I-25 Mead to Berthoud .jpg

Communities along the I-25 North corridor are expanding rapidly, contributing to major economic growth in northern Colorado. CDOT is supporting this growth by delivering the continued expansion of I-25 North.

The I-25 North Express Lanes from Mead to Berthoud are 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. These 6 miles of Express Lanes will expand and enhance I-25, from Colorado Highway 66 in Mead and connect to the newly completed Express Lanes on I-25 just south of Colorado Highway 56 in Berthoud.

Improvements along this 6-mile stretch of Express Lanes include:

  • 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.
