Instead of "building=bridge", you might choose "man_made=bridge_deck"
or simply "bridge=deck" ?

Btw, the idea is not new. Check this bridge I traced in march 2010:
http://www.openstreetmap.org/browse/way/53582123/history

I used the tags combination "highway=bridge" + "area=yes". Then it was
replaced by "bridge=yes" + "area=yes" and finally by
"building=bridge".
I guess the "building=*" tag is used for rendering purpose. Which is
not correct.
