I see that Dr Murrison appears to be backing the Stonehenge tunnel, at what cost we are not yet sure, only that it is part of a £2 billion plan for the A303.

It must be a very large chunk of that sum, perhaps as much as half. To spend about £1 billion on a tunnel is surely monumental folly when we are looking forward to an extended period of austerity.

In the same edition of the Times, you report that Wiltshire Council cannot afford to keep paying just £70,000 per year to keep the speed indicators on our roads. How does Dr Murrison view this contrast?

As Stonehenge is a World Heritage Site, perhaps the appropriate answer would be for the world to contribute the excess cost over what a surface bypass would cost?

But the world has real problems, like ebola and climate change, to deal with first.

In my view, the archaeology lobby should be asked to be realistic and accept a surface bypass that might be afforded.

At about half-a-mile south, it would be hidden from view by the landscape and sufficiently far enough away from the Woodford valley not to be a nuisance to most residents there.

Further study and discussion costs on the tunnel, which is unlikely to be afforded, would be unjustifiable.
