It is one of only three metal truss bridges left in Champaign County and the only one with approach spans over a river overflow area. Its cast iron or steel cruciform column bents are described as possibly the only known example in Illinois.","narrative":"Spanning the Sangamon River four miles north of Mahomet, this sixteen-span bridge carries a township road across a wide, flood-prone river bottom. Champaign County commissioners chose the Seevers Manufacturing Company of Oskaloosa, Iowa, to build it in 1893 at the site of White Ford, for a bid of $4,985. A 120-foot pin-connected Pratt through truss forms the main span, flanked by timber-decked approach spans that carry the road over the overflow area. Those approaches rest on pier bents of three cruciform cast iron or steel columns, a support system described as possibly the only one of its kind in Illinois. Open construction let floodwater pass through instead of backing up. The bridge is one of only three metal truss bridges left in the county and the only one with approach spans. It is named for the Hazen family, who owned land west of the crossing, and it retains a high degree of integrity.","period_of_significance":"1893","architect_builder":"Seevers Manufacturing Company/Builder","architectural_style":"OTHER: Pratt through truss","criteria":["C"],"status_note":"Structural integrity is intact and the bridge is posted for a three ton load limit. A new bridge is being built to the south, and the historic bridge is to pass to a preservation association once it is vacated.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.353138-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/38/8918/28891838/content/electronic-records/rg-079/NPS_IL/94000433.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/94000433/c651bae80b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/94000433/c651bae80b-1600.webp","licence":"Public domain","author":"Roger McCredie","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hazen_Bridge.jpg\" rel=\"noopener\">Roger McCredie</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Hazen_Bridge.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28891838","wikipedia":"https://en.wikipedia.org/wiki/Hazen_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5688240"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/champaign-county/hazen-bridge-94000433/"}
