Belfast to Dungannon
Completed in the 1960s and not changed much since, the Northern Ireland M1 is a mostly two-lane affair that stretches to nearly 40 miles - the longest stretch of road of this standard in the province.
One hard shoulder's enough for one carriageway, right? Well...not according to one long-lost design standard.
An introduction to what I write, and why I write it, and where my strange new road sign simulator fits in to all this.
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 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.
The road that connects Wales together, but which nobody really uses... All five hours of the A470, from Llandudno to Cardiff, are here.
