This week, the stretch of Adelaide Road where it intersects with Britomart Street/Herald Street, and then, a little further up the road, with Luxford Street.
As you can see on our hastily assembled little map on the right there, North-flowing traffic splits into two lanes once it gets past the Britomart/Herald intersection, so right-turning traffic gets its own turning lane into Luxford.
Now, this would work fine if there weren’t a couple of 5 minute parking spots (outside a dairy) in the straight-ahead lane (photo 2). Cars parked in that 5 minute spot (indicated by blue in the graphic) act as a roadblock, so once the turning lane hits a red light, traffic quickly backs up to the point where no-one can actually get into the straight-ahead lane (photo 3).
