This alley heads off Cross Street in Manchester and then ends after about twenty metres in the blank white wall of the building you see ahead. That building must have been built quite a while ago now, like in the 1970s at the latest. No car or other vehicle has come down this street in a long time. And as the double yellow lines imply, you aren’t supposed to even use this as a lay-by.
So why the arrow? Why a nice, bright, reasonably freshly painted ‘turn right’ sign (when Cross Street isn’t even one-way)? Answers on a postcard to Manchester City Council please.

Haha–wonder what fantastical thing might happen should someone attempt to make the turn, obstacle notwithstanding.
