The history behind the filtered permeability in De Beauvoir Town – Hackney cyclist

I’ve written before about De Beauvoir Town, which is a very pleasant area of Hackney to live in, for lots of reasons, one of them being due to the extensive “Filtered Permeabilty” (roads which have been closed for through motor traffic but remain open to pedestrians and cyclists) which reduces motor traffic across much of the area to a very low level. This creates quieter conditions for residents, streets where children can play along with an added advantage, due to it’s location, of a direct & quiet East-West cycle route from Islington to Hackney via London Fields along with the so-called Cycle Superhighway 1 which is a not-as-direct-as-the-A10-but-quieter-than-it route from Shoreditch to Dalston.
Towards the end of the 1950’s the Victorian terraced houses on Buckingham Road and Tottenham roads were demolished and replaced by the Kingsgate Estate, opening in the early 1960’s. Shortly later hundreds of Victorian houses, pubs, shops and about half a dozen streets (almost all land between Downham Road and the canal, bar the industrial buildings surrounding the Kingsland Basin) were swept away to make way for The De Beauvoir Estate.
