Agreed. And it's clear that both ways of thinking are probably valid.

Can you please explain exactly what you mean by "using a node to
indicate maxheight"? This seems to be different from the posts which
seemed to suggest tagging, e.g. sections of motorway between exits,
etc. Like I said, my main argument for tagging the bridge is that it's
unambiguous and easy to implement and maintain.

If you have a consistent scheme for tagging the ways which pass under
bridges, which is unambiguous and easy to implement and maintain,
please share and document on the wiki :)

Cheers,
