The builder is not known.","why_significant":"The bridge has an unusually shallow queenpost truss that gives it the look of a Burr arch truss. It is the only covered bridge in Clinton County and is described as a rare adaptation of a common Pennsylvania covered bridge type. It belongs to a period when Pennsylvania had many covered bridges across its waterways.","narrative":"A covered bridge built in 1874 that spans Fishing Creek, a tributary of the West Branch of the Susquehanna River, in Clinton County near Loganton. It has a single 55-foot span carried on stone abutments, with a gable roof over a 12-foot-wide timber deck that is covered with gravel and limited to four tons. Its queenpost truss is unusually shallow, about six to eight feet deep, and the connecting crosspiece sits five to six feet below the top chord, which gives the bridge the look of a Burr arch truss. The builder is not known, and the shallow truss is considered unstable, so a wooden brace was added under one post. It is the only covered bridge in Clinton County and is regarded as a rare variation on a common Pennsylvania type. It belongs to a group of Pennsylvania covered bridges that were once numerous across the state's rivers and creeks. The bridge is in excellent condition.","period_of_significance":"1874","architect_builder":null,"architectural_style":"Queenpost truss","criteria":[],"status_note":"Described as in excellent condition.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.241762-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002213.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002213/b54a1689e4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002213/b54a1689e4-1600.webp","licence":"CC BY-SA 3.0","author":"Ruhrfisch","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Logan_Mills_Covered_Bridge_4.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:Logan_Mills_Covered_Bridge_4.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996305","wikipedia":"https://en.wikipedia.org/wiki/Logan_Mills_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q12061357"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/clinton-county/logan-mills-covered-bridge-79002213/"}
