It was built in 1892 by the King Bridge Company of Cleveland, Ohio.","why_significant":"The nomination presents the bridge as a typical example of the Pratt through truss type and as the product of a leading nineteenth-century American manufacturer of metal truss bridges. It is one of fourteen representative examples of this type included in the group nomination. The bridge is described as unusual because few truss bridges of this kind are found in central Pennsylvania, where most such bridges are located in the northwest.","narrative":"Built in 1892 by the King Bridge Company of Cleveland, Ohio, this steel Pratt through truss carries vehicular traffic across the West Branch of the Susquehanna River in Greenwood Township, Clearfield County. The single span measures 189.8 feet overall and rests on coursed ashlar stone abutments. Its eleven-panel Pratt web and riveted connections are typical of the type, which was widely produced by American metal bridge firms in the late nineteenth century. A bronze plaque on the bridge names the county commissioners and the builder, and round ornamental figures appear beneath the top chord. The bridge is one of fourteen representative examples of the Pratt through truss in the group nomination. Its listing rests on its engineering value: it is one of only a few truss bridges of this kind in central Pennsylvania, where such structures are rare compared with the northwest of the state.","period_of_significance":"1892","architect_builder":"King Bridge Company (bridge company)","architectural_style":null,"criteria":["C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:37.321856-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/88000846.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/88000846/2cf7b6d4bd-800.webp","url_1600":"https://nationalhistoricalregister.com/media/88000846/2cf7b6d4bd-1600.webp","licence":"Public domain","author":"PennDOT","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Bridge_in_Greenwood_Township.jpg\" rel=\"noopener\">PennDOT</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Bridge_in_Greenwood_Township.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992780","wikipedia":"https://en.wikipedia.org/wiki/Bridge_in_Greenwood_Township","wikidata":"https://www.wikidata.org/wiki/Q4966358"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/clearfield-county/bridge-in-greenwood-township-88000846/"}
