While studying the location of a couple of depots in Muscatine, IA, I noticed the Mississippi River bridge moved. It used to be an extension of Walnut Street.

When I read in the Bridge Hunter facts that the width of the deck was 18 feet, I checked the width of the Hummer Bridge, which I know is a scary bridge because it is skinny and high. The Hummer is 19.7 feet wide. The new bridge is also just two lanes, but its deck width is 32 feet. So I'll bet the local residents were glad to switch to the new bridge and see the skinny bridge demolished in 1973.
The 1972 Norbert F. Beckey replacement bridge has a through steel truss for the 500-foot wide navigation channel with a clearance of 65 feet. The rest of the spans are steel girders.
