Healthy, built in 1850 by Jediah Hill. It is a 3-panel Queenpost truss bridge on stone abutments.","why_significant":"The nomination notes it is the only remaining covered bridge in Hamilton County and one of about half a dozen Queenpost truss covered bridges left in Ohio. It is tied to the builder Jediah Hill and is still used as the sole access to a residential community. Local residents raised funds for its restoration in the 1950s.","narrative":"Built in 1850 by Jediah Hill, this covered wooden bridge crosses a stream in Springfield Township, Hamilton County, about a mile north of Mt. Healthy. It is a three-panel Queenpost truss with oak trusses resting on stone abutments with curved wing walls. The original span was nearly 45 feet, with roughly 12 and a half feet of width clearance. Hill also built a flour mill a few hundred feet to the northeast. After knee braces were removed to admit larger vehicles, the roof collapsed under heavy snow in January 1956. The bridge was then restored with a concrete center pier, steel I beams beneath the trusses, new siding, a wood shake roof and preservative-treated timbers. It is the only covered bridge left in Hamilton County and one of about six Queenpost truss covered bridges remaining in Ohio. It still serves as the only access to a community of nearly a hundred homes, and local people have long supported its preservation.","period_of_significance":"1850 (19th Century)","architect_builder":"Jediah Hill (1773-1859)","architectural_style":"3-panel Queenpost truss covered bridge","criteria":[],"status_note":"Described as in good condition and still in use; restored after a roof collapse in January 1956, with a concrete center pier and steel I beams added under the original trusses.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:10.21952-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/73001460.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/73001460/4527e1b98c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/73001460/4527e1b98c-1600.webp","licence":"CC BY-SA 3.0","author":"Photo by Greg Hume (Greg5030)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:JediahHillBridge.jpg\" rel=\"noopener\">Photo by Greg Hume (Greg5030)</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:JediahHillBridge.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71989217","wikipedia":"https://en.wikipedia.org/wiki/Jediah_Hill_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q6172784"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/hamilton-county/hill-jediah-covered-bridge-73001460/"}
