Highway construction

On Thursday, July 7, 9 p.m. to Friday, July 8, 5 a.m., the Colorado Department of Transportation and the I-25 North Express Lanes Project will close the southbound I-25 on- and off-ramps at Colorado Highway 56 to shift southbound I-25 traffic to a new alignment.

This closure will allow crews to complete work on the new ramps of the improved interchange, which will enhance motorist safety and efficiency once completed.

Motorists are asked to adhere to the following posted detour signage in the area:

  • Southbound traffic exiting I-25 will continue south to exit 245 at Weld County Road 34/Mead, turn around and travel north to exit 250.

  • Traffic intending to travel southbound on I-25 will travel north to exit 252 at Colorado Highway 60/Johnstown, turn around and re-enter southbound I-25.

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.
