I-25 North Express Lanes - Mead to Fort Collins

About the Project:

Access Detailed Traffic Impacts for the I-25 North Express Lanes Project for the week of Feb. 25

Communities along the I-25 North corridor are expanding rapidly, contributing to major economic growth in northern Colorado. The Colorado Department of Transportation is supporting this growth by delivering the expansion of I-25 North. Improvements are currently underway along I-25 between Berthoud and Fort Collins (with more to come from Mead to Berthoud), including:

  • Construction of northbound and southbound Express Lanes with HOV option from CO 56 to just past Prospect Road.
  • New interchange construction with lengthened bridges to accommodate additional I-25 lanes at Prospect Road, US 34, CO 402, CO 60, CO 56, and Weld County Road 34.
  • Reconstruction of the Great Western Railroad bridges, bridges over the Cache la Poudre river, Hillsboro Frontage Road bridge, Little Thompson River bridges, Big Thompson River bridges, and Larimer County Road 20.
  • Reconstruction of the Port of Entry 2,000 feet south of current location for improved interstate operations.
  • Operational improvements of on– and off-ramps at Harmony Road.
  • Replacement of the Kechter Road bridge and elevation of the I-25 crossing at Kechter to rebuild to city standards.
  • New mobility hub with center lane bus slip ramps for Bustang, expanded Park-n-Ride lot, and creation of a new pedestrian and bicycle access under I-25 at Kendall Parkway.
  • Frontage Road improvements at CO 402 and CO 56, addition of roundabouts, and relocation and widening of the current Park-n-Rides.
