LONDON (AP).- Stonehenge is getting a multimillion-pound grant that conservators say will help restore some dignity to a World Heritage site blighted by busy roads and cramped facilities. English Heritage said Friday that it now has about two-thirds of the money it needs to revamp the area around the prehistoric circle of stones, although the group acknowledged the improvements probably wouldn’t come in time for the 2012 Olympic Games, when hordes of tourists are expected to descend on the site. Built between 4,000 and 5,000 years ago, Stonehenge is one of the world’s most recognizable sites. But the monument’s vista is blighted by two busy roads, one of which runs right by it. Stonehenge’s visitor center is also inadequate, with vehicle traffic spilling out onto the grassy area nearby during peak periods. There’s only one outdoor refreshment kiosk to serve the nearly 1 million visitors who see the site
