It was previously included within the Vesuvius Furnace boundary, but it is thematically unrelated to the furnace. Flood damage in 2010 destroyed its integrity, so the form requests removing it from the boundary.","narrative":"A small stone-faced bridge carries a road over Storms Creek in the Vesuvius Recreation Area near Ironton, Ohio. The WPA built it in 1940 with Lawrence County and the U.S. Forest Service, using two corrugated metal arches topped with concrete and faced in sandstone and mortar for appearance. It measures 52 feet long and 22 feet wide. The Ohio Department of Transportation widened and refaced it in 1990, removing an original ledge. The bridge was valued as an unusual Depression-era public works project that used stone decoratively rather than structurally, and it provided jobs for unemployed Ohio workers. It was earlier included in the boundary of the Vesuvius Iron Furnace, though it was built 36 years after the furnace stopped operating and has no thematic link to it. A July 2010 flood eroded a footer and collapsed the western side, leaving damage that cannot be repaired. Its boundary was therefore reduced to exclude the bridge and an access road.","period_of_significance":"1940","architect_builder":"WPA","architectural_style":"No specific architectural or engineering style (classified as OTHER)","criteria":[],"status_note":"Flooding in July 2010 undermined the northwest footer and collapsed the western side; the bridge continues to sink and is described as beyond repair.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:07.576227-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/11000671.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71989649","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/lawrence-county/vesuvius-furnace-stone-bridge-boundary-decrease-11000671/"}
