Hi all,
Is it ever correct for two roads to cross physically, at the same level,
but not create a junction between them?
The situation I have looks like:

With apologies for ASCII art. Cars go from A
In your special case I guess it would be OK to not create a junction.
That will however lead to (false) warnings in OSM data validators and
there is a chance that someone else will insert that junction later
on, so I'll recommend putting the junction there now and use
restriction relations. (e.g.

Yes there should be a node at the crossing.
Most of those ways are one way , so routing

Ok, I've done that. About time I learnt how to create relations :)
Anyone want to check

Be careful. The question about the junction node is NOT about routing
but about physical modeling. Even if both roads are not allowing
turning left or right, you have to add a junction node (and the
relations about turning restrictions), othewise we
Thanks Pieren, that's the kind of answer I was looking for: NO it's never a
good idea to have two highways cross at the same level without an explicit
junction.

On foot you can definitely and legally turn left or right.
So its a valid junction for pedestrian routing.
Ah yes, that's a very valid point.
