Construction of the I-25 North Express Lanes from Johnstown to Fort Collins is underway with the full closure of the East Frontage Road between Colorado Highway 392 and Crossroads Boulevard.  Tolls will be set closer to the opening in 2021

Starting Sunday, crews will begin construction on mainline I-25 between Crossroads Boulevard and Kechter Road. Construction will be in two phases: full-width northbound followed by full-width southbound. While most of the work will be done off the road, some nighttime lane closures will be necessary.
