C&NW Bridge over Des Moines River west of Boone, IA

(Bridge Hunter, no Historic Bridges, Satellite)

UPRR, 1901
Facebook posting of a W. H. Jackson photo from Shorpy allowed me to find the Kate Shelley Bridge. The steel girders were 7-feet deep. "The bridge was the longest and heaviest viaduct of its time, and may be the longest extant double-track railroad viaduct in the world. It is listed in the National Register of Historic Places." [Report of the Historic American Engineering Record]

It was built during 1899-1901 and bypassed during 2007-2009. There are several photos on UPRR's web page.
