Infrastructure maintenance and inspections are causing various road closures and traffic disruptions across the Montreal and Laval regions in Quebec.

In Repentigny, the Ministère des Transports et de la Mobilité durable scheduled night-time lane closures on Highway 40 between Valmont Street and Industrial Boulevard from August 20 to September 2.
