  • Reinstating a rural landscape of gentle rolling chalk downland
  • Allowing wildlife to move freely above the tunnel and across green bridges
  • Creating new chalk grassland and enhance biodiversity


  • Returning life in the village of Winterbourne Stoke to its previous peaceful existence
  • Removing rat-running traffic in local villages making it safer and easier for people to go about their daily lives
  • Making journeys between different parts of Amesbury easier by taking the A303 over Countess roundabout
  • Improving connections for cyclists, walkers and horseriders by creating new rights of way

Our legacy

The design of our scheme will deliver enormous benefits. But we want to do more. We aim to leave a lasting legacy that will benefit local residents and visitors alike. Whether that’s looking at new cycle paths, creating apprenticeships or helping to attract sustainable tourism.

We have already started working with local stakeholders, organisations and groups to identify the best areas to concentrate on. Our Community Forum is helping to shape the legacy too.
