Monongahela River: the Hot Metal Bridge is in the foreground. It's actually two bridges in one, completed in 1887 and 1990. One portion is a former rail bridge and the other portion carried crucibles of molten steel from blast furnaces to rolling mills across the river. Today the spans carry automobiles and pedestrians. In the background is the Birmingham Bridge.
