深中通道（深中大桥， Shenzhen-Zhongshan Link）一镜到底

Shenzhen-Zhongshan Link, a road corridor that spans the Pearl River Estuary, connecting Shenzhen and Zhongshan in Guangdong Province, China. The link comprises an underwater (beneath the Pearl River) tunnel and an overwater (across the Pearl River) highway bridge. The Shenzhong Link is part of the Shencen Expressway, the starting section of China's national expressway network, geographically parallel to the Humen Bridge and the Hong Kong-Zhuhai-Macao Bridge. It serves as the third major traffic link across the Pearl River Estuary within the Guangdong-Hong Kong-Macao Greater Bay Area.
