Golden Gate Bridge
The nearly mile-wide Golden Gate Strait was proposed as early as 1872, but it was not until the early 1920s that public opinion in San Francisco began to favor such an undertaking. On January 5,1933 construction on the Golden Gate Bridge was being started. The workers had to excavate 3.25 million cubic feet of dirt for the structures massive anchorage. The Golden Gate Bridge officially opened on May 27, 1937.
The Golden Gate Bridge was built to move products and people in and out of San Francisco. The building of the two towers on either end of the bridge was a challenge on its own. One tower was built on dry ground, but the other had to have a support built over 1,000 feet out into the water. This was accomplished by putting concrete walls into the water that were deep enough to break the surface of the water.
The Golden Gate Bridge is a very large rectangle shape that is above a large bay. The two towers on each side of the bridge have lots of steel wire cables that are connecting the two towers together. The bridges color is called " International Orange." Some people say that the bridge looks the best at night because of all of the lights.
