It is also known as Black Covered Bridge.","why_significant":"The bridge is a modified version of the Long truss, with 10 panels per span, and the form calls it the only one of its kind. It is also a beloved local landmark that residents fought to keep when a new section of SR 732 bypassed it in 1951.","narrative":"Spanning Four Mile, also called Talawanda, Creek one mile north of Oxford in Butler County, Ohio, this two-span wooden covered bridge dates to about 1869. It has a sheet metal roof, tall vertical siding, stone abutments and a stone pier, plus added steel piers. Each span has a 103-foot clear span, and the total length is 224 feet. Its truss is a variation of the Long truss patented in 1830. The outer five panels of each span are true Long trusses, while the center five resemble a Childs truss, which makes the design a one-of-a-kind modified version. The builder and exact construction date are unknown. The names come from a nearby family named Black and from Pugh's Mill, located a short distance north. In 1951, when a new section of SR 732 was planned to bypass it, local citizens fought to keep the bridge. It is now closed to traffic, and a turn-around serves visitors.","period_of_significance":"about 1869 (19th Century)","architect_builder":null,"architectural_style":"Modified Long truss covered bridge (variation of the Long truss patented 1830)","criteria":[],"status_note":"Condition marked good; closed to all traffic, auto and pedestrian, with a turn-around provided for visitors.
