120-day closure of CO 402 at I-25 scheduled for next Monday

June 18, 2019 - Northeastern Colorado

LOVELAND - Beginning the night of June 24 through Oct. 22, Colorado Highway 402 will be fully closed under I-25 to allow for reconstruction of the interchange.

When completed on Oct. 22, the I-25 and CO 402 interchange will have undergone substantial changes, resulting in a new and improved interchange. Reconstruction will improve the safety for the travelling public on I-25 by smoothing out the curve, adding pedestrian and bike facilities to allow safe crossings of I-25, accommodating the continuing population growth in the Loveland and Johnstown area and modernizing the aging infrastructure as part of the Whole System – Whole Safety initiative. The new configuration at CO 402 will be fully operational by the end of October 2019, and future impacts at this interchange will be minimal.

Here are two artist renderings of what the interchange will look like on Oct. 22:

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.


The following tips are to help you stay safe while traveling through maintenance and construction work zones.

  • Do not speed in work zones. Obey the posted speed limits.

  • 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.

  • Expect delays, especially during peak travel times.

  • Allow ample space between you and the car in front of you.

  • Anticipate lane shifts and merge when directed to do so.

  • Be patient!


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 behaviors, 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 the safety of all transportation modes. The program has one simple mission—to get everyone home safely.


CDOT has approximately 3,000 employees located throughout Colorado and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated interregional express service. Gov. Polis has charged CDOT to further build on the state’s intermodal mobility options.
