Hahntennjoch, High mountain pass between Imst and Pfafflar, Austria
The Hahntennjoch is a mountain pass at 1,894 meters (6,214 feet) that connects the upper Inn River valley with the Lechtal Valley through steep terrain. The L266 road winds through this rugged landscape and links several small villages together.
The road was built between 1948 and 1969, replacing an older mountain path. This ambitious project made it possible for the first time to have a safe and regular connection between the isolated valleys.
The villages along the route preserve their mountain way of life and offer visitors a window into how Alpine communities live. Local inns serve regional dishes that reflect the traditions of the area.
The pass is only open from May to October, as snow and ice make the road impassable in winter. Vehicles over 14 metric tons are not allowed, and the road demands careful driving because of its narrow sections.
The road features steep grades reaching up to 19 percent and includes a dramatic section with around 20 sharp hairpin turns carved directly into the rock. This technically demanding construction remains a testament to the engineering skill of the postwar era.
