Stonehenge: Proposed Road Alterations

Debate between Andrew Murrison and Alex Burghart

Tuesday 5th June 2018 Westminster Hall

[Alex Burghart]

I thank my hon. Friend for his remarks and will turn in a moment to what we do not yet know about Stonehenge.

[Dr Andrew Murrison (South West Wiltshire) (Con)]

My hon. Friend should not be at all sorry that he does not come from Wiltshire. Those of us who do are very grateful to him for taking the interest that he has. Does he appreciate that the sensitivity of the matter is demonstrated by the fact that we are going to the extraordinary expense of constructing a tunnel past the stones, which will undermine, so to speak, archaeology that may be explored in the future? That cost should not be underestimated, as logic would dictate that we did a cut and cover, at the very most, or simply had a dual carriageway. Instead, we have gone for a tunnel, which will leave the great bulk of the archaeology that may as yet be undiscovered uninterrupted and undisturbed.

[Alex Burghart]

I thank my hon. Friend for that excellent point. There is no doubt that a tunnel under part of the site will protect that very part. Notwithstanding the concerns that have been raised about toxic gases that could be released by tunnelling through chalk—not something I am fit to comment on—I believe that part of the site will be preserved by digging deep down for a tunnel. However, regarding the tunnels, the widening of roads into dual carriageways and particularly the flyover on the eastern end of the site, I seek reassurance that at the very least we are doing everything in our power to ensure that we do not damage this precious environment and that, if we find we are doing so, we take other steps.

I wish to make three points in connection with the issues I have raised. The first is about the academic, archaeological response that has been made to the consultation, which it is only right to put on record. The second is the response of UNESCO and the International Council on Monuments and Sites to the proposals as they stand. The third is about the relationship we have with world heritage sites and how we might seek to develop that relationship in the future.

[Alex Burghart]

I am grateful to my hon. Friend for his comments. I am one of those people who have sat on the A303 on a hot summer’s day in stationary traffic with an agitated child in the back and a wife looking at me as though to say, “We should have taken a different route.” The last time I went on the A303 in summer, we were in stationary traffic for two hours because the President of the United States had decided he would visit Stonehenge that day. The security forces of the United Kingdom and the USA had bilaterally decided to stop everything going east and west without telling us what was going on. I fully acknowledge that there is a traffic problem on the A303 and that local residents have a right to ask for that problem to be solved. I am an Essex MP; I do not wish to go into alternative routes. I am seeking assurances from the Government that, whatever decision is made about where the road does or does not go, we have foremost in our minds a determination to preserve this completely unique environment.

First, I turn to the comments made by the group of 22 experts who have worked at Stonehenge over the past 10 years. They have raised particular concerns that the

“creation of new sections of dual carriageway and slip roads at each end of the tunnel, within the boundary of the WHS, would set a dangerous precedent by allowing large-scale destructive development within a WHS”.

I will turn to that point again in a moment. They also said:

“The construction of the portal at the west end…and new sections of road in its vicinity, would damage an area with an unusual and nationally important concentration of long barrows”

belonging to the millennium prior to Stonehenge. They said:

“The proposed new road would cut across the site of a settlement from the time of Stonehenge’s construction, perhaps where the builders of its Bronze-Age phase once lived…At the tunnel’s eastern end, construction of its portal may affect groundwater conditions which could harm nationally important Mesolithic remains at the site of Blick Mead.”

The 22 archaeologists are employed by UK universities. Many were employees of various universities or English Heritage when doing research at Stonehenge. Seven of them are members of the A303 Scientific Committee at Stonehenge. It is a very good thing, which was set up to ensure that the process gets good advice on limiting the damage of the current proposals. However, its remit does not extend to looking beyond that; those are the terms of engagement. Seven members of the scientific committee were sufficiently concerned to make their own submission to the consultation.

I do not know the best way of doing this, as I do not wish to read out all 22 names, but I hope they can be in some way included in the Official Report. [Interruption.] I am being told to read them into the record. They are: Professor Mike Parker Pearson, University College London; Dr Umberto Albarella, University of Sheffield; Dr Mike Allen, Allen Environmental Associates; Dr Barry Bishop, University of Buckingham; Professor Nick Branch, University of Reading; Dr Christopher Chippindale, University of Cambridge; Professor Oliver Craig, University of York; Dr David Field, formerly of English Heritage; Professor Charly French, University of Cambridge; Professor Vince Gaffney, University of Bradford; Paul Garwood, University of Birmingham; Professor David Jacques, University of Buckingham; Dr Nicholas James, University of Cambridge; Dr Joshua Pollard, University of Southampton; Professor Colin Richards, University of the Highlands and Islands; Dr David Robinson, University of Central Lancashire; Professor Peter Rowley-Conwy, University of Durham; Professor Clive Ruggles, University of Leicester; Dr Colin Shell, University of Cambridge; Professor Julian Thomas, University of Manchester; Professor Christopher Tilley, University College London; and Professor Kate Welham, University of Bournemouth.

They have concerns, and further concerns have been raised by a different body that worked on the Blick Mead archaeological site in the east. The principal concern there is about the water table, since the deoxygenated environment, as I have explained, is extremely helpful in preserving organic matter from a long time ago. They are concerned about two aspects of the proposed route: that the extension of dual carriageway could create additional weight on the road, squeezing water out of the site; and that the weight of the flyover could squeeze the soil down, again pushing water out.

Such concerns are understandable from a professional viewpoint, given that in 2000, an extraordinarily important Mesolithic site in North Yorkshire called Star Carr was damaged when drainage ditches—which, I believe, had been approved by heritage organisations—were cut through. That has caused irreparable damage to a truly remarkable site. For the record, the academic paper charting what happened at Star Carr can be found in Proceedings of the National Academy of Sciences of the United States of America, November 2017, “Lessons from Star Carr on the vulnerability of organic archaeological remains to environmental change”. Within a short period from the changes being made to the Star Carr environment, irreparable and irreversible damage was done to its archaeology.

I was pleased to see in chapter 11 of the Highways England preliminary environmental information report that the potential impacts of the construction of the scheme at the eastern end—over the Countess roundabout—were being looked at. Some opportunities to avoid or mitigate the impacts by influencing the design of the proposed scheme were noted. However, from the information given in that document, it is very difficult to see exactly how Highways England has reached its conclusions. There is no account of what it envisages the weight of the road being, or the weight of the flyover. It is very difficult—indeed, impossible—to tell what minimisation looks like in this context. Does minimisation mean an absolutely negligible impact? I sincerely hope so. Either way, we deserve to have that information, so that we can ascertain whether the conclusion that the

“proposed scheme would have no likely significant permanent adverse effects”

is true, and if so, the extent to which it is true.

[Dr Murrison]

My hon. Friend is being very generous. Would he acknowledge that there is a clear and present danger, not only to people who live and breathe in villages such as Chitterne, with the rat-running that currently goes on, and Chicklade, which sits along the route of the A303 and is blighted by that road at the moment—their lives are being adversely impacted by the A303—but to the built environment, which is also being adversely impacted? We need to do something about that. The proposals for Stonehenge would go some way towards improving those settings, the lives of those who live there and the built environment in the sorts of villages I have described.

[Alex Burghart]

I thank my hon. Friend for those remarks. As I said to my hon. Friend the Member for North Wiltshire (James Gray) a moment ago, I fully understand the need for some form of road improvement in the area. All I am asking for is an assurance that we are doing everything in our power to protect the archaeological environment.
