A longer tunnel, a land bridge, extensive use of landscape haha's, a Fairy Rainbow? There is simply is no end to the endless line of pointless pitches thrown by the infrastructure landforming Heritage Industry Companies like Infandor, Colicon, Myrimmer, Pelladinnor etc. as they try and get their respective snouts in the Public Money Slurry Pool.
If the road annoys the stones then close the road and make people go round the long way. If it simply annoys some visitors then they must be told to get over it. And get over themselves. They built a crapulous visitor centre and a bus road which cuts across the Henge not once but twice. What a sham. English Heritage suggests a visitor should
"Watch the seasons pass and take a trip through time with our incredible "audio-visual 360 degree view from inside the Stones" in the visitor centre. Imagine what it feels like to stand in the middle of Stonehenge at winter and summer solstice, with this unique and memorable experience."
If visitors are being encouraged to imagine that lot above the Pan Pipes, Dream Catchers and Ambient Whale noise then they can surely imagine that the traffic on the A303 isn't there...

I'd like the M74 removed and diverted under a big tunnel as it interferes with the vibes at Wildshaw Burn.

K2 Plant Hire had the right idea. Enough of Stonehenge. It simply doesn't work properly any more. It has been broken down for years. Either let it crumble gently to dust or grind up the weathered old rocks, recast them with some industrial resin and reconfigure the place for a New Age. It'll cost a lot less than a tunnel or a Fairy Rainbow.
