News Release

May 7, 2020 - Northeastern Colorado

LOVELAND The I-25 North Express Lanes Project will require full closures of I-25 at US 34 and of US 34 over I-25 in order to remove the steel beams on US 34 and begin the new bridge construction. This operation will take place 9 p.m. on May 13 until 5 a.m. May 14 and again from 9 p.m. on May 14 until 5 a.m. on May 15.

Detour Information

Northbound and southbound I-25 traffic will exit I-25 at US 34, continue through the traffic signal onto temporary detour pavement and back onto I-25.

Eastbound US 34/northbound I-25 traffic from the west side of I-25 will detour on southbound I-25 to Colorado Highway 402, go east and continue onto northbound I-25 to US 34. Northbound I-25 traffic will continue through the traffic signal onto temporary detour pavement to northbound I-25. 

Westbound US 34/southbound I-25 traffic from the east side of I-25 will detour on northbound I-25 to Crossroads Boulevard, go west and continue onto southbound I-25 to US 34. Southbound I-25 traffic will continue through the traffic signal onto temporary detour pavement to southbound I-25. 

CDOT’s commitment to highway safety through their Whole System Whole Safety initiative deems these closures necessary to protect motorists from potential danger posed by overhead work and equipment staged on the roadway as they travel along I-25. 

Project Information 

The I-25 North Express Lanes: Johnstown to Fort Collins Project will increase capacity by adding an Express Lane in both directions, constructing inside and outside shoulders, and replacing aging 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, and improve interchanges at CO 402, Prospect Road and US 34.


Safe transportation infrastructure is essential for emergency first responders and freight drivers as Colorado navigates the COVID-19 pandemic. With that in mind, road maintenance and construction continues on CDOT projects with social distancing and other health safety measures to reduce COVID-19 exposure on the worksite. The Colorado Department of Public Health and Environment announced guidelines for construction activities. The public is urged to join the campaign for #DoingMyPartCO by practicing social distancing, wearing face masks, staying at home when possible, and avoiding nonessential travel. With fewer vehicles on the roads, CDOT crews will be able to work more efficiently and safely. 



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.
