This statement by EH:
"Both the published scheme and the new visitor facilities need to be delivered in full if the UK is to fulfil its responsibilities under the World Heritage Convention, English Heritage said."

The govt. has just said OK to the visitors centre but ONLY if the road scheme (i.e. the tunnel probably) goes ahead.
How does that translate into the official guardians saying we support the tunnel? It's a different issue.
Also, how come the tunnel is "essential if the UK is to fulfil its responsibilities under the World Heritage Convention"? I thought it was one of several schemes thought up by and under the budget of the Dept of Transport to relieve traffic congestion. EH might well be justified in supporting one of the other options, like a bypass or doing nowt, on World Heritage grounds, but a tunnel, with massive cuttings dug into the World Heritage site at each end? Why that? Well, see paragraph 2.
Something ain't right.
