How many roundabouts are there in Milton Keynes?
Ah, depends on what you call a roundabout. If you mean a fully formed structure with its own name and grass and flowers, then 300 is a generally agreed number. But if you mean anything which affects the gyratory movement of traffic (e.g. a painted bump in the middle of the road designed to control traffic within a housing estate) then figures as high as 1000 are bandied about.
