it's Sunday - let's have some fun and make all the traffic go on the other side of the road for a laugh.

That's Rio- today they close the three lanes nearest the beaches for pedestrians only - and get the rest of the traffic to go the wrong way , and one way only , on the opposite side of the road! They even have two sets of traffic lights facing two ways- normal days and Sunday's!.
You might expect Carnage - but they make it work seamlessly- well done Brazil.
Apparently they also do it Mon- Friday 7-10am to deal with traffic!
Can't see newcastle council going for it - could you!
