The Halsnøy Tunnel (Norwegian: Halsnøytunnelen) is a subsea road tunnel which connects the island of Halsnøy to the mainland in Hordaland county in Norway. The northern end of the tunnel is at Sunde, just south of Husnes, and the southern entrance to the tunnel is just north of the village of Sæbøvik on Halsnøy. The 4,120-metre (13,520 ft) long tunnel reaches a depth of 135 metres (443 ft) below mean sea level. Located on County Road 544, it opened on 8 March 2008 and is a toll road. The project included 2.2 kilometers (1.4 mi) of new road and cost 427 million Norwegian krone. Prior to the opening of this tunnel in 2008, the island of Halsnøy was the most populous island in Norway with no road connection. As an energy conservation measure, the tunnel is not fully illuminated at night, but rather when a vehicle approaches the tunnel, sensors turn on the lights, and then when all vehicles have exited the tunnel, the lights turn off again.
