Historic process

Since 1991 the Highways Agency, Government and various stakeholders have been considering a scheme to build a dual bypass at Winterbourne Stoke, together with a change in route for the A303 intended to put Stonehenge back into a more appropriate setting and environment.

By the end of 1993 it was agreed that a tunnel should replace part of the A303 skirting Stonehenge to hide the road beneath the landscape. A 500m long cut and cover tunnel was suggested.

Many archaeological groups were keen that the tunnel be much longer, to get the full benefits, so further route identification and study took place and the Agency was put under pressure to look at alternatives.

'Many were keen on a 4km long tunnel scheme, ' explains Bradley, 'but at that time Halcrow calculated that 4km was not feasible - mainly due to a £300M price tag.'

But by 1998 the economic climate had changed in the scheme's favour. Discount rates had dropped, prompting English Heritage's advisor Ove Arup to come forward with a scheme that followed a northern route around Winterbourne Stoke, and included a 2km cut and cover tunnel.

Lord Whitty announced the preferred route in June 1999.
