A lot has happened here in just a few months. Traffic through the interchange is now passing under the completed bridge on the east side of the roundabout, which now allows the original line of the A674 to be broken up and the other bridge to be built. On the right, the A674 towards Blackburn has been diverted to its new course. On the left, the A675 Bolton Road takes a convoluted course to allow reconstruction of its approach to the junction.

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.
The forever bottleneck, part 1
The M4 into London was one of the UK's earliest and most ambitious motorway projects. It was bold, pioneering... and almost instantly regretted.
