1922 MOT map of France
Having done MOT maps of Great Britain and Ireland, how about the country that inspired road numbering in the first place?
Under "Other historic maps", there's now a "1922 France" layer. This was produced by the Ministère des Travaux Publics in 1922 and is described as: Carte Itinéraire des Routes Nationales de France et D'Algérie avec les Chemins de fer d'intérêt général et les Voies navigables - National Road Itinerary Map of France and Algeria with railways of interest and navigable waters. It's basically the French equivalent of an MOT Map, although conceptually more like the early Ten Mile Road Maps of the 1930s.
As French Route Nationales have been comprehensively detrunked, particularly with two exercises in 1973 and 2006, it's much more difficult to identify the older routes, some of which date from Roman Gaul, and others were staked out by Napoleon, so there's a lot of history in there.

Wow, thank you. The other really interesting thing about the map is how important canals are, not just the roads and railways!
Is there a road improvement project going on near you? Help us to document it on the SABRE Wiki - help is available in the Digest forum.

Re: 1922 MOT map of France
This is awesome. It’s astonishing to see how many Route Nationalés there are on the map which have now been reclassified as D roads, particularly in the north.
IIRC France never used a zoning system but allocated its roads in a clockwise sequence, with RN1 to RN24 radiating from Paris (some started further away). RN25 and above were used for cross-country routes avoiding the Capital, which also used a clockwise sequence starting and ending at the mouth of the River Seine.

French road numbering doesn't really have a system, other than the original 20 radials from Paris I've never worked out the system for N roads, and the 1973/2006 exercises have made it even harder.

Re: 1922 MOT map of France
France has never really gone for road numbers in the same way Britain has - that's how they could do the 1973 detrunking without sufficient people being particularly bothered. I believe the convention is - when you see "Toutes directions", follow it. When you see "Autres directions", follow it and pray.
The most intact N roads are, obviously, the ones where the geography makes it impossible to run a motorway through the area; however, even then the former N6 through the Col du Mont Cenis (one of Napoleon's roads through the Alps) is now a D road.

Re: 1922 MOT map of France
The original Paris-Brest route was on the N12
The Audax Club Parisien have moved the Randonee from it for obvious reasons but the Union Audax Francais still use it (because they ride in large groups with a safety van at a steady 22kmh)
https://twitter.com/davidguenel/status/ ... 3936000012
When planning the ride down and back I got the advice to look for Department roads with one or two digits as the downgraded N roads would be 3, 4 or 5 digits.

Re: 1922 MOT map of France
I think of it as a spiral from N1 to N20, and then spiral-cum-clustering system after that. As you say, there are 20 radials; after that, it looks like they worked their way clockwise around the map, using up N21-N24 in a continuation of the spiralling radials but without the roads actually reaching Paris, and then from N25 onwards clustering clockwise with the River Seine as the 12 o'clock position.
And I have driven it, several times, because it is my favourite route into Italy! I cannot recommend it highly enough to all fans of continental roads.Ritchie333 wrote: ↑Mon Feb 24, 2020 14:09 The most intact N roads are, obviously, the ones where the geography makes it impossible to run a motorway through the area; however, even then the former N6 through the Col du Mont Cenis (one of Napoleon's roads through the Alps) is now a D road.
Come to think of it, as of last September I have now driven over the Franco-Italian border on what used to be the N5, the N6, and the N7. There is a beautiful old-style N7 signpost still in place at the start/end of the latter. One day I'd love to do the whole of the former N7...
Other great French drives I've done include the N4-N44 from Strasbourg to Rheims, the D619/N19 from Troyes to Belfort, and the former N71 (both ways) between Troyes and Dijon. I've got a hankering to complete the N4, and to do the N2, N10, N12 and N20 too.
Over the border I've done the Italian SS20 from Cuneo to Ventimiglia through the Col du Tende. In Cuneo there's a lovely old sign pointing to Ventimiglia, which is possibly old enough to date from the time before the border was changed following the Second World War (the route always took you into France and back, but the adjustment to the border made the French section of the road longer). I might have a picture of that sign somewhere....

Re: 1922 MOT map of France
I've also noticed that, since map is from 1922, it pre-dates the post WWII Italian Peace Treaty, and thus the N6 crosses the border at the summit of the Col du Mont Cenis, as opposed today where the crossing is some way south of it.

Re: 1922 MOT map of France
It helps that Paris is fairly central, London is one of the most off-centre capitals in Europe.Vierwielen wrote: ↑Thu Mar 23, 2023 23:09This seems to be an old French trick - they did the same with the arrondisements of ParisOwain wrote: ↑Wed Feb 26, 2020 04:53I think of it as a spiral from N1 to N20, and then spiral-cum-clustering system after that.

As the Autoroutes were built the N roads they were replaced were downgraded to departmental level.

Re: 1922 MOT map of France
For what it’s worth, that downgrading mostly occurred in 2006, well after most autoroutes were built. If you look at the evolution of the Route Nationale net: they greatly expanded it in the 1930s, with many routes of rather limited importance - but it allowed building roads fit for cars there is the most efficient way using national funding programs. These RNs were then generally downgraded in 1973, for their lack of importance. But formerly important roads that had lost their importance to a nearby motorway were left, also because of political infighting on the very topic of toll roads - there has to be a toll free alternative.
The downgrading of 2006 was based on a thinking that the state only needed to maintain N-routes to connect regions not served by the motorway network. That was the end of some major corridors like N6 and N7.

Paris is fairly central on an east to west axis, but is definitely in northern France.RichardA626 wrote: ↑Fri Mar 24, 2023 23:11It helps that Paris is fairly central, London is one of the most off-centre capitals in Europe.Vierwielen wrote: ↑Thu Mar 23, 2023 23:09This seems to be an old French trick - they did the same with the arrondisements of ParisOwain wrote: ↑Wed Feb 26, 2020 04:53

Re: 1922 MOT map of France
While London might be pretty off-centre, I think that Slovakia takes the prize for the most off-centre capital in Europe - its suburbs stretch to within a kilometre of its border with Austria and come within 10 km of Hungary.RichardA626 wrote: ↑Fri Mar 24, 2023 23:11It helps that Paris is fairly central, London is one of the most off-centre capitals in Europe.Vierwielen wrote: ↑Thu Mar 23, 2023 23:09This seems to be an old French trick - they did the same with the arrondisements of ParisOwain wrote: ↑Wed Feb 26, 2020 04:53

Japan says: Hold my sake!
Japan's roads are numbered more-or-less as somebody pulled a number out of a hat. Almost as bad as housing numbering, which is in the order the buildings were built.
