View An Application For Funding To Replace This Bridge

This bridge is, like most historic railroad swing bridges over the Mississippi River, at risk for demolition and replacement. This is most unfortunate because this is a highly significant bridge. Its swing span of 460 feet is a long span example of its type. The truss configuration is quite unusual on the swing span as well. Many swing bridges have a truss arrangement quite different from fixed bridge due to the changing forces a swing span encounters when carrying load and when swinging open. However, this bridge is particularly unusual. The ends of the swing span have a Warren style truss configuration, but near the center "tower" portion this design loses its pattern and has a design that is difficult to categorize, but is somewhat like a Baltimore truss. Moreover, the tower portion of the bridge has a very narrow appearance compared to other swing bridges with a similar shape. In short, the swing bridge is fairly unusual in its design. The approach spans are noteworthy also. There is a traditionally composed Parker truss immediately east of the swing span. East of that, there is a lattice truss. Lattice trusses are in general rare, but were preferred by the original owner of this bridge, the Chicago and NorthWestern Railroad. East of this bridge, there is a second fixed longer bridge composed of many lattice truss spans.

Special thanks to John Marvig for graciously sharing his photos of this bridge. This is a very time consuming bridge to document fully due to its multiple sections.
