What are we saving and why?

The 4-lane carriageway, tunnel and slip roads would cross the iconic Stonehenge World Heritage Site (WHS): a landscape that is considered “the most archaeologically significant land surface in Europe without parallel”.   The WHS is 5.4km (3.4 miles) wide but the proposal is for a 2.9km (1.8 mile) tunnel (see map below).

The massive tunnel portals and deep cuttings would cause irreparable damage to the WHS in breach of the UNESCO World Heritage Convention and ignores UNESCO’s firm advice.

We set up a petition in 2014 when the scheme was announced as part of a £15bn road investment fund.  Since setting up the petition, we have learned more about the recently discovered Mesolithic site at Blick Mead. This has led us to consider that if Government insists on a tunnel under the WHS, it must be long enough to avoid the WHS and its setting altogether. This would be in line with planning policy and World Heritage Convention safeguards. We cannot change the wording of the petition but road widening without further damage to the WHS is clearly expressed in the petition and its justification.
