[OSM-talk] When is a bridge not a bridge?

In view of some changes that I've seen going through in my area 
recently, I'd be interested to know people's opinion on what constitutes 
a bridge. In particular to what extent are the approaches part of the 
bridge? I know I'm likely to hear wildly contradictory answers and 
there's probably no right answer.

       /                        \
      /                          \
____/                            \______

Are the ramps part of the bridge? If they are on solid embankments? If 
they are a lattice structure supported on pillars, perhaps like 
intermediate supports of the bridge itself? If they have parapets or 
not? Or do people feel the bit marked as bridge should strictly be only 
the span (or spans) itself?
