It was constructed in 1900 by the Pennsylvania Railroad Company.","why_significant":"The nomination argues the bridge is significant as an example of the riveted girder type of railroad bridge and as part of the Northern Central Railway, which linked southern and eastern York County to Baltimore and Philadelphia markets. Its five girders, where comparable bridges in the county have two, and its stone abutments, which may survive from an earlier trestle, are cited as reflecting at least two periods of railroad construction. It is described as being in good condition with much of its historic integrity retained.","narrative":"Bridge 5+92 is a single-span riveted steel girder deck railroad bridge in the borough of Seven Valleys, York County, Pennsylvania, where it carries the Northern Central Railway over Main Street. The Pennsylvania Railroad Company built it in 1900, and it was designed for a double track although only one set of rails remains. Five riveted steel girders rest on stepped abutments of large granite ashlar, which also retain the railroad grade. The abutments may be original to a trestle bridge built when the line was first laid, so the structure may reflect at least two periods of railroad construction. The Northern Central Railway linked the farms and merchants of southern and eastern York County to the Baltimore and Philadelphia markets from the mid-nineteenth century onward. The bridge is important as a representative example of the riveted girder type of railroad bridge. Its five-girder arrangement differs from the two-girder design common among other York County bridges. The structure is in good condition and retains much of its historic integrity.","period_of_significance":"1900-1942","architect_builder":"Pennsylvania Railroad Company (builder)","architectural_style":null,"criteria":["A","C"],"status_note":"The bridge remains in use through periodic freight movement and train excursions and is in good condition.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:37.591381-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/95000548.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/95000548/b7c78d559a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/95000548/b7c78d559a-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:7_Valleys_PA_RR_bridge_from_N.JPG\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:7_Valleys_PA_RR_bridge_from_N.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994119","wikipedia":"https://en.wikipedia.org/wiki/Bridge_5%2B92,_Northern_Central_Railway","wikidata":"https://www.wikidata.org/wiki/Q4966200"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/york-county/bridge-5-92-northern-central-railway-95000548/"}
