Golden Gate Bridge Paper

  1. 1. The Golden Gate Bridge Zach Himler Dr. Tom Marshall CSM 4660 1/14/13
  2. 2. The Golden Gate Bridge is a six lane bridge that connects San Francisco to Marin County accessible to vehicles, bicycles, and pedestrians. Before the bridge was built, the only way to cross over the San Francisco Bay over to Marin County from San Francisco was by ferry. Therefore, if you wanted to have a car to use on the other side, you had to drive all the way around the bay which would take several hours to do by car, so the ferries were a huge part of the financial economy of San Francisco. One day there was an eighteen hour traffic jam at the ferry docks waiting to cross over the bay. This is what made it obvious to the people of San Francisco that something had to be done to make it easier to cross the bay. The city of San Francisco called upon three engineers to help with their problem. They got in contact with Joseph Strauss, Irving Morrow, and Charles Ellis to have them come up with an idea. Their first idea was for two massive cantilevers with a central suspension segment in the middle to connect the two cantilevers. This idea would cost around $17 million, which was under what the city expected to spend on other ideas which were around $100 million. The city agreed to go with this idea only if Straus allowed input from several experts and alter the design. Southern Pacific owned the ferry services and objected to the Golden Gate Bridge being built since it would take away from their business, but the calling for a bridge was too large to not have one built. Construction on the Golden Gate Bridge started on January 5, 1933 and was finished in April of 1937. It is known as a Wonder of the Modern World according to the American Society of Civil Engineers. It is the 8th largest bridge in the world. The bridge is painted an International Orange and not black and yellow like the United States Navy wanted it to be so it can be seen through the fog.It is 1.7 miles in length, 746 feet tall in the towers, and has a minimum of 220 feet above the opening of where the San Francisco Bay meets into the Pacific Ocean. The south tower is 1100 feet out from land, and the north tower sits on the banks of the main land. The budget for the bridge was $27 million and was $1.3 million under budget when construction was finished. Some say the Golden Gate Bridge is the most beautiful bridge in the world but is definitely the most photographed bridge in the world. Until 1964, the bridge was the longest suspension bridge in the world at 4,200 feet but has since been beat in length. It is the second longest main span bridge in the United State just behind the Verrazano-Narrows Bridge in New York City. In 2005, there have been 1.8 billion cars that have travelled over the bridge since its opening on May 27, 1937.
