Significance: Designed by Gustav Lindenthal, one of America's most famous bridge engineers, as a two-lane bridge. One lane was erected in 1883, and another was added in 1891. The span is Pittsburgh's most graceful and makes use of a double lenticular truss, patented in America by Edwin Stanley in 1851.
