Bridge Cable Sample
1928
Suspending the George Washington Bridge
Three feet in diameter and 10 feet long, this sample section of suspension cable for the George Washington Bridge weighs an amazing 18.5 tons. The cable is made up of 26,474 individual steel wires, compacted under 400 tons of pressure. Before computers, this experimental section helped engineers model the effects of compression on the finished bridge's cables.
