Tacoma Narrows Bridge (1940)
Efforts to save the bridge started after its collapse. They continued into May 1943.  It was decided that the bridge could not be repaired. The entire bridge would have to be taken down. A new bridge would have to be built. At the time, the United States was dealing with World War II. This meant the steel that would be needed to built the bridge was needed for the war. Steel from the old bridge cables and the suspension span was sold melted down. It cost the state more to destroy the bridge than it earned by selling the materials. The state lost over $350,000.
