I agree with the take the center lane suggestion. You will slow some cars down, but its just for a brief moment. As soon as you get into the intersection, you have room to move right and allow cars to pass on your left since this one lane is going to two on the other side. If you ride the line between the right turn and center, you are pretty much inviting cars to try to squeeze by you on both sides.

EDIT: On second look, it doesn't look like it goes to two lanes on the other side (at least no for long). Either way, you can give impatient cars a chance to pass as you go through the intersection and then carefully merge back into traffic on the other side
