Flekkerøy Tunnel
The Flekkerøy Tunnel (Norwegian: Flekkerøytunnelen) is a subsea road tunnel on the county road 457 in the municipality of Kristiansand in Agder county, Norway. It is the southernmost subsea tunnel in Norway. The tunnel runs under the strait between Kroodden on the mainland and the island of Flekkerøya. The tunnel is 2,321-metre (7,615 ft) long, it reaches a depth of 101 metres (331 ft) below sea level, and the maximum gradient is 10%. Construction started on the Flekkerøy tunnel on 1 August 1988. The breakthrough in the tunnel was on 6 March 1989 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][2]

Speed control
The tunnel has a strict 70-kilometre-per-hour (43 mph) speed limit. There are an automatic speed control camera in both directions in the tunnel.[6] After complaints during the first few years after its opening of people driving too fast, the police intensified speed traps throughout the tunnel. In the first half of 2009, the police stopped many speeders, collecting more than 3 million kr in speeding fines (which corresponds to an average of about 16,000 kr each day). They also filed 22 police reports and 30 driver's licenses were confiscated. That was despite the fact that the cameras are not activated at all times.[7]
