A360 temporary closure
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, will be carrying out work along the A360 to provide power. We will be installing high voltage cabling along this route.
To allow the work to be done as safely and as quickly as possible, a section of the A360 will be temporarily closed to the south of the A303 between Longbarrow roundabout and The Avenue roundabout between April and July this year.
During the closure, traffic will be diverted via the A345 and sections of the A303 and A36. Road signs will be in place to direct traffic to alternative routes.
Camp Hill and the Stoford to Woodford Middle road, which crosses the A360, will remain open throughout the works. Temporary weight restrictions will be in place on these roads.

Our progress
Work has begun on the A360 and the temporary closure will be in place until mid-July. Work will be carried out seven days a week and includes some overnight working so the work can be done as safely and as quickly as possible.
We will share up-to-date information about the project on this website - visit our FAQs page for more information. You can also sign up to receive email updates.
