I-25 North Express Lanes Berthoud to Fort Collins will have upcoming closures

May 13, 2021 - Northeastern Colorado

WELD COUNTY — Starting May 16 to June 3, the I-25 North Express Lanes Project will require multiple closures due to progression of the project toward creating an Express Lane in each direction from Berthoud to Fort Collins. 

  • From May 16 at 9 p.m. to May 23 at 5 a.m., there will be a full closure of eastbound and westbound Larimer County Road 14 to install the new bridge girders for the southbound I-25 bridge over LCR 14 and to reconstruct LCR 14 under I-25. A detour will be in place. Drivers will detour on the frontage roads to Larimer County Road 16.

  • On May 24 at midnight, the frontage road between Colorado Highway 60 and LCR 14 will close permanently as part of the new widening of I-25. Continued use of alternate routes will be required. Due to construction and ongoing phasing of the I-25 North Express Lanes project, the frontage road will be closed while phases of the parallel arterial, the new High Plains Boulevard, are constructed. Connecting LCR 14 to High Plains Boulevard is anticipated for completion by the end of the project in 2023. For more information on the Frontage Road closures and High Plains Boulevard, go to www.codot.gov/projects/north-i-25/johnstown-to-fort-collins/assets/i-25n_frontagerds_factsheet_210104.pdf/.

  • Starting May 16 at 9 p.m. to May 17 at 5 a.m., there will be a full closure of eastbound and westbound LCR 16 to install new bridge girders. Drivers will detour on the Frontage Roads to Larimer County Road 18 or LCR 14. 

  • Starting May 17 to June 3, there will be intermittent nightly single lane closures from 9 p.m. to 5 a.m. on LCR 16 to install deck panels over LCR 16.

Please visit www.codot.gov/projects/north-i-25, for the most current travel updates. The I-25 North Express Lanes Project: Berthoud to Johnstown section will increase highway capacity by adding an Express Lane in each direction, rebuild interchanges, replace aging bridges, straighten highway curves to improve safety, make major utility and drainage improvements, and add carpool and transit facilities. During construction on the I-25 North Express Lanes Project, motorists should expect speed reductions to 65 mph, minor lane shifts, temporary concrete barriers and median bridge work. Motorists should also expect delays during the scheduled work hours. Construction on the Berthoud to Johnstown piece is expected to be complete in 2023.
