A303 Stonehenge Tunnel

You are here: Home - Futures - A303 Stonehenge Tunnel

Scheme Outline

New three kilometre dual-tube bored tunnel to carry the A303 past the National Trust and World Heritage Site of Stonehenge. This will both remove traffic from the existing A303, which runs just a few yards from Stonehenge itself, and provide additional capacity as the existing road is single carriageway. The scheme includes improvements close to the site also, including a bypass at Winterbourne Stoke and a flyover at Countess Roundabout.

As the timeline below demonstrates, Stonehenge is actually the young upstart at this location. Some suggest that the A303 should remain in situ as the original historic monument, and Stonehenge should be put out of the way underground...

On 6 December 2007, the Department for Transport announced that the Stonehenge Tunnel scheme, and all associated works including the flyover at Countess Weir roundabout, the new Stonehenge visitor centre complex and the Winterbourne Stoke bypass have all been cancelled. The scheme up to this point was the result of more than ten years of investigations, consultation and planning. It is not clear what the next step will be, both for Stonehenge as a World Heritage Site that deserves better than a trunk road on its doorstep, and also for Winterbourne Stoke whose residents have been awaiting relief from A303 traffic for decades.

The decision appears to have come at the Ministerial level. It is incredibly rare for such a high-profile scheme as this to be cancelled so late in the day.

Department for Transport announces larger-scale project including a bored tunnel as part of £5.5bn of road improvements.
2004
Public enquiry. The scheme may yet be altered to include a longer tunnel.
