It measures 98.75 feet long, with a roadway 15.25 feet wide and 10 feet of clearance. The truss uses four diagonal beams on either side of a king post, with the arch superimposed on the truss. Its stone and mortar abutments were repaired with concrete only where needed, and no steel reinforcement was added to the undergirding or deck. The walls carry horizontal beveled boards, and the roof is lined with wooden shingles. The bridge was built by George Russell, Jr. Columbia County's covered bridges, including this one, are noted for their varied designs, which include king post, Warren, queen post, Burr and Howe trusses. The bridge served the county's growing towns and the farm and mill trade that depended on travel between them.","period_of_significance":null,"architect_builder":"George Russell, Jr. (builder)","architectural_style":"Theodore Burr arch truss","criteria":[],"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 17:11:33.448768-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79003195.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79003195/e730247b12-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79003195/e730247b12-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Wanich_C_Bridge_PA.jpg\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Wanich_C_Bridge_PA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992802","wikipedia":"https://en.wikipedia.org/wiki/Wanich_Covered_Bridge_No._69","wikidata":"https://www.wikidata.org/wiki/Q7967939"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/columbia-county/wanich-covered-bridge-no-69-79003195/"}
