The Stonehenge World Heritage Site, which houses well-known prehistoric monuments, is under threat with the British Government wanting to plunge a two kilometre, $3 billion tunnel underneath it.

The monoliths are right next to the A303 Highway, which connects London with south-west England, and the proposal by Highways England to replace the iconic monuments with a tunnel puts archaeologists in a position that goes against the Stonehenge’s current custodians, English Heritage.

Stonehenge Director, Kate Davies, says "this is supposed to be a tranquil, ancient monument [but] unfortunately, the blight of traffic really impacts upon the setting.

"It's a very noisy, visual intrusion on the landscape."
