Significant traffic delays are anticipated for vehicles entering and leaving Montreal on Saturday and Sunday, October 24‑25, 2026. The congestion is linked to ongoing construction work on the island’s western side and on the Louis‑Hippolyte‑La Fontaine bridge‑tunnel.
Drivers are advised that the planned road and bridge‑tunnel projects typically cause higher traffic volumes during peak travel periods, contributing to the expected slowdown.
The forecasted bottlenecks affect both inbound and outbound routes across the city’s main entry points for the weekend.
