I put adjacent=yes on the highway=cycleway, so the user of the
cycleway=track tag on the main road can ignore ways with adjacent=yes
on them. The user who'd prefer to use highway=cycleway ways doesn't
know that the cycleway=track is a duplicate, but routers only have to
give a slight preference for highway=cycleway over cycleway=track to
use the "right" one (and even if they use the "wrong" one, it doesn't
much matter anyway).
