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 Friday, 7 a.m. to 5 p.m., Weld County Road 38, west of I-25, will have brief, intermittent closures controlled by flaggers to allow truck access for dirt hauling.
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.
Monday through Friday, 7 a.m. to 5 p.m., Weld County Road 32, under I-25 east of Mead, will be closed to allow crews to install new bridge girders over the roadway. Detours will be in place:
- 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 Colorado Highway 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.
Tuesday, midnight to 5 a.m., there will be a full closure of I-25 under Weld County Road 34 to allow crews to pour a new concrete bridge deck. In addition, eastbound and westbound WCR 34 will be closed. In case of weather or other impacts, a contingency night will be scheduled. Detours will be in place:
- North- and southbound I-25 traffic will be rerouted using the off- and on-ramps at WCR 34 (mile point 245). No turning movements will be allowed on or off WCR 34 during this time.
- Eastbound WCR 34 traffic will turn south on County Road 7, turn east on CO 66, and turn north on Colorado Boulevard to WCR 34.
- Westbound WCR 34 traffic will turn south on Colorado Boulevard, turn west on CO 66, and turn north on CR 7 to WCR 34.
- For I-25 access to WCR 34, traffic will be directed to the I-25 and CO 66 interchange and follow other routes to the east or west.
Tuesday, 7 a.m. to noon, the southbound I-25 on-ramp at WCR 34 will have intermittent closures controlled by flaggers to allow crews to complete work on the new concrete bridge deck.
Additional Closures:
Due to supplier issues, the southbound I-25 on-ramp closure at WCR 34 has been rescheduled to Friday, April 25 at 9 p.m. through Saturday, April 26 at 5 p.m. for pipe installation and asphalt work. A detour will be in place:
- Traffic on WCR 34 intending to travel south will turn north to Colorado Highway 56/Weld County Road 44 (exit 250), turn around and enter southbound I-25.
Southbound I-25 traffic shifted to the northbound lanes between CO 56 and CO 66 into a head-to-head configuration and will be in place through 2025.
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.
