ISRY - Chariton River Bridge
Posted December 23, 2017, by Dylan VanAntwerp (dylan_vanantwerp [at] live [dot] com)

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.

This railroad bridge was originally built and owned by the Chicago, Rock Island, & Pacific railroad and was part of the Golden State Route mainline. This bridge was built as part of a 1946 realignment through much of SE Iowa which reduced grades and mileage. The original bridge was several miles north, and I believe you can still see the stumps of the timbers sticking out of the river bottom. The original crossing location was just south of the present day Highway 2 bridge. The Rock Island went bankrupt and ceased operations in 1980.
