A major water main break has shut down a secondary street during the morning commute.

Cavalier Drive between Fairlane South and the Safeway Entrance just off Portage Avenue has been shut down due to a major water main break. The break may include a possible hole in the road.

Motorists are being told to use alternate routes, which could lead to significant delays on Ness Avenue and Sturgeon Road.

There is no current timeline on how long the road will remain closed.
