QUAD CITIES, IA AND IL – The westbound span of the I-74 Mississippi River bridge has been selected to receive the 2022 Prize Bridge Award in the “Major Span” category from the America Institute of Steel Construction and the National Steel Bridge Alliance. Offering increased capacity, safety and access through the Quad Cities region on I-74, the structure was chosen for its innovative use of structural steel and its benefit to the public.
Benesch served as Corridor-Wide Coordinator on behalf of the Iowa and Illinois DOTs and led design plans for the extended Central Sections of the project, which included the substructures that support the Modjeski & Masters-designed twin arch superstructure as well as the approach span superstructures and substructures at either end of the bridge.
The win was announced in the July issue of Modern Steel Construction magazine. The project’s structural experts, including Benesch Illinois Division Manager Andrew Keaschall, recently shared their insight on the project’s unique true arch design and other structural features with KWQC TV.
