"Blick Mead site connects the early hunter gatherer groups returning to Britain after the Ice Age to the Stonehenge area, all the way through to the Neolithic in the late 5th Millennium BC.
"But our only chance to find out about the earliest chapter of Britain's history could be wrecked if the tunnel goes ahead."

According to others the Blick Mead site is over a kilometre away from Stonehenge and hardly likely to be affected. Given the visitation by Icomos and Unesco last week, their interest will not necessarily be with the wider landscape though, Stonehenge stone circle sits in its landscape the sole extant visible monument for tourists to see.
So if you believe the news you read, or put it to one side till the next 'newsworthy' item comes along, they are like waves rolling up to the shore, all important at the time but they slip once more back into the sea.
And, if I was to venture an opinion, quite like this bit of news, the tunnel will cost over a billion pounds to build, but there are other options of course......
