Projects

Crews have begun construction of the I-25 North Express Lanes, Mead to Berthoud, as of Sunday, May 12, 2024.

Community members are encouraged to watch the presentation video and submit any feedback or questions to the project team at northi25expresslanes@gmail.com.

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 6-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.

• Widen the inside roadway shoulder to 10 feet and the outside roadway shoulder to 12 feet.
• 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.
