Which contractor contracted the Sutong Bridge?

Jiangsu's money.

Nantong and Suzhou also contributed a part.

But Changshu ** doesn't seem to have heard of the investment.

The total investment in the Sutong Bridge project is 100 million yuan.

The total length of the Sutong Yangtze River Highway Bridge is 8206 meters, and the total length of the North Bank Connection Project is 1 kilometer, and the total length of the North Bank Connection Project Route is 100 kilometers, and the South Bank is connected to the total length of the project route.

The bridge deck of Sutong Yangtze River Highway is a two-way six-lane highway standard, and the speed of the north and south lines of Sutong Yangtze River Highway is 120 kilometers per hour. However, the speed of the bridge is designed to be 100 kilometers per hour, and the height of the main bridge is 62 meters, and the width is 891 meters.

That is to say, the height of the Sutong Yangtze River Highway Bridge can meet the navigation needs of 50,000-ton container ships and 10,000-ton fleets. A total investment of about 100 million yuan, and the full load of vehicles designed for the whole process of the Sutong Yangtze River Highway Bridge is also different, for example, the car is over 20 levels, and the trailer is 120.

Legal analysis: The current progress project is carrying out engineering feasibility study, the line plan is basically stable, due to the complex hydrological conditions of the Yangtze River section and the wide river surface, whether it is a bridge scheme or a tunnel scheme, its single scale and technical complexity are the world's first. Bridge and tunnel comparison, the plan has been consulted by experts, that the bridge plan is basically feasible, but it is still necessary to do a deepening research plan, before the end of June to hold a bridge and tunnel plan selection meeting, the first half of next year to complete the work, and strive to start construction at the end of next year.

Legal basis: The second Sutong cross-river passage is included in the "Outline of the Yangtze River Delta Regional Integration Development Plan". The implementation of the project is of great significance to the implementation of the Yangtze River Delta integration and cross-river linkage strategy, and can also effectively alleviate the traffic pressure of the Sutong Bridge.

The recommended line is located in the middle of the Sutong Bridge and the Hutong Bridge, and the huge amount is about 20 kilometers. The project starts from the intersection of Tongfu Road and Xinghu Avenue in Nantong City in the north to the intersection with Zhenxing West Road in the south and crosses the Yangtze River by bridge (the recommended bridge scheme is the main span of 2350 meters suspension bridge), crosses the Changyinsha Ecological Agriculture Demonstration Zone in Zhangjiagang, and uses the old Miaofeng Highway to the south in the form of an elevated highway at the Gangfeng Highway, crosses the Xitang Highway of Zhangyang Highway, and crosses the T-shaped intersection of Changhe Expressway at the end point, with a full length of the route. The project is studied according to the expressway standard, and the construction cost is estimated to be 100 million yuan, and the total cost is 100 million yuan.
