Sir - Keith Mitchell (Letters, March 14), leader of Oxfordshire County Council, criticises the rebuilt junction 10 of the M40 because it "creates huge queues".

He adds: "I am not sure whether this was a catastrophic miscalculation on the part of Highways Agency 'experts' or a deliberate attempt at traffic calming. What it is not is a helpful improvement."

This sounds remarkably like the pot calling the kettle black.

Through their ill-judged schemes, the traffic planning "experts" for Mr Mitchell's county council have created chaos at Frideswide Square and the roads around it; turned the Headington Roundabout into a confusing and dangerous "hamburger"; made a mess of Cowley Road by installing unnecessary chicanes; cluttered roads with unnecessary speed humps (and then wasted our council taxes by ripping out some of them); changed Abingdon's traffic layout for the worse; and generally made our streets more dangerous and more polluted than before.

Mr Mitchell is very good at giving himself a pat on the back, but perhaps he deserves a kick somewhat lower down?
