When Helen Ghosh said in the Telegraph; http://www.telegraph.co.uk/news/2017/02/08/stonehenge-tunnel-plan-given-backing-english-heritage-national/
"We are encouraged by the proposals put forward by Highways England for consultation but it is very clear that there's still more to do."
By saying 'more to do' does she mean the provision of a green land bridge near the western tunnel portal? I would say she does, following on from the National Trust's experience of A21 at Scotney Castle in Kent, although they are not saying that at the moment. Although the battle lines are still being drawn - this granny trick needs to be highlighted. They will say look we made a 'compromise', so hey lets get continue with the proposed timetable - even though in reality the scheme would still involve scarring a massive dual carriageway through a large section of the WHS.
