+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.
