@infobeautiful American CW is that a farthing width of the top layer is spag bol

@infobeautiful TIL: The world-spanning British Empire ultimately failed because it was built on a foundation of chalk.

@infobeautiful

Next batch of societies will be able to include the chewing gum layer.

@infobeautiful is the pic from the 80's? The "modern car" is a sports car, not a SUV.

@infobeautiful Kula Shaker have a song about this road- the A303. Its the main road into south west England. https://m.youtube.com/watch?v=LCJlqBuu32s

@infobeautiful This road has seen many a traveller. King Arthur himself found solace in the ale houses along this thoroughfare.

@infobeautiful I can only assume that there haven’t been many UK-based respondents to this… as they would all be making pothole-related comments ‍

(justifiably, as it has been a relentlessly-wet winter, leaving many UK roads in appalling condition)

@infobeautiful

I'd only seen photos of Roman roads made with flagstones.

Hadn't realised that some were aggregate.

Now wondering why only flagstone photos get widely distributed.

@infobeautiful Whenever I come across the A303, I always think of the film 'Wag the Dog,' so let me take this moment to say: if you've not seen it, it's a brilliant and darkly funny film and you should watch whenever you next have the chance.

@infobeautiful

Where is that exhibit housed, please.

@infobeautiful
There's a layer of bicycles on the surface that became used by cars.

@infobeautiful 🤌🤌

@infobeautiful It would be good to credit the museum when posting things like this. This seems to be an exhibit at the Haynes Motor Museum: https://www.facebook.com/HIMM.co.uk/videos/a-slice-of-the-a303-%EF%B8%8Fhave-you-ever-wondered-what-exists-beneath-the-road-you-dri/967806094875025/
