It is one of fifteen bridges of this type included in the nomination.","why_significant":"The nomination describes the bridge as a representative example of the open-spandrel arch type. Its molded decorative elements on arch ribs, spandrel posts, brackets, rails and transverse arches are presented as a continuation of attractive concrete design in Pennsylvania highway bridges. The form describes it as finely ornamented and well preserved, and argues it warrants listing under the Engineering area of significance.","narrative":"Whitehall Township's Cold Spring Bridge is a concrete open-spandrel arch carrying vehicular traffic across Spring Creek on Second Street. Completed in 1930 and built by Dawes & Norris, the single span measures 160 feet and is flanked by approach spans totaling four spans of 17 feet each. Six symmetrically placed spandrel arches open the structure above the arch ribs. Its arch ribs, spandrel posts, brackets, concrete rails and transverse arches are all molded into simple decorative shapes, a level of ornament the nomination treats as unusual for this bridge type. The bridge is considered a representative example of open-spandrel arch construction and a continuation of concrete design traditions in Pennsylvania highway bridges. It is regarded as finely ornamented and well preserved. Its listing is grounded in engineering significance, and it is one of fifteen bridges of this type evaluated together as part of a multiple-resource group of Pennsylvania Department of Transportation highway bridges.","period_of_significance":"1930","architect_builder":"Dawes & Norris (builder/contractor)","architectural_style":null,"criteria":[],"status_note":"Unaltered, original site, in use for vehicular traffic","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:36.425842-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/88000874.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/88000874/117069212c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/88000874/117069212c-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Cold_Spring_Bridge_Lehigh_Co_PA.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:Cold_Spring_Bridge_Lehigh_Co_PA.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993322","wikipedia":"https://en.wikipedia.org/wiki/Cold_Spring_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5142347"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lehigh-county/cold-spring-bridge-88000874/"}
