Its high arch rises to the eaves, and the vertical plank siding covers only three-quarters of the sidewalls, so the structure remains visible from outside. The span measures 63 feet 6 inches in length and 14 feet 5 inches in width, with a clearance of 10 feet 8 inches and a posted load limit of 3 tons. It carries a township road that serves several small farms in the broad valley. The bridge is part of a group of covered bridges in Lycoming and Sullivan counties that was nominated together as a thematic group, and it is one of the surviving examples of the Burr arch type in the region. It is regarded as being in very good condition.","period_of_significance":null,"architect_builder":null,"architectural_style":"Burr arch truss","criteria":[],"status_note":"Good condition","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.568597-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003569.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003569/8d96eb01dc-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003569/8d96eb01dc-1600.webp","licence":"CC BY-SA 3.0","author":"User:Ruhrfisch","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Buttonwood_Bridge_Panorama_1.jpg\" rel=\"noopener\">User:Ruhrfisch</a>, <a href=\"http://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:Buttonwood_Bridge_Panorama_1.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993362","wikipedia":"https://en.wikipedia.org/wiki/Buttonwood_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5003117"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lycoming-county/buttonwood-covered-bridge-80003569/"}
