As an improvement to the UK's motorway and trunk road network it was a vast expense and unjustifiable. One can always find something more expensive that the government is supporting to beat them with such as the Olympics, rail "privatisation", etc.
The solution is surely to close the road that divides the visitors centre and the stones together with a conventionally dualled A303 with some imaginative earthworks and landscaping that would achieve a considerable improvement.
I'm not a philistine to ancient history and architecture and I appreciate that the infrastructure serving the site needs improving but English Heritage needs to adopt a sense of realism. Visitors from all over the world travel to a site where the supporting experience is tatty and English Heritage has nothing to show for decades of entrenched position.
