It was built in 1891.","why_significant":"The nomination argues the bridge is a fine example of a small suspension bridge in Pennsylvania, where such bridges are relatively rare and the most important ones are in Pittsburgh and Philadelphia and are much larger. It was built as a replacement after a June 1890 flood destroyed the area's bridges, and it is linked to the engineering firm Dean & Westerbrooke, who also designed the Walnut Street Bridge at Harrisburg.","narrative":"Built in 1891 across Pine Creek at English Center in Lycoming County, this suspension bridge carries Legislative Route 41021 over a deep, wide ravine in mountainous country. It replaced crossings lost in a flood that swept through the village and destroyed the area's bridges and many homes. The bridge has a single 300-foot span with steel towers of plate and lattice work, eye-bar main members, and a continuous girder suspended from them. It has an under-clearance of 12 feet and an open steel deck 15 feet wide, with crossbracing in each panel for stiffness. The bridge was designed and built by Dean & Westerbrooke, engineers and contractors of New York, who also designed the Walnut Street Bridge at Harrisburg. Its importance lies in its engineering: it is regarded as a fine example of a small suspension bridge in Pennsylvania, a type otherwise found mainly in large examples at Pittsburgh and Philadelphia.","period_of_significance":"1891","architect_builder":"Dean & Westerbrooke (engineers and contractors of New York)","architectural_style":null,"criteria":["C"],"status_note":"Condition marked as good on the form.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.50623-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/78002428.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78002428/06046564e6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78002428/06046564e6-1600.webp","licence":"Public domain","author":"Joseph Elliott","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Haer-pa-461-photo03.jpg\" rel=\"noopener\">Joseph Elliott</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Haer-pa-461-photo03.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995471","wikipedia":"https://en.wikipedia.org/wiki/English_Center_Suspension_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5378202"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lycoming-county/english-center-suspension-bridge-78002428/"}
