Drivers advised to plans journeys during next stage of Stonehenge tunnel scheme

The next phase of investigation work for the £1.7 billion A303 Amesbury to Berwick Down road scheme near Stonehenge will take place from next week.

The project forms part of the A303 and A358 road corridor which links the South East and South West of England. A tunnel at least two miles long would be built underneath the World Heritage Site.

Surveys have been taking place around Stonehenge since July, and the work will move onto and around the A303 Countess roundabout from next week.

A night-time lane closure will be in place on the roundabout on week nights only, from 8pm to 6am, for three weeks of drainage and sewerage surveys starting on Monday 7 October.

Following these surveys, a further six weeks of ground investigation work will be taking place at Countess roundabout from the start of next month. This work will involve the drilling of boreholes and shallow trial pits and, with lane closures in place for safety reasons, drivers are advised to allow extra time for their journeys.

Highways England’s proposed upgrade of the A303 between Amesbury and Berwick Down aims to unlock congestion. They say they want to conserve and enhance the Outstanding Universal Value of the World Heritage Site, benefit the local and regional economy and tackle the rat-running issue for local communities. The scheme includes:

  • eight miles of free-flowing dual carriageway
  • a tunnel at least two miles long underneath the World Heritage Site, closely following the existing A303 route, but a further 50 metres away from the Stonehenge monument
  • a new bypass to the north of the village of Winterbourne Stoke
  • junctions with the A345 and A360 either side of the World Heritage Site
