A collision involving a heavy truck on September 3, 2026, shut a key segment of road on Montreal’s North Shore. The incident immediately halted traffic flow, creating extensive delays that left thousands of motorists unable to reach their destinations as the evening commute progressed. The blockage persisted, preventing the normal flow of traffic.
The affected stretch lies on the North Shore corridor, a primary commuter artery that links the island of Montreal with its northern suburbs. Because the corridor carries a high volume of daily traffic, any obstruction can quickly affect a large number of drivers. In this case, the blockage impacted thousands of vehicles, turning the route into a long line of stationary cars and forcing many commuters to search for alternative ways home. The corridor’s importance for commuter traffic makes any incident a significant disruption for the region.
With the main thoroughfare blocked, traffic backed up onto adjoining streets, extending congestion beyond the immediate crash site. Drivers reported being stuck for prolonged periods, and the surge of vehicles seeking secondary routes added pressure to nearby roadways. The situation compounded the usual evening rush, making the return journey unusually slow for those traveling toward residential areas on the North Shore.
Emergency crews worked to remove the wreckage and restore normal flow, but the size of the heavy truck and the extent of the collision meant the road stayed closed for several hours. As a result, the delay persisted well into the night, affecting the travel plans of the thousands of motorists caught in the jam.
