Inside the $8.7BN Fehmarn Belt Tunnel: The World's Longest Underwater Connection

Описание: Beneath the Baltic Sea, Europe is assembling one of the most ambitious engineering marvels of the 21st century — the Fehmarnbelt Tunnel, an 18-kilometer underwater highway and rail line connecting Denmark to Germany. Built using immersed tube technology, this $8.7 billion mega-project is snapping together like underwater LEGO blocks.

In this documentary, we uncover:

How 89 massive tunnel segments are built, floated, sunk, and sealed beneath the sea

The political and environmental controversies surrounding construction

Why this tunnel could change Europe’s future — and set a blueprint for global infrastructure

⚠️ This isn’t just a tunnel. It’s a glimpse into how nations are learning to build smarter, faster, and bolder — even under the sea.
