Shanghai Yangtze River Bridge 1
On Friday evening, my mother drove me to visit my father, who works in Chongming Island, Shanghai. On the way, I asked my mother curiously, "before I went to my father's place, I had to take the train, the subway, and then the ship. Now why can I drive directly?" My mother looked at me with a smile and said, "you'll know later."
Two hours later, our car got off the highway, turned a corner and got on a bridge. At night, the lights on the bridge are bright, and cars come and go in an endless stream. The bridge is very long, winding like a dragon lying on the river. There are two thick pillars in the middle of the bridge. From a distance, it looks like the golden cudgel of the monkey king. Six big red characters are written on the cudgel - Shanghai Yangtze River Bridge. Twenty minutes later, we met dad.
After arriving, my mother touched my head and asked me, "now do you know why I can drive directly?" I nodded and answered loudly, "because of the Yangtze River Bridge in Shanghai."
After I went home, my mother taught me to search for information, and now I know: the Shanghai Yangtze River Bridge connects Chongming Island and Changxing Island, with a river crossing section of 10 kilometers and a total length of 16 kilometers. 5 km; shaped like "human", the straight bridge deck passes through the waist. Therefore, as the "first bridge of the Yangtze River gateway" in the future, the beautiful and atmospheric landscape will also be one of the characteristics of Shanghai Yangtze River Bridge.

The cross river section of Shanghai Yangtze River Bridge is 10 km long, with a total length of 16.5 km. The design scheme is a cable-stayed bridge with mature technology, which is designed as a two-way six lane bridge with a speed of 100 km / h. However, the shape of the main tower of the Yangtze River Bridge is different from the inverted Y-shape of Yangpu Bridge, the A-shape of Xupu Bridge, and the H-shape of Nanpu Bridge. Instead, the shape of the main tower is like "human", and the straight bridge deck passes through the waist. Therefore, as the "first bridge of Yangtze River gateway" in the future, the beautiful and atmospheric landscape will also be one of the characteristics of Shanghai Yangtze River Bridge.
The main span of the Yangtze River Bridge is more than 730 meters in the world, second only to the Yangtze River bridge connecting Shanghai and Changkong island. According to reports, this span can meet the two-way navigation requirements of 30000 ton container freighters and 50000 ton bulk freighters.
On November 28, 2007, the main tower of Shanghai Yangtze River Bridge was successfully capped. Shanghai Yangtze River Bridge is one of the main works of Shanghai Yangtze River Tunnel and bridge project. According to the current overall construction schedule, Shanghai Yangtze River Bridge will be completed in June 2008.
Three views on Shanghai Yangtze River Bridge
This month is busy. I went to the internal medical institutions under the jurisdiction of my department for year-end examination. The day before yesterday, the examination place was Changxing Island. There were outpatient department of Jiangnan Shipyard and Zhenhua Port Machinery health center on the island. They were all large enterprises. It's been nearly three weeks since the bridge was officially opened. Our car passed by the Yangtze River Bridge in Shanghai, and we also happened to visit the bridge. The bridge was built in a magnificent manner. It's very spectacular. It's really beautiful to have a panoramic view of the surging Yangtze River!
To be more practical, it should be said that it has completely changed the situation that people on Chongming Island can only travel by water. Now they can get out of the island even in windy and foggy days, so it is undoubtedly a great good thing for people living on the island. For enterprises, there are many benefits.
Regardless of the shortcomings of the United States and China, what was not considered in the design was that the four good lanes in front of the bridge in Chenjia town of Chongming suddenly merged into one section of one lane, and then there were four lanes. So many cars coming and going through this narrow lane, which was very congested. Chongming had no shortage of land. It was a big failure in the design.
When I got to Changxing Island, I checked my work and bought oranges at the roadside market. The soil of Changxing Island is suitable for growing oranges. Oranges are famous far and near. They are sweet and cheap. I bought 50 Jin and went back to the office to taste them.
