no, don't look at "online dictionaries" when talking about technical issues
that are well defined. IMHO the online dictionaries are inaccurate at this

Which does make sense. A tunnel going underground can be crossed mostly
without even noticing the tunnel while a street that is covered or inside a
tube at groundlevel will mostly be an uncrossable obstacle, so that the
impact of this difference is huge! The functionality might in some cases be
identical for who uses the tunnel / street, but it is not for the rest.
