The M271 shifts traffic around the west of Southampton, connecting the motorway to the western suburbs and the A33. It isn't a big job, and yet somehow the M271 gets it all wrong.
The wait is over! The full map of the Ringways, London’s unbuilt urban motorway network, is now online. Not even the system's planners had anything like this.
It makes the traffic situation in one part of West London much more bearable but it should have been removed more than quarter of a century ago. It's amazing what you can do with a big Meccano kit.
