. This riveted cantilever through truss bridge has one of the more unusual designs of any Mississippi River bridge. Construction started in 1929 and was completed in 1931. The designer and chief engineer was Melvin B. Stone. The McClintic-Marshall Company of Chicago erected the trusses. The steel came from the Inland Steel Company. The Wisconsin approach has a long causeway over Winneshiek bottoms (sloughs, ponds, and backwaters) before ramping up to the bridge itself. The main shipping channel is on the Iowa side. The Iowa approach is rather abrupt, going from a city street straight up a steep ramp onto the bridge. Originally a privately built and operated bridge owned by the Iowa-Wisconsin Bridge Company, it was closed between 1945 and 1957, due to damage from ice damming, and lacking funds to repair the bridge, the company went out of business. The two states acquired the bridge and repaired it. In August 2011 the bridge was briefly closed for repairs after a crack was found in a floor beam.


Replacement

The bridge has a sufficiency rating of 39.9 percent, which mainly reflects its obsolete nature. The Iowa Department of Transportation is planning for a replacement bridge to start construction in 2024. It was revealed during a meeting on June 15, 2021, that the replacement bridge's design would look extremely similar to the current bridge's design while either retaining the pier's design or adopting a newer wave design.


In popular culture

The bridge was featured in a scene from the 1999 film
