No it's not just you.

Being cynical it strikes me this just might be a bit of window dressing related to the proposed closure of the A303 at Stonehenge.

This:
"This would protect the archaeology, enhance the setting of the West Kennet Avenue and the Henge, restore their interrelationship and provide a good quality walking environment "
..... sounds awfully like the "restoring the integrity of the central area of Stonehenge" guff currently squirting out of every official orifice.

Anyway, it won't happen. It's something they can amuse themselves with for a while before having to quietly shelve it!
