Read an article about the Schaub variant truss.
Another standardized but unique former Frisco truss crosses the Neosho River just to the east of Oswego.
Built in 1905 by King Bridge Company, the bridge features a large 6-panel pin connected Schaub variant Through Truss. This span was originally built with a deck girder span on the east and trestle approaches on the west.
However, the original west approaches were replaced in 1962 with I-Beam spans. Currently, the entire bridge sits on concrete substructures.
The Schaub variant truss is a take on the traditional Warren design, developed by Julius Schaub in 1901. While the original design featured a combination of pin and riveted connections, this bridge utilizes mostly pinned connections, with no crash bars on the end panels.
The Schaub design offered a savings of material and a reduction of traditional stresses in truss members. Schaub considered it to be an ideal link between long pin connected spans and short riveted spans.
The rail line this bridge carries is lightly used. It is hoped this unique bridge can be preserved for years to come.
The author has ranked this bridge as being moderately significant, due to the truss design.
The photo above is an overview. The bridge can be accessed from US-166, which the bridge sits parallel to.
