Here are two much clearer maps of Wales -
Motorways and dual carriageways
Railway network
We could easily wander off into a lot of history, so I’ll hope you’ll forgive me bringing in a bit more of that.I believe it's something of an urban myth that freight traffic vanished off the rails because they somehow weren't suitable,
How much of that convenience was effective subsidy via externalised costs though? Railways were at that time privatised and use of them was charged to recoup construction and maintenance costs. Roads were provided by the government and then used by lorries for close to free, on top of that there were the greater air & noise pollution along with casualties from collisions. Developed into a classic tragedy of the commons example much like car use has.
Roads in the 1930s were a result of government, private and local parish authority investment, so like the railways most people had paid for them, directly or indirectly. The railways caused the collapse the Turnpike trust system, the CTC were one of the first bodies to lobby government for the improvement of roads at the end of the 19th century.Stevek76 wrote: ↑11 May 2023, 10:31amHow much of that convenience was effective subsidy via externalised costs though?

The "motorways and dual carriageways" image seems like a work of fiction. It includes the eastern A47, southern A46 and I think the A49 which are mostly single carriageway, often through many towns and villages. It shows parts of the A303 which are still single carriageway. And those are just the ones which leap out. It may have been created by someone trying to mislead people into thinking that the South East hasn't got lots more higher-spec "National Highways" than the rest of England.
It's a lousy map in every way, but the best I could find online in that format, at the time. Looking again, it's not worthy of its title. If you know of one which better shows twin carriageway roads please send a link or picture.mjr wrote: ↑23 May 2023, 3:26pm The "motorways and dual carriageways" image seems like a work of fiction.

In theory, it should be possible to extract a map of divided carriageways from OpenStreetMap using Overpass Turbo or similar, but doing that in a reasonable time is beyond me.Biospace wrote: ↑23 May 2023, 4:56pmIt's a lousy map in every way, but the best I could find online in that format, at the time.

There seems to be a lack of maps differentiating between single and twin carriageway roads.
