Busan-Geoje Fixed Link, Bridge-tunnel complex in Busan, South Korea
The Busan-Geoje Fixed Link is a bridge-tunnel complex spanning 1,870 meters that connects Busan city with Geoje Island across the water. The roadway uses advanced engineering techniques to withstand water pressure, earthquakes, and typhoons in this region.
The project was completed in 2010 and connected Busan with Geoje across water and below the seafloor. The work was realized through collaboration between engineers from several countries working together on this complex connection.
The fixed link represents South Korean engineering capabilities through its incorporation of advanced design elements to withstand regional environmental conditions and seismic activity.
Vehicles need about 40 minutes to cross this route, much faster than earlier ferry or roundabout connections. The tunnel and bridges remain open year-round and provide a direct path between the two locations.
The tunnel section descends 48 meters below sea level and ranks among the world's deepest underwater roadway tunnels. This undersea tunnel shows how engineers can build roadways at extreme underwater depths.
