two one way roads is the generally accepted method

http://wiki.openstreetmap.org/index.php/Key:highway

has lots of info on tagging roads

there's also a relations proposal being discussed to use on
dual-carriageway roads like this, to enable the opposite carriageways
to be "connected" in a meaningful way:

i think there's a relation for this; it came up a week or two back
