(1)    Yes, you’re right: a bridge is a structure built to take traffic
(car, foot, railroad) over a river or road, exactly as a crane (the big
ones) is built to take containers form the dock onto the train or ship.

        It seems to me we would be on safer ground if we stick to common
understandings of what an object is, rather than worry too much about
specialized exceptions (Ponte Vecchio definitely). A bridge is a structure
built to take traffic (car, foot, railroad) over something. It's a concept
everyone gets.
        In the same way, a dam is a structure built to hold back water. It
could have a road going over it (Boulder Dam, Glen Canyon Dam), but it's
still basically a dam. And, again, everyone knows what it is.
        With Ponte Vecchio I'd be interested to see how you would indicate
the structures on the bridge. It's so much a part of the bridge's character,
but challenging to draw.

Ok.
And a dam is a waterway, according to the Map Features Wiki, so I suppose
that the same tag could be applied to a bridge crossing a river,
but what about the ones over railways and motorways ?
 
By the way,
i live in Firenze(Florence) so I suppose that if I draw and tag the Ponte
Vecchio (not a little bridge over a stream far away in the countryside 
) , 
a lot of people in the OSM-community will discover that  quite quickly
 :))

After all we can draw dams, that are a sort of “bridge” (pedestrians, cars

) on
the other !


Indeed. On of the best comments I heard when starting OSM was "If it's
physical, then you can map it"
I think deciding on how much detail you go into just depends on how much
time/patience you have.
