Chinese Engineers Build Underwater Tunnel Over 5,000 Meters Long, Astonishing the US Imagine driving a car. Not on a normal road. But right at the bottom of the ocean. Millions of tons of seawater are overhead, ready to crash down at any moment. And beneath your wheels is a concrete and steel structure assembled with near-perfect precision. Sounds like science fiction, right? But it's real. This is a tunnel across the sea. And today, we'll explore one of humanity's greatest engineering feats: the Shenzhen-Zhongshan Link. This tunnel is nearly 7 kilometers long. Wide enough for 8 lanes of traffic running side-by-side. And it was inaugurated in June 2024. Previously, traveling from Shenzhen to Zhongshan took two hours. Now it only takes thirty minutes. All thanks to this tunnel running through the seabed. So how did they do it? In this video, we'll go through four methods of constructing underwater tunnels. Each method has its own advantages, and the choice of which method depends entirely on the underwater terrain. Now, let's dive down.
