Benjamin G. Humphreys Bridge [SEP] History
The Works Progress Administration agreed to the proposal in September 1938 and construction started on the bridge a few months later. The Benjamin G. Humphreys Bridge was built by the company now known as HNTB and opened to much fanfare in 1940 as the "pathway to progress" for the Mississippi Delta. It was a through-truss design and had a span of 840 feet (256 meters). Until 1943, this was the longest bridge for vehicles on the Mississippi River. Over time, the bridge supported increasing volumes of highway traffic and vehicles hitting the bridge. In the 1950s, an Air Force plane crashed into the bridge.
