Sir – Regarding the proposed expansion of Sainsbury’s premises at Heyford Hill (Report, November 5), if the city council is minded to approve this, I hope it will make it subject to an improvement in the layout as one exits on to the roundabout for instance with traffic lights and the company making a major contribution towards the costs involved. At present it is a hazardous experience leaving the premises, especially when there is heavy traffic such as at rush hour.
