The Busan–Geoje Fixed Link or Geoga Bridge ({{langx|ko|거가대교}}) is an 8.2-kilometer (5.1-mi) bridge-tunnel fixed link that connects the South Korean city of Busan to Geoje Island. The route opened on December 13, 2010{{cite web| last =| first =| authorlink =| title =South Korea's first bridge-undersea tunnel link opens| work =| website =| publisher =Deccan Herald| date =December 13, 2010| url =http://www.deccanherald.com/content/120599/south-koreas-first-bridge-undersea.html| doi =| accessdate =August 25, 2015}} and shortens the travelling distance between Geoje Island and Busan by about 60 kilometers (37 mi). The new road has two lanes in each direction and carries National Road 58.Yeoward 2010, p. 26.

The fixed link opens Geoje Island to tourist-related development and saves US$300 million in costs related to traffic delays from the longer route.Cho 2009, p. 25.

Design and construction

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.Cho 2009, p. 24.

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. It replaces either a 210-minute journey by road or a 120-minute journey by ferry. The new route cuts travel time down to 40 minutes.Halcrow project video (wmv), 1:04 minutes.

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 {{convert|1.87|km|mi|abbr=on}} bridge between Jungjuk and Jeo islands includes a cable-stayed bridge with a {{convert|475|m|ft|abbr=on}} main span and {{convert|220|m|ft|abbr=on}} side spans. This bridge provides {{convert|52|m|ft|sp=us}} of navigational clearance and has two {{convert|156|m|ft|abbr=on}} diamond-shaped pylons.Fraser 2008.

Bridge 2

Between Geoje and Jeo islands, a {{convert|1.65|km|mi|abbr=on}} bridge includes a three-pylon cable-stay bridge. This bridge has two mainspans of {{convert|230|m|ft|sp=us}} with side spans of {{convert|106|m|ft|sp=us}}. The pylons are {{convert|102|m|ft|sp=us}} tall and there is {{convert|36|m|ft|sp=us}} of clearance underneath the bridge.

Tunnel

When it opened, the tunnel became the world's deepest immersed roadway tunnel ({{convert|48|m|ft|sp=us}} below mean water level) and the world's second-longest concrete immersed tunnel, at {{convert|3.2|km|mi|sp=us}}. It is Korea's first immersed tunnel.Halcrow project video (wmv), 29 seconds. It became the second-deepest immersed vehicle tunnel after completion of the Marmaray (Bosphorus rail tunnel) in 2013.Rowson 2009.

The tunnel is made up of {{convert|180|m|ft|abbr=on}} segments constructed in a dry dock in Anjeon. Each segment was towed {{convert|35|km|mi|sp=us}} by barges and sunk into place.Cho 2009, p. 26.
