Humpback Bridge
- Also known As: Humpback Bridge Wayside
Humpback Bridge is an exceptionally fine example of nineteenth-century covered bridge construction, and an outstanding example of a timber multiple kingpost truss, of which approximately 90 historic (pre-1955) examples survive in the United States. It is nationally significant under NHL Criterion 4, as a property that embodies the distinguishing characteristics of an architectural type specimen exceptionally valuable for a study of a period, style, or method of construction, and under NHL Theme VI, Expanding Science and Technology, Technological Applications. The bridge is the older of two surviving covered bridges with radically-cambered chords in the United States, the other being the Geer's Mill Bridge (1874) in Vinton County, Ohio. Humpback Bridge has been well maintained and it retains an uncommonly high degree of historic and structural integrity. It was inventoried by the Historic American Buildings Survey (HABS) in 1958, and recorded by the Historic American Engineering Record (HAER) in 1970 and 2002. It was listed in the National Register of Historic Places in 1969. Of the approximately 690 historic (pre-1955) covered bridges surviving in the United States, Humpback Bridge is an outstanding example of covered bridge construction and preservation. - NRHP, 26 July 2011
