The bridges are described as illustrating the once common bridge type in Pennsylvania and the simplicity of the truss types and local design features.","narrative":"Spanning Raccoon Creek in Raccoon Township, Washington County, Pennsylvania, the Lyle Covered Bridge is a queenpost truss structure with vertical board siding, a gable roof and cut stone abutments. Its side walls are pierced by three windows on each side, and the roadway is about twelve feet wide. The bridge belongs to a group of covered bridges in Washington and Greene Counties that together represent wood truss construction once common across Pennsylvania. Its simple truss design and local construction details are the basis for its inclusion in the group. The group is considered a comparatively high concentration of such structures in these rural counties. Two bridges moved from elsewhere in the group were relocated because of demolition threats, and the surviving structures remain in settings that suit their function. The bridge carries a posted weight limit of two tons.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition is not stated for this bridge in the excerpt; the form's bridge plate shows a 2 ton gross weight limit.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.934781-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79003831.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79003831/6cd72a8706-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79003831/6cd72a8706-1600.webp","licence":"CC BY-SA 4.0","author":"Lee Paxton (Original uploader was Leepaxton at en.wikipedia)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:LyleCoveredBridge.jpg\" rel=\"noopener\">Lee Paxton (Original uploader was Leepaxton at en.wikipedia)</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:LyleCoveredBridge.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994043","wikipedia":"https://en.wikipedia.org/wiki/Lyle_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q6707880"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/lyle-covered-bridge-79003831/"}
