

Key Project Features

  • 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.
