Montreal residents and visitors should expect a series of traffic and construction disruptions on Saturday, September 12, and Sunday, September 13, as the city hosts a major cycling Grand Prix and an AC/DC concert across the Greater Montreal area. Both events will require road closures and extensive crowd‑management measures, affecting normal travel patterns throughout the weekend.
The cycling Grand Prix will see a fleet of racers navigating a course that weaves through several neighbourhoods in Greater Montreal. To accommodate the race, authorities will close selected streets and redirect traffic onto alternate routes. Construction crews are also slated to adjust ongoing work zones to ensure the race can proceed safely, meaning drivers may encounter detours and temporary signage throughout the day.
In parallel, the legendary rock band AC/DC will perform a highly anticipated concert at a large venue in the city. The event is expected to draw thousands of fans, prompting the deployment of additional security personnel and the establishment of crowd‑control zones. Access roads to the venue will be partially blocked, and public transportation services may be rerouted to handle the influx of concertgoers.
Montreal has a history of adjusting its transportation network when large sporting events and major concerts coincide over a weekend. City officials have previously coordinated with police, transit agencies, and event organizers to minimize inconvenience while maintaining safety. Motorists are advised to plan alternate routes, allow extra travel time, and stay informed through local traffic updates. Pedestrians and cyclists should also be aware of temporary lane changes and follow posted directions to avoid delays.
The combined effect of the Grand Prix and the AC/DC concert underscores the city’s capacity to host high‑profile events, even as it temporarily reshapes the flow of traffic and construction activity for the two‑day weekend.
