It is one of a group of covered bridges in the two counties listed together as a thematic resource. The bridges are regarded as important examples of wood truss technology, a once-common bridge type that played a special role in its development. The county group has a comparatively high survival rate for this type of structure. The bridge is listed for its architectural value as a representative example of the Burr arch type, shown by the simplicity of its truss design and certain local features in its construction.","period_of_significance":null,"architect_builder":null,"architectural_style":"Burr arch truss","criteria":["C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.165225-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002354.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002354/798a92e247-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002354/798a92e247-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:HORN_DAVIS_OVERHOLTZER_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:HORN_DAVIS_OVERHOLTZER_BRIDGE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994051","wikipedia":"https://en.wikipedia.org/wiki/Horn_Davis_Overholtzer_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5903915"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/davis-horn-overholtzer-bridge-79002354/"}
