+1, I like building=bridge. Wikipedia says that a building is, "a structure used or intended for supporting or sheltering any use or continuous occupancy" In this case, it is supporting a road (and in case of Ponte Vecchio, it supports a footway and houses) But tunnel isn't a building, so maybe man_made=tunnel? I like this better than relations too. Janko Mihelić
