Another day, another water main break in Montreal. The latest in on St. Michel Blvd. in Rosemont.

Subterranean pipes burst and sent water flowing to the surface at 2:15 a.m. Wednesday, splitting the pavement along the width of the street.

City crews arrived at the site of the leak at 6:30 a.m. and around 11 a.m. had excavated deep enough to locate the broken pipe.

Serge Fortin of the Rosemont-Petite-Patrie borough said the pipe that broke was a 20-cm water main, and likely succumbed to freezing temperatures.

St. Michel Blvd. was closed overnight, and is expected to remain closed between Laurier St. and Masson St. until 4 p.m.

Police are on hand to co-ordinate traffic and direct drivers and buses toward the detours.
