Built in 1874 and designed by James Buchanan Eads, the Eads Bridge was the first large bridge to span the Mississippi. It was the world's first alloy steel bridge and the first to depend entirely on cantilever in building the superstructure. The center span is 520ft. and the two end spans are 500ft. The bridge had two decks for traffic - the upper deck for pedestrians and vehicles and the lower deck for the railroad.
On the day I took this photo much of modern St. Louis and East St. Louis was masked by the fog making it easy to imagine what it would be like at the turn of the century down on the waterfront at the Gateway to the West.
