A sea route with the total length of 8.2km (3.7km undersea tunnel and 4.5km cable-stayed bridge) connecting Gadeokdo Island, Gangseo-gu, Busan and Geoje-si, Gyeongnam, and the undersea tunnel was constructed by connecting 18 closures which was the longest (180m) single closure in the world, recording the first construction in open sea in the world and the deepest depth (48m) of water in the world.
