Billings Public Works will close Zimmerman Trail between Rimrock Road and Highway 3 beginning November 9 at 8:30 am. The closure is expected to last through November 30 as crews perform rock underpinning work.
Why it matters
The closure is necessary to complete the W.O. 26-34: Zimmerman Rock Underpinning project to stabilize the area. Drivers who rely on this route will need to navigate detours throughout the month.
The three-week closure will impact a route used by over 13,000 drivers daily. Commuters should prepare for an additional five minutes of travel time on their alternate routes during the project.
The players
Billings Public Works
This municipal department manages infrastructure projects, road maintenance, and utility operations for the city of Billings.
The details
Contractors are tasked with anchoring and stabilizing a section of rock by underpinning it to ensure safety. The construction timeline includes the Thanksgiving holiday period, meaning the road will remain inaccessible for the duration of the work.
Timeline
The Zimmerman Trail closure begins November 9, 2026, at 8:30 am.
The road will remain closed throughout the November 2026 Thanksgiving holiday.
Construction work is expected to conclude on November 30, 2026.
Market Landscape
This project aligns with the Federal Highway Administration's safety inspection mandates that prioritize public infrastructure stability. Such maintenance programs are standard for regional governments managing high-traffic corridors against natural erosion and rock instability.
Drivers who use this route daily must account for at least five extra minutes of travel time during their commute. Residents should plan for potential traffic delays on surrounding streets while Zimmerman Trail is closed.
The takeaway
Commuters should adjust their schedules in advance to accommodate the detour and construction timeline. Planning for the additional five-minute commute will help minimize disruptions during the three-week closure.
What happens next
The construction project is scheduled to reach completion on November 30, 2026.
