Multiple road closures and traffic disruptions are scheduled across Greater Montreal for the weekend of September 12 and 13, 2026. The closures are linked to two major events: the Grand Prix cycliste, a competitive bike race, and a concert by the rock group AC/DC. Both activities are set to take place on Saturday, September 12, and continue into Sunday, September 13, prompting authorities to block sections of the road network to accommodate participants and spectators.
The Grand Prix cycliste will use designated streets as part of its race course, requiring temporary removal of vehicular access. Simultaneously, the AC/DC concert, a high‑profile music performance, will be held at a venue that also necessitates the sealing off of nearby thoroughfares for crowd control and safety measures. The overlapping schedules mean that several key routes will remain inaccessible for the duration of the two‑day period.
Motorists traveling through Greater Montreal are expected to encounter altered traffic patterns, longer travel times, and detours around the closed sections. Public transit routes that share the affected streets may also be rerouted, and parking options near the event sites could be limited. Drivers are advised to plan alternative pathways and allow extra time for their journeys.
These disruptions add to the regular traffic impacts that Montreal experiences from construction projects and large public gatherings. The city’s transportation network often adjusts to accommodate such events, balancing the needs of residents, commuters, and event attendees. While the closures are temporary, they underscore the recurring need for coordinated traffic management during major weekend activities in the region.
Residents and visitors are encouraged to stay informed through official traffic updates and to follow posted signage while navigating the city during the event weekend.
