Zhangjiagang - Jingjiang - Rugao Yangtze River Bridge, the world's largest span suspension bridge, is a key river-crossing channel to be constructed during the "14th Five-Year Plan" period. A few days ago, the last pile foundation of the north main tower of the north channel bridge of the bridge was successfully poured, announcing the completion of the construction of 46 pile foundations 4 months ahead of schedule.

According to the current monitoring, the maximum perpendicularity of 46 pile foundations is 3.5 ‰, and the design requirement is 6.7 ‰, all of which meet the requirements, laying a solid foundation for the next step of pile cap construction.
On March 10, the last steel shell was lifted and accurately positioned at the construction site of the anchorage caisson of the A5 section of the Zhangjiagang - Jingjiang - Rugao Yangtze River Bridge, marking the successful completion of the steel shell assembly of the largest caisson of the domestic highway bridge.
The steel shell of the caisson is composed of 36 well holes and 79 steel shell sections, with a total area of 5308 square meters, equivalent to the size of 13 basketball courts.

After the efforts of the first two months, on March 1, the pilot cable of Longtan Yangtze River Bridge crossed the river, and the construction of the catwalk of the bridge superstructure was officially started
On March 10, the erection of 338 main cable strands of the whole bridge of Nanjing Xianxin Road Yangtze River Bridge was completed, 11 days ahead of the original plan.At present, Jiangsu is steadily promoting the construction of nine cross-Yangtze River channels.
Jiangsu is also accelerating the construction of railway projects. Connecting the coastal port areas of Yangkou, Tongzhou Bay, Dongzao and Lusi to make it an important part of the collection and distribution system of the new port of Tongzhou Bay, the Yangkou-Lusi Railway is to be completed and opened to traffic in September.
Wu Wenjun, EPC project leader of Yang-Lu Railway Section 1 of China Railway Shanghai Design Institute
Yangkou-Lusi Railway is the first local railway with a 10 billion yuan of investment in Jiangsu. We focus on the construction period goal, improve the management efficiency, and strictly control the safety and quality, and simultaneously promote the construction of the branch line from Lusi Station to Lusi Port Station, so as to make contributions to the early opening of the "last kilometer" of the railway into the port and the high-quality construction of the new port in Jiangsu.
