Hi.
Do you really know the area to change the labeling? Have you done a current physical survey about the area? 
-
I had to reverse the changes. I know and was in the area recently and I can assure you that the left turn is made via the right shoulder, there is no left side turn lane.

These similar turning situations are repeated in several places in the area, so please check physically or in any case through Mapillary before changing labeling, as it costs to keep the map updated and with true data to reality. 
Greetings.
