Construction Activities & Impacts
Work this Week | Nov. 9 to Nov. 15
Lane closures for the week of Nov. 9:
-
Sunday through Wednesday: Full closure of southbound I-25 off-ramp at WCR 34.

Sunday, Nov. 2 at 12 a.m., to Wednesday, Nov. 12 at 5 a.m., there will be a temporary full closure of the southbound I-25 off-ramp at Weld County Road 34 to allow crews to rebuild the ramp and join it with the new concrete lanes of I-25. This closure is planned to end on Wednesday, November 12 at 5 a.m.
- Traffic intending to exit southbound I-25 at WCR 34 will continue south to exit at Colorado Highway 66, then travel back north onto I-25 and exit at WCR 34.
Tuesday, 9 p.m. to 5 a.m., there will be a southbound I-25 right lane closure between CO 66 and Weld County Road 32 and CO 66 for lane striping operations.
Monday, Nov. 17, 9 p.m. to 5 a.m., there will be a temporary full closure of the southbound I-25 on-ramp at WCR 34 to allow crews to install lighting caissons.

Permanent Frontage Road Closure
CDOT is actively coordinating with the Town of Mead and Weld County on the High Plains Boulevard Project while continuing construction on this segment of the I-25 North Express Lanes Project.
As part of this coordination, the I-25 E. Frontage Road, between WCR 34 and Weld County Road 36, will close permanently on Monday, Dec. 1, to allow for the expansion and additional lanes on I-25 North. Once the frontage road is closed, it will only be open to local business traffic. Local business access will also be available from WCR 36 and Weld County Road 38.
However, once the new High Plains Boulevard is complete, previous frontage road traffic, including local business traffic, will shift onto the newly constructed High Plains Boulevard.
Ongoing 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 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.
