I've been trying to figure out how to tag some moderately complex exit
ramp systems when a single motorway_junction doesn't seem adequate. An
email to the newbies list led to an IRC discussion that led to a solution
that I like, so I wanted to present it here to see what other people think
and pos

As the original proposer of the destination_sign I think this is a
great example when the relation is useful. I assume there is some
roadsign before exit 91 that announces the upcoming exit. The
destination= of the relation would be what it says on the sign, which
could be a place or a road number.

That's a good point. Perhaps it would make more sense to have an exit_ref
tag (and document it on the wiki?).

What about similar to a turn_restriction relation? I.e. with
