LOVELAND The Colorado Department of Transportation will place deck panels on the new US Highway 34 bridge over I-25, which will require nighttime full closures of I-25 and US 34 next week. 

Deck panels on the new portion of the bridge will be placed Oct. 20 through 23.  

Once completed, the bridge will ease traffic congestion by adding an additional thru lane in each direction, reconfiguring the on- and off-ramps, and improving pedestrian access.


  • I-25 full closure at US 34 will take place from 9 p.m. to 5 a.m., Oct. 20 through Oct. 22. I-25 traffic will be detoured up and over I-25 on Exit 257/US 34.

  • US 34 full closure between the on- and off-ramps over I-25 from 9 p.m., Oct. 20, until 5 a.m., Oct. 21 and again from 9 p.m., Oct. 21, until 5 a.m., Oct. 22.

    • Westbound US 34 traffic will be detoured north on I-25 to Exit 259/ Crossroads Boulevard. Turn left on Crossroads Boulevard and then go south on I-25 to Exit 257/ US 34. 

    • Eastbound US 34 traffic will be detoured south on I-25 to Exit 255/ Colorado Highway 402. Turn left on CO 402 and go north on I-25 to Exit 257/ US 34.

  • Eastbound US 34 on-ramp to northbound I-25 full closure from 9 p.m. to 5 a.m., Oct. 20 through 23. 

    • Northbound I-25 on-ramp traffic from eastbound US 34 will be detoured east on US 34 to Centerra Parkway. Proceed north on Centerra Parkway to Crossroads Boulevard, go west on Crossroads Boulevard to the northbound I-25 on-ramp.

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.

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.

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.

  • Don’t drive distracted. Don’t use mobile devices such as phones while driving.

  • 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!


Safe transportation infrastructure is essential for emergency first responders and freight drivers as Colorado navigates the COVID-19 pandemic. With that in mind, 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 and practice social distancing, wear face masks, stay at home when possible, and avoid nonessential travel. With fewer vehicles on the roads, CDOT crews will be able to work more efficiently and safely.


In early 2019, CDOT announced its Whole System — Whole Safety initiative to heighten safety awareness. This initiative 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 inter-regional express service. Governor Jared Polis has charged CDOT to further build on the state’s multimodal mobility options.
