Four Welland Canal bridges close Mar. 17–21 for maintenance before St. Lawrence Seaway opens Mar. 22.

Four bridges over the Welland Canal in St. Catharines and Port Colborne will close temporarily from March 17 to 21 for preventive maintenance ahead of the St. Lawrence Seaway’s seasonal opening on March 22. Vehicle and pedestrian traffic will be prohibited during specified hours each day, with closures varying by day. The work aims to ensure safe and efficient operations, and officials urge travelers to plan alternate routes as schedules may change.
