I meant the Balmoral. When they repaved that stretch of road they did not paint the markings back on. There's still a few signs here and there advising people you can't drive there but overall I think the intention is that you *can* drive from North Bridge to South St David Street and vice versa.

U-turning at Waverley Bridge and South St David Street technically possible and I don't see any reason it should be illegal.

Have updated the map.
