January 8, 2020 - Northeastern Colorado

LARIMER/WELD — The Colorado Department of Transportation continues construction on I-25 between Colorado Highway 60 and US Highway 34. During nighttime hours on Monday, a full closure of I-25 will be required, and CO 60 over I-25 will be closed during nighttime hours on Wednesday.

On Monday, necessary project maintenance will require a full closure of northbound I-25 between Colorado Highway 402 and US 34 from 9 p.m., Monday, until 5 a.m., Tuesday. Northbound traffic will exit I-25 at Exit 255/CO 402, head east to County Road 13, proceed north on County Road 13 to US 34 and west on US 34 to the northbound I-25 on-ramp.

On Wednesday, the CO 60 bridge over I-25 will be closed between midnight and 4 a.m. to allow for the removal of guardrail, installation of concrete barriers and roadway striping. CO 60 east- and westbound traffic will be detoured north on I-25 to CO 402 or south on I-25 to Colorado Highway 56. The frontage road closure between CO 56 and Weld County Road 46 will remain in effect.

Please follow posted signage in the area and plan accordingly. Construction is weather-dependent and subject to change.

Whole System. Whole Safety. 

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.     

About CDOT

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.  


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 measures to reduce COVID-19 exposure on the worksite. The Colorado Department of Public Health and the Environment has promulgated guidelines for construction activities. Gov. Polis announced an emergency, temporary stay-at-home order for all of Colorado, which went into effect Thursday March 26. With this order, the public is urged to #DoYourPartCO and avoid all nonessential travel. With fewer vehicles on the roads, CDOT crews will be able to work more efficiently and safely.
