The structure dates to 1858 and was rebuilt in 1882. It measures about 108 feet between end posts, is 17 feet wide, and has a clearance of 11 feet 6 inches. Its walls are finished in vertical siding, and it rests on stone abutments. Steel reinforcements were added in recent years to strengthen the timber framing. The bridge is listed as part of a group of covered bridges in the Delaware River watershed. Its importance lies in the way it illustrates nineteenth-century wooden bridge construction. The Burr arch system, which combined an arch with a truss, was widely used for bridges of this size in the region. The surviving structure gives a clear example of that engineering tradition in Lehigh County.","period_of_significance":null,"architect_builder":null,"architectural_style":"Burr arch truss","criteria":[],"status_note":"Condition given as good; steel reinforcements were added in recent years.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.32994-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003559.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003559/6b89ec7ef3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003559/6b89ec7ef3-1600.webp","licence":"CC BY-SA 3.0","author":"Pma03","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Manasses_Guth_Bridge_(1858).png\" rel=\"noopener\">Pma03</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:Manasses_Guth_Bridge_(1858).png"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993330","wikipedia":"https://en.wikipedia.org/wiki/Manasses_Guth_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q6747032"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lehigh-county/manasses-guth-covered-bridge-80003559/"}
