It is one of three lenticular trusses in the nomination and differs in configuration from the two Lycoming County lenticular trusses. It is also considerably shorter than the two later Berlin Company lenticular trusses in the group.","narrative":"Spanning Tunkhannock Creek in rural Nicholson Township, Wyoming County, Pennsylvania, this single-span highway bridge was built in 1876, as recorded on its plaque. It is a steel lenticular truss, a form named for the lens-like curve of its upper and lower chords. The bridge was fabricated by the Corrugated Metal Company, the earlier name of the Berlin Iron Bridge Company of Berlin, Connecticut. It measures 110 feet overall and carries vehicular traffic across a crossing that remains in original use. Its significance rests on engineering: it is an early, largely intact example of an unusual truss type. Its configuration differs from the two lenticular trusses in Lycoming County, and it is shorter than the two later Berlin Company lenticular trusses included in the same group. The nominated area is a rectangle covering the bridge superstructure and substructure within the outer corners of its wing walls.","period_of_significance":"1876","architect_builder":"Corrugated Metal Company (builder/bridge company; the document identifies it as the early name of the Berlin Iron Bridge Company of Berlin, Connecticut)","architectural_style":null,"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 17:11:36.453632-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/88000810.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/88000810/5b7b047b86-800.webp","url_1600":"https://nationalhistoricalregister.com/media/88000810/5b7b047b86-1600.webp","licence":"CC BY-SA 2.0","author":"Adam Moss","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Pierceville_Bridge_-_March_2015.jpg\" rel=\"noopener\">Adam Moss</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Pierceville_Bridge_-_March_2015.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994081","wikipedia":"https://en.wikipedia.org/wiki/Bridge_in_Nicholson_Township","wikidata":"https://www.wikidata.org/wiki/Q4966367"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/wyoming-county/bridge-in-nicholson-township-88000810/"}
