The 100 billion railway project is approved, and the world's longest high -speed rail cross -sea bridge is coming

Recently, the long -tier Yangtze River Delta cross -sea channel, Tongsujia Ying Railway, has recently been officially approved by the National Development and Reform Commission. It is expected to start construction in 2022.

The Tongsujiayan Railway is located in Jiangsu Province and Zhejiang Province. It is a north -south railway. The line starts from Nantong West Station in Nantong City in the north. ), Passed Suzhou City and Jiaxing City across Hangzhou Bay into Ningbo City.

The long -term operation length of the Tongsu Jiajia Railway is 310.113 kilometers, of which the newly -built line is 300.638 kilometers, the design speed is 350 kilometers per hour, and the entire line is estimated to invest 108.09 billion yuan. Among them, the new line length of the Zhejiang section is 165.914 kilometers, and the cross -sea bridge is 29.162 kilometers long. The design of Tongsujiajiayi Railway is 350 kilometers per hour, and the construction period is expected to be 5 years. There are 10 stations including Nantong West, Zhangjiagang, Changshu West, Suzhou North, Suzhou South, Jiashan North, Jiaxing South, Haiyan, Cixi, and Zhuangqiao.

The Tongsujiayan Railway is an important part of the coastal railway passenger channel of the "Eight Eighth Eight Eight Eight Eight" main skeleton of the national high -speed railway network. artery. The Tongsu Jiajia Railway will fundamentally eliminate the shortcomings of the regional intercity transportation north -south vertical supply system, and achieve the rapid passenger transportation of north -south wings in the Yangtze River Delta. After the completion of the Tongsu Jiajia -Ningrian Railway, it will accelerate the improvement of the Yangtze River Delta rail transit network system, which will greatly shorten the time and space distance from Ningbo to Shanghai, Suzhou, Beijing and other places. It is expected to achieve the "1 hour transportation circle" from Ningbo to Suzhou and Shanghai. Arrive.

According to the EIA publication, the Hangzhou Bay Cross -sea Bridge, which is an important node of this high -speed rail, is located between the west side of the Haiyan County and Ningbo City on the west side of Haiyan County, Jiaxing City. In the Hangzhou Bay Sea, the north of the bridge is located in the west side of the sea pond on the west side of the south of the South Taitou of Haiyan County, Jiaxing City. The south is located in ten ponds in Cixi City, Ningbo City, with a total length of nearly 29.3 kilometers. The bridge is a special bridge for high -speed railway passenger transport. The double -line railway is arranged, with a design speed of 350 km/h. The design and use of the main structure of the bridge is 100 years, and the construction period is 48 months. After the completion, it will become the world's longest and highest construction standard high -speed railway cross -sea bridge, which is a milestone for the construction of the world railway bridge.

It should be noted that the Hangzhou Bay Cross -sea Bridge, which is built this time, is the Hangzhou Bay Cross -sea Bridge of the Tongsujiayi Railway. It is a high -speed railway cross -sea bridge. Earlier, my country has built a Hangzhou Bay cross -sea bridge with a Unicom highway. This is the Shenyang -Haikou Expressway (National Highway G15) Hangzhou Bay Cross -sea Bridge. Shenyang -Haikou Expressway (National Expressway G15) Hangzhou Bay Cross -sea Bridge, 36 kilometers in length, 100 kilometers per hour, two -way six lanes. Above it is one of the components of the Shenyang -Haikou Expressway (National Highway G15), and it is also an important part of the urban expressway in northeast of Zhejiang Province. It was once the longest cross -sea bridge in the world independently designed and built in China. The Hangzhou Bay Cross -sea Bridge was founded on June 8, 2003; the Heilong Project was completed on June 26, 2007, and it was opened throughout the board; it was opened to traffic on May 1, 2008.
