Kjernfjell tunnel
The 286th longest tunnel in the world
Kjernfjelltunnelen (English: Kjernfjell Tunnel, Lule Sami: Girnotunælla) is a road tunnel on Norwegian National Road 77 (Rv 77) between the village of Storjord in Saltdal Municipality in Nordland county and the national border with Sweden. The tunnel runs through the mountain Kjernfjellet in the Junkerdalen valley. The tunnel has a length of 3,248 metres (2.018 mi). The construction work began in September 2016, and the tunnel opened to traffic on 17 October 2019. The tunnel replaced an exposed stretch of road and a bottleneck along Rv77 connecting Saltdal Municipality (in Norway) and Arjeplog Municipality (in Sweden). The old section passed through a gorge in the lower part of the Junkerdalen valley. The road was narrow, steep, and winding, and large vehicles often got stuck. Detour roads are E12 (Umbukta) and E10 (Bjørnfjell).
