text: There's currently a turn restriction that allows only turning right towards A2 coming from South on Dj223 to this intersection. 
  I'm not sure if I fully understood you but if one is allowed to also turn left here (to go to the roundaboug DN22C ) then the current turn restriction should be removed. It _does_ seem a bit odd that currently one is only allowed to turn righ which in turn takes only to A2 southbound and not D22C or A2 North-bound.
