This interesting looking structure crosses the Fox River near Princeton. It is a no longer operational Pony Truss Swing Span, which is rare compared to other designs.
Currently, the bridge shares a design with the Kaukauna Swing Bridge and the Allouez Swing Bridge.
The main truss is a 13 panel, Parker Pony Truss balanced on a swing pier. It features riveted connections.
On the south end, the truss is approached by a single I-Beam span, which was added in 1908.
The bridge is unique, as it makes one wonder about the status of this river when it was constructed. The Fox River at this spot is only a couple feet deep, and not nearly wide enough to fit a full sized vessel through.
In addition, the levers which made the span turn have been long removed. However, the original gears still exist.
The photo above is an overview looking north. The author has ranked this bridge as being regionally significant, due to the rare small scale example of a swing span.
