hi, thanks for you answer

I do understand what you're saying, but given that those lanes don't look to be physically separated, I don't think they deserve to be separately mapped, I think that adding the proper turn restrictions would be the best we can do. The only physical separation between lanes I see is a 20 meters kerb just west of the crossing. 

Is it allowed to take a left turn from east allen to east spring?
