However, the design was met with much opposition; as many believed it to be an eyesore and felt that it would take away the natural beauty of the landscape. Eight years later, Strauss enlisted the help of engineers Othmar Ammann, Charles Derleth Jr., and Leon Moiuserff to redesign the bridge. By increasing the length of the suspension span to 4,000 feet, the engineers would be able to eliminate the need for a hybrid
