State highways (Italy) in the context of "Salarian Way"

The Via Salaria was an ancient Roman road in Italy.It eventually ran from Rome (from Porta Salaria of the Aurelian Walls) to Castrum Truentinum (Porto d'Ascoli) on the Adriatic coast, a distance of 242 km. The road also passed through Reate (Rieti) and Asculum (Ascoli Piceno).

Strada statale 4 Via Salaria (SS4) is the modern state highway that maintains the old road's name and runs on the same path from Rome to the Adriatic Sea.
