Sansi LED: Sustainable LED Lighting and Integrated LED Display

The Shenzhen-Zhongshan Link will be located about 27 km downriver from the Humen Bridge, the only current bridge crossing of the estuary, and some 32 km north of the new Hong Kong–Zhuhai–Macau Bridge, which links the cities of Hong Kong, Zhuhai, and Macau at the southern end of the PRD. The grand construction started in May 2017 with an opening date in 2024.

The bridge connects two major cities on the Pearl River Delta (PRD) in China, the city of Shenzhen on the eastern side of the PRD, and the city of Zhongshan on the western side. It also consists of a series of bridges and tunnels, starting from Bao'an International Airport on the Shenzhen side.

The link is an integration of Bridges, Artificial Islands, Immersed Tunnels, and Underwater Roads, which is expected to reduce the travel time between Shenzhen and Zhongshan from two hours to just 25 minutes. The eastern section deploys an innovative construction technique featuring a steel-shell concrete immersed tube tunnel, which passes beneath the third main shipping channel in the area. At both ends of the tunnel, artificial islands have been completed. The western artificial island takes on a diamond shape, resembling a “ kite on the sea ”, while the eastern artificial island covers an area equivalent to that of 48 standard football fields. The project is strategically located south of Shenzhen Bao’an International Airport, and will serve as a vital hub connecting the tunnel with multiple land highways.
