A STEEL piling project to fence out the seawater and form the eastern artificial island at the mouth of the Pearl River for the construction of the Shenzhong (Shenzhen-Zhongshan) Corridor is making substantial progress.
Before the end of the year, the fencing project will be completed, and a diamond-shaped land mass, 930 meters in width and 1,136 meters in length, will be formed in 2020 to make way for the construction of interchange tunnels for vehicles between the elevated bridges and the underground tunnels, which are expected to be completed in 2022.
The east artificial island is located near the Shenzhen side, close to Fuyong Port and Shenzhen International Airport. The artificial island will serve as a junction where the underwater tunnel links with the ground roads and bridges to the Shenzhen airport and other city highways.
Compared with the western artificial island, work on the eastern island, equivalent to the size of 47 standard football pitches, faces many challenges due to its scale, number of intersections, level of environmental impact requirements and need to minimize disruption to the operation of the Shenzhen airport, the Guangzhou-Shenzhen Riverside Expressway and Fuyong Port.
The 24-km Shenzhen-Zhongshan Corridor, a key project for Guangdong, includes two artificial islands, two suspension bridges and the world's widest immersed tunnel with eight traffic lanes in two directions boasting a capacity for 90,000 cars per day.
After the corridor is completed in 2024, the trip to Zhongshan from Shenzhen will be cut to 30 minutes.
