Mellanby Ave Bridge
As of June 9, 2026, the Mellanby Ave bridge in Port Colborne usually stays closed about 15 minutes each time it opens for a ship (typically 13–17 minutes), based on 290 recorded closures and closing-soon alerts.
Mellanby Avenue crosses the Welland Canal in Port Colborne as Bridge 19A, a short way from the Main Street crossing. It's a bascule, and it's the one drivers fall back on when Main Street is up or out of service. Both sit near Lock 8 at the canal's south end.
