The Samuel‑De Champlain Bridge will be inaccessible to vehicles from Friday, June 19, through Sunday, June 21, 2026. Drivers who normally rely on the span will need to find alternative routes for the three‑day period.
The bridge, which carries a substantial flow of commuters and commercial traffic across the St. Lawrence River, links the island of Montreal with the South Shore. Its closure removes one of the primary connections between the two sides of the river, temporarily shifting the burden to other crossings in the region. Motorists are expected to encounter longer travel times as they navigate detours, and local authorities have advised that the disruption could affect rush‑hour patterns on nearby highways and arterial roads.
While the shutdown is limited to the weekend, the impact on drivers may be felt beyond the dates of the closure as traffic adjusts to the temporary loss of the route. Residents and commuters are encouraged to plan ahead, consider public transit options where feasible, and stay informed of any updates regarding the reopening schedule. The closure underscores the bridge’s role as a vital piece of infrastructure in the Montreal metropolitan area.
