Hi This is what I have:

description for mapping

There is no traffic signal, road marking or physical separation.

Moving from one way to another is always possible, except it has opposite direction.

Blue arrows are u-turns.

Green lines separate highways.

Orange ways are two-way streets.

My mapping is here. View in edit mode, maybe not rendered yet.

I think my mapping seems a bit confusing for the user.

UPDATE

Both valuable answers of @edvac and @chachafish seems better than what I mapped. Maybe the main problem of my map is that it doesn't fit the rule "One feature, one OSM element" for highways at the junction.
My mapping:

My Mapping

But I have two considerations here (Sorry for adding to question, but I think then it will make the question more general to benefit others, too).

In both mappings:

  1. The straight-forward path from top-right to bottom-left has a break in middle.
  2. The way that goes toward junction (from right side) created a very sharp angle with its right-hand-side highway , far outside the turn.

I'm not very proficient in mapping, but are these two issues acceptable in mapping?

Both mappings will work ok with routing machines.

As there isn't any roundabout at the main junction and cars are allowed to make u-turns, and there isn't either any road marking as you say, the proposed mapping (both mine and @chachafish) are acceptable, in my humble opinion.

This will work as well. The barrier is a kerb with trees.alt text

I would simplify the junction, eliminating this way and joining its two nodes in one, and also delete the two u-turn ways that connect both sides of the road for each of the green-separated roads.

One possibility would be like this:
