The Eads Bridge is a bridge over the Mississippi River connecting the cities of St. Louis, Missouri, and East St. Louis, Illinois. 
Work on the bridge began in 1867, and it was completed in 1874. The Eads Bridge was the first bridge across the Mississippi south of the Missouri River. None of the earlier bridges survived, which means that the Eads Bridge is also the oldest bridge on the river.
