In January 1933 a project to construct the worlds’ longest suspension bridge was started in San Francisco California as workers began excavating 3.25 million cubic feet of material for the structure’s anchorages. The bridge opened to automobile traffic on May 27, 1937. The first public crossing had taken place the day before during an opening ceremony, when 200,000 pedestrians walked over the new bridge.
