On Saturday, October 23, 2026, and Sunday, October 24, 2026, two major routes on Montreal island will be closed for repair and construction work. The closures will affect Highway 40 at Senneville near the Île‑aux‑Tourtes bridge and the Louis‑Hippolyte La Fontaine tunnel.
Both corridors are important for commuters entering and leaving the island, so the work is expected to impact traffic flow during the weekend.
