[1][2] The tunnel is part of the European route E134 highway, and this tunnel was built in 1968 to replace an older exposed road that was often impassable in the wintertime.
This section goes between the two mountains at Dyrskar and it is encased in concrete with a ventilation tower attached.
Dyrskar was a challenging place to pass when the road went there.
At Dyrskar, one can also see one of the oldest tunnels in Norway: the Old Dyrskartunnel which was in use from 1900–1919.
The old tunnel is located on the hillside west of the pass.
