Both the Samuel‑De Champlain bridge and the Victoria bridge will be closed to vehicular traffic on Saturday and Sunday, August 29‑30, 2026. The closures, ordered for road work projects, affect the two main crossings that link Montreal with the South Shore, interrupting the usual routes used by commuters.
The Samuel‑De Champlain bridge, a key artery for traffic entering the city from the south, will be inaccessible for the entire weekend. Likewise, the Victoria bridge, another primary link between Montreal and surrounding municipalities, will also be shut down for vehicular travel. The simultaneous shutdown of these two structures means that drivers who normally rely on them will need to seek alternate pathways.
Motorists are advised to plan for longer travel times and to consider using other bridges or routes that cross the Saint Lawrence River. While the exact detours have not been detailed, drivers can expect increased congestion on the remaining crossings and on surface streets that serve as secondary options. Public transit services may see higher ridership as commuters look for alternatives to driving.
The road work projects prompting the closures are part of ongoing maintenance and improvement efforts aimed at preserving the safety and functionality of the bridges. Officials have indicated that the work will be completed over the weekend, allowing the bridges to reopen for traffic after Sunday. Residents and commuters are encouraged to stay informed about traffic updates and to adjust their travel plans accordingly to minimize disruption during the brief shutdown period.
