Full Closure Between McVicar and Howe Streets Begins Today
Sewer, Water, Road, and Sidewalk Reconstruction to Continue Through Fall
Motorists and Pedestrians Advised to Use Alternate Routes
Thunder Bay – May 27, 2025 – A major infrastructure overhaul has begun in the city’s north core, with the closure of Cumberland Street from McVicar Street to Howe Street starting today. The project, led by the City of Thunder Bay, includes the construction of a new roundabout at Cumberland and Water Street, aimed at improving traffic flow and safety in this key corridor.
The work marks a significant phase in long-term improvements to Thunder Bay’s road and utility networks. The closure will remain in place through the fall of 2025 to allow for the full replacement of sewer and water infrastructure, as well as complete road and sidewalk reconstruction.
Access and Detours
While Water Street remains open, all vehicle and pedestrian access is restricted within the construction zone on Cumberland Street. Motorists and pedestrians are urged to use alternate routes and to follow posted signage and detours.
As construction progresses, the closure will expand south to Villa Street, and later to Tupper Street. The City has committed to providing updated public notices at each stage to ensure residents and businesses are kept informed.
Investing in Infrastructure
The roundabout project is part of a broader commitment by the City to modernize aging infrastructure and enhance road safety. Once completed, the redesigned intersection is expected to improve traffic efficiency and support future development in the area.
“The City recognizes that construction impacts can be inconvenient,” according to a release from the COTB. “But these improvements are essential for long-term reliability and growth. We appreciate the public’s patience and cooperation.”
