Attractions & Events
Thorold Tunnel
The Thorold vehicle tunnel was built under the existing Welland Canal approximately 28 years ago. Maintained by the St. Lawrence Seaway, it allowed quick access across the canal other than waiting for long periods of time at lift bridges. This tunnel is unique in its construction because it was built under an already existing canal.
