Stonehenge tunnel: Salisbury by-pass considered as alternativepublished at 11:28
A southern by-pass of Salisbury is being considered as an alternative to a Stonehenge tunnel, the BBC has learned.
The government announced in 2014 that it wanted to build a tunnel alongside the World Heritage site.
A £2bn, 1.8-mile (2.9km) tunnel is the government's preferred option at Stonehenge but some archaeologists argue it could damage the ancient site.
