The I-74 bridge over the Mississippi River will be replaced, new highway ramps will be installed, and connecting roads will be reconfigured.
The I-74 bridge over the Mississippi River and local connecting roads in Bettendorf and Davenport, Iowa and Moline, Illinois.
Construction began in July 2017 and is expected to be complete in 2021.
The project is estimated at $1.2 billion.
The I-74 bridge traffic is overcapacity, leading to long delays and frequent need for repairs. A new bridge is needed to accommodate current and future traffic volumes.
