The route opened on December 13, 2010[1] and shortens the travelling distance between Geoje Island and Busan by about 60 kilometers (37 mi).

[2] 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.

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.[4] 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).

[4] The route connects Busan, Korea's largest port city, to the shipbuilding industries and tourism destinations on Geoje Island.
