Using the Lion's Gate example, the outside lanes are only able to
display a red X on the contraflow direction, with only the center lane
changing directions (though the two "right" lanes when facing the
"fronts" of the signal gantries are able to display both colored arrows
and red X to indicate lane closures even though the outside lanes aren't
capable of reversing).  This is a single way that is never completely

A better example would be the George Massey Tunnel on 99, which omits
the oneway= tag completely on both motorways in the contraflow sections.
