Map showing key archaeological monuments, the tunnel, location of proposed Expressway and National Trust land. We wish to acknowledge the generous support by Amesbury Museum and Heritage trust for this schematic map which is based on Highways England proposal, 2018.

What are we saving and why?

The Government proposes to widen the A303 trunk road to the south west.  The 4-lane carriageway, tunnel, slip roads and trenches would cross the iconic Stonehenge World Heritage Site (WHS): a landscape that is considered “the most archaeologically significant land surface in Europe without parallel”.  The whole Stonehenge landscape has an outstanding universal value that is of immense significance for all people for all time, and this transcends any consideration of sorting out a 21st century part-time traffic jam.

The whole site, extending to beyond the horizons around the famous stones themselves, is c. 5.4 km across. All of it makes up a “huge ancient complex” that holds many secrets yet to be discovered. Yet the proposal is for a 2.9km (1.8 mile) tunnel (see map above).  It would result in at least 1.6 km of above-ground 21st-century road engineering within the WHS.

All archaeology in the construction zones would be destroyed and the A303 would become the largest ever human intervention in an area fashioned and revered by over a hundred generations of our ancestors. and cause irreparable damage to the WHS in breach of the UNESCO World Heritage Convention and ignores UNESCO’s firm advice in 2017.

Our response to Highways England’s options consultation for the A303 Stonehenge in 2017 can be read here.

Petition and wording

We set up a petition in 2014 when the scheme was announced as part of a £15bn road investment fund.  Since setting up the petition, we have learned more about the recently discovered Mesolithic site at Blick Mead. This has led us to consider that if Government insists on a tunnel under the WHS, it must be long enough to avoid the WHS and its setting altogether. This would be in line with planning policy and World Heritage Convention safeguards. We cannot change the wording of the petition but road widening without further damage to the WHS is clearly expressed in the petition and its justification.

No further damage should be done to the archaeological landscape of Stonehenge.
Future generations would be appalled at those who decided that road widening should be at the expense of England’s most iconic World Heritage Site.
If A303 widening at Stonehenge is felt to be essential it should be done by means of a deep bored tunnel at least 4.5km long. Anything shorter would cause irreparable damage to this landscape, in breach of the World Heritage Convention.


Our responses to several myths explain our position on road widening by Stonehenge WHS.
