This is so confusing I had to view it from top down perspective and I still have no clue how you would navigate through this.
It looks like a vehicle approaching the Magic Roundabout via A4312 can use the outer ring to exit via B4289 or Fleming Way but any other exit the vehicle must spin in circles to enter the inner ring. I give up.
There's only one Magic Roundabout. It was the result of an open tender and I think that the winning team was from a local college. There were five roads leading into a weird space and it needed fixing. It's not as bad as it looks. Actually, it is as bad as it looks when you first encounter it.
The centre (which doesn't really show up on Goog maps) goes anti-clockwise, bear in mind that we drive on the left and go clockwise around a roundabout usually. You can use the outside to avoid the centre completely, which is often faster. The main problem is that it is very heavily used and hence some of the markings are scrubbed out. Also it is easy to get disorientated but even if you fly out of the wrong exit, it is easy to use a side street later to get back on track.
I have to say that I would not recommend visiting Swindon to someone who usually drives on the right hand side. To be fair I don't really recommend Swindon to anyone 8) For me, the MR is the exciting end to a two hour drive to visit a customer - just what you need to wake you up at ~0930.
It's very simple: yield to people making a left from Shrivensham, then enter the first roundabout. The internal circle is not a roundabout, people already inside will yield to you. So you can continue going forward (over the KEEP CLEAR area) and navigate around the center anti-clockwise. You yield again to people from Shrivensham and depending on what exist you want you need to traverse another one or two roundabouts and exit the desired road.
Are these common?
