Its exterior has half-vertical plank siding, a gable roof and portals, the same general styling as most of the other remaining covered bridges in Somerset County. Its interior walls are lined with horizontal planks, a feature the record notes as particular to this bridge. The bridge was listed as part of a multiple-property group of Somerset County covered bridges.
