Significant congestion is forecast for both entering and leaving the island of Montreal this weekend as construction work proceeds on the western outskirts and the Louis‑Hippolyte‑La Fontaine bridge‑tunnel. The roadworks are scheduled for Saturday and Sunday, October 23‑24, 2026, and are expected to slow traffic at key exit points.
Drivers are advised that the planned projects in the western part of the island and on the major bridge‑tunnel have historically led to heavier traffic flow, increasing the likelihood of delays during the two‑day period.
