The speed limit will be lowered as needed on the project to 65 mph. Please obey speed limit signs.
Sunday, 9 p.m. to 5 a.m., there will be a northbound I-25 left lane closure between Weld
County Road 36 and Weld County Road 38 to allow crews to shift safety barriers.
Monday, 9 p.m. to 5 a.m., there will be a northbound I-25 right lane closure and shift
between WCR 36 and WCR 38 for a traffic switch to a new lane alignment.
Tuesday through Thursday, 9 p.m. to 5 a.m., there will be a southbound I-25 left lane closure between the Little Thompson River and Weld County Road 34 to allow crews to shift safety barriers.
Thursday, 7 a.m. to 5 p.m., the I-25 SE Frontage Road at Colorado Highway 402 will be
reduced to one lane of alternating traffic, controlled by flaggers, for grading work near
guardrail.
Friday, 9 p.m. to 5 a.m., the southbound I-25 Express Lane and left lane between the Little Thompson River and WCR 34 will be closed, as well as the southbound I-25 on-ramp at Colorado Highway 56 to allow crews to stripe lanes, move barriers and switch traffic onto new lanes.
- Traffic on CO 56 intending to travel south will turn north to Colorado Highway 60, turn around and enter southbound I-25.
The southbound I-25 Express Lane between CO 60 and CO 56 will close on Friday, Nov. 22, at 9 p.m. This will remain closed through late 2027. The closure is required for crews to perform work needed during the various phases of the I-25 North Express Lanes, Mead to Berthoud project. Work includes concrete paving in both directions of I-25, reconstructing the I-25 interchange at WCR 34, as well as five other bridges, and adding one 12-foot Express Lane in each direction from CO 66 to CO 56.
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.
