The Pacific Avenue Overpass will be closed for the duration of the 2026 construction season starting on Monday, June 29 to allow for major rehabilitation work on this important transportation corridor.

During the closure, motorists will be detoured via the Main Street Bridge and Island Drive. Pedestrians can use the East End pedestrian underpass, located near the intersection of Simpson and Rowand streets. 

Regular security patrols of the pedestrian underpass will be in place for the duration of the project. Residents may report maintenance concerns at any time to the City’s 24/7 Dispatch line at 807-625-2195.

This closure will impact the 12–East End Thunder Bay Transit route. Transit users are encouraged to visit thunderbay.ca/Transit for route details and service updates.

The overpass is expected to reopen to traffic in November. Additional closures will be required in Spring/Summer 2027 to complete rehabilitation work.

Planned work includes significant concrete repairs to the deck, barriers, and piers, replacement of the structure’s centre span, and repair and replacements of the bearings.

This project prioritizes reinvestment in existing infrastructure, maintains a state of good repair, and optimizes the performance of the transportation network. Renewing key connections like the Pacific Avenue Overpass supports safe, reliable mobility between neighbourhoods and helps ensure infrastructure is well positioned to support Thunder Bay’s long-term growth.
