It also links the bridge to transportation needs during the rapid growth of towns and to farming and mill activity that depended on crossings.","narrative":"Stillwater Covered Bridge No. 134 is a wooden covered bridge in Stillwater, Columbia County, Pennsylvania, measuring 151.1 feet long with a roadway 15.25 feet wide. It is built on the Burr Truss Arch principle, with seven diagonal braces on each side of each truss system. The roof is galvanized steel laid over thin slats that cross the rafters, and the walls are board and batten. A window pierces one wall where the road curves sharply, and one column slants inward to improve sightlines at that bend. The floor is herringbone without runways, and no steel beams were added to the deck or undergirding. One abutment has been rebuilt in concrete, while the others remain original stone and mortar. The bridge is significant for its engineering, as covered bridges of this design have not been built in Columbia County in the last half century. It also reflects the transportation needs of growing towns and the farm and mill businesses that relied on river crossings. Oak, pine and hemlock were the usual lumber for these bridges.","period_of_significance":null,"architect_builder":"James McHenry (Foreman) John Edson","architectural_style":"Burr Truss Arch","criteria":["A","C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.783628-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79003177.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79003177/3e301d401b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79003177/3e301d401b-1600.webp","licence":"CC BY-SA 2.0","author":"Doug Kerr","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Stillwater_Covered_Bridge_-_Pennsylvania.jpg\" rel=\"noopener\">Doug Kerr</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Stillwater_Covered_Bridge_-_Pennsylvania.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992812","wikipedia":"https://en.wikipedia.org/wiki/Stillwater_Covered_Bridge_No._134","wikidata":"https://www.wikidata.org/wiki/Q7617286"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/columbia-county/stillwater-covered-bridge-no-134-79003177/"}
