If you want to avoid driving in Edinburgh, don't worry. There's a fast dual carriageway all along the urban fringe to help you avoid it. It's called the A720 Edinburgh City Bypass.
It was the UK's only single-carriageway motorway, and twenty years ago it ceased to exist. This is the story of the strange fascination it held, and of my place in history.
The very first motorway was eight miles of relief for the Lancashire town of Preston. It goes without saying that there's an interesting story to be told about it.
