"I'm not sure when the 2.1km bored tunnel became the 'damaging' option (compared to the other options) but three cheers for English Heritage, the British Museum, the Society of Antiquaries and the UK National Commission for Unesco for supporting it - there's still a bit of sense and responsibility out there!"
Hang on. Is this the same EH that supported the horrendous "cut and cover" tunnel idea for years? And then said the long tunnel was best? And now says the short tunnel is the best, simply because the govt. won't cough up the money for the long one? In what sense are you using the term "sense and responsibility" Mr L.?
The NT are simply saying the Stonehenge complex ought to be the priority and if you can't spend enough money on a scheme that minimises damage to that then maybe you shouldn't do anything at all.
We can argue till the cows come home whether that's truly responsible but I'll bet you a quid that the next ten generations will say it was, and they're the ultimately authoritative arbiters, not today's commuters.
