The City of Thunder Bay is sharing details of construction projects expected to impact drivers, cyclists and pedestrians in the month of July.

The City is investing $42 million in 2024 to fund crucial infrastructure work including road rehabilitation, sidewalk replacement, sewer and watermain repairs and replacements, and bridge and culvert renewal.

While this work is essential to maintain our community’s infrastructure, it can result in road closures, detours, and delays for travelers. The City hopes to minimize disruption by sharing project details with the public.
