This large swing bridge crosses Buffalo Lake in a rather remote part of Marquette County.
Buffalo Lake is actually a pool of the Fox River, which flows northwards towards Green Bay.
The bridge here is a massive swing bridge. The main span features large Quadrangular Through Truss swing span. This span has riveted connections and massive M-Frame portal bracings.
Approaching the main span structure are deck girder spans, supported on steel bents. The remaining substructures are of concrete construction.
The main truss span has been constructed for two tracks, while the approaches only have been constructed for one. The towers however, are all expandable for two tracks.
It appears that the swing mechanism is still fully in place, and the bridge could be moved with a little work.
The best way to access this bridge is from Lakeview Drive. Since I-39 is on the other side of the bridge, this is not an ideal area to access the bridge from.
The author has ranked this bridge as being regionally significant, due to the uncommon design and the unique use of a swing span.
