It also relates to transportation, since bridges were needed to link towns with the farms and saw and grist mills that drove local business.

It measures 56.4 feet long, with a roadway 14 feet wide and a clearance of 11 feet. Its structure is a Queen Post truss, supplemented by iron tension rods running from the tops of the diagonal beams to the deck, found on only one end of each truss. The roof is tarred metal panels resting on thin wooden ribs over the rafters. The portals are covered with vertical planks, and the side walls use board and batten construction, with some areas of plain vertical planks. The deck combines horizontal and diagonal boards beneath two runways, with an iron tension rod and two longitudinal beams added beneath the center. Oak, pine and hemlock were the usual lumber for bridges of this kind. The bridge is significant for its engineering, as a surviving Queen Post truss in a county where covered bridges have not been built for half a century. It also reflects the need for crossings linking growing towns with farms and mills. Much of the abutments has been replaced by concrete.","period_of_significance":null,"architect_builder":"Dan Kostenbauder (builder)","architectural_style":null,"criteria":[],"status_note":"Much of the abutments have been replaced by concrete, and remaining stone areas are in need of repair.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.437924-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79003178.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79003178/0272d583bf-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79003178/0272d583bf-1600.webp","licence":"CC BY-SA 3.0","author":"Ruhrfisch","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Wagner_Covered_Bridge_5.jpg\" rel=\"noopener\">Ruhrfisch</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:Wagner_Covered_Bridge_5.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992836","wikipedia":"https://en.wikipedia.org/wiki/Wagner_Covered_Bridge_No._19","wikidata":"https://www.wikidata.org/wiki/Q7959601"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/columbia-county/wagner-covered-bridge-no-19-79003178/"}
