When viewing the map with the AIV Flanders 2013-2015 aerial imagery 10cm background you can see a left turning lane that allows you to both turn left on Adrinkhovenlaan, but you should also be able to drive westward continuing on to Herentalsebaan.
You can use the GPS-trace here to see the path I was allowed to take.
