Frafjord Tunnel
The 255th longest tunnel in the world
The Frafjord Tunnel (Frafjordtunnelen) is a road tunnel in Gjesdal Municipality in Rogaland county, Norway. The 3,812-metre (12, 507 ft) long tunnel is located along the Norwegian county road 281 connecting the villages of Frafjord and Gilja which are in two separate valleys with a large mountain between them. The tunnel opened on 10 June 1999 to replace the old, narrow, winding road that crosses the mountain pass above it, making the trip a faster and safer one.
