- What we know of the WHS today can be considered, in part, as probably a ritualistic designed landscape.
- Many of the deliberately constructed elements might have been intended to be inter-visible to emphasise, and use, the topography.
- Neolithic long barrows in the western part of the WHS are grouped around the head of a dry valley in which the enigmatic Wilsford Shaft which appears to have been used well into the Bronze Age and later.
- Bronze Age barrows are set on ridges and slopes, respecting earlier monuments.
- The damage to the archaeological landscape caused by the road scheme would be permanent and irreversible.
- The road will cut through an unusually high density of prehistoric artefacts. Only a limited amount will be recovered and recorded.
- The whole of the A303 corridor is important to our understanding of the communities that built Stonehenge, especially at each end.
- The gash at the western end goes through an area of ancient field systems and linear ditches dating at least to the Middle Bronze Age. It is considered significant that areas favourable to cultivation remained uncultivated around Stonehenge itself in the Bronze Age.
- At the eastern end, Blick Mead, an area within chalkland spring that has been the subject of new scientific studies by the universities of Southampton, Buckingham, Tromsø, and Salzburg. The ground breaking findings suggest the potential survival of ancient DNA pollen and other ecology. Research archaeologists hope to find evidence that could recreate the landscape at the time.
- The survival of the environmental evidence has been thanks to the waterlogged conditions at Blick Mead. Archaeologists are concerned that the construction of the tunnel portal and associated flyover nearby might affect those groundwater conditions and detrimentally impact the survival of Mesolithic organic remains.
- Although Stonehenge WHS is world famous for Neolithic and Bronze Age archaeology, the latest research at Blick Mead highlights the unique importance of Mesolithic archaeology to understand life before Stonehenge.
