Additional Closures:

I-25 and CO 7 Interim Mobility Hub Project

As part of the Colorado Department of Transportation’s Interstate 25 and Colorado Highway 7 Interim Mobility Hub project, I-25 will have the following overnight closures to install concrete girders for the new pedestrian bridge:

  • Northbound I-25 at CO 7 – Monday, Dec. 8, 8 p.m. to 5 a.m.
  • Southbound I-25 at CO 7 – Tuesday, Dec. 9, 8 p.m. to 5 a.m.

Drivers can expect a single lane closure at 8 p.m., a double lane closure at 9 p.m., and a full closure of I-25 at 11 p.m. on both nights. Traffic then will detour around the closure via the Highway 7 exit and entrance ramps (Exit 229). Slower traffic and delays should be expected.

Traffic control personnel will be present to manage traffic flow and maintain safety on the ramps and CO 7. All lanes will reopen to traffic by 5 a.m. 

For additional information about this project, contact the project team. 

A temporary closure of Valley Road is ongoing to allow crews to reconstruct the bridge over the road. This closure will be in place through 2025. Motorists should plan accordingly, as no detour route is available.

Southbound I-25 traffic shifted to the northbound lanes between Colorado Highway 56 and Colorado Highway 66 into a head-to-head configuration and will be in place through 2025.

I-25 North Express Lanes Closure

Approximately one mile of the southbound I-25 Express Lane, between mile points 251 and 250, from approximately Weld County Road 44 to Weld County Road 46, is closed through late 2027.

I-25 North Express Lanes: Open for testing!

The I-25 North Express Lanes, Berthoud to Fort Collins, opened in December 2023 and finalized finishing touches in the spring of 2024.

Since then, the Express Lanes have been open for use in a testing phase, allowing drivers to take advantage of the new Express Lanes, without paying a toll.

The Express Lanes are currently anticipated to begin tolling in early 2026. Once tolling begins in 2026, motorists are encouraged to sign up for an ExpressToll account to save an average of 40% on tolls.

For future project updates and information, please continue to check the project website and CoTrip.org.

Drivers are encouraged to try the Express Lanes by entering through the dashed white lines. When using the lanes, drivers are reminded to follow these rules to ensure the safety of everyone on the
road:

  • Do not cross the solid white lines (tickets for violations start at $75 each).
  • Enter and exit at the designated areas only, which are marked with a white dotted line.
  • Obey posted speed limits. The Express Lanes cannot be used to pass slower moving vehicles.
