A principal aim of the scheme is to remove the roads and heavy traffic, with their associated noise and disturbance from the vicinity of the stones and to reunite Stonehenge with its surrounding monuments in their natural chalk downland setting. This involves removing the road and its traffic completely from within sight of the stones, with the locations of the tunnel portals being beyond the visual horizons from Stonehenge.
A programme of archaeological surveys has been developed with input from an independent Scientific Committee, which comprises some of the country’s most eminent archaeologists. The project also has a Heritage Monitoring and Advisory Group comprising Historic England, Wiltshire Council Archaeology Service, English Heritage and The National Trust. The Scientific Committee and Advisory Group will continue to have oversight of all the archaeological findings as the scheme develops.
