Larimer and Weld Counties — Starting July 13 at 4 a.m. to July 14 at 5 p.m., the Colorado Department of Transportation (CDOT) will temporarily close Larimer County Road 16 under I-25 to pour the new concrete bridge deck and install a drainage pipe crossing. Detours will be in place. Motorists may use East County Road 14 or East County Road 18 as alternative routes.

An additional full closure of the southbound I-25 off-ramp to Colorado Highway 60 will take place on July 16 at 9 p.m. to July 17 at midnight for drainage pipe installation. The Frontage Road will be open and can be accessed from Larimer County Road 5. Detours will be in place on Weld County Road 44 to access east of I-25.

About 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 2024.
