The Sydney Harbour Bridge has been used for 100 years from "pregnancy" to "birth". After more than 40 years of brewing, in 1857, Sydney engineer Peter Henderson drew the first design drawing, and after repeated revisions, it was not until 1923 that the bidding was conducted according to the blueprint of Dr. Bradford, the chief engineer who supervised the railway bridge construction, and a British engineering company won the bid. 1924 Sydney harbour bridge broke ground and was opened to traffic on March19,0932, which lasted more than 8 years. Under the technical and economic conditions in the 1930s, aerial bridging was rare.

Golden Gate Bridge in San Francisco, USA (1933- 1937).

The Golden Gate Bridge in America is one of the world famous bridges. Built in 1933- 1937, it is known as the miracle of modern bridge engineering. About one million tourists come here every month. This bridge connects California and the San Francisco Peninsula. The whole bridge is magnificent and simple. The Golden Gate Bridge is famous for its dense fog. From the perspective of appreciation, the fog has a unique scenery. However, fog and winter rain are the biggest enemies of structural steel. The bridge is seriously corroded, and all 500 suspension cables have been updated in time-sharing sections. The painter must refresh the paint every day. The color of the Golden Gate Bridge is not really red, but an "international orange" mixed with red, yellow and black.

The Golden Gate Bridge is a landmark building with historical significance, which marks the glorious history that no longer exists. Many people think this is an unimaginable construction task.

Bridge on the river kwai, Thailand (1942- 1943)

Bridge on the river kwai, Thailand is located in Ganchafu, which is located at the northwest of Bangkok 122km. This bridge across the Gui River, the bridge over the Gui River, reflects a period of history during World War II: 1942, Japan invaded a large area of Southeast Asia. In order to attack Myanmar and India through Thailand and facilitate the transportation and supply of military operations, the Japanese army moved from 1944. The Japanese army forced hundreds of thousands of workers to work day and night with bayonets in order to complete the railway that would have taken six years to build in one year. Heavy labor and harsh conditions led to 6,543.8+0.6 million allied prisoners of war and 6,543.8+0.6 million civilians dying of hunger and disease, lying dead in the wilderness under the whip of the Japanese army.

The bridge over the Guangxi River used to be a wooden bridge, but it was destroyed after being bombed by planes several times. Only when the river is shallow can we see the residue. What we see now is an iron bridge built later, which is still open to traffic today.

35 Wuhan Yangtze River Bridge in Hubei (1956- 1957)

This bridge spans between Wuchang Snake Mountain and Hanyang Guishan, and is the first railway and highway bridge built by China on the Yangtze River. Total length of the whole bridge1670m, in which the main bridge1156m. 1955 started construction, and 1957 was completed and opened to traffic, which not only connected the three towns in Wuhan, but also opened the Beijing-Han and Guangdong-Han railways separated by the Yangtze River, forming a complete Beijing-Guangzhou line, which became the main artery connecting the north and south of China, and played an important role in promoting the economic development of the north and south.

In order to repair the bridge, Premier Zhou Enlai decided on the blueprint for the construction of the bridge, and instructed eight ministries and commissions to mobilize the most advanced equipment and the best experts in China to serve the construction of the Yangtze River Bridge. The Ministry of Railways also invited Xilin, a former Soviet bridge expert and academician of the Soviet Academy of Sciences, to form a 28-member expert group to provide technical guidance.

36 Nanjing Yangtze River Bridge (1960.1-1968.438+02)

Located on the Yangtze River in the northwest of Nanjing, connecting the urban area and Pukou District, it is a double-deck two-lane highway railway bridge, which was completed on February 29th. 1968. Its highway approach bridge is in the form of double-hole hyperbolic arch bridge with China characteristics.

The year when the Nanjing Yangtze River Bridge was completed was a national-level giant project, both economically and technically. When it was completed and opened to traffic, the whole country celebrated. At that time, pictures of this bridge could be seen everywhere, from families and units to public places. Many details of this bridge have left traces of that era: there are three red flags on the north-south bridgehead, symbolizing the people's commune, the Great Leap Forward and the general line of the 1950s. There is also a sculpture of workers, peasants, soldiers, Confucianism and businessmen in front of the bridge, which is over 10 meter high. There are reliefs such as "Long live the great unity of the people all over the world" around the bridgehead. From the completion of the bridge to the 1980s, it became one of the city symbols of Nanjing. Until today, the bridgehead of Nanjing Yangtze River Bridge is still a famous tourist attraction.

Perhaps because of its popularity, Nanjing Yangtze River Bridge was once the bridge with the highest suicide rate in China. It is said that no fewer than five people jump into the rolling Yangtze River from here every week. Coincidentally, its designer and Strauss, the designer of the Golden Gate Bridge, the bridge with the highest suicide rate in the United States, are college classmates.

37 Diego-coronado Bridge (1967.2- 1969.7)

This 3.4-kilometer-long bridge spans San Diego Bay, allowing people to easily enter the bathing beach in Corona and the naval base on the North Island from San Diego. It is characterized by a height of more than 60 meters and is specially designed for the passage of aircraft carriers, so any ship can pass freely. In order to avoid the steep slope, the bridge turned 90 degrees at sea. Seen from a distance, the bridge is very spectacular.

There is a white line in the middle of the bridge, with Asia in the east and Europe in the west. Six cars can run side by side on the bridge deck. If the bridge is full of cars, the west tower will tilt 86 cm inward and the east tower will tilt 90 cm. When there is a strong wind, the bridge will swing from side to side for one or two meters. But there is no danger.

39 Macau Aodang Bridge (1970- 1974)

1974 and 10 were completed in two months, with two lanes on the deck and sidewalks on both sides. It is a sea-crossing bridge connecting Macao Peninsula and Taipa Island. The lines are simple and generous, and the colors are bright, which is very harmonious with the architectural style on both sides of the strait. After nightfall, the bridge was brightly lit, like a string of beads, adding luster to the night sky of Haojiang. In different seasons, no matter day or night, the bridge is set off with beautiful figures, becoming a landscape of Macao and a symbol of Macao's development. 1In April, 1994, the Second Bridge (Friendship Bridge) was completed and opened to traffic, with a total length of 44 14m, which reduced the traffic load of the old bridge and played an important role in the prosperity of Macao.

No.40 Qiliqiao, Florida, USA (1972- 1982)

At one end of the bridge is Knight Island of Marathon, and at the other end is Duckling Island of the Low Islands, connecting the Gulf of Mexico and straits of florida. Although it is only 6.79 miles long, it is one of the longest bridges in the world. At the beginning of last century, there was an ancient seven-mile train bridge. After two hurricanes, 1935 and 1960, the old bridge was overwhelmed. At present, the new Qili Bridge built between 1972 and 1982 is a cross-sea expressway bridge.

When you drive past the new bridge, you can see the abandoned old bridge. Because its main part is still well preserved, many people regard it as a fishing trestle. This bridge is closed for several hours every April for a so-called "fund-raising run" to commemorate the reconstruction project of this bridge.
