Built in 1875, it is a kingpost truss bridge with a length of 27 feet 6 inches and a road surface width of 12 feet 7 inches. Its sides are vertical board siding under a tin-covered gable roof, and square windows are cut into each sidewall. The bridge is one of a group of covered bridges in Washington and Greene Counties that together illustrate the wood truss technology once common across Pennsylvania. The group is valued because a comparatively high share of these bridges has survived in these rural counties. The structure's simple truss type and local design features give it a place in that record of regional construction. The surviving bridge is recorded in good condition.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition recorded as good.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.799228-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002365.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002365/99714644f7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002365/99714644f7-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Sprowl%27s_Covered_Bridge.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Sprowl%27s_Covered_Bridge.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994003","wikipedia":"https://en.wikipedia.org/wiki/Sprowl%27s_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q7581376"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/sprowls-covered-bridge-79002365/"}
