Construction Activities & Impacts
Work this Week | May 25 to May 31
Lane closures for the week of May 25:
- Ongoing: Full closure of WCR 34 over I-25 through June 18.
- Tuesday: Ongoing full closure of southbound I-25 on- and off-ramps at WCR 34 through June 18.
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.
The speed limit on the project has been lowered to 65 mph. Please obey speed limit signs.
A temporary closure of Weld County Road 34 over I-25 is ongoing through Wednesday, June 18 at 5 p.m. This closure will allow crews to pour concrete pavement, complete the new WCR 34 overpass, and perform ramp and future intersection earthwork as construction progresses. Detours for this closure will change as work progresses.

Additional Closures:
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 Summer 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.
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.
As of Friday, Dec. 15, 2023, the I-25 North Express Lanes, Berthoud to Fort Collins, hit a major milestone and is now substantially complete.
While most of the work in this section of I-25 is done, CDOT and the contractors will have various intermittent lane closures through spring 2024 to finish final project punch list tasks. The Express Lanes are now open for testing, but drivers should also prepare for intermittent closures of these lanes in 2024. Express Lane tolls are waived during the testing phase.
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.
Motorists should expect various overnight and lane closures, including in the Express Lanes, while the last of the construction wraps up and tolling equipment is installed. The Express Lanes are anticipated to begin tolling in 2024. Once tolling begins in 2024, motorists are encouraged to sign up for an ExpressToll account to save an average of 40% on tolls.
