Norway is constructing an underwater road tunnel that will stretch over 27 kilometers beneath its fjords. The tunnel aims to improve connectivity between remote regions while reducing travel time. This engineering marvel will combine modern safety features with eco-conscious construction.

The Seikan Tunnel connects Honshu and Hokkaido beneath the Tsugaru Strait, stretching 53.85 km with 23.3 km under the sea. It supports passenger and freight trains at speeds up to 260 km/h on holidays. The tunnel's construction eliminated ferry reliance, cuts travel time, enhances connectivity, and exemplifies Japan’s advanced civil engineering.
