It spans the South Branch of Roaring Creek in the nomination's listing.","why_significant":"The nomination treats the bridge as one of seven surviving covered bridges in Northumberland County that illustrate 19th-century wooden bridge technology and its role in developing transportation networks. It is also noted for its careful relocation and rebuilding, with repairs kept in harmony with the original structure.","narrative":"A modified queenpost truss covered bridge built in 1875, first over West Creek near Benton, Pennsylvania. When road re-location bypassed it in 1936, it was sold to Knoebel's Grove, where it was taken apart and reassembled after timbers were moved about fifty miles. Five men spent a week dismantling it and another week rebuilding it. Wide boards were milled specially for the work, and the bridge is kept unpainted, with repairs using wooden shingles and matching original construction. The underside has been treated against insects and dampness. It is listed as one of seven surviving covered bridges in Northumberland County that show 19th-century wooden bridge technology and its part in developing local transportation routes. The bridge was dedicated in 1964 by the Theodore Burr Covered Bridge Society of Pennsylvania, which honored the Knoebel family for its preservation, and it was named for Lawrence L. Knoebel.","period_of_significance":"1875","architect_builder":null,"architectural_style":"Modified queenpost truss","criteria":["C"],"status_note":"Condition recorded as good; bridge rebuilt at Knoebel's Grove after relocation and dedicated in 1964.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:28.970253-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002309.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002309/fff805dd2c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002309/fff805dd2c-1600.webp","licence":"CC BY-SA 4.0","author":"Ruhrfisch","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Lawrence_L._Knoebel_Covered_Bridge_1.JPG\" rel=\"noopener\">Ruhrfisch</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:Lawrence_L._Knoebel_Covered_Bridge_1.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993426","wikipedia":"https://en.wikipedia.org/wiki/Lawrence_L._Knoebel_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q6504290"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/northumberland-county/knoebel-lawrence-l-covered-bridge-79002309/"}
