height on the bridge instead of the way under it would IMHO indicate
the height of the bridge-construction (e.g. pilons, arcs), e.g. on
bridges like this:

maxheight on the bridge will restrict the height for who passes the
bridge on it, not under it. If you want to restrict the height for the
way that passes below, use maxheight for this way, not the bridge.
