The Townline Road / Rail Tunnel, running east-west beneath the new channel on the old Townline Road (Welland) was opened to automobile traffic in July 1972 and to railway traffic in February 1973.
The 1000-foot long Welland Dock was built on the west side of the new channel for the use of the city of Welland and its industries. It was specially designed to allow for the easy access of railways.
The historic aqueduct in Welland has not been in use since the construction of a section of canal which allows vessels to by-pass this section of the waterway.
The aqueduct in Welland was once an integral part of the canal system. Due to the construction of a by-pass which allowed vessels to skip a huge portion of the waterway the aqueduct was taken out of operation.
