Roman Roads Research Association (UK) (romanroads.org)

It's quite weird having local footpaths and paved roads that turn out to have been constructed by the Romans originally - around here that also applies to canals, drainage ditches, etc. It just blends into modern reality.

I imagine some of the Roman stuff was built on even older roads and channels.

Man I love LiDAR, on another note we need to LiDAR the entire amazon forest bc of what is just waiting to be discovered
