Suzhou will build a bridge with the largest span in the world. How long is it? When will it be finished?

As a strong economic province in China, Jiangsu Province has super-strong cities such as Nanjing, Suzhou and Wuxi. Suzhou and the provincial capital Nanjing, in particular, were also defeated. Suzhou ranks in the list of new first-tier cities in China all the year round, and its economic strength is getting stronger and stronger. At the same time, Suzhou is also a tourist city, and Suzhou gardens rank first in the world. Since ancient times, many literati have come here and left many beautiful poems.

The development of Suzhou is inseparable from the construction of traffic lines. If you want to be rich, you must build roads first. Now the railways, highways and subways in Suzhou are gradually improving. As we all know, Suzhou is located in the middle of the Yangtze River Delta and is connected with the Yangtze River. Therefore, in order to meet the needs of traffic construction, Suzhou is also actively building its own bridges, such as Sutong Bridge and Shanghai Sutong Bridge. Now it is planning to build the Zhang Hao River Crossing Passage, the largest bridge in the world.

Zhang Hao River Crossing Channel connects Zhangjiagang City and Rugao City, which is about 28km downstream of Jiangyin Yangtze River Bridge, 57km upstream of Sutong Bridge and 16km away from Husutong Bridge. The whole line is about 28km long, with 8 lanes across the river and 6 lanes in the connecting section. The design speed is 100km/h, and the design speed is120 km/h. The technical standard of expressway is adopted.

It is planned to use the twin-tower suspension bridge with a main span of 2300 meters to cross the main channel of the Yangtze River, pass through Mazhou Island in Jingjiang City, enter the north branch, and then cross the Yangtze River channel through the twin-tower suspension bridge with a main span of 1.208 meters to reach Changjiang Town in Darugao City. The Yangtze River main channel bridge will become the longest span bridge project in the world after its completion.

Zhang Hao River Crossing Passage is expected to start construction in February 20021and June 65438+,with a total construction period of about 5 years. It is expected to be completed and opened to traffic in 2026. The total investment of this project is about 25.45 billion yuan. The construction of this project is difficult. So far, there is no bridge with such a large span in the world, and there is no technology to refer to, so it takes a long time to design and break through the difficulties.

The construction of Zhanghao cross-river channel has promoted the development of the region, promoted the development of tourism along the route, improved the traffic situation in Suzhou and eased the traffic pressure. This passage will bring more convenient traffic and economic links between Jiangnan and Jiangbei, promote the development of the Yangtze River Delta and provide space for Suzhou to enhance its own strength. The construction of this passage has attracted worldwide attention, so are you looking forward to its construction?
