During Roman Age region had a long distance and high-efficiency road system, created mostly for military requirements of territorial control. The dimensions of the standard Roman roads ranged from 4 to 6 meters in width; the larger ones - which allowed the passage of two wagons - between 10 and 14 meters. The sidewalks, on the other hand, of beaten earth or paved, were between 3 and 10 meters wide. In the case of rather busy streets, these were intended for the passage of pedestrians and horses. For the construction of the ancient streets of Rome, the Romans built planks in the case of streams, or bridges - many of which are still crossed today - in the event that the road crossed a river. If the planned construction path encountered an obstacle, represented by boulders or mountainous terrain, tunnels were built, entirely dug by hand. The construction of the connections, therefore, never stopped: the Roman roads had to proceed straight, without hitches or interruptions.
Salerno could count on a system of roads that connected it to the main urban centers of the time. Via Popilia connected, on one side, with Pompeii and Neapolis and, on the other, with the interior of Lucania. Salerno also had two other roads, which put it in communication, to the N, with Abellinum and Beneventum and, to the S-E, with Paestum and Velia.
The Via ab Rhegio ad Capuam (also known as Via Popilia or Via Annia) was an important Roman road built in 132 BC (60 years after Salerno foundation). In that year the Roman judiciary decreed the construction of a road that would permanently connect Rome with the Civitas foederata Rhegium, the extreme tip of the Italian peninsula.
It is believed it was called Via Popilia, as it was ordered by the consul Publio Popilio Lenate (a strong opponent and persecutor of the Gracchi) in 132 BC. as evidenced by the pencil Pollae, a plaque in Latin, found in San Pietro di Polla (Salerno).
The road detached from the Via Appia in Capua and reached Calatia (Maddaloni), Nolam (Nola), Nuceria Alfaterna (Nocera Superiore) and Salernum (Salerno) on the Tyrrhenian Sea. From here the road headed towards the Sele plain through the town of Eburum (Eboli) It therefore appears unlikely that the route of the via Popilia passed through via Tasso, as to the west this road ends with a steep flight of steps that connects it to the sea.
Archaeological research has shown instead that, coming from Nuceria, via Popilia passed through Fratte, then under the castle of Monte Vetrano, crossed the district called 'Cupa Siglia' (= Silla encampment) and crossed two rivers, the Fuorni and the Picentino, to reach the western gate of Picentia (Pontecagnano), assumed by classical sources to be one mile (1478.50 mt.) from the port on the Picentino river.
The evidence of these roads was demonstrated by many and important towns and numerous stationes settled up on coastal territories, improved and increased with thermae during lateantique period.
After the fall of the Western Roman Empire(4 September 476) there was a spoil of the way sistem and the disappearance of some coastal towns, together with the progressive movement of people to the high sites, wich caused the shifting of the way sistem to inner country side. Coastal way sistem and ancient consolar way Reggio-Capua has been used, however, during Middle Ages, when Calabria’s territories was crossed by christian pilgrims, landed in Crotone, during their trip from Constantinople to Rome.
