The City of Thunder Bay is sharing details of construction projects expected to impact vehicular, cycling, and pedestrian travel in the month of June.
 
The City is investing $55 million in 2025 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 delays for travellers. The City hopes to minimize disruption by sharing project details with the public.

All residents are reminded to reduce their speed, be alert, watch for workers and drive with extra care in construction zones.
