In 1888, the Cherokee & Dakota built a 59 mile route between Cherokee and Onawa. This route connected to other routes being constructed in the area.
The same year, the C&D became a part of the Dubuque & Sioux City Railroad, who already operated a mainline between the namesake cities.
The Illinois Central leased the D&SC, and it fully merged in 1946.
As a branch line, this route gradually became excess for the Illinois Central, which had reorganized as Illinois Central Gulf in 1972.
The entire line was abandoned between 1978 and 1980. Today, most structures on the line remain but the tracks are long gone.

Located south of Cherokee, this large through truss bridge crosses the Little Sioux River.
Built in 1886 during the initial construction of this route, the bridge features a single pin connected 7-panel Pratt Through Truss structure, set onto stone piers. The bridge also is approached by trestle spans on both sides. The truss also features a unique double jointing on the lower connections at the outermost vertical members.
This type of bridge is a standardized design on the Illinois Central routes. Seen throughout Illinois, Iowa and Wisconsin, these bridges were simple and durable. Many continue to exist today.
It is unknown who currently owns this bridge, although the author accessed it with permission from the nearby wastewater treatment plant, and the property should be respected.
Overall, the truss appears to be in good condition, although most of the deck is in poor condition. The approaches are in poor condition, with significant deterioration. It is hoped that this bridge will continue to be preserved.

The author has ranked this bridge as being moderately significant, due to the truss design. It is a good example of a truss left standing after the removal of the railroad.
