The World's Longest Immersed Tunnel | Fehmarnbelt Tunnel

Imagine crossing the Baltic Sea in just 7 minutes. The $11 billion Fehmarnbelt Tunnel is currently the most ambitious mega-project in Europe. Once completed, this 18-kilometer engineering marvel will permanently replace a slow ferry and bypass a massive 160-kilometer detour, connecting Germany and Denmark like never before. But how do you build the world's longest immersed tunnel directly on the seabed without boring into the earth? In this video, we dive deep underwater to look at the incredible engineering, the environmental impact, and how this high-speed shortcut is changing Europe's map forever.
