It was learned on July 3, 2020 that the Guangzhou Nansha-Zhongshan Expressway officially started construction. According to reports, the Nanzhong Expressway has a total length of 32.4 kilometers and is scheduled to be built in parallel with the Shenzhen-China Passage in 2024 to achieve seamless connection. The project is located in the core area of the Guangdong-Hong Kong-Macao Greater Bay Area. A bridge connects Guangzhou, Shenzhen and Zhongshan. After completion, it will further strengthen the role of Guangzhou in radiating the surrounding cities and enhance the status of the central city of Guangzhou Guangdong-Hong Kong-Macao Greater Bay Area. Promote the interconnection of the Guangdong-Hong Kong-Macao Greater Bay Area.

The main line of Nanzhong Expressway starts from Xinken Interchange and ends at Xinlong Interchange, connecting with Jiangzhong Expressway and intersecting with Guangao Expressway. The Wanqingsha branch line starts from Xinken and communicates with each other, passes through Nansha Wetland and Lingding Ocean, and connects the deep and middle channel through Wanqingsha.

According to reports, the entire line of the project is a bridge project, the technology is complex, the small and medium-span bridges are large in scale, and have high requirements for durability and quality. The thick mud and poor geological construction conditions along the line have brought great advantages to the full life design of the substructure. challenge. At the same time, the projects are densely interconnected and complex in design, with many functional requirements. To this end, the project team of Nanzhong Expressway will combine the location characteristics of the project to carry out research on multi-lane multi-lane junction and traffic function, research on construction technology of long-span cable-stayed bridges, design optimization of ordinary bridges, etc.

Nansha, located in the geographical and geometric center of the Guangdong-Hong Kong-Macao Greater Bay Area, is an important link connecting the urban agglomerations on both sides of the Greater Bay Area. Constructing a comprehensive regional transportation hub in Nansha can more easily realize the interconnection of the cities in the Greater Bay Area and shorten the city’s The space-time distance between them reduces the connection cost between cities, realizes the rapid flow of various element resources among cities, and makes all kinds of resources rationally arranged in the most efficient way.
