August 7, 2026 – The City of Thunder Bay is sharing details of construction projects expected to impact vehicular, cycling, and pedestrian travel in the month of August.

The City is investing approximately $60 million in 2026 to maintain, improve, and expand Thunder Bay’s roads, bridges, sidewalks, trails, watermains, and other infrastructure that residents rely on every day.

This work helps move forward major initiatives in Thunder Bay’s Smart Growth Action Plan, including the revitalization of both downtown cores and the Reimagine Victoriaville project.

While it is essential to our community, this work can result in travel delays. The City aims to minimize disruption by sharing project details with the public in advance.

Residents can find more information, including a live construction project map and a list of all projects scheduled for 2026, at: thunderbay.ca/Construction

The City reminds residents to reduce their speed and drive with extra care in construction zones.

The following areas are scheduled for infrastructure work expected to affect the public in August. Please note that scheduled dates are subject to change.
