Driving through the Hochtor Tunnel in the Grossglockner Road
Hochtor Tunnel is a high mountain tunnel at an elevation of 2,504m (8,215ft) above the sea level, located on the boundary between Salzburg and Carinthia states, in Austria.
Set high in the Hohe Tauern mountain range, on the main chain of the Central Eastern Alps, the toll road through the tunnel is totally paved. It’s called Grossglockner High Alpine Road. This road leads under the summit of the pass through the tunnel.
The tunnel is 311m (340yds) long. It’s the highest point of the Grossglockner High Alpine Road. The tunnel was constructed between 1933 and 1935. The access to the tunnel is pretty steep. Starting at Pockhorn, the ascent is 17.4 km long. Over this distance, the elevation gain is 1.400 meters. The average percentage is 8 %.
It’s said to be the highest surfaced mountain pass road in the country. The road is usually open from the beginning of May to the end of October. Beside the standard opening times, access to the road can be limited due to the changing weather conditions at these high altitudes.
