It was erected in 1897 as a wagon bridge.","why_significant":"The bridge is significant for transportation and engineering as an intact, representative example of a pin-connected Baltimore (Petit) through truss built with patented Phoenix columns. It reflects the Phoenix Bridge Company's design and the late nineteenth century shift to manufactured metal bridges on rural New York roads. At 206 feet it is a relatively large span and one of only a small number of its type remaining in the state.","narrative":"Carrying Wood Road over the Cohocton River in the town of Campbell, this 206-foot metal through truss bridge was erected in 1897 as a wagon crossing. It is a single span resting on mortared stone abutments capped with concrete, and its eight-panel Baltimore truss combines elements of the Pratt and Warren forms. The top chord and portal end posts use Phoenix columns, a patented built-up tubular member, and the lower chord is made of paired wrought iron eye bars joined with pins. The bridge was rehabilitated in 2003, including new floor beams, stringers, decking and a steel box railing, and it still serves pedestrians and vehicles. It was listed for its transportation and engineering importance. Few early metal truss bridges survive in New York, and this large, highly intact example represents the Phoenix Bridge Company's Baltimore truss design and the shift from timber to manufactured metal spans in rural road building.","period_of_significance":"1897","architect_builder":null,"architectural_style":"No style (metal pin-connected Baltimore through truss)","criteria":["A","C"],"status_note":"Rehabilitated in 2003 by the town of Campbell; remains in use as a pedestrian and motor vehicle crossing on a rural town road.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:52.914095-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/05000169.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75322017","wikipedia":"https://en.wikipedia.org/wiki/Wood_Road_Metal_Truss_Bridge","wikidata":"https://www.wikidata.org/wiki/Q8032269"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/steuben-county/wood-road-metal-truss-bridge-05000169/"}
