| Saginaw Swing Railroad Bridge | Railroad (CSX, Central Michigan Railroad) Over Saginaw River | Saginaw: Saginaw County, Michigan | Metal Pinned Baltimore Through Truss, Movable: Swing | 1914 By: Wisconsin Bridge and Iron Company of Milwaukee, Wisconsin |
This beautiful swing bridge was built by the Wisconsin Bridge and Iron Company in 1914. Plaques, which are all cracked from pack rust beneath them, convey this information. There are two big plaques, both mounted on the western end posts on the eastern half of the swing span and also a small plaque also saying the same thing mounted on the western endpost of the west half of the swing span. Extensive lattice on this hulk of a bridge adds intricacy to the structure. Deck plate girders provide an approach to the structure. There is also a through truss approach span at the western end of the bridge. The truss configuration on all spans is of the Baltimore variety. Connections on the bridge are riveted. The bridge no longer operates, but enough gears and gizmos remain to allow a picture of how the bridge worked to be formulated.
