Modelling Intersections

I’m using JOSM with the Lane and road attributes Map Paint Style to model an intersection.

I have the appropriate number of lanes for each incoming and outgoing link, I’d like to now connect the incoming lanes with the appropriate outgoing lanes. I’ve googled for hours and still can’t find any discussion of this, I know in OSM you’re able to have links connecting to others and splitting but I can’t figure out how to do it in JOSM.

This is my intersection, I want a way to connect all the lanes together properly but can’t figure out how.

Here is an intersection that I think as most of the same things you show (except the right turn ways).
