It has wrought iron trusses on masonry abutments.","why_significant":"The nomination argues the bridge is a significant transportation link, built in 1889 to replace a wooden span destroyed by flood. It is described as the last wrought iron Phoenix bridge in extensive use in the local area. The design is credited as an efficient, well-built use of Phoenix column sections and eye-bar tension members.","narrative":"Built in 1889 across Yellow Breeches Creek, the Etters Bridge is a single-lane, simple-span Pratt through truss with wrought iron trusses resting on stone and concrete abutments. It replaced a wooden bridge that floods had destroyed in May and June of that year. The Cumberland County Commissioners selected Dean and Westbrook, a New York City firm of bridge engineers and contractors, to build the new span. The superstructure was procured from the Phoenix Bridge Company and its parent, the Phoenix Iron Company, of Phoenixville, Pennsylvania, and uses patented Phoenix column sections for its compression members. The bridge linked the mill community of Milltown on the Cumberland County side with farms and businesses on the York County side. Its main significance lies in its engineering and its role in local transportation. Most of the deck was replaced around 1960 with steel grid, and guard rails were added in 1976. The bridge still carries an average daily traffic of 2000 or more vehicles.","period_of_significance":"1889","architect_builder":"Dean and Westbrook (builder/contractor), New York City","architectural_style":"Pratt truss","criteria":["C"],"status_note":"Still carrying traffic; posted for a 15 ton load limit; altered with a steel deck and guard rails.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.361752-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/86000308.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86000308/b79e2c4f2c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86000308/b79e2c4f2c-1600.webp","licence":"CC BY-SA 3.0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Green_Lane_Bridge_York_n_Cumberland_PA_3.JPG\" rel=\"noopener\">Smallbones</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:Green_Lane_Bridge_York_n_Cumberland_PA_3.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996317","wikipedia":"https://en.wikipedia.org/wiki/Etters_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5404999"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/cumberland-county/etters-bridge-86000308/"}
