(sorry, didn't send this to the list at first)

Seehttp://wiki.openstreetmap.org/wiki/Key:height
"Physical attribute of other keys. Height is the measurement of vertical
distance. It indicates how "tall" something is."

So for bridges, it would be the distance from the ground to the_top_  of
bridge. And with some designs of bridges (eg a suspension bridge), this
may be significantly more than how high a vehicle you can fit under it
(maxheight).
