It is a Town truss bridge 52 feet long between end posts.","why_significant":"The nomination argues the bridge is one of only four surviving covered bridges in Indiana County, a group that formerly numbered six. It is presented as a good example of wood-truss transportation technology within the county's covered bridge group, which is listed as a thematic resource.","narrative":"Built in 1879 over Crooked Creek in Armstrong Township, Indiana County, Pennsylvania, the Thomas Covered Bridge is a wooden structure with a Town truss system and a total length of 52 feet between end posts. It has vertical siding, a gable roof, and an open window area at the roofline, and its floor is laid with boards running across the span. The bridge is one of four surviving covered bridges in Indiana County, which formerly had six. The other three surviving bridges are the Trusal, Harmon's, and Kintersburg bridges, and all four are owned by the county and kept in good condition. Together they form a thematic group that illustrates the county's nineteenth-century timber bridge construction. Its significance rests on its typical wooden truss construction and its place within this small surviving set of covered bridges in the county.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":["C"],"status_note":"Good condition; all four county bridges are owned by the county and well maintained.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.898006-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002237.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002237/820b147090-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002237/820b147090-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:THOMAS_COVERED_BRIDGE.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ MD</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:THOMAS_COVERED_BRIDGE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993083","wikipedia":"https://en.wikipedia.org/wiki/Thomas_Covered_Bridge_(Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q7788659"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/indiana-county/thomas-covered-bridge-79002237/"}
