London

London’s notorious orbital motorway turns 40 years old today. Where did it come from - and why the number “25”?

The one great attempt to make London’s streets logical - and how one retired chauffeur’s favourite routes changed the way you get around the capital.

What might it have been like to stand in one spot and witness the arrival, and the uncertainty, of plans for an urban motorway in West London?

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

An early triumph of the motorway programme, the M4 between Chiswick and Langley linked Central London to Heathrow - then still known as London Airport - and was the start of a new motorway west.

It was specially designed never to be noticed. And now it's disappearing, nobody has noticed its absence. It's London's own bespoke street light.

The Silvertown Tunnel is finally open for business. One question remains: what’s it for?

Road numbering is a system with clear rules. What happens when the people responsible for numbering roads don't follow them?

A national system of road numbers radiating from a central point suggests there is… well, a central point. But if you go looking for it you’ll find it doesn’t exist.

Last year we reported on an experimental "3D" zebra crossing. It turns out they're multiplying... if you know where to look!

The next set of pages in our Ringways series are now online, documenting motorways in and out of London to the north and east.

The next pages in our series on London's unbuilt motorways are now online, charting the strange story of Ringway 3.

The Ultra Low Emission Zone is now in force across Central London. What does it mean for you? And what's next?

Some 3D paint tricks mean one London zebra crossing is no longer taking its job lying down.

The next set of pages exploring London's unbuilt motorways are back online, this time looking at the reviled Ringway 2.

The capital's planned new river crossing faces opposition at every turn. Why has it always been so hard to find new ways across the Thames in East London?

A hugely destructive but largely forgotten urban motorway scheme, celebrated here by its architects in the book that marked its opening.

The Western Avenue Extension - opened as A40(M) and known as the Westway - was much hated when it opened, but there's no sign of that in the official book published to mark its opening.

The M25 is either one of the greatest transport achievements of the 20th century or one of Britain's largest planning failures, depending on which way you look at it. This booklet takes the former view, celebrating the completion of the circuit in 1986.
