Sir: Mary Rich (letter, 12 April) is living in cloud-cuckoo land if she believes the Newbury by-pass will do anything for anyone. With inevitable satellite development along it, it will simply shift pollution from one residential site to another and, with huge increases in road traffic predicted, it will eventually rat-run its inevitable overflow back through central Newbury. The only answer to Newbury's problem - the rest of Britain's, too - is firm control on traffic volume. But who is going to enforce it?
