Seven weeks of roadworks on the A420 and A34 at Botley interchange, in Oxford, begin on Monday, to install traffic lights on the four entry points of the roundabout.

A new pedestrian and cycle crossing will be created on the west exit of the roundabout towards Swindon.

The Highways Agency aims to minimise delays caused by the roadworks by carrying out work during off-peak lane closures between 10pm and 6am.
