CDOT celebrates start of I-25 North Express Lanes: Mead to Berthoud

Travel Advisory

May 30, 2024 - Northeastern Colorado - The project ties the north I-25 corridor together

Weld County — The Colorado Department of Transportation held a groundbreaking ceremony to officially kick-off the next I-25 North Express Lanes Project segment, Mead to Berthoud.

“This six-mile project will expand and enhance I-25, from Colorado Highway 66 in Mead and connect to the newly built portion of I-25 just south of CO 56 in Berthoud — making travel safer, more reliable and efficient in northern Colorado,” said CDOT Northeast Colorado Regional Transportation Director Heather Paddock. “Once complete in 2028, this project will complete the last missing link on I-25 and will be the first time there will be more than two lanes of I-25 from Denver to Fort Collins in both directions.”

The event took place at the north end of the project limits – off of Colorado Highway 56 at I-25. Representatives from CDOT, the Federal Highway Administration and Colorado Senator Barb Kirkmeyer were in attendance and gave remarks to celebrate the start of the next improvements to I-25.

CDOT Executive Director Shoshana Lew talked about the importance of this partnership. “I would like to recognize all of the partnership to get this project moving quickly, and the incredible work of the CDOT Region 4 team, who have delivered many segments of this project efficiently and effectively. “This link will ensure a consistent ride for both drivers and Bustang, making mass transportation even more attractive to passengers and making Northern Colorado more attractive to people who work in Denver and beyond.”

The first phase of the project includes constructing additional width on the northbound inside shoulder. Drivers should anticipate increased construction activity in the area. Construction is expected to start in May and be complete by mid-2028. Ralph L. Wadsworth & SEMA Construction are the construction managers for this project.

State Senator Barb Kirkmeyer, who was on the Weld County Board of Commissioners when a lot of the planning for I-25 ramped up, is excited. “After 50 years and 4 million more people in Colorado, and with help from county and city leaders and the business community, Colorado’s Main Street – I-25 – gets a much needed ‘makeover’- finally,” she said.

During construction, two lanes of traffic on I-25 will be maintained in each direction during peak travel times, but drivers can expect overnight lane closures in the area. In addition, lane and shoulder widths will be minimized. The speed limit will be reduced. Please pay attention and follow posted speed limit signs.

“I'm thrilled to return to Colorado to celebrate the groundbreaking of Segment 5 of the I-25 Corridor project, a project that will benefit the region and nation," said Federal Highway Administrator Shailen Bhatt. "By eliminating the bottleneck between Mead and Berthoud and enhancing multimodal connections, we're advancing safety, trip reliability, freight efficiency, and reducing emissions.”

Mayor of Mead Colleen Witlow added what this project will mean for her community. “As the Mead Mayor and a proud member of the North I-25 Coalition for the past 10 years, I am not just a representative, but also a fellow community member who shares in your excitement and pride,” she said. “This segment is more than just a road improvement; it is a testament to our collective vision and shared purpose.”

What is the I-25 North Express Lanes Project, Mead to Berthoud?

This project on the I-25 North corridor is a continuation of the approximately 20 miles of improvements that have been completed on I-25 between Berthoud to Fort Collins over the past six years. This approximately six-mile project will expand and enhance I-25, from Colorado Highway 66 in Mead and connect to the newly built portion of I-25 just south of CO 56 in Berthoud. Once complete in 2028, this project will complete a major missing puzzle piece on I-25 and will be the first time there will be more than two lanes of I-25 from Denver to Fort Collins in both directions.

This project will:

  • Reduce congestion, vehicle accidents, fatalities and greenhouse gas emissions
  • Improve trip reliability and freight efficiency
  • Increase user choice by adding an Express Lane in both directions
  • Improve aging infrastructure

Specific corridor improvements include:

  • Widen the inside roadway shoulder to 10 feet and the outside roadway shoulder to 12 feet (both are currently 4-feet wide).
  • Fully reconstruct the I-25 and Weld County Road 34 interchange.
  • Fully reconstruct bridges along this section of I-25, including:
    • Weld County Road 32
    • Weld County Road 34
    • I-25 over Great Western Railway
    • Weld County Road 38
    • I-25 over Valley Road
  • Reconstruct I-25 to add one 12-foot Express Lane in each direction from CO 66 to just south of CO 56 with a 4-foot painted buffer separating the tolled Express Lane from the general purpose travel lanes.
  • Install and integrate tolling and Intelligent Transportation Systems equipment.
