Bridge Research George Washington Bridge Othmar Ammann, the Swiss-born architect and engineer, proposed a bridge design in 1923 that ultimately was chosen among other designs. Ammann's design, , was an engineering masterpiece, with a 3,500-foot center span suspended between two 570' steel towers. The bridge would ultimately have the capacity and strength to add a railroad or a second roadway with an additional six lanes if necessary. Across the Hudson River wire ropes, nearly miles in length were put in place. They were to be raised to the top of each tower and support the catwalk scaffolds for cable construction. The flooring and bracing complete the scaffolds, making a continuous catwalk from shore to shore. The four main cables are composed of parallel wires carried back and forth across the river, each containing 61 strands of 434 individual wires. Each strand wraps around a strand shoe in the anchorage. Each shoe connects to an eyebar which penetrates into the anchorage and holds the strand in place.
