The long and expensive redesign of that junction increased the problems there. Which suited some who always wanted a more 'villagey' suburb. Unfortunately because of the local geography, parks, golf course, sports grounds, private playing fields The effects of that small closure had knock on effects that spread like ripples on a stormy lake, affecting many many more people than benefited. Simple solutions say calton using gilkes to exit onto Dulwich village thus simplifying the village junction, Allowing P4 to use court lane for faster transit nearer more people, Coaches and parents having drop off points with freshair walk to school, having actual bike lanes, banning on road parking etc etc
