Progress of Kunshan Central Expressway Project

After the pile tests of the south line, the west line and the north line were completed one after another, the S- 1 High-tech Zone Interchange of the South Line of Central, which was built by Shanghai Construction Engineering Group, took the lead in fully opening. As of press time, 52 bored piles for bridges have been completed at the high-tech zone interchange. It is reported that there are 2 1 12 piles in the high-tech zone interchange, of which nearly 500 piles are not affected by pipelines and traffic, and will take the lead in construction. It is expected that in early September, the G3 12 and Jiangpu sections where the high-tech zone interchange is located will be fenced and the vehicles will be handed over to the newly-built service road. By then, traffic control will be implemented on some sections.

According to Tang Wu, project manager of S- 1 Bid Section of Zhongnan Line, S- 1 Bid Section of Zhongnan Line includes bridge works such as main line elevated 2.472KM, high-tech zone interchange, Jinsong Road rhombic interchange, Dongyoujing Middle Bridge and Central River Bridge, as well as corresponding road works, drainage works and ancillary works. Among them, the high-tech zone interchange is located at the intersection of Jiangpu Road and G3 12, with Jiangpu Road in the north-south direction and G3 12 in the east-west direction. Jiangpu Road and G3 12 are both important parts of Kunshan Central Expressway, and the node is in an important position, and the two expressways intersect, so it is designed as a hub interchange with alfalfa leaves and semi-directional ramps. One-way two-lane semi-directional ramps are arranged in the northeast quadrant and southwest quadrant with large traffic volume, and the other two quadrants adopt circular ramps, with a total length of about 5948 meters. It is reported that the total investment of S- 1 Bid Section of Zhongnan Line is about 654.38+0 billion yuan, of which the interchange fee in high-tech zone is about 300 million yuan.

The overall construction period of the high-tech zone interchange project is 30 months.
