"The underwater highway of the Busan-Geoje Fixed Link is one of the deepest and longest immersion tunnels in the world, with a depth of 48 metres and a total length of 3.2 kilometres.

The Busan-Geoje Fixed Link opened for traffic in December 2010, reducing the travel time from Busan to Geoje from more than 2.5 hours to just 40 minutes."
