This is what I also do (without the little sidewalk loop) with heavy intersections like Winant/Sylvan Ave (Rt 46) to turn left onto Bergen Tpke. I just slow down and/or stop if needed before the intersection. Look for cars turning right behind me. Cross with the bike on the ped walkway to the other side. Stop and turn 90 degrees to face the way I want to go. But this doesn't really help in the OPs case. Its an unusual intersection with the two turn lanes on the right with the bike lane on the left (in the middle). In the OP's intersection, I would also just stay in the bike lane and stop as needed for cars and trucks breaking the law to cross into a lane on the left. I really haven't come across an intersection like the one above in my NJ/NYC area.
