This unique little gem sits alongside IL-3 in East Alton. Long abandoned, it currently carries a pipeline.
This bridge was built in 1902 to replace a Big Four bridge that was destroyed by flooding. It contains a simple design, with a Pratt Through Truss approached by a Through Girder span.
The main span is a typical Pratt Through truss. It contains 6 panels, with pinned connections. It is a very lightweight bridge for the type of traffic it was seeing.
The substructures were built of stone and concrete. The pier is built of concrete, while the west abutment is built of stone.
The bridge is in remarkably good condition for the time it has been abandoned. It is likely being maintained by a private organization, likely the owner of the pipeline.
This bridge has been rated by the author as being moderately significant, because it is a good late example of a pin connected Pratt Through Truss. In addition, it contains a high amount of historic integrity.
The photo above is an overview. The author is researching further to confirm the build date.
