Norway is embarking on one of the most ambitious infrastructure projects in modern engineering: the Rogfast tunnel, set to become the world’s deepest underwater road tunnel. The tunnel will descend around 1,300 feet (approximately 400 meters) beneath the seabed, cutting through solid rock below the North Sea. Once completed, it will stretch for 27 kilometers, making it not only the deepest but also the longest underwater road tunnel ever constructed. With an estimated cost of about 2 billion US

Norway is constructing the world’s deepest and longest underwater road tunnel, a $2-billion engineering mega-project that will let vehicles drive 1,300 feet below sea level. Once complete, it will transform coastal travel by cutting dangerous routes through fjords and mountains. • The Ryfylke and E39 tunnel systems are being built through solid rock beneath powerful Norwegian fjords. • Drivers will travel more than 27 kilometers underground, beating all previous underwater road tunnel records. •
