The seemingly unrelated aims of functional strength and aesthetic appeal had been not only successfully integrated in many of the classic suspension bridges of the past two centuries but also commonly achieved by engineers alone or leading teams. Thomas Telford was in fact both engineer and architect of his Menai Suspension Bridge, and John Roebling was both engineer and architect of his Brooklyn Bridge That these engineering structures especially have come to be regarded as architectural icons demonstrates the aesthetic heights that an engineer can achieve.

Engineers less artistically confident than Telford and Roebling have engaged consulting architects to advise them on the design of everything from the facades placed on massive anchorages and skyscraper-high towers to the finishing details like deck railings and lampposts. Othmar Ammann, the chief engineer of the George Washington and many other New York City bridges. often sought the help of famous architects.

When the George Washington was but an idea on paper. Ammann engaged Cass Gilbert. the architect of the Woolworth Building and other landmarks, to depict how the towers might be finished in stone. Since money was tight when the bridge was being completed. however. the steel-framed- towers were left bare-a look that the Swiss architect Le Corbusier found extremely appealing-and bare steel became the new aesthetic standard for monumental bridge towers.
