How Engineers Built Norway’s Impossible Rail Tunnel Deep Beneath the Ocean (Full Process)

Beneath the fjords of western Norway, engineers are drilling toward a record — not a railway, but a road tunnel diving deeper below the ocean than any tunnel ever built. This is the story of Rogfast, the Rogaland Fixed Link: 26.7 kilometers of solid rock, reaching 392 meters below sea level beneath Boknafjorden. When complete, it will be the world's longest and deepest subsea road tunnel, replacing a ferry crossing between Stavanger and Bergen. In this documentary, we cover: – Why Norway's fjords made a normal highway impossible – The geology hidden beneath Boknafjorden – Why engineers chose drill-and-blast over a tunnel boring machine – The 2019 funding crisis that froze construction – The engineering of an underground roundabout 260 meters below the sea at Kvitsøy – Where the project stands now, and when it's expected to open (2033) Sources: Norwegian Public Roads Administration (Statens vegvesen), project contractor announcements (Skanska, Implenia, Stangeland), and public reporting on the Rogfast project. #Rogfast #Norway #Engineering #Megaproject #Tunnel #Infrastructure 🎬 IF YOU LIKED THIS, YOU'LL WANT TO SEE THESE TOO: ▶️ How China Is Building a $30B Port in the Ocean That Defies Every Limit.    • How China Builds Giant Ships at the World'...   ▶️ How Singapore Built a $20 Billion Mega-Port in the Middle of the Sea    • How Singapore Built a $20 Billion Mega-Por...   ▶️ Inside the Secret Rebuild of the White House.    • Top 15 White House Secrets | 15 Weird Fact...
