The Knappe Tunnel (Norwegian: Knappetunnelen) is a four-lane, twin-tube motorway tunnel in the city-municipality of Bergen in Vestland county, Norway. The tunnel is part of and consists of the first and second stages of the four-lane motorway project called Ring Road West (Norwegian: Ringvei Vest). The southern part of the tunnel goes under the Nordåsstraumen, a small strait connecting the lake Nordåsvatnet and the Grimstadfjorden.
The tunnel was built in two stages. The first stage, from in to (with a branch heading east to ), started in August 2006 and was opened to the public on 10 September 2010. Stage two will run from Sandeide to the southern tip of the lake , where it will intersect with National Road 555. There are two extra exits/entrances to the tunnel (other than the two endpoints of the tunnel). There is a branch that heads east off the main path of the tunnel to connect to the village of Straume, and another branch that connects to the village of Sandeidet/Varden.
The first part of the tunnel is 2.6 kilometers (1.6 mi) long, and the second segment is 2.8 kilometres (1.7 mi) long. The second segment is scheduled for completion in 2015. In total, the entire tunnel will be about 5.4 kilometres (3.4 mi) long. The lowest point of the tunnel is under the Nordåsstraumen strait, reaching 29 metres (95 ft) below sea level.[1]
