In cycle planning in the USA the "bikes only" direction on a road is
called a "contraflow" lane.
My goal in mapping includes that the routers work (both the car and bike
routers).
Thus I have sometimes mapped the contraflow as a separate short little
parallel bike path. It keeps the routers happy, even if it is not
always a perfect description of what's on the ground.
The other common USA concept is "Do not enter (except bikes, buses)".
That's a turn restriction, not a travel restriction.

Apart from that, it's inconsistent and confusing. All other values of
the cycleway key indicate that there is a physically separate lane or
track for bicycles, and that's what the cycleway key should really be
used for. cycleway=opposite is not a "cycleway", it's an exception from
an oneway restriction! The oneway:bicycle key is much better because it
fits in with other exceptions from oneway restrictions, such as oneway:bus.
So just use both for now. cyceway=opposite for backwards compatibility,
oneway:bicycle=no because it is the better tag.
