A Road (n.) that is blocked already contains the team that will clear it: travellers stopped one by one by the same boulder pile up into a crowd, and that crowd is the push that moves the boulder.
The Road (n.) was invented as a stable object by the Romans, which is why all roads lead to Rome: it gave shape to the image of power, a seat in Rome fed by the provinces through a constant flow of goods and people.
A Road (n.) ages in its own way: a Roman road dies one flagstone at a time, a modern one in long waves and buckles, because each formula of compatibility has its own way of falling apart.
The Road (n.) as a network outlived the empire that built it because it went beyond the purpose of every single trip and took in a piece of nature along the way.
A Road (n.) sends outposts into the wild around it: bridges, viaducts, tunnels, hedges and avalanche walls, planted sometimes at great distances, to make peace with a terrain it does not control.
