Built in 1888, it is a kingpost truss bridge with an end post length of 31 feet 8 inches and a road surface width of 15 feet. It has vertical plank siding, a gable roof covered with raised seam tin, and cut stone block abutments. The bridge is one of a group of covered bridges in Washington and Greene Counties documented together as a multiple property submission. Its place in that group rests on its wood construction and simple local design, which the nomination treats as representative of covered bridge building in rural southwestern Pennsylvania. The surviving group, including this bridge, shows how wooden truss technology was applied to highway crossings in the region during the late nineteenth century. At the time of the record its condition was described as fair.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition recorded as fair.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.074174-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79003820.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79003820/0c2e9ea399-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79003820/0c2e9ea399-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:GRIMES_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:GRIMES_COVERED_BRIDGE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993002","wikipedia":"https://en.wikipedia.org/wiki/Grimes_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5609245"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/greene-county/grimes-covered-bridge-79003820/"}
