For those who might wonder, this appears to be a vertical lift bridge whose towers were cut off now that the river is not navigable for tall boats.

The railroad bridge looks like an overhead counterweight trunnion bascule bridge designed by Strauss Bascule Bridge Company. It may date to ca. 1915, since it is very similar to the Deering Bridge in Chicago: http://www.historicbridges.org/bridges/browser/?bridgebrowse...

I wonder how old that RR bridge is.
