Rather than having a road with bridge_name, tunnel_name, whatever_name
(a similar situation occurs if you have a number of individual roads
making up something named "western bypass" or so), I was hoping for an
approach that would somehow use relations.

For example, I could imagine creating a way for the bridge only, and
another way for the road that crosses it, and then a relation saying
"this road uses that bridge". This would give us the additional
advantage of being able to model multiple ways going over the same
bridge.

But this is just an idea and not yet properly thought out; renderers
would have to be adapted to draw this correctly. There are numerous
other possible ways of using relations in dealing with the situation.

Bye
Frederik
