It is nominated under the Covered Bridges of Somerset County multiple property submission. The available text gives little further argument for significance beyond its construction type and the county group it belongs to.","narrative":"A covered timber bridge over Stony Creek in Quemahoning Township, about three-quarters of a mile southeast of Stoystown in Somerset County, Pennsylvania. It is a multiple kingpost truss with a timber deck 104 feet long, a width of 12 feet 6 inches and a clearance of 11 feet 6 inches. The gable roof is covered with asbestos shingles, and the half-height vertical plank siding that once enclosed the sides is largely missing. The stated date of construction is 1845, and the builder is unknown. The bridge is owned by the Stoystown Lions Club and carries Township Route 647 across the creek. It is closed to vehicles, with no load posted. The bridge is part of a group of covered bridges in Somerset County, a county that retained several examples of kingpost, queenpost and Burr arch construction. The bridge is listed for its place within that surviving group of nineteenth-century timber crossings.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Poor condition, with many vertical siding boards missing, woodrot in the bracing and worn deck planking; the bridge is closed to traffic.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.595441-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003636.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003636/ed85e631b2-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003636/ed85e631b2-1600.webp","licence":"CC BY-SA 3.0","author":"Allen C.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Trostletown_Bridge.JPG\" rel=\"noopener\">Allen C.</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:Trostletown_Bridge.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993871","wikipedia":"https://en.wikipedia.org/wiki/Trostletown_Bridge","wikidata":"https://www.wikidata.org/wiki/Q7846313"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/somerset-county/trostletown-bridge-80003636/"}
