CDOT hosts virtual public meeting June 29 for 140-day closure of CO 56 over I-25

News Release

June 22, 2021 - Northeastern Colorado - Join the meeting to learn more about the closure later this summer and early fall

WELD COUNTY — The I-25 North Express Lanes project between Berthoud and Johnstown will enter a new phase of construction later this summer and early fall. The project team will host a virtual public meeting on June 29, 6–7 p.m., to inform communities, property owners and drivers along the corridor about an upcoming full closure of Colorado Highway 56 over I-25 for no more than 140 days. 

This virtual public meeting will be an online webinar. Attendees will log online through the Zoom meeting link below and follow along with the presentation. Registration is required to attend. The webinar setup will also give community members the opportunity to submit questions and concerns to be answered along the way by the project team as they would in an in-person meeting. 

The full closure of CO 56 is required in order for crews to safely and efficiently reconstruct the interchange into a new configuration. While the roadway is closed, construction crews will flip the interchange so that I-25 runs over CO 56, instead of under it, as it is currently. The new configuration will correct unsafe curves that will provide a safer traveling experience while also helping the interstate operate more efficiently. When complete, the interchange will also include two new roundabouts at the northbound and southbound ramps, and the carpool lot will be relocated to the northeast corner of the interchange. CDOT and its Contractor will present more construction details, review detour routes and answer any questions from the community in this virtual public meeting. 

A recording of the meeting will be posted on our website (listed below) after the meeting for those who were unable to attend. 

Meeting details are as follows: 

  • Day: Tuesday, June 29, 2021
  • Time: 6 – 7 p.m.
  • Location: By phone via 929-436-2866
  • Meeting ID: 885 1272 1318

About I-25 North Express Lanes: Berthoud to Fort Collins

The I-25 North Express Lanes Project 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 two mobility hub transit facilities. During construction on the I-25 North Express Lanes Project, motorists should expect speed reductions to 55 or 65 mph, minor lane shifts, temporary concrete barriers and median bridge work. Motorists should also expect delays during the scheduled work hours. Construction is expected to be complete in early 2024.
