The bridge is historically significant as an example of a small-scale 19th century stone arch highway bridge. The stone used in the bridge is locally quarried gray limestone. Ornamentation on the bridge includes protruding keystones at the top of the arch, a slight peak at the top of the arch, and a string course that matches the roadway level. The bridge resembles other stone arch bridges built in Minnesota townships during the late 19th century and early 20th century, but the ornamentation sets it apart. Another facet of historical importance is the fact that the bridge has never been substantially altered during its lifetime, except for a concrete cap replacing the original coping at the top of the railings. The bridge has been listed in the National Register of Historic Places (#89001825) due to its historical integrity.
