Hello! Thanks for reaching out. Another editor and I were investigating the circular junction and the direction switching ways, we believed it was better to have the roads split than mapped as one. It appears there is a section that never changes direction and that is separated by a double yellow line the lanes that go back and forth. This was enough justification for us to split the ways. I had updated all of the lanes and turn restriction tags accordingly. Clearly, you do not agree with the changes I have made and that is ok, I was just making it consistent with the wiki and general editing standards. The way you have it mapped suggests that the entire way switches directions, which I believe is not the case (please correct me if I am wrong)  as there are always lanes in the eastward direction.  In addition, the circular junction in its current state doesn't function well, it's not continuous and it should also not have multiple roads on the same node. Let me know if you would like me to fix these again, it would be my pleasure.  Thanks and have a wonderful day!
