In year 2012, the 10.4-kilometre (6.5 mi) long Jondal Tunnel was built a short distance from this tunnel. Using these two tunnels and a ferry, the road distance between the E134 highway in the town of Odda and the city of Bergen is much shorter than before. Using this route to travel from Oslo to Bergen is shorter than taking the E16 highway, and this route is much less sensitive to snow storms in the winter (which is fairly long in the mountains) than by taking Norwegian National Road 7 (which is the shortest route between Oslo and Bergen).
