Norway is constructing the world's longest and deepest underwater road tunnel, Rogfast, which will span 27 kilometers and reach depths of 392 meters. This €2.4 billion project aims to connect regions along the west coast, reducing travel time by approximately 40 minutes by eliminating ferry crossings. The tunnel will feature two separate lanes and an underground roundabout for access to Kvitsøy. Safety measures include evacuation passages every 250 meters and dynamic lighting to alleviate monotony. Construction began in 2018, was paused, and resumed in 2021, with completion expected by 2033. Rogfast will set multiple records upon completion.
