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.
A ship passes through the swing bridge on Main Street in Welland. Officially known as the Alexandra Bridge and opened in 1902, it was replaced by the Main Street Lift Bridge in 1930.
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.
