Two mayors of neighbouring Paris suburbs caused totally confusion when they both decided that a street should be made into a one way trouble was it was as shared street and yes they both declared the one way in a different direction.
Police has to step in and calm the situation on the D909 which goes one way in Levallois-Perret and the opposite direction in Clichy-la-Garenne and order has been made to make the the road two way but currently under appeal.
