The Flekkerøytunnel is a single-tube, two-lane underwater tunnel in the urban area of Kristiansand in the province of Agder , Norway . It runs under the sound of Vestergapet, which separates the town's island Flekkerøya from the mainland, and the small island of Gammeløya and carries the provincial road 457 from Kroodden in the Vågsbygd district over to the island.
Construction began on August 1, 1988. The breakthrough took place on March 6, 1989, and the tunnel was opened to traffic on August 15, 1989. It replaced the ferry connection between Møvig in Kristiansand and Lindebøkilen on Flekkerøya. The construction cost was NOK 87 million , of which NOK 19 million was borne by the Norwegian Road Transport Authority and NOK 3 million by Kristiansand Municipality . The lion's share of NOK 65 million was raised through a toll that was collected until July 14, 1998.
