If there's no junction, this won't happen.
Levels are, for the most part now, deprecated though we still use them. The basemap had junctions between overlapping roads which caused lots of turns off of bridges. Those are, for the most part, gone now in those basemapped areas. There was a map problem in the older editor which would suggest that, because these two roads overlap and are at the same level, that a junction may be needed. That code isn't active any longer. I do not believe that level serves any actual purpose any longer, but I'm not saying that officially.

I find that interesting and I've never see that situation. Depending on when this was, any not speaking with any authority to this exact situation, is that this happened, someone saw it on the edit map and removed the junctions between the roadways, but didn't change the levels. Another person posts a UR the next day, before the map update completes, and shows the same bad routing. To the second editor, it looks like the levels caused the problem, which, I believe, is not the case. It was only the junction.
