The Flekkerøy Tunnel (Norwegian: Flekkerøytunnelen) is a subsea road tunnel on the county road 457 in the municipality of Kristiansand in Norway. The tunnel runs under the strait between Kroodden on the mainland and the island of Flekkerøy. The tunnel is 2,321-meter (7,615 ft) long, it reaches 101 meters (331 ft) below sea level, and the maximum gradient is of 10%. Construction start of the Flekkerøy tunnel was at August 1, 1988. The breakthrough in the tunnel was on March 6, and the tunnel was opened on 15 August 1989. It replaced a ferry connection between Møvik in mainland Kristiansand and Lindebøkilen on the island of Flekkerøy.[1] The tunnel has a strict 70 km/h speed limit.

Construction costs were NOK 87 million. Tolls were collected from the opening until July 14, 1998.[2][3]

Fire safety in the tunnel is considered as good.[4]

Speed control

There are an automatic speed control camera in both directions in the tunnel.[5] After complains the first years of driving in too high speeds, the police intensified speed traps in the tunnel. In the first half of 2009, the police exacted more than NOK 3 million speeding fines (which corresponds to NOK 16 000 each day on average) in addition to 22 police reports and 30 driver's licenses confiscated. That was despite the fact that the cameras are not activated at all times.[6]
