A significant multi-vehicle collision occurred on Highway 640 on Friday, March 20, 2026, involving five passenger cars and a semi-truck, resulting in one woman being hospitalized with serious injuries. The incident took place in the westbound lane near Exit 28 shortly after 12 p.m., according to authorities.
Details of the Collision and Response
Sergeant Valérie Beauchamp of the Sûreté du Québec (SQ) confirmed that a 24-year-old woman was transported to a hospital for treatment of serious injuries sustained in the crash. Beauchamp emphasized that while her injuries are serious, her life is not in danger. The collision prompted immediate road closures, with Highway 640 completely shut down in the westbound direction and the left lane closed eastbound to facilitate emergency response and investigation.
According to Québec 511, the highway was closed in both directions between Exit 28 and the following exit, with traffic being redirected to a service road. In a post on social media platform X, they warned drivers to "expect congestion" due to the closures, which were expected to last for an undetermined duration.
Investigation and Contributing Factors
Police have indicated that weather conditions and a traffic slowdown "may have been a factor" in the six-vehicle pileup. Sergeant Beauchamp stated that an accident investigation will be conducted by the SQ on-site to determine the exact causes and sequence of events leading to the collision. This investigation aims to provide clarity on how the incident unfolded and whether any additional factors contributed to the severity of the crash.
The closure and subsequent traffic diversions caused significant disruptions for commuters and travelers in the area. Authorities urged motorists to avoid the vicinity and seek alternative routes while cleanup and investigative work continued throughout the day.
Impact and Ongoing Developments
This incident highlights the dangers associated with highway travel under adverse conditions and during periods of heavy traffic. The involvement of multiple vehicles, including a large semi-truck, underscores the potential for serious outcomes in such collisions. As the investigation progresses, further details may emerge regarding the specific roles of weather and traffic patterns in this event.
Local residents and drivers are advised to stay updated through official channels like Québec 511 for real-time traffic alerts and road condition reports. The SQ continues to work on scene to ensure public safety and gather evidence for a comprehensive analysis of the crash.
