By the end of June this year, the Shenzhen-Zhongshan Link will be completed and ready for traffic.

As a major project of China's 13th Five-Year Plan, the Shenzhen-Zhongshan Link is the only direct highway connection between the two major urban clusters of "Shenzhen-Dongguan-Huizhou" and "Zhuhai-Zhongshan-Jiangmen" in the Pearl River Delta. It holds significant strategic importance for promoting connectivity across the Pearl River, enables efficient allocation of various resources, supports the development of the Guangdong-Hong Kong-Macao Greater Bay Area, and drives high-quality development in Guangdong.
