One solution to your problem is break that segment into 2-one ways (seperate one way roads option on edit panel).

and then do not have connecting node or create restriction by mannualy selecting roads in sequence.

Hope it helps.
Please let us know if there is a better way to handle such scenarios?

I don't understand how this is a solution at all. You would HAVE to have a segment that connects the two split directions at intersections, in order to allow left turns onto cross streets. Manually adding turn restrictions here or omitting the connecting segments altogether isn't a solution at all, because it would also prevent turns onto cross streets. Please explain how this suggestion works, maybe I'm not understanding correctly.

Additionally, I don't think that road has enough (or any, really) of a median to necessitate splitting.

Sorry CBenson... I'm not really sure how u-turns work, to be honest.

Aha! What Alan said makes sense. I had never previously considered that "enable all turns" might do something different than enabling each turn manually.

It's a wide road, but I still would be hesitant to split it. All of the connections means it would be awfully complicated.
