OK, building=bridge it shall be, for my case. I see that the highway
and stream beneath still have to be 'covered' to render properly, and
raising the building to layer>0 doesn't help. The change is made. I
wasn't the one who used 'tunnel' - I agree that it's not right.
'covered=yes' is close enough. If you look straight up from the road,
you will see building and not sky, so the way is indeed covered.

At this point, I'm not going to try to map the short footway that
exists under the building, which runs roughly on the centerline of the
span and in turn crosses the stream on a small bridge. Too much visual
clutter for too little value added.

The negative building levels are correct. The floor numbering attempts
to be continuous among the connected buildings, and the ones to the
east were built later without renumbering floors; their levels are
lettered A-G. E and F connect to floors 2 and 3 respectively. There's
no connection on the other levels. Level A is still far above the
ravine, and the footway has many steps. It's really intended only as a
fire escape, but I used to use it as a shortcut when my laboratory was
in one of the buildings on the riverfront.
