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

(Bridge Hunter, no Historic Bridges, Satellite)

The other long trestle bridge over the Des Moines River is still being used.

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.
