One span is a through truss and the north end is a pony truss, with a wooden deck and stone abutments.","why_significant":"It is one of a group of surviving early metal truss highway bridges in Fulton County, nominated as part of a thematic collection covering 1883-1915. The collection reflects the improvement of the region's highway transportation through the replacement of fords, ferries and older bridges with up-to-date steel trusses. The bridges were also judged to retain their historic integrity.","narrative":"Bernadotte Bridge carries County Highway 2 at Bernadotte, in the vicinity of Smithfield, Fulton County, Illinois. Built in 1903, it has two steel spans of Pratt truss design: a through truss and a smaller pony truss at the north end. The bridge rests on stone abutments and has a wooden deck. The Central States Bridge Company of Indianapolis, Indiana, manufactured it, and the engineer is not recorded. The through span measures roughly 154 feet along the bottom chord, and the roadway is about 18 feet wide. The bridge was included in a thematic group of early metal highway bridges in Fulton County dating from 1883 to 1915. Together, these bridges show how local roads were improved as fords, ferries and older bridges gave way to modern steel trusses. The group also illustrates changes in steel bridge construction, particularly the Pratt and Parker truss types. The bridges were considered historically significant at the state level and largely unaltered.","period_of_significance":null,"architect_builder":"Central States Bridge Company, Indianapolis, Indiana (manufacturer); engineer unknown","architectural_style":"Pratt truss (through and pony)","criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.145927-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/42/8911/28891142/content/electronic-records/rg-079/NPS_IL/80001360.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80001360/f8d7c0ab92-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80001360/f8d7c0ab92-1600.webp","licence":"CC BY-SA 3.0","author":"Jacksdl","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Bernadotte_Bridge,_Bernadotte_Illinois.JPG\" rel=\"noopener\">Jacksdl</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:Bernadotte_Bridge,_Bernadotte_Illinois.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28891142","wikipedia":"https://en.wikipedia.org/wiki/Bernadotte_Bridge","wikidata":"https://www.wikidata.org/wiki/Q4892834"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/fulton-county/bernadotte-bridge-80001360/"}
