Ashton. It crossed the Iowa River in Iowa City.[1] In 1989 it was demolished and replaced with a modern highway bridge. A historical marker nearby describes the old bridge. Ned Ashton has been called "the most distinguished bridge engineer in the history of Iowa and was a professor of civil engineering at the University of Iowa from 1943 to 1957. He designed several bridges over the Mississippi River, and was a pioneer in the design of welded plate girder bridges.[2][3] References1. ^Historic American Engineering Record HAER IOWA,52-IOWCI,4-, http://hdl.loc.gov/loc.pnp/hhh.ia0198 {{coord|41|39|2.32|N|91|32|20.47|W|region:US|display=title}}{{Iowa-bridge-struct-stub}}2. ^Benton Street Bridge, Historic American Engineering Record, Library of Congress. 3. ^Edward L.
