Road Closures Due to May 2022 Flooding Situation 

The City of Thunder Bay is currently working to address and monitor city-wide flooding risks, following the Flood Watch Warning issued by the Lakehead Region Conservation Authority. The flooding situation has resulted in road closures across the city, and many other roads that are experiencing significant flooding, but remain open.   

See the City Street Status Map (updated May 25, 2022 at 3:16 pm) which indicates which roads are closed, and which roads are open but may close soon.  

The flooding situation is changing very quickly and the City will continue to monitor and respond accordingly. There may be roads in and around the city not included in the map, that may be experiencing ponding and flooding. The City is reminding residents to exercise caution in and around area waterways. Drivers are asked to proceed with caution on roads with higher water levels, as the adjacent ditch may not be visible and is a hazard.

The City's Roads and Engineering Divisions maintain our roads and sidewalks. Check out the latest road work updates and whether heavy load restrictions are in effect. Find out where to park and learn about our traffic signal pedestrian and crossing system, roundabouts and crossing guards. The City also outlines our snow removal system during the winter months and provides an opportunity for residents to report potholes.

Street Sweeping

Street sweeping removes sand so it does not hinder visibility of road line markings, keeps the lanes clear for the safety of pedestrians and cyclists, reduces the risk of damage to vehicles, and keeps road sand out of our rivers and lakes. Motorists and pedestrians are asked to use extra caution when travelling near a street sweeper.

Each year, north side and south side neighbourhood zones are randomly prioritized from 1 to 10, and swept in that order. Check this year's map to see where your neighbourhood falls in the sequence this year.
