Lagan Bridge
Belfast to Ballymacarrett
The M3 is fairly obviously just the last mile of the M2, built in the 1990s when a new crossing over the Lagan was required. Not that anybody pays any attention to its number anyway.
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 introduction to what I write, and why I write it, and where my strange new road sign simulator fits in to all this.
