Traffic Impacts
Construction Activities & Impacts
Work this Week | Nov. 2 to Nov. 8
Lane closures for the week of Nov. 2:
- Sunday: Early morning southbound I-25 on-ramp closure at WCR 34.
- Sunday: Early morning southbound I-25 right lane closure at WCR 34.
- Ongoing through Friday: Full closure of WCR 38 over I-25.
- Monday through Nov. 12: Full closure of southbound I-25 off-ramp to WCR 34.
The speed limit on the project has been lowered to 65 mph. Please obey speed limit signs. Sunday morning, 12 a.m. to 5 a.m., there will be a temporary full closure of the southbound I-25 on-ramp from Weld County Road 34 to allow crews to perform a traffic switch and open the new on-ramp. There will also be a southbound I-25 right lane closure at WCR 34 from 9 p.m. to 5 a.m.
- Traffic on WCR 34 intending to enter southbound I-25 will travel north to Colorado Highway 56 (exit 250), turn around and enter southbound I-25.
Starting Monday at 4 a.m., there will be a temporary full closure of the southbound I-25 off- ramp to WCR 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, Nov. 12 at 5 a.m.
- Traffic intending to exit 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.
Weld County Road 38 over I-25
The full closure of Weld County Road 38 over I-25, east of Mead, to allow crews to reconstruct the bridge over the highway is planned to reopen on Friday, Nov. 7 at 5 p.m. Until then, detours will remain in place:
- Eastbound WCR 38 traffic will take Weld County Road 7 south to WCR 34, turn east to the I-25 E. Frontage Road and turn north to WCR 38.
- Westbound WCR 38 traffic will take the I-25 E. Frontage Road south to WCR 34, turn west to WCR 7, and turn north to WCR 38.
The aging WCR 38 bridge was built in 1960 and needed safety and traffic capacity improvements, and a larger bridge was needed to span the widened I-25 section. Since closing the bridge in June, crews transformed the WCR 38 bridge over I-25 with the following work:
- Demolished the previous bridge
- Completely reconstructed a new bridge
- Constructed a new 8-foot-wide sidewalk on the bridge for multimodal connections over I-25
- Connected the new WCR 38 bridge to the roadway
Ultimately, this closure helped invest money into permanent infrastructure in another area of the project and saved Colorado taxpayer money. Completing the reconstruction of this bridge is a major milestone, bringing the project one step closer to the finish line for a safer, more efficient I-25 North corridor.
Additional 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 Summer 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.
