Client: Jiangsu Provincial Transportation Engineering Construction Bureau

Location: Yangzhou City, Zhenjiang City

Area: 33 kilometers

Work Period: October 2016 - December 2017

Service to Scope: Survey and design

Located on the central axis of Jiangsu's expressway network, this project is a key segment of the province's "Vertical Route 4" within the "15 Radial, 6 Vertical, 10 Horizontal" expressway plan. Its completion will enhance the integrated transport system of the Yangtze River Delta, foster cross-river development, boost the Yangtze River City Group development, and support Jiangsu’s efforts to build a high-quality transport network and serve as a national exemplar.

     Project challenges span quality engineering, high-pier bridges, deep foundations, prefabrication, and smart highway systems. As a national and provincial demonstration project, it faces a tight schedule, complex deep-water construction (e.g., Mangdao River Grand Bridge), technical difficulties with high-pier segmental bridges, and extensive coordination with utility and highway networks.

     Leveraging our expertise, the team implemented quality engineering and introduced Jiangsu’s first fully prefabricated bridge structure with innovative anti-glare barriers. High-pier approach bridges used precast segments with external tendons, reducing weight by 20% and costs. The Mangdao River Bridge (19m head difference) employed steel pile cofferdams, completed in one dry season. As a pioneering "future highway", it deployed 5G coverage, fog guidance, vehicle-road coordination, and smart systems like danger monitoring and emergency bays.
