In response to Grinch, I believe the 27 Kilometre tunnel crosses the border of Sweden and Switzerland.
If its so safe,why the hell is it 100 metres underground ?????
Most likely because that way it just requires they drill through rock, instead of having to knock down houses, roads, infrastructure etc which would be far more expensive... and considering that it doesn't have any breaks in the 'pipeline' its probably the most convenient.
I reckon its pretty exciting
