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 242Â 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.
The Tronto (Latin: Truentus) is a 115-kilometre (71Â mi) long Italian river that arises at Monti della Laga and ends in the Adriatic Sea at Porto d'Ascoli, San Benedetto del Tronto. It traverses the Lazio, Marche, and Abruzzo regions of Italy.
The source of the Tronto is in the Monti della Laga mountain range in the province of Rieti. Monte Gorzano is north of the source of the river and Lake Campotosto is south of the source of the river. The source of the river is near the place where the provinces of Rieti, Teramo, and L'Aquila meet.
