"but it is a cultural icon and it is afforded a great deal more protection that Tara"

Weeeell, that might have been sort of true last week in that in the case of Stonehenge they were going to bury the road at least, but this week??? Burying the road by a deep bore tunnel is too expensive it seems. So what's left, apart from carrying on with the congestion? Reverting to cheapo, immensely damaging cut-and-cover tunnelling?

Which monument would have been best protected then? I wonder if the timing of the Stonehenge re-think is entirely unconnected with Tara? And let's face it, this isn't a rethink, this is a signal that the best three options are too expensive so only the worst one is on the table.
