Southbound I-25 nighttime closure needed on Nov. 17 between Loveland and Berthoud for a traffic shift

Travel Advisory

November 15, 2023 - Northeastern Colorado - Detours will be in place west of I-25

Larimer and Weld Counties — The Colorado Department of Transportation will close southbound Interstate 25 between Colorado Highway 402 and Colorado Highway 56 from 9 p.m. to 5 a.m. on Friday, Nov. 17, to allow crews to place permanent striping for a traffic shift to the final lane alignment.

In addition, the southbound I-25 on-ramp at Colorado Highway 60 (exit 252) will be closed during this time as part of the striping and traffic shift. Full closures decrease the duration of traffic impacts and increase safety for the traveling public and crews.

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 segment is expected to be complete in early 2024.
