It is a much shorter route than the Fern Pass or the Flexen Pass over the Arlberg. The road is winding and steep, with grades up to 18.9 percent and is closed to traffic over 14 metric tons. The road is generally closed from November to April.
The pass is prone to avalanches, falling rocks, and mudslides. In 2004, an automatic system was installed that closes the road in case of blockage.
The present road was built in the late 1960s and opened in 1969.
