What's new
The road that made no sense
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 second part of the story, where we learn why exactly the M4 gets narrower on the final approach to Europe’s biggest city.
