Shenzhen-Zhongshan link is a core transportation hub project in the Guangdong-Hong Kong-Macao Greater Bay Area. It consists of one underwater tunnel, two bridges and two artificial islands, making it one of the most challenging cross-sea cluster projects in the world. The tunnel is part of a 24-km-long highway connecting Shenzhen and Zhongshan, situated on either side of the Pearl River Estuary.
