Châteauguay's Mercier Bridge approach generates the highest collision frequency per kilometre of any South Shore bridge corridor — the bridge is routinely closed during Kahnawake community events, creating bottleneck congestion on Boulevard d'Anjou and all South Shore approaches. This bottleneck produces rear-end collision frequency above all comparable Quebec suburban markets in the April 2026 private carrier data.

Châteauguay commuters: when the Mercier Bridge closes, Autoroute 30 and Highway 132 carry overflow traffic — planning alternative routes in advance and avoiding the immediate bridge approaches during closure periods is the most practical risk mitigation for Châteauguay drivers.
