Description 

This bridge is one of two bridges that comprise the Seaway International Bridge/Three Nations Crossing. The south channel bridge is a traditional wire cable suspension bridge. However, the stiffening truss of the bridge is unusual in that it is a "railing height" truss - part deck truss and part pony truss. Instances of this rare arrangement outside of Chicago, Illinois where it was developed are exceedingly uncommon.

Seaway International Bridge (South)

It's unfortunate and rather quite strange that there do not appear to be any photos of the southern suspension bridge available on the Internet other than Nathan Holth's photos at HistoricBridges.org, which are clearly labeled as "Do not reuse". Someone should try to find and/or obtain a photo of the southern span. Perhaps I'll try to get up there this summer, but with coronavirus, who knows what will happen.
