Work this Week
Dec. 1 to Dec. 7
Lane closures for the week of Dec. 1:
- Ongoing: Southbound I-25 Express Lane closure between MP 251 and 250.
- Ongoing: Southbound I-25 lanes shifted to northbound side between CO 56 and CO 66.
The speed limit on the project has been lowered to 65 mph. Please obey speed limit signs.
Approximately one mile of the southbound I-25 Express Lane, between mile points 251
and 250, is closed through late 2027.
Also, southbound I-25 traffic has been 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. These closures are required for crews to perform work needed during the various phases of the I-25 North Express Lanes, Mead to Berthoud project.
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.
No major traffic impacts this week.
Segments 6, 7 and 8 have reached substantial completion and will have intermittent lane and ramp closures through spring.
