Stonehenge: Tunnel Vision.

12 04 2024

In December 2014 the then coalition UK Government announced to great fanfare that the decades long saga of the on-again-off-again A303 Stonehenge Tunnel project would be revived once more.

The sound of zombie horses attempting the crawl away from yet another flogging pervaded the World Heritage Site, as first Deputy Prime Minister Clegg then Prime Minister Cameron descended on Stonehenge accompanied by the usual press, TV and English Heritage top brass.

A previous version of the project, estimated at £400M, had been cancelled several years earlier by a Government of a different colour on the basis of the cost, so it was somewhat surprising to learn that its reanimated corpse was now expected to require an eye-watering £1.7B – £2.5B.

To be fair, according to the plan this time the tunnel will be fully bored rather than cut-and-cover and will be somewhat longer. Not long enough, mind you, to go the full distance from the eastern edge of the World Heritage Site all the way to the western edge.

Instead, it will put its portals in the ground well inside the area of Outstanding Universal Value, obliterating whatever might be in the way.

A brand new dual carriageway will run from the western portal across 1k of farmland, sunk into a trench around 9m deep and 50m wide, to a new junction with the A360 at Longbarrow Roundabout.

At the eastern portal, the new dual carriageway will emerge to soar over the current A303/A345 junction at Countess Roundabout on a 10m high flyover, bringing 60mph HGV traffic noise to the delighted locals.

Almost 10 years on from the announcement, here’s where we are.

After an Enquiry in Public (where the independent Examiners decided against the whole idea), a doleful procession of vacant-eyed Secretaries of State for Transport (some of whom lasted less than 2 months in the job), a determination by one of them to approve the scheme’s Development Consent Order despite UNESCO’s and many others’ misgivings, a Judicial Review into that decision which found the Sec. of State had acted “irrationally” in doing so, then a “re-determination” of the application by a subsequent incumbent which again gave approval, and a further legal challenge (recently lost by anti-tunnel campaigners), we are now awaiting an impending appeal against that ruling.

Over a quarter of a million people have signed petitions against the scheme, crowdfunding an expensive ongoing legal process to the tune of hundreds of thousands of pounds.

UNESCO have threatened that Stonehenge World Heritage Site may be placed on the World Heritage in Danger register (a precursor to delisting) if the scheme goes ahead in its present form.

In the event that the tunnel does get built – estimated costs are now above £3B, and look likely to rise even more over the 5 years the build is optimistically slated to take – one certain outcome is that the casual view of a 4,500 year old global icon of prehistory from the A303 will be lost forever.

From being something freely glimpsed in the magnificent early dawn light surrounded by mist as you crest King Barrow Ridge making your way westwards, or appearing unexpectedly nearby, glowing rose-golden in the rays of the setting Sun as you head past it eastwards, it will become an experience only available to those who are either willing and able to pay the ever-increasing entrance fee or are lucky enough to be capable of walking the couple of miles from the nearest available parking or bus stop.

Meanwhile Stonehenge looks on impassively, perhaps whispering to those who will listen that humanity’s obsession with getting to the next traffic bottleneck a whole 8 minutes faster really may not be worth the cultural, let alone the financial, cost in the long run.

Section of A360 Road from Stonehenge to Salisbury will be closed for three months from 2nd April 2024

31 03 2024

A major A-road through Wiltshire will shut for three months during a significant roadworks project. Drivers warned of three month road closure ahead of A303 Stonehenge upgrade.

Motorists could face traffic carnage near popular tourist area with plans to close key road for three months

The A360 will close between its junction with The Avenue, near Salisbury, and the Longbarrow junction with the A303 from Tuesday, April 2.
During the closure, traffic will be diverted via the A345 and sections of the A303 and A36, as per the diagram below, and a comprehensive signage system is being developed to inform road users around Salisbury and as far away as Devizes and Shaftesbury to point traffic to alternate routes.

The busy route will remain shut for three months while works are carried out by Scottish and Southern Electricity Networks in relation to the planned A303 Amesbury to Berwick Down upgrade past Stonehenge.

National Highways said it would be “working hard” to minimise disruption before the summer

This scheme is being implemented on behalf of National Highways and will involve installing high voltage and fibre optic cabling along the road.

These cables will provide electricity for the major upgrade scheme on the A303, powering both construction and the planned tunnel in the long term.

A full closure is necessary during this period for safety reasons due to the narrow width of the road and the minimal spaces along the verges.

Work will be carried out seven days a week with some overnight working to allow the closure to be lifted before the school summer holidays.

