I'm starting to like this idea. But the problem with this is how to
define "that section of way", so as not to introduce a maintenance
nightmare. My suggestion would be that the section of way should
correspond to the section that is indeed physically *under* the bridge
(on the order of 10m-20m long, usually).

Hmm, I suspect this may be tricky to edit, if you have two nodes
nearly on top of each other, near where the ways cross. Sounds messy
to me.
