This small truss bridge crosses Split Rock Creek in the Sioux Falls suburb of Corson, which lies just north of Brandon.
This bridge features an 8 panel, riveted warren pony truss main span. In addition, it is approached by deck girder on either side.
The bridge appears to be in fair condition. The bridge sits on stone substructures. It is worth noting that the stone piers appear to be constructed of a more uneven granite, instead of the typical limestone, such as the abutments and one pier.

The bridge has been ranked as moderately significant by the author, due to the uncommon design for the area and the unique features, such as the piers.
The photo above is an overview. The bridge can easily be seen from nearby roads.
