The bridge is described as having vertical siding, a tin-covered gable roof and sidewall windows, and the document notes a petition for a bridge at this site in 1865 though it may be a later structure.","narrative":"Jackson's Mill Covered Bridge crosses Kings Creek near Burgettstown in Washington County, Pennsylvania. It is a queenpost truss bridge with an end post length of 35 feet and a road surface about 14 feet wide. Its walls are vertical wood siding, the gable roof is covered in tin, and sidewall windows light the interior. Some of the side paneling has been lost, and the bridge is rated in fair condition. A petition for a bridge at this crossing was filed in 1865, although the surviving structure may be a later replacement. The bridge is one of a group of covered bridges in Washington and Greene Counties grouped together for listing. The group is regarded as a representative collection of wooden covered bridge construction, a type once widespread across Pennsylvania, and the bridges retain the simple framing and local design features typical of rural construction in the region.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition recorded as fair; some side paneling is missing.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.591975-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79003830.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79003830/74c8474cb8-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79003830/74c8474cb8-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Jackson%27s_Mill_Covered_Bridge,_eastern_portal_and_southern_side.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Jackson%27s_Mill_Covered_Bridge,_eastern_portal_and_southern_side.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994041","wikipedia":"https://en.wikipedia.org/wiki/Jackson%27s_Mill_Covered_Bridge_(Washington_County,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q1518067"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/jacksons-mill-covered-bridge-79003830/"}
