The Arlberg Road Tunnel with a length of 13,976 metres is Austria's longest road tunnel. It carries the S16 Arlbergschnellstraße (German for "Arlberg Highway") under the Arlberg massif from Tyrol to Vorarlberg.
The tunnel is 1228 m (4,030 feet) above sea level with the road above the tunnel being 1640 m (5,400 feet) elevation.[1]
It was built between July 1974 and December 1978 and its costs amounted to 4 billion Austrian schillings (~300 million €). The tunnel is designed for 1800 vehicles per hour and equipped with 4 ventilation centres (one shaft with a height of 736 metres is the deepest in Europe), 12 vents, 43 cameras for traffic monitoring and 16 niches. In 1998 the tunnel was used by 2.6 million vehicles, where 18 % are accounting for freight transport. The Arlberg Tunnel is a Toll Road: Euro 8,50[2] (november 2010)
