The form gives an 1832 construction year, though the OCR text also contains a conflicting 1872 build date on a field label, so the date is uncertain.","narrative":"A covered bridge spanning Tinicum Creek in Tinicum Township, Bucks County, Pennsylvania, owned by Bucks County. The structure uses a Town truss, measures about 110 feet along its end post length and 15 feet in width, and is recorded in good condition. It is one of the covered bridges in Bucks County documented as part of a multiple property group covering the Delaware River watershed. Covered bridges of this type were a common response to the need for durable crossings over streams in the region, and the bridge's wooden construction reflects that building tradition. Its listing rests on its value as an example of this kind of timber bridge technology. The surviving record places its construction in 1832, though a second date appears in the scanned material, so readers should consult the full nomination for the build year.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition is recorded as good.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.657685-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003444.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003444/1a2324f2f1-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003444/1a2324f2f1-1600.webp","licence":"CC BY-SA 3.0","author":"Djmaschek","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Frankenfield_Covered_Bridge_1.jpg\" rel=\"noopener\">Djmaschek</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Frankenfield_Covered_Bridge_1.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992476","wikipedia":"https://en.wikipedia.org/wiki/Frankenfield_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5490645"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/frankenfield-covered-bridge-80003444/"}
