It states that covered bridges were once a common bridge type in Pennsylvania and that these rural examples illustrate the type's construction technology through the simplicity of their truss types and local design features.","narrative":"Near Carmichaels in Greene County, Pennsylvania, the Carmichaels Covered Bridge crosses Muddy Creek on a queenpost truss built in 1889. The structure has vertical board and batten siding and a gable roof covered with raised seam tin. Its end posts measure 64 feet, and the road surface is 15 feet wide, with a recorded clearance of 13 feet. The bridge is one of several covered bridges surveyed in Washington and Greene Counties, where wooden covered spans were once a common form of bridge in Pennsylvania. Its inventory entry records its condition as good. The listing rests on its value as a representative example of that type, showing how a simple truss and local design details were used in rural counties to carry traffic across streams.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition recorded as good in the inventory entry.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:28.754262-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79003815.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79003815/20e73f456a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79003815/20e73f456a-1600.webp","licence":"CC BY 2.0","author":"Kathy from just livin' in a small town in SW PA, USA","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Carmichaels_Bridge.jpg\" rel=\"noopener\">Kathy from just livin' in a small town in SW PA, USA</a>, <a href=\"https://creativecommons.org/licenses/by/2.0\" rel=\"license noopener\">CC BY 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Carmichaels_Bridge.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993006","wikipedia":"https://en.wikipedia.org/wiki/Carmichaels_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5043670"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/greene-county/carmichaels-covered-bridge-79003815/"}
