Improving the A303 between Amesbury and Berwick Down – NAO report

Editor News

The Amesbury and Berwick Down project – which involves building a tunnel beneath the Stonehenge World Heritage Site – is at an early stage but there are risks and uncertainty around it being delivered on time and achieving the benefits government hopes it will bring, according to the latest report by the National Audit Office.

The project forms part of the A303 and A358 road corridor which links the South East and South West of England. The Department for Transport (the Department) aims to upgrade the entire A303/A358 to dual carriageway over the 14 years to 2029 through eight individual projects and allow mile a minute journey speeds along the corridor.

The NAO recommends that Highways England and the Department for Transport keep in view the open to traffic date of December 2026 to ensure it remains realistic. They should also engage effectively with other Government departments and stakeholders to ensure all the expected benefits of the project are delivered.
