Brenner Base Tunnel

The Brenner Base Tunnel is a planned 55-kilometre-long railway tunnel through the base of the Eastern Alps beneath the Brenner Pass. It will run from near Innsbruck, in Austria, to Fortezza, in Italy, replacing part of the current Brenner railway. The line is part of Line 1, the Berlin to Palermo route, of Trans-European Transport Networks.

The Brenner Pass, in the Alps at the border between Austria and Italy, is one of the most important traffic connections between northern and southern Europe, and the motorway going over it is infamous for its frequent traffic jams. Pollution from this traffic is a major concern.The hope is to relieve this situation by greatly improving the railway connection between North Tyrol and South Tyrol with the new tunnel, which will allow trains to cross the Alps much faster.
