Overview
Between Amesbury and Berwick Down in Wiltshire, Highways England is proposing to build a 1.8 mile (2.9 kilometre) tunnel to route the A303 under the Stonehenge World Heritage Site (WHS).
The RSPB objected to the scheme as published because the proposals would directly impact a number of stone-curlew nesting territories, and have potentially adverse effects on the Salisbury Plain stone-curlew population that exists on, between and around Salisbury Plain and Porton Down (known in ecological terms as the meta-population). Through continued work with Highways England, we are satisfied that sufficient measures are now in place to address our concerns. The scheme has now been approved, and we will continue to work with HE to ensure that the proposed measures are implemented.
