120-day closure of CO 402 at I-25 rescheduled to June 24

May 31, 2019 - Continued weather events have created wet ground conditions preventing crews from completing necessary pre-closure activities

The 120-day closure of Colorado Highway 402 at Interstate 25, scheduled to begin on June 10 has been rescheduled to begin the night of June 24. Continued weather events have created wet ground conditions preventing crews from completing necessary pre-closure activities.

Beginning the night of June 24 through the morning of Oct. 22, CO 402 will be fully closed from the southbound I-25 on- and off-ramps to the new southeast frontage Road for 120 days.The Park-n-Ride on the southwest side of I-25 on CO 402 will remain open during this closure.

By the end of 2019, the I-25 and CO 402 interchange will undergo substantial changes, resulting in a new and safer interchange as part of CDOT’s Whole System – Whole Safety initiative. Reconstruction will improve the safety of the travelling public on I-25 by smoothing out the curve, both horizontally and vertically, adding pedestrian and bike facilities to allow safe crossings of I-25, accommodate the continuing population growth in the Loveland and Johnstown area and modernize the aging infrastructure.

Once completed in October 2019, the new configuration at CO 402 will be fully operational, and future impacts at this interchange will be minimal.

For northbound I-25 access from the west side of I-25 on CO 402, take southbound I-25 to Colorado Highway 60 (Exit 252), turn left and continue back onto northbound I-25.

For eastbound CO 402 access, continue on southbound I-25 to CO 60 (Exit 252), then take the ramp to northbound I-25 and exit CO 402 eastbound.

For southbound I-25 access from the east side of I-25 on CO 402, take northbound I-25 to US 34/Eisenhower Blvd (Exit 257), turn left and continue back onto southbound I-25.

For westbound CO 402 access, continue on northbound I-25 to US 34 /Eisenhower Blvd (Exit 257), then take the ramp to southbound I-25 and exit CO 402 westbound.


The I-25 North Express Lanes: Johnstown to Fort Collins Project will increase capacity by adding an Express Lane in both directions, replacing aging bridges at four locations and widening two additional bridges. The project will also improve multimodal access to regional transit to promote mode shift, improve bus service performance by adding new bus slip ramps from I-25 to the new Park-n-Ride at Kendall Parkway, create new pedestrian and bicycle access under I-25 at Kendall Parkway and construct new bridges over the Cache la   Poudre River, allowing for the future completion of the regional trail. The project is expected to be completed in 2021.

  • Stay Alert! Expect the unexpected.
  • Watch for workers. Drive with caution.
  • Don't change lanes unnecessarily.
  • Avoid using mobile devices such as phones while driving in work zones.
  • Turn on headlights so that workers and other drivers can see you.
  • Be especially alert at night while driving in work zones.

To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project takes a systematic statewide approach to safety combining the benefits of CDOT’s programs that address driving behavior, our built environment and the organization's operations. The goal is to improve the safety of Colorado's transportation network by reducing the rate and severity of crashes and improving safety conditions for those traveling by all transportation modes. The program has one simple mission: to get everyone home safely.
