Challenge

Copper was appointed to deliver communications and stakeholder engagement for one of National Highways’ most complex and high-profile infrastructure projects: a proposed tunnel past Stonehenge, a globally recognised World Heritage Site.

The challenges were to:

  • overcome public skepticism and concerns following multiple failed proposals in the past
  • secure broad stakeholder buy-in across local, regional, national and international levels
  • conduct a robust statutory consultation in a highly sensitive and scrutinised environment.

Approach​

Copper’s support included:

  • positioning National Highways as the lead voice for the project to ensure consistency and credibility
  • developing a compelling narrative to explain a technically complex solution in an accessible, engaging way
  • promoting project benefits at multiple levels – local, regional and national – to resonate with diverse stakeholders
  • engaging a wide-ranging audience, including A303 road users, to demonstrate openness and encourage participation
  • ensuring communications demonstrated progress and delivery momentum, reinforcing confidence in the project’s viability.

Value delivered

  • Built strong public and stakeholder understanding of a complex, high-profile project, despite historical skepticism
  • Secured active support from Department for Transport ministers, helping position the campaign at a national level
  • Achieved global media coverage across major outlets (BBC, ITV, Sky News, CNN, China Daily), enhancing transparency and credibility
  • Gained endorsements from influential organisations including UNESCO, National Trust, English Heritage, RAC Foundation and local action groups
