I-25 North Express Lanes: Johnstown to Fort Collins

Construction Update: Upcoming Frontage Road Closures and New Park-n-Ride Relocation

The Park-n-Ride lot at the southwest corner of Colorado Highway 402 and I-25 will be permanently relocated to the west of the existing lot. The new entrance will shift approximately 150 yards west of the existing entrance on CO 402. The existing lot will permanently close the night of Sunday, Jan. 13, 2019 at 5 p.m. The new lot is currently open for public use. Beginning Monday, Jan. 14, 2019, all vehicles must use the newly opened Park-n-Ride lot.

Crews will begin work on the old northbound I-25 lanes at CO 402 next week. This work will include milling existing pavement just north of the CO 402 and I-25 interchange. Flagging operations will be in place Monday through Friday 7 a.m. to 5 p.m. on the new temporary northbound I-25 on-ramp from CO 402 at River Ranch Parkway.

Median work continues north of Colorado Highway 392 with crews hauling dirt in and out of the median north of CO 392. Flagging operations will be in place Monday through Friday 7 a.m. to 5 p.m. on the northbound I-25 on-ramp from CO 392.

Preparations for Noise Wall erection at the Mountain Range Shadows Community will begin next week. A portion of the West Frontage Road, just north of East County Road 30 to North Peakview Drive, will experience intermittent lane closures creating a one lane road Monday through Friday 7 a.m. to 5 p.m.

Lane closures from Sunday, Jan. 13 through Saturday, Jan. 19: 

  • Monday – Friday: Daytime flagger assistance on the northbound I-25 on-ramp from CO 392.
  • Monday – Friday: Daytime flagger assistance on the northbound I-25 on-ramp from CO 402.
  • Monday – Friday: Daytime intermittent lane closures on the West Frontage Road just north of East County Road 30 to North Peakview Drive creating a single lane road in this area.

Construction activities are weather dependent and subject to change. Please watch for construction vehicles entering and exiting mainline I-25 and obey all posted signage in construction zones. Your safety and the safety of our crews is our highest priority.

The I-25 North Express Lanes Project provides a Courtesy Patrol during commute hours (6 to 9 a.m. and 3:30 to 6:30 p.m.) 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.
