gzt: ?Some legs be quite long and it would be madness to apply this one way scheme to them without a free left and island system.
I can understand that this road is being treated as a 'dogleg' with the green sign at the first intersection. But from google streetview, it look more like two right angled interesections, and if you are approaching it from the other direction it is treated like two intersections, rather than a dogleg. If it barks like a dog and looks like a dog, I think it is a dog.
