An archeologist has said he is "devastated" after Highways England allegedly damaged a sensitive site near Stonehenge.
Say, it's Blick Mead is about a mile from the famous tourist attraction.
Part of the site is a platform of the prehistoric cattle known as aurochs.
But Highways England engineers are accused of damaging a hole 3.5m (11.5ft) deep through the platform to monitor.
If the tunnel goes ahead, the water goes back to the water.
Archeology Professor David Jacques, from the University of Buckingham, discovered the site and the agency's actions as a "travesty".
Had been the platform.
He told Sky News: "I am absolutely devastated.
"Thousands of years ago these people went to enormous lengths to preserve this area, and with one careless move, the Highways Agency has undone all their hard work.
"This is a disgrace."
Earlier on Thursday. he had said that there could also be footprints at the site which would be "the earliest tangible signs of life at Stonehenge".
He added: "If the remains are not preserved we can not be able to understand why Stonehenge was built."
But Highways England told Sky News it had no evidence of damage being caused by the drilling of the hole.
A spokesman told Sky News: "We do not have any other evidence that our monitoring, the location of which we shared with Professor David Jacques, has caused any damage to the site.
"At Prof Jacques' request, we have been monitoring the conditions.
"We asked for information on the locations of water monitoring stations in early November.
"We have adhered to guidelines in carrying out the work, with an archeologist on site, and with two care being exercised at all times."
The proposed tunnel is part of a £ 1.6bn upgrade of the A303, which connects the M3 from London to the south west of England.
The Inspectorate for Examination and Work is Two to Start in 2021.
