Its high side walls block direct view of the trussing system, leaving open windows beneath the eaves, and cross bracing is used on the roof. Steel pillars have been added as bracing. The bridge is one of fourteen surviving covered bridges in Bedford County that were grouped together in a multiple property listing. Its significance lies in its construction method, which represents wood bridge technology of the 19th century, when such bridges were common throughout the county. The bridge is regarded as an example of this transportation type, and its design and engineering are valued for their historical and visual qualities. The condition is recorded as excellent.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":["C"],"status_note":"Condition described as excellent.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.462886-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003412.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003412/ce190f7322-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003412/ce190f7322-1600.webp","licence":"CC BY 2.0","author":"Frank Kovalchek","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Snooks_Covered_Bridge_1.jpg\" rel=\"noopener\">Frank Kovalchek</a>, <a href=\"https://creativecommons.org/licenses/by/2.0\" rel=\"license noopener\">CC BY 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Snooks_Covered_Bridge_1.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992280","wikipedia":"https://en.wikipedia.org/wiki/Snooks_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q7547963"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bedford-county/snooks-covered-bridge-80003412/"}
