So the solution is "do whatever you want?" Hrmm...

A couple of potential problems with this: What if someone later adds a
way that intersects the way with the restriction? The restriction must
then be removed from the part of the way that is beyond the bridge -
but this user should not be expected to know that the restriction even
exists...

Also, for longer sections, it becomes less clear that the maxheight
restriction is in regard to the bridge (versus the law, power lines,
trees, buildings, or something else). For ways with multiple bridges
in close proximity, it may become unclear which bridge the restriction
applies to. etc etc...

It gets a bit sloppy...
