LOVELAND – The I-25 North Express Lanes Project team will close southbound I-25 between Crossroads Boulevard and US 34 to place girders on the I-25 bridge over the Union Pacific Railroad tracks from 11 p.m., Friday, Feb. 28, until 6 a.m., Saturday, Feb. 29 and again from 10 p.m., Saturday, Feb. 29, until 5 a.m., Sunday, March 1. 

Crews will also close the northbound I-25 left lane from 8 p.m., Friday, Feb. 28, until 5 a.m., Saturday, Feb. 29 and again from 8 p.m., Saturday, Feb. 29, until 5 a.m., Sunday, March 1.

Detour for the closure: 

Southbound I-25 traffic will be detoured off I-25 at Crossroads Boulevard, then east to Centerra Parkway, and south on Centerra Parkway to US 34 and west to I-25.  

CDOT’s commitment to highway safety, through their Whole System Whole Safety initiative, deems this closure 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.

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.
