CDOT will fully close CO 60 over I-25 and ramps for several nights this weekend

September 15, 2021 - Northeastern Colorado - Starting Sept. 18, CDOT will close several roadways to divert traffic onto the new CO 60 bridge.

Larimer and Weld Counties — Starting Saturday, Sept. 18, at 9 p.m. to Sunday, Sept. 19, at 9 p.m., the Colorado Department of Transportation will close the following roadways to divert traffic onto the newly built Colorado Highway 60 bridge:

  • Northbound I-25 on-ramp from CO 60 
  • Southbound I-25 off-ramp to CO 60 
  • CO 60 bridge over I-25 

The southbound I-25 on-ramp from CO 60 and the northbound I-25 off-ramp to CO 60 will remain open as part of the CO 56 detour.

There will be several overnight closures of I-25 at CO 60 throughout the week of Sept. 19 in order to demolish the aging concrete bridge. Traffic will be diverted up and over the I-25 ramps at CO 60. The CO 60 bridge over I-25 will also be closed during those times. 

The closures are part of the I-25 North Express Lanes Berthoud to Johnstown Project.

Please visit 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 segment is expected to be complete in 2023.
