Nope. We've been over this many times on the talk-us list, and there
have been enough examples of boundaries not actually following
highways, despite TIGER claiming they do, and highways being realigned
but the boundaries not following, that it's become clear that
boundaries and highways should not be joined. That's not even getting
into cases where one or both is badly aligned, and they appear to
cross when they really don't (and thus joining at the crossing makes
that much more work for someone fixing one or both). I've even seen
this with railroads, where TIGER disagreed with reality, and a
mindless bot went and joined them at the supposed crossings.
