Earlier, the main road over the mountains between Haugesund in Vestlandet and Østlandet (the capital of Oslo) went through the tunnel.

The current European route E134 pass through the newer Haukeli tunnel in a parallel corridor.

[1] The tunnel is about 60 metres long, for a large part hewn out of the rock, but with a natural stone arch in the south end.

It was built to improve conditions in winter due to heavy snow and high avalanche danger.

Perhaps the easiest, not the shortest, but the finest access is to park at the highest point on the road through Dyrskar.
