There is a distinct possibility that the shorter of the two truss spans in this bridge is actually the former main span from the Rock Island's original crossing site of the Chariton River, located a few miles to the north. A rough estimate of the old main span's length using the Google Earth ruler tool is approximately 120ft, nearly identical to the estimated length of the short truss on this bridge. This would help to explain the unusual design of the new bridge, with mismatched DPG and Warren through truss spans of varying lengths and designs. The design of the truss span in question is also similar to other simple warren through trusses the Rock Island erected in great numbers in the late 1800s/early 1900s.
