+1, and I don't see why we shouldn't have it. They will be less
complicated for following mappers than routes are for instance.

-1, you could do it as well with a polygon, thus it might be more
difficult to evaluate. If something it on the bridge, you will see it
(given that all objects are on the right layer), the polygon might get
difficult for objects that are hung under/from the bridge and
therefore could be either that or on the ground.
