Norway is building the world’s longest and deepest subsea tunnel
Norway is building the longest and deepest undersea road tunnel ever attempted, carving 27 kilometres through unstable rock nearly 400 metres beneath the Boknafjord. At those depths, water can burst through cracks in the mountain at pressures strong enough to blow into the tunnel walls, forcing engineers to battle one of the most hostile construction environments on Earth.
But Rogfast is about far more than a road tunnel. Hidden beneath Norway’s dramatic fjords, crews are building vast underground junctions, giant ventilation caverns and an entire subterranean world that could redefine what is possible in subsea engineering.
