Are there other examples of similarly old roads or routes that are still in use today? I know of the Grand Trunk Road [1] and other examples would be cool to learn about.
Vía Augusta, from southern Spain up to Rome. Via claudia Augusta, from Germany to Rome. El camino Real, in America (Mexico and USA, also 2500km approx)
