# Salt Road

A salt road (also known as a salt route, salt way, saltway, or salt trading route) refers to any of the prehistoric and historical trade routes by which essential salt was transported to regions that lacked it. From the Bronze Age (in the 2nd millennium BC) fixed transhumance routes appeared, like the Ligurian drailles that linked the maritime Liguria with the alpages, long before any purposely-constructed roadways formed the overland routes by which salt-rich provinces supplied salt-starved ones. == Roads == The Via Salaria, an ancient Roman road in Italy, eventually ran from Rome (from Porta Salaria in the Aurelian Walls) to Castrum Truentinum (Porto d'Ascoli) on the Adriatic coast - a distance of 242 kilometres (150 mi).
