Regarding the Stonehenge bypass, why not divert the A303 south east of Boscombe Down air eld and Amesbury, then west across the Avon, past Stapleford to an improved A303/A36 junction near Wylye.
The valley crossing will be tricky if a second Twyford Down is to be prevented, but there appear to be routes that avoid the conservation areas.
Doubtless uential residents will be offended, but the World Heritage Site would be completely bypassed.
There are other benets. A north-eastern bypass of Salisbury, taking A36 (Southampton-M4) trafc out of the city and Wilton, could join the new A303 east of the Avon.
As a result, the villages split in two by the A338 between Salisbury and the A303 would also be bypassed.
I've worked this up a bit in a brief paper, but my attempts to interest the Highways Agency and Salisbury District Council have met with polite indifference. As a highway engineer, - thankfully now retired - this is frustrating.
Could they still be persuaded, - and what about the National Trust, English Heritage and Wiltshire County Council?
