Sir – I am mystified by the letter of June 28 from Peter Headicar, of Oxford Civic Society Transport Group, supporting the proposal to convert the section of the Oxford bypass adjacent to Barton West into a ‘boulevard’.

The whole point of a bypass is to take through-traffic round built-up areas, for the benefit of both traffic and residents.

It is a complete nonsense to nullify this separation by transforming part of a bypass into a residential street and I cannot understand how any sensible person, let alone a specialist spokesman of the Civic Society, could think otherwise.

I write as a strong believer in a humane urban environment and a cyclist, not a motorist but it is just as such that I believe that bypasses are desirable and should not be transformed into something else.
