In France, Lyons, in the mid-Rhône valley, was a great centre for the radiating roadways of Gaul. Strategically it was important then as it is important now, and Roman soldiery of the past, as the automobilist of to-day, had here four great thoroughfares leading from the city. The first traversed the valleys of the Rhine and the Meuse; the second passed by Autun, Troyes, Chalons, Reims, Soissons, Noyon, and Amiens; the third branched in one direction toward Saintes, and in another to Bordeaux; while the fourth dropped down the Rhône valley direct to Marseilles.
More than thirty thousand kilometres of roadways were in use throughout Gaul during the Roman occupation, of which the four great routes (viæ publicæ) formed perhaps four thousand.
Of the great highways of France, the Grandes Routes Nationales, of which all travellers by road have the fondest and most vivid memories, it is well to recall that they were furthered, if not fathered, by none other than Napoleon, who, for all he laid waste, set up institutions anew which more than compensated for the destructions.
The great roadways of France, such as the Route de Bretagne, running due west from the capital, and those leading to Spain, Switzerland, Italy, and the Pays Bas, had their origin in the days of Philippe-Auguste. His predecessors had let the magnificently traced itineraries of the Romans languish and become covered with grass—if not actually timber-grown.
The arrangement and classification laid down by Philippe-Auguste have never been changed, simply modified and renamed; thus the Routes Royales—such as followed nearly a straight line from Paris by the right bank of the Loire to Amboise and to Nantes—became the Routes Nationales of to-day.
Soon wheeled traffic became a thing to be considered, and royal cortèges moved about the land with much the same freedom and stateliness of the state coaches which one sees to-day in pageants, as relics of a past monarchical splendour.
Louis XI. created the "Service des Postes" in France, which made new demands upon the now more numerous routes and roadways, and Louis XII., François I., Henri II., and Charles IX., all made numerous ordinances for the policing and maintenance of them.
Henri IV., and his minister Sully, built many more of these great lines of communication, and thus gave the first real and tangible aid to the commerce and agriculture of the kingdom. He was something of an aesthetic soul too, this Henri of Bearn, for he was the originator of the scheme to make the great roadways of France tree-shaded boulevards, which in truth is what many of them are to-day. This monarch of love, intrigues, religious reversion, and strange oaths passed the first (and only, for the present is simply a continuance thereof) ordonnance making the planting of trees along the national highroads compulsory on the local authorities.
Under Louis XIV., Colbert continued the good work and put up the first mile-stone, or whatever its equivalent was in that day, measuring from the Parvis de Notre Dame at Paris. Some of these Louis XIV. bornes, or stones, still exist, though they have, of course, been replaced throughout by kilometre stones.
The foregoing tells in brief of the natural development of the magnificent roads of France. Their history does not differ greatly from the development of the other great European lines of travel, across Northern Italy to Switzerland, down the Rhine valley and, branching into two forks, through Holland and through Belgium to the North Sea.
