Lane closures for the week of Jan. 26:
- Monday through Saturday: Alternating traffic with flaggers on WCR 34, west of I-25.
- Monday through Saturday: Intermittent closures with flaggers on southbound I-25 on-ramp to WCR 34.

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.
Monday through Saturday, 7 a.m. to 5 p.m., Weld County Road 34 will be reduced to one alternating lane, controlled by flaggers, west of I-25 for dirt hauling operations.
Monday through Saturday, 7 a.m. to 5 p.m., the southbound I-25 on-ramp to WCR 34 will have brief intermittent closures, controlled by flaggers, for dirt hauling operations.
Monday through Saturday, 10 a.m. to 5 p.m., the East I-25 Frontage Road at Weld County Road 38 will be reduced to one alternating lane controlled by flaggers west of I-25 for dirt hauling operations.
Thursday night, Colorado State Patrol will have traffic-pacing operations on northbound and southbound I-25, between Colorado Highway 66 and Larimer County Road 16, to allow crews to lower electrical power lines over the highway at Weld County Road 38. Pacing will happen overnight, between 11 p.m. and 2 a.m., and will last approximately 20 minutes. The southbound I-25 on-ramps to CO 60, Weld County Road 56, and northbound I-25 on-ramps at WCR 34 will also be briefly closed while CSP passes by with paced traffic.
Monday, Feb. 3 through Thursday, Feb. 6, 7 a.m. to 5 p.m., Weld County Road 32 under I-25 is scheduled to be temporarily closed to allow crews to install new bridge caissons near the roadway.
- Westbound WCR 32 traffic will take the East I-25 Frontage Road south to Mulligan Street, turn east to County Road 9.5, turn south to CO 66, turn west to Weld County Road 7, and turn north to WCR 32.
- Eastbound WCR 32 traffic will take WCR 7 south to CO 66, turn east to WCR 9.5, and turn north to WCR 32.
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.
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.
