The Shenzhong Tunnel connecting Shenzhen and Zhongshan in South China's Guangdong Province finished construction on Monday, capping off a five-year-construction period and marking a further milestone in the development of the region's overall connectivity.

According to China Media Group's report, the Shenzhong Tunnel is the world's longest and widest steel-shelled concrete undersea immersed tunnel with total length of 6.8 kilometers. It is also a vital section of the Shenzhen-Zhongshan Link.

The Shenzhen-Zhongshan Link is a super sea-crossing project integrating bridges, islands, tunnels, and underwater channels. The total length of the link is about 24 kilometers.

The Shenzhen-Zhongshan link is expected to open to traffic in 2024. It will cut the commuting time between the two cities from two hours to 30 minutes, according to the Xinhua News Agency.

Following completion, the link will enhance transportation in the Greater Bay Area, encompassing the special administrative regions of Hong Kong and Macao, and nine cities in Guangdong Province, such as the capital Guangzhou and economic hub, Shenzhen.

In April 2023, the Lingdingyang Bridge, the cross-sea bridge which forms part of the Shenzhen-Zhongshan Link, with total length of 17 kilometers, saw its final segment fully joined.
