I-74 Bridge

The I-74 Bridge is a twin suspension bridge that crosses the Mississippi River, linking Bettendorf, Iowa to Moline, Illinois. The structure features two separate traffic decks for vehicles and a shared pedestrian and bicycle path connecting the two states.

The Mississippi crossing in this location began in 1935 with a bridge designed by engineer Ralph Modjeski. A second bridge was added in 1959, and both were eventually replaced by today's structure.

The bridge serves as the backbone connecting Quad Cities communities on both sides of the Mississippi River, making daily life flow between states. Walking or driving across it, you experience how intimately linked these Iowa and Illinois towns have become through this crossing.

The bridge is open daily to vehicles, pedestrians, and cyclists with views of the river along the sides. You get the best sense of the structure by walking or cycling across, rather than driving, to notice the details and scale.

The shared pedestrian and bicycle path lets visitors experience the Mississippi from a perspective that drivers miss entirely. This route gives you time to sense the power and breadth of the river while moving between two states on foot.
