Travel Impacts

Motorists can expect the following impacts:

  • Temporary closure of WCR 34 over I-25, Wednesday, May 7 at 9 p.m. to Friday, June 13 at 5 p.m.
  • Northbound I-25 on- and off-ramp closures at WCR 34, Thursday, May 8 at 5 a.m. to Friday, May 23 at noon.
  • Full closure of the I-25 East Frontage Road, north and south of WCR 34, Thursday, May 8 at 5 a.m. to Friday, May 23 at noon.
  • Southbound I-25 on- and off-ramp closures at WCR 34, Tuesday, May 17 at 5 a.m. to Friday, June 13 at 5 p.m.

This work is part of the I-25 North Express Lanes Project, Mead to Berthoud, which includes reconstruction and widening of bridges along this section of I-25. Full closures increase safety for the traveling public and crews while decreasing the duration of traffic impacts. Construction is weather-dependent and subject to change.

Please visit codot.gov/projects/north-i-25, for the most current travel updates. The I-25 North Express Lanes Project: Mead to Berthoud section 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.
