It has a Burr-type truss built of spliced white pine and is known locally as the Hassenplug Bridge after a family of brewers and farmers who lived on the creek at the site. The original bridge is dated to 1825. In 1959 the Union County Commissioners overhauled it, replacing the wooden floor with an iron grill, renewing the siding and installing gutters and downspouts, and the contractors named for that work were Kauffman, Naugle and Sheridan. A central pier and steel underpinning were added to support heavy traffic. The bridge sits at a bend in the creek and has long attracted artists. It is one of two surviving covered bridges on Buffalo Creek, and its Burr truss design and long service as a crossing are the main reasons it was recognized for architectural and transportation significance.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Burr truss","criteria":["C"],"status_note":"Original covered bridge dates to 1825; overhauled by the County Commissioners in 1959 with a steel-underpinned central pier and iron grill floor; wood covering in good condition and well painted; carries heavy traffic.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.174028-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003641.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003641/5de14df6c9-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003641/5de14df6c9-1600.webp","licence":"CC BY-SA 4.0","author":"User:Ruhrfisch","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hassenplug_Covered_Bridge.jpg\" rel=\"noopener\">User: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:Hassenplug_Covered_Bridge.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993897","wikipedia":"https://en.wikipedia.org/wiki/Hassenplug_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5680035"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/union-county/hassenplug-bridge-80003641/"}
