This old and historic truss bridge crosses the Big Sioux River just west of Brandon.
The bridge features a quadrangular through truss main span, which has a more "boxy" design than other similar structures.
This truss has riveted connections, and a pedimented portal bracing.
In addition, the bridge is approached by several spans of wooden trestle on either side.
The piers for the truss span are however made of stone, encased in concrete.
The author has ranked this structure as moderate significance for a number of reasons. The first is the age of the structure. The bridge is an early example of a Lassig Quadrangular Through Truss. In addition, it is a moderately early example of the design to start with.
