Seems like a little over use of "tunnel" in my opinion, but I accept it as 
personal preference. And, it is a solution, where I don't necessarily have 
one at this point for all those cases.

As far as wide bridges are concerned, I would probably not tag two lanes 
under six lanes as a tunnel, but would just use bridge for the six, and 
maxheight:physical= on a highway segment for the two. But, now I'm getting 
a bit off subject.
