This iconic structure crosses the St. Croix River at Hudson, just upstream from the I-94 bridge.
The bridge is a rather noticeable structure, employing an odd mixture of spans. The main span is a swing span, containing a pair of 6 panel, riveted Pratt Through Trusses.
In addition, another 6 Panel Pratt Through Truss with riveted connections and a 6 panel Parker Pony Truss with riveted connections make up the east end of the bridge. When constructed, there were nine more pony trusses along the east side of the bridge, which were filled in prior to 1938. The pony truss was originally built in 1898, while the remaining bridge was built in 1912-13.
The bridge rests on a combination of stone and concrete substructures.
The current bridge replaced two predecessors. The first structure at this location was a wooden swing span, with a long trestle approach on the east side. This approach was nearly 1,000 Feet Long.
In 1881, this span was replaced with a Lattice Truss style swing span, along with a Lattice through truss and numerous pony truss spans.
This bridge was replaced in 1912 by the current bridge. Much of the long approach has been converted to a long fill in the river.
Presently, best views of this bridge would come by boat. However, walking along the banks of the river or photographing it from the Hudson River Walk works as well.
The author has ranked this bridge as being moderately significant, due to the truss design.
The photo above is from Quant Avenue, on the Minnesota Side of the river.
