Welcome

National Highways plans to improve the A303 past Stonehenge between Amesbury and Berwick Down by creating a new dual carriageway with a tunnel, removing traffic from much of this iconic setting.

The A303 Stonehenge project needs an electricity supply for construction and for the tunnel once built. Scottish and Southern Electricity Networks (SSEN), working on behalf of National Highways, has been carrying out work along the A360 to instal high-voltage cabling under the road between the Avenue roundabout and Longbarrow roundabout on the A303.

SSEN’s works on the A360 and the temporary closure have come to an end. The surface of the road has been reinstated and the road has been inspected and approved for reopening by Wiltshire Council.

We want to thank everyone who has been affected by the temporary closure for their patience and co-operation while the diversion was in place.
