Carlton St Bridge
As of October 22, 2026, the Carlton St bridge in St. Catharines usually stays closed about 17 minutes each time it opens for a ship (typically 15–20 minutes), based on 286 recorded closures and closing-soon alerts.
Carlton Street, Regional Road 83, crosses the Welland Canal in St. Catharines as Bridge 3A. The odd number is a bit of canal history: it replaced the original Bridge 3 after an accident. It's a bascule, so the deck swings up on a counterweight when a ship needs through.
