CDOT will host virtual public meeting to discuss upcoming 21-day closure of CO 60 at I-25 on Aug. 22

News Release

August 17, 2022 - Northeastern Colorado - Join the meeting for upcoming project changes between Berthoud and Johnstown

Weld County - The I-25 North Project team will host a virtual public meeting on Monday, Aug. 22, 6 – 7 p.m., to inform communities, property owners and drivers along the corridor about the upcoming work that includes a 21-day closure of Colorado Highway 60 over I-25 that starts on Sept. 12.

At the meeting, the team will discuss this closure and its detour route, as well as preview upcoming work on the project.

Meeting details are as follows:

  • Registration is required to attend
  • Day: Monday, Aug. 22, 2022
  • Time: 6 – 7 p.m.
  • Online via Zoom

This east/west closure of the CO 60 portion over I-25 is necessary for motorist and worker safety to reconfigure lane alignments into the Diverging Diamond Interchange (DDI) and tie it into the rest of CO 60. Work will also include installing drainage pipes, curb and gutter work, traffic signals and striping. In addition, there will be intermittent CO 60 ramp closures during the 21-day period.

The CO 60 DDI is one of just a handful of such interchanges in Colorado. The DDI crosses traffic to the opposite side of the road across an interchange so vehicles have unimpeded movements onto the freeway ramps. Left-turn movements, which are a typical challenge with standard four-way interchanges, do not have to cross oncoming traffic in a DDI, helping traffic move more smoothly and increasing safety. Drivers can view a video on how to drive a DDI on YouTube.

During the closure, which is necessary to put the new alignment in place, east/west access over I-25 on CO 60 will not be allowed with additional intermittent ramp closures. The detours will change as construction progresses, but detour routes will be available from I-25 to the Colorado Highway 402 and Colorado Highway 56 interchanges, as well as the Larimer County 16 exits.

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.
