SHENZHEN - The Shenzhen-Zhongshan Link, a mega cross-sea passage in South China that features two bridges, two artificial islands, and an underwater tunnel, opened to traffic at 3 pm on Sunday.

Spanning 24 km, the link drastically reduces travel time between the city of Zhongshan and the technology hub of Shenzhen, situated on opposite sides of the Pearl River Estuary in Guangdong province, cutting the duration of the trip from two hours to around 30 minutes.

In a congratulatory letter, President Xi Jinping said the Shenzhen-Zhongshan Link is another large-scale transportation project in the Guangdong-Hong Kong-Macao Greater Bay Area following the Hong Kong-Zhuhai-Macao Bridge.

All participants, through their hard work and unwavering determination, have successfully completed the project with high quality, Xi said. “This fully illustrates that Chinese modernization can only be achieved through solid work, as all great causes are accomplished through concrete actions.”

The new transport route boasts eight lanes designed for speeds of up to 100 km per hour

The GBA, encompassing Hong Kong, Macao, and nine cities in Guangdong, covers 56,000 square km. It achieved a total economic output of over 14 trillion yuan (around $1.96 trillion) in 2023.

China aims to develop the area into a world-class city cluster, a global technology and innovation center, and a livable business-friendly location.
