Explore Norway’s incredible Rogfast project, a 27 km twin-tube undersea road tunnel designed to run nearly 392 meters below sea level. This mega engineering documentary reveals why the hardest part is not simply blasting through rock, but keeping water out, air moving, fires controlled, traffic safe, and emergency systems ready deep beneath the ocean. From probe drilling, explosives, rock bolts, shotcrete, tunnel lining, drainage, ventilation shafts, asphalt paving, sensors, and rescue drills to the wider E39 plan replacing ferries along Norway’s fjords, this video shows how one of the world’s most ambitious tunnel projects is being built under extreme pressure.
