Sir – I note that Sainsbury’s intend to extend and improve their Heyford Hill store (Report, November 5). No doubt this will result in even more traffic trying to enter the traffic stream at Heyford Hill Roundabout from the store.

It is extremely hazardous and dangerous attempting to do that at present — it’s a real ‘taking your life in your hands’ situation — so I trust Sainsbury’s and the council will do something to reduce the extreme dangers and not wait for the inevitable fatality.
