[OSM-newbies] R: R: What is a "bridge" ?

[Charlotte Wolter]

         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.
