Miss has something to say:
Last week went to San Francisco for a walk, which was very shocking, and I can't forget it for a long time:

King's Golden Gate Bridge has always been popular among Hollywood blockbusters. The Hollywood movie [Venom] that was popular at the end of 2018 was filmed on the Golden Gate Bridge.
So, today I want to talk to you about how the Kinmen Bridge was built.
Golden Gate Bridge, called Golden Gate Bridge in English, is located above San Francisco Golden Gate Strait , California, USA. The north end connects Northern California and the south end connects San Francisco Peninsula. It is a landmark of San Francisco.
steel tower stands on the north and south sides of the bridge, 342 meters high, of which the height above the water is 227 meters, equivalent to a 70-storey building. The bridge between the steel towers has a span of 1,280 meters, making it one of the rare single-hole long span large suspension bridges among the bridges built in the world.
The height from the sea surface to the center of the bridge is about 60 meters, so even at high tide, large ships can still move unimpeded.
In a nutshell, the Kinmen Bridge is a miracle of the modern bridge project .
1933, the construction of the Golden Gate Bridge officially began. The bridge body is more than 1,900 meters long and lasted four years. It uses more than 100,000 tons of steel and costs US$35.5 million. It was designed by bridge engineer Joseph Strauss.
1933 Kinmen Bridge started construction in
bridge pier span length 1280.2 meters. When it was completed, it was the largest span in the world with suspension bridge , with a width of 27.5 meters, and a total of 6 driving lines in both directions. The bridge body is brown-red. The Kinmen Bridge has the fourth tallest bridge tower in the world, reaching 227.4 meters.
A unique design during the construction of the Golden Gate Bridge is that there is a safety net under the bridge. 11 people fell to death during construction, while 19 people were rescued due to safety nets.

In October 1935, the bridge tower was completed and workers were laying suspension cables.

The color of the bridge body of the Golden Gate Bridge is orange, because architect Alvin Morrow believes that this color is not only coordinated with the surrounding environment, but also makes the bridge more eye-catching in the heavy fog common in the Kinmen Strait.

The original concept of the Golden Gate Bridge came from bridge engineer Joseph Strauss. Strauss has designed more than 400 small inland bridges.

Strauss put a brick taken from his alma mater, the University of Cincinnati, Ohio, before pouring concrete on the South Pier.
1936, the bridge deck of the Kinmen Bridge was laid and a laminated cable was opened.

In May 1937, the news report vehicle passed the Golden Gate Bridge, which was basically built. The original design of the Golden Gate Bridge was cantilever truss and suspension structure, and then changed to see the three-span suspension bridge now.
Golden Gate Bridge is widely regarded as a model of beauty by the international bridge engineering community, and has also been rated as one of the modern world miracles by the American Association of Construction Engineers. It is also one of the most photogenic bridges in the world.
