The City of Thunder Bay is investing $18 million in 2020 on road and sidewalk rehabilitation, residential paving, sanitary and storm sewers, watermain repair/replacement, bridge and culvert work, and streetlight renewal.

Road work can result in road closures, detours and delays for drivers. All residents are reminded to reduce their speed, be alert, watch for workers and drive with extra care in construction zones.

The following areas are scheduled for, or are currently undergoing, road and other major infrastructure work that is expected to affect traffic in the coming month:

The above list includes major, traffic-affecting construction. Other work, including sidewalk replacements and curb and gutter repairs, is scheduled for residential areas and other areas around the City. Schedules are subject to change.


The fall season often brings community events, resulting in temporary street closures. Residents are reminded to obey detours and drive with extra care in the vicinity of these closures.  

Temporary street closures for events will be in effect:

  • Whiskey Jack Crescent, from Chippewa Park to Sandy Beach Road on Sunday, Sept. 27 from 9 am to 1 pm for The Chippewa Challenge
