Part of westbound Notre-Dame Street in Montreal’s Mercier–Hochelaga-Maisonneuve borough is set to be closed for an indefinite period of time starting Tuesday morning. This comes after a 10-inch water main break that occurred near Alphonse-D.-Roy Street, according to city spokesperson Philippe Sabourin. “The valves were closed yesterday [Monday], and repairs were scheduled for today [Tuesday] with one lane closed,” he explained. “Since the closure is not watertight, [the borough] had no choice but to completely close the westbound lanes.” The closure is set to take place between Davidson and Alphonse-D.-Roy streets, with a detour via Sainte-Catherine Street. Montrealers are being asked to avoid the area.
