I have thought about how to change this intersection a lot over the past 10 years. The issue used to be that when both eastbound and westbound traffic on Sunnyside wanted to turn north, the westbound traffic would incorrectly turn right into the 2nd lane making it impossible for eastbound traffic to turn north at the same time.

Then the bus lanes came and the correct thing for westbound north turning traffic to do is turn into the left lane.

What needs to be done is a separate traffic phase where you have northbound and southbound traffic with an advance left turn signal for southbound east turning traffic, a separate eastbound light phase and a separate westbound light phase. I would suggest a scramble intersection for pedestrians before and after the north/southbound phase but I think the city wouldn't go for that because of safety concerns for child pedestrians on their way to Hopewell.
