Rock Island Centennial Bridge

The Rock Island Centennial Bridge extends 4,447 feet across the Mississippi River with five steel arches connecting Davenport, Iowa to Rock Island, Illinois.

The bridge opened on July 12, 1940, as the first four-lane highway structure over the Mississippi River, constructed at a cost of 1.75 million dollars.

The bridge lighting system installed in 1988 contains 128 sodium lamps that create reflections on the Mississippi River during evening hours.

The bridge serves as a motor vehicle crossing point between Iowa and Illinois, with no toll fees required since 2003 for passage across the Mississippi.

The structure features independent tied arch designs for each span, employing 9,750 tons of steel supported by six concrete piers and steel H-piles.
