Built in 1887, according to PennDOT records, it spans 166 feet with three semi-circular arches of 32 feet each, flanked by long approach walls. The structure is built of coursed rubble, with rock-faced ashlar voussoirs and contrasting parapet coping as its only decorative elements. Its stones above the arch crown are noticeably smaller than those below, suggesting the bridge was built in two phases. The bridge is regarded as a well-preserved example of multi-span stone bridges in the county. It retains its original site and remains unaltered, and it is grouped with two other stone bridges in Lehigh County built in the last quarter of the nineteenth century. Its significance lies in engineering, reflecting the typical design and construction of such crossings in the region during that period.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"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 17:11:36.328832-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/88000771.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/88000771/4242e0c97f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/88000771/4242e0c97f-1600.webp","licence":"Public domain","author":"PennDOT","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Frantz%27s_Bridge.jpg\" rel=\"noopener\">PennDOT</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Frantz%27s_Bridge.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993316","wikipedia":"https://en.wikipedia.org/wiki/Frantz%27s_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5492628"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lehigh-county/frantzs-bridge-88000771/"}
