It was constructed around 1871 by the Pennsylvania Railroad.","why_significant":"The nomination argues the bridge is one of only a few masonry arch railroad bridges in southern York County and one of four surviving bridges from the 1871 reworking of the line. It is said to be closely comparable to two other arch bridges on the same route. The line's role in linking southern and eastern York County to Baltimore and Philadelphia markets is also cited.","narrative":"Built around 1871 by the Pennsylvania Railroad, this single-span masonry arch bridge carries the Northern Central Railway over Route 616 and Codorus Creek in Shrewsbury Township. The arch uses rectangular granite voussoirs resting on granite imposts, with larger step-cut brownstone voussoirs set above them. Limestone ashlar forms the spandrels and abutments, and a projecting string course runs above the crown. The bridge was built during the widening of the line to lay a second set of tracks between Baltimore and York. It is one of four surviving bridges from that 1871 work, and few masonry arch railroad bridges remain in southern York County. The line linked farmers and merchants of southern and eastern York County to Baltimore and Philadelphia markets. The structure remains in use for freight and excursion trains and is described as being in good condition.","period_of_significance":"1871 - 1942","architect_builder":"Pennsylvania Railroad (builder)","architectural_style":"Masonry Arch Bridge","criteria":["A"],"status_note":"Still in use for freight movement and train excursions; the document states it is in good condition with historic integrity intact.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:36.071371-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/95000542.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/95000542/c943f560a7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/95000542/c943f560a7-1600.webp","licence":"CC BY-SA 3.0","author":"Purple pirouette","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Bridge_182%2B42,_Northern_Central_Railway,_Shrewsbury_Twp.,_PA,_Near_Town_Of_Railroad.jpg\" rel=\"noopener\">Purple pirouette</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:Bridge_182%2B42,_Northern_Central_Railway,_Shrewsbury_Twp.,_PA,_Near_Town_Of_Railroad.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994121","wikipedia":"https://en.wikipedia.org/wiki/Bridge_182%2B42,_Northern_Central_Railway","wikidata":"https://www.wikidata.org/wiki/Q4966198"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/york-county/bridge-182-42-northern-central-railway-95000542/"}
