Busan–Geoje Bridge

The bridge was built under a public-private partnership. GK Fixed Link Corp, a consortium of seven Korean contractors, has a 40-year contract to build, operate and transfer the fixed link. The project is planned to cost US$1.8 billion. The government has provided only one-fourth of the cost; the rest is financed by the consortium to be repaid by tolls during the life of the contract. The lead contractor in the consortium is Daewoo Engineering & Construction, Co. Designers involved with the project include COWI A/S (Denmark), Halcrow Group (United Kingdom), Tunnel Engineering Consultants (Netherlands), Pihl and Son (Denmark), Arcadis US (USA), and Ben C. Gerwick (USA). ==Route==

The route connects Busan, Korea's largest port city, to the shipbuilding industries and tourism destinations on Geoje Island. The fixed link starts on Geoje Island, crosses three islets (Jeo, Jungjuk and Daejuk) and ends on Gaduk Island. In addition to the tunnel between Daejuk and Gaduk islands, a bridge is used to cross each of the islets. ==Bridge 1==

The bridge between Jungjuk and Jeo islands includes a cable-stayed bridge with a main span and side spans. This bridge provides of navigational clearance and has two diamond-shaped pylons. ==Bridge 2==

Between Geoje and Jeo islands, a bridge includes a three-pylon cable-stay bridge. This bridge has two mainspans of with side spans of . The pylons are tall and there is of clearance underneath the bridge. ==Tunnel==

When it opened, the tunnel became the world's deepest immersed roadway tunnel ( below mean water level) and the world's fifth-longest concrete immersed tunnel, at . It became the second-deepest immersed vehicle tunnel after completion of the Marmaray (Bosphorus rail tunnel) in 2013. The tunnel is made up of segments constructed in a dry dock in Anjeon. Each segment was towed by barges and sunk into place. == Toll ==
