The Interstate 74 Bridge, officially known as the Iowa-Illinois Memorial Bridge, and often called The Twin Bridges, or the I-74 Bridge, are basket-handle, through arch twin bridges that carry Interstate 74 across the Mississippi River and connect Bettendorf, Iowa, and Moline, Illinois. It is located near the geographic center of the Quad Cities. They replace two suspension bridges opened to traffic in 1935 and 1959, both of which had become obsolete by the 1990s.
