Golden Gate Bridge in San Francisco City, California

Construction of the Golden Gate Bridge began in 1933 and was completed in May 1937. It took 4 years and more than 100,000 tons of steel at a cost of $35.5 million. The whole bridge is magnificent and unpretentious in shape. The bridge body is vermilion red, lying on the blue sea and white waves, and the lights are just beginning to shine, like a dragon volleying into the sky, making the night sky of San Francisco even more magnificent.

History

Construction of the bridge began on January 5, 1933, completed in April 1937, and opened to pedestrians on May 27 of the same year. Strauss placed a brick from his alma mater, the University of Cincinnati, Ohio, before pouring concrete on the South Pier. The next day, as President Roosevelt pressed a button in Washington, the bridge was officially opened for automobile use.

Voters in the San Francisco area issued an initial $35 million in engineering bonds, using their homes, farms and businesses as collateral. The last bond was paid off in 1977, with the $35 million in principal and $39 million in interest all coming from bridge toll revenue.

In 1869, the “Emperor” Norton I of the United States ordered the construction of a suspension bridge over the San Francisco Bay, and has since ordered the construction of the bridge several times. Unlike his other decrees, this decree was eventually not only pursued, but also attributed to him, but it was more than sixty years later. In 1933, San Francisco began to build a suspension bridge at the site planned by Norton I. In 1936, the One of the most famous bridges in the world, the Golden Gate Bridge, was built and one of its bridges was marked in memory of Norton I “Travelers, please stop and thank Norton I, Emperor of the United States and protector of Mexico (reigned 1859-1880) who had Foresight, conceived and ordered a bridge over the San Francisco Bay”.

The landmark Golden Gate Bridge in San Francisco, USA celebrated its 70th birthday on May 27, 2007. The Golden Gate Bridge Administrative District has released an official report, giving due credit to a lead engineer named Iris before the bridge was built. Until May 20, 2007, his name was not on the Golden Gate Bridge’s merit book. As the bridge’s chief engineer, Strauss has long been dubbed the father of the Golden Gate Bridge and is honored as one of the greatest engineers of the 20th century. There is a statue at the end of the Golden Gate Bridge, erected in his memory after his death in 1938.

However, the design of the Golden Gate Bridge and the thousands of important mathematical calculations required to build the bridge, the new book “Golden Gate Bridge: Chief Engineer’s Report 2” published on the 24th, was actually completed by an engineer named Iris. Iris was fired before construction on the Golden Gate Bridge began, and Strauss took all the credit. Iris returned to teaching at the university and died in 1949.

After 70 years, the hero who built the bridge has been belatedly affirmed. The mysterious legend does not affect the 100,000 commuters who cross the bridge between San Francisco and the northern peninsula every day. The image of the Golden Gate Bridge has become the best endorsement of San Francisco, and according to statistics, about one million tourists come here every month. There are currently 200 people “serving” the Golden Gate Bridge, including collecting tolls, repairing and painting steel cables.

The color of the Golden Gate Bridge is not true red, but “international orange” mixed with red, yellow and black. The painter must paint on the moving scaffolding, first use pressure cleaning, then apply three coats of paint, and another colleague ties On the spider web attached to the wire, do the work of the paint check. The Golden Gate Bridge has both aesthetics and problems. The Golden Gate Bridge is famous for its dense fog, but both fog and winter rain are the worst enemies of structural steel, and it is severely rusted. All five hundred suspension cables have been updated in time-sharing sections. In the past 70 years, the “wind” has locked the bridge three times because of too much wind.

Golden Gate Bridge

The Golden Gate Bridge was built in 1937 at a cost of 35.5 million US dollars. It is one of the largest single-hole suspension bridges in the world. The Golden Gate Bridge is 2,780 meters long, and the height from the sea to the center of the bridge is about 67.84 meters. There are two towers up to 227 meters at both ends of the bridge. The two ends of the orange bridge of the Golden Gate Bridge stand with steel columns, which are connected by thick steel cables. The middle of the steel cables sags, almost close to the bridge body. The entire Golden Gate Bridge looks unpretentious and majestic. To commemorate the designer and engineer Strauss, his bronze statue was placed beside the bridge.

On the day the Golden Gate Bridge was inaugurated, 200,000 people happily walked across the bridge to celebrate the day. Today the Golden Gate Bridge is one of the busiest bridges in the world, with about 100,000 cars rumbling across the bridge every day. The Golden Gate Bridge is one of the world’s famous bridges and is known as a miracle of modern bridge engineering. The designer of the Golden Gate Bridge was engineer Strauss, and his bronze statue was placed beside the bridge to commemorate his contribution to the United States. The bridge stands on the Golden Gate Strait, which is more than 1,900 meters wide in California, USA. The Golden Gate Strait is the entrance to the San Francisco Bay, with steep sides and deep water channels. It was discovered by the British explorer Francis Drake in 1579 and named by him.