National Highways says the works could have taken up to a year if single-lane closures and traffic signals were employed.

The diversion route will see drivers follow the A345, and sections of the A303 and A36, and National Highways has warned delays are likely.

Motorists have been advised to plan their journeys ahead of time and allow extra time to reach their destination.

Andrew Clark, National Highways’ project manager for the A303 Stonehenge scheme, says measures are in place to minimise the impact of the road closure.

He added: “The road scheme will ultimately tackle the longstanding issue of rat running and provide a real benefit to local communities, and for this essential preliminary work, we are doing all we can to put in measures to lessen the impact for local communities and the travelling public.

“We need to carry out the work now to maintain our programme, we appreciate that roadworks and road closures can be frustrating and we’d like to thank motorists, local residents, and businesses in advance for their patience.

“Without the full closure, the work would take a lot longer to complete, and working with Wiltshire Council, we’re making every effort to ensure that the impact on drivers and local communities is kept to an absolute minimum.”

What are the issues surrounding the proposed Stonehenge Tunnel?

28 01 2020

The Stonehenge tunnel is a proposed tunnel or sunken dual carriageway drawn up by Highways England to upgrade the A303 road, which currently passes within 165 meters of Stonehenge. Beginning with the closure of the A344 road, the Stonehenge tunnel would complete the removal of traffic from around the site by redirecting the A303 under Stonehenge. The project aims on one hand to improve the landscape around the monument, freeing tourists from traffic that detracts from the ancient wonder of the site and on the other improving the safety on the A303, resulting in smoother travel for anyone travelling to and from the south-west of England.

Stonehenge Tunnel

When it comes to the initiation and completion of this project there doesn’t seem to be much light at the end of the tunnel.

The proposed tunnel already has a long history of both bureaucratic and archaeological issues. Way back in 1995 was the first time it was proposed to build a tunnel for the A303 underneath the World Heritage Site. However, it did not take long for plans to be criticised for seemingly disregarding the archaeological significance of the Wessex landscape. It was suggested that the tunnel approach would cut in to a prehistoric track way between Stonehenge and a nearby river, resulting in the loss of archaeological remains which would harmfully affect the authenticity of the site and more than cancel out the benefits of the proposed tunnel. After years of bureaucratic wrangling the proposal was finally accepted by the Government on 12 January 2017. Today, the tunnel remains mired in controversy and the arguments against it haven’t changed much since the idea’s inception in 1995. The main issues with the proposal seem to be its staunch opposition from several parties, the complexity of the job and its price.

Opposition

The staunchest opposition to the tunnel is represented by the Stonehenge Alliance campaign group ‘a group of non-governmental organisations and individuals that seeks enhancements to the Stonehenge World Heritage Site’. This group includes environmentalists, archaeologists, residents and have recently repeated their belief that the proposed tunnel “would cause irreparable damage to the landscape”. They believe that the world heritage site of Stonehenge should be considered far wider than the barrow on which the stones stand:

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… would result in at least 1.6 km of above-ground 21st-century road engineering…

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.

Cost

In 2018 Highways England proposed a cost of £1.6 billion and a planned start date in 2021 was indicated with the tunnel’s planned opening being in 2026. Unsurprisingly, this cost has created yet more opposition in both the commons and amongst the general public especially since the project was due to be privately funded, but now will be funded publicly since the government dismissed a ‘PFI financing model’ in the 2018 Budget.

Complexity

To protect the landscape, the plans are ambitiously complex. Not only is the job of sinking a dual carriageway a complex starting point but the project also proposes:

  • Four “green bridges” for wildlife to cross the dual carriageway.
  • Restoring areas of chalk grassland at Yarnbury Castle on Berwick Down through to the south of Parsonage Down national nature reserve.
  • 100ha of new chalk grassland to promote biodiversity in the area.
  • A viaduct at the River Till
  • Moving the junction between the A303 and A360 600m west

Adding a bureaucratic layer to the complexity is the fact that  all UK tier 1 contractors have refused to bid the job believing the current approach to be too complex with its shallow tunnel, complex geology, rabid opposition,  and huge public scrutiny because of both the cost and the environmental concerns.

Of course, all these issues are interlinked. The complexity of the job is a demanded by the opposition to protect the natural beauty of the area, but the complexity pushes up the price and then the price creates yet more opposition. It seems to be a vicious cycle. When it comes to the initiation and completion of this project there doesn’t seem to be much light at the end of the tunnel.
