Dennis DeBruler Both the bridge and boat are historic. Too bad the bridge might soon be torn down: http://historicbridges.org/bridges/browser/...

Dennis DeBruler Bridge Hunter has the comment: "A report produced for the owner recommends South Channel bridge replacement in 2016-2018 and historic bridge demolition in 2019." Since I see no sign of construction in your photos, it seems the plans have been delayed. https://bridgehunter.com/ny/jefferson/5523240/
The St. Lawrence Seaway channel goes below the American Bridge. The bridge was built in 1938. It was rehabilitated in 1986 and 2000, but the current plans are to replace it. The future of the Canadian Bridge remains uncertain.

Please read Historic Bridges for why this bridge has cable stays and metal bars in addition to the normal suspension cables.

The Canadian Bridge has arch and truss spans as well as a suspension span. I didn't notice the arch span in Avocado's photo until I came across Marge's photo.

The American Bridge has long approaches to achieve the needed Seaway clearance.
