A thing with 18 sides is almost a circle, right?
That document
teuchter found is very interesting, the one that has disappeared and only exists now as a cached google shadow thing.
It's interesting because of the first paragraph, called 'background', which very clearly says that this is a measure designed to encourage cycling by making local journeys more difficult by car etc.
It doesn't say anything at all about 'a meaningful town centre'.
That bit, seemingly the key intention inspiration behind the closures, has been excised totally form all subsequent publicity / information about the closures.
The doc goes on to say 'it is anticipated that the whole area bounded by Camberwell New Rd, Denmark rd , Coldharbour Lane and Brixton Road will see a reduction in motor traffic though some roads may see an increase in local access traffic'.
Which has also never been mentioned in any of the council's communications about the closures that I've ever seen.
Why? I'm really stumped as to why the council would choose to go ahead with a plan that was (it now seems) designed for one purpose but present it so differently, sticking to the repetition of that line about 'a meaningful town centre' and so on.
