History of the road
The Spanish roads in the twentieth century
tight curves, steep slopes and pavement dust given off both vehicles passing pedestrians and drivers could barely stand. So were the roads in the early twentieth century. For them circulating carts and wagons, carriages and stagecoaches. Nothing at that time did suspect that, very soon, these roads become obsolete, and that the whole society would require adaptation to the requirements of a fast and sophisticated driving the motor vehicle.
It is precisely in the year 1900 when the Spaniards contemplated for the first time, astonished, how curious vehicles circulated through the streets of their cities that did not need animal help to move: the car. And it has undoubtedly been this artifact - almost magical in its beginnings, so essential today - that has determined the history of roads, in Spain and throughout the world. These pages will try to vindicate the evolution of road infrastructures from their own progress and deficiencies, from their unique circumstances and their differential facts, but always relying on that inseparable friend who has conditioned, and will continue to condition their development.
Inventions of the eighteenth century
Although roads as such did not exist until the 1755th century, it must not be forgotten that some of the considered modern methods were discovered a few centuries ago. Thus, the legal and political Treaty of public roads and possadas, published in XNUMX, already speaks of the use of vegetable water, to "make a strong ground, which for the heras says Fray Miguel Agustín in his Agriculture, it is convenient to use, and not It is despicable for the Roads, it is to know, that the crumbled earth, and made dust, is kneaded with alpechin de azeyte, and then in being ready, tamp it, or level it with a cylinder, ultimately bolting it to sprinkle with the alpechin; and others , I say, do the same with ox blood and azeyte "(...)

After a period of international isolation, dollars also arrive in Spain, which even gets its membership in the United Nations Organization in 1955.
