I can see that the Lewes Road improvement may have had in impact on Rottingdean, but what has happened to turn North Street from one of the worst in the EU and make Rottingdean High Street worse?
Interesting in July 2013 the Argus quoted North Street as being one of the worst in Europe and Rottingdean passed the pollution levels, whats changed. I don't think the level of through traffic in Rottingdean would have increased that much in 3 years...
