On the Queen's Quay loop light, its such a mess..........
Lets look at it:
What does it do?
1) It protects streetcar access to the loop by blocking cars
2) Its protects left-hand turn access from the west to a residential parking garage
3) It protects a second private road/drive access on the north side
4) Its protects access to the underground parking and drive circle for the Spadina Quay residence on the south side.
What an unholy configuration!
Very hard to fix this whole thing, it was very poorly thought out.
