I-74 Mississippi River bridge named #1 Bridge of 2022
The new I-74 Mississippi River bridge in the Quad-Cities – which resulted in IMEG’s largest civil engineering project – has been named Roads & Bridges Magazine’s #1 Bridge of 2022.
Designed by Alfred Benesch and Modjeski and Masters, the 3,400-feet-long span provides a crossing over the Mississippi River between Bettendorf, Iowa, and Moline, Ill. The new structure features dual basket-handle arch bridges with main channel spans of 800 feet. There are six lanes, including a bicycle and pedestrian path.
The overall Interstate 74 Bridge Corridor Project included replacing the old bridge and improving about eight miles in the I-74 corridor.
IMEG provided construction engineering, materials testing, and inspection for multiple components of the project.
