|San Boldo Pass, Italy|
Why not just one, large tunnel? Is it that tunnel that connect italy to Germany? this is one road and it traverses up the mountain... umm how about ur on a hill..do tell how u can create one big one? maybe the montain fall down with a big hole inside. That is switch backs over the pass. I've been there! Way to rape the mountain side europeans. Amazing. if those are connected then they'd be fun to drift down. every entrance exits to a designated area, splits off so to speak, I've been there & it's a brilliant design. That's really neat. I like this pic its cool.
