Blaney, who once owned land east of the bridge. The form lists it as built in 1882 and in good condition.","why_significant":"The nomination presents the bridge as one of the covered bridges in Washington and Greene Counties that illustrate a once-common bridge type in Pennsylvania, and that represent the development of wood truss technology. The form notes a comparatively high survival rate for these structures in these rural counties. It is listed as part of a multiple-property group of covered bridges.","narrative":"Near Claysville in Washington County, Pennsylvania, the Mays, or Blaney, Covered Bridge carries a road across Middle Wheeling Creek in Donegal Township. It is a queenpost truss bridge, a type of timber truss in which two vertical posts support the span. The form gives its end post length as 31 feet 6 inches and its road surface width as 11 feet 10 inches, and records its construction date as 1882. The bridge was once known as the Blaney Covered Bridge, named for J. Blaney, who owned land east of the crossing. It is grouped with other covered bridges in Washington and Greene Counties that were judged to illustrate a once-common Pennsylvania bridge type and the development of wood truss construction. Its condition is recorded as good, and the rural counties where these bridges survive have a comparatively high survival rate for structures of this kind.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":["C"],"status_note":"Condition described 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 17:11:30.868333-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002350.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002350/8d6d0c1b26-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002350/8d6d0c1b26-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:BLANEY_MAYS_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:BLANEY_MAYS_COVERED_BRIDGE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994015","wikipedia":"https://en.wikipedia.org/wiki/Blaney_Mays_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q4925058"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/mays-blaney-covered-bridge-79002350/"}
