The Library of Congress page on the Sault Ste. Marie International Railroad Bridge that spans the Soo Locks from Michigan to Canada at St. Marys Falls explains that:

The Sault Ste. Marie International Railroad Bridge has nine camelback truss spans crossing the St. Marys River with bascule and vertical lift bridge components crossing the American Locks at the St. Marys Falls Canal. It is the only bridge in the United States known to include these three types of spans in a single structure to use an interlocking mechanism to connect the leaves of the double-leaf bascule span.

It is Michigan’s most significant railroad bridge from an engineering history standpoint and is eligible for listing in the National Register of Historic Places.

    Is this bridge still in use to rail traffic. I saw it recently and it looked abandoned, but still magnificent.
