The $850 million Interstate 74 Bridge Corridor project included a new eight-lane span over the Mississippi River that connects the Illinois and Iowa sides of the Quad Cities and the supporting bridge approaches, ramps, and highway connections. The City of Moline and Renew Moline are currently meeting with developers and weighing the best options for the land where the former bridge once stood. Some potential ideas are mixed-use retail and also a green space component with recreation.
The realignment forms a fluid, safe, and highly-functioning river crossing; one that increases the capacity of motor vehicles and pedestrians traveling across the Mississippi River.
This bi-state public transportation project was managed by both the Illinois and Iowa Departments of Transportation (IDOT).
Funding for the project was provided by federal and state sources. The funding was implemented in stages over a multi-year period.

A Basket Handle True Arch Twin Bridge design was selected by the communities of Moline, Davenport, and Bettendorf and the two state IDOTs as the most appropriate style for the river span. This bridge will become an iconic landmark of the entire region.
The I-74 Realignment plan called for three lanes of traffic in each direction, with one additional lane used for emergency vehicles. The new passing is much safer and aesthetically appealing than the antiquated, century-old structure. Along with the increased lanes of traffic, a bike path is included in the project connecting Moline’s bike paths with those of Bettendorf.
The bridge was completed in early 2022.
