Weld County Road 32 Closures
- Closures of Weld County Road 32 under I-25 will continue through March 27 because of various work activities.
The Town of Mead has closed WCR 32 under I-25 through Saturday, Feb. 21 for a water line installation. For more information on that closure, go to townofmead.org/engineering/page/street-maintenanceroad-closures-0
Temporary full closures of WCR 32 under I-25 are also planned to start Monday, Feb. 23 through Friday, March 27, 7 a.m. to 5 p.m. daily, Monday through Friday, for column and pier cap construction for the bridge. The road will be open to thru traffic at night and on weekends.
All work is weather dependent. The detours for these closures are:
- Eastbound WCR 32 traffic will take Weld County Road 7 south to Colorado Highway 66, turn east to Weld County Road 9.5, and turn north to WCR 32.
- Westbound WCR 32 traffic will take WCR 9.5 south to CO 66, turn west to WCR 7, and turn north to WCR 32.
There is an ongoing temporary full closure of Valley Road under I-25 through Tuesday at 5 p.m. to allow crews to demolish the existing bridge over the road.
Sunday through Tuesday, 9 p.m. to 5 a.m., there will be a southbound I-25 Express Lane and left lane closure between Colorado Highway 60 and Colorado Highway 56 for sign installation.
Monday through Saturday, 7 a.m. to 5 p.m., there will be alternating I-25 E. Frontage Road lane closures controlled by flaggers between Weld County Road 36 and Weld County Road 38 to allow crews to install drainage pipe across the road.
Monday and Tuesday, 9 p.m. to 5 a.m., there will be a southbound I-25 right lane closure between Weld County Road 34 and CO 66 for light pole and traffic camera installation.
Wednesday and Thursday, 9 p.m. to 5 a.m., there will be a southbound I-25 right lane closure between Weld County Road 40 and WCR 32 for lighting installation under bridges.
Thursday, 9 p.m. to 5 a.m., there will be a southbound I-25 on-ramp closure at CO 56 to allow crews to repair guard rails near the road.
- Traffic on CO 56 intending to travel south will turn north to CO 60/Weld County Road 48 (exit 252), turn around and enter southbound I-25.
I-25 E. Frontage Road Access Impacts:
The I-25 E. Frontage Road is temporarily closed to thru traffic between WCR 32 and CO 56 to prepare for the I-25 northbound lane widening and the frontage roadway transition. Crews demolished the WCR 32 bridge and will reduce the asphalt roadway width on isolated sections of the frontage road. Viable detour routes and speed limit reductions will be posted. Please drive carefully through the work zones and reduced roadway sections. Motorists may use alternate north/south roadways such as WCR 9.5, WCR 7 and Colorado Boulevard.
CDOT changed I-25 E. Frontage Road thru access north of WCR 34, near Mead, in January. Closing frontage road access to WCR 34 is required for crews to extend the North Creek Box Culvert as part of the I-25 North Express Lanes Project. This access change is part of CDOT’s continued coordination with the Town of Mead and Weld County, who are building a 2-mile portion of High Plains Boulevard between WCR 32 and WCR 36.
Once opened (projected summer 2026), traffic that previously used the frontage road will use High Plains Boulevard, and the frontage road use will transition to private property and utility access only. As shown on the map, local motorists will be able to access their properties between WCR 34 and WCR 36, but thru traffic will not be allowed. Similarly, local motorists will be able to access their properties between WCR 34 and WCR 32, but no thru traffic will be allowed.
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 I-25 North Express Lanes, Berthoud to Fort Collins, opened in December 2023 and finalized finishing touches in the spring of 2024.
Since then, the Express Lanes have been open for use in a testing phase, allowing drivers to take advantage of the new Express Lanes, without paying a toll.
The Express Lanes are currently anticipated to begin tolling in early 2026. Once tolling begins in 2026, motorists are encouraged to sign up for an ExpressToll account to save an average of 40% on tolls.
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.
No major traffic impacts this week.
