(the other) Martin's statement was that "there is no connection
between the street and the culvert besides the proximity", which is
not true in these cases. (Also, if you're splitting the road to put
the different surface tag there, why not apply the culvert tag to it?
There's no clear line between bridge and tunnel, and trying to define
one will result in failure.)
