Stonehenge tunnel will square the circle | Letter

Criticism of the A303 tunnel beneath the Stonehenge world heritage site is rejected by Kate Mavor, Hilary McGrady and Duncan Wilson of English Heritage, the National Trust, and Historic England

The Council for British Archaeology is quite right that Stonehenge is much more than the ancient, iconic stones (Letters, 24 November). The current road severs this world heritage site and hampers access to hundreds of other prehistoric monuments across the site. That is why we want to see the road placed in a deep tunnel, well below the level of any archaeology.

The long-term benefits to the public, history and wildlife will be significant - reuniting this remarkable landscape, reducing the sight and sound of traffic, and allowing people to better explore and understand the site. The archaeology where the new road will emerge at either end of the tunnel has been thoroughly evaluated and the tunnel entrances carefully positioned. Archaeological finds will be handled sensitively and the results published and shared with the public.
