I-74 Bridge Replacement Project—Moline, Ill. to Bettendorf, Iowa

The state line intersection of Illinois and Iowa is banded by the Mississippi River. In the Quad Cities region, a pair of dated structures, linking Moline, Ill. and Bettendorf, Iowa via I-74, have been carrying more than 75,000 vehicles per day, a figure that is expected to grow to 100,000 by the year 2035. In a joint effort, the Iowa and Illinois Departments of Transportation are in the process of erecting a new I-74 crossing adjacent to the old one that will offer more capacity and better travel times. In addition to the bridge itself, the project includes interchange ramp reconfigurations and local roadway improvements. Construction began in July 2017 and is anticipated to take place over 3.5 years.
