Three excavations were undertaken of ancient roads that were affected by the modern road network. Along the present via Vallerano, corresponding to an ancient road that left the town to the south and led towards the sanctuary of Fondo Ruozzo, several tracts of basalt paving were recovered. They were at noticeably different heights which rose towards the west.

In the locality of S. Lieno, along the ancient road ad Suessam, trenches were dug in correspondence with the ancient bridge. In a hole in the paving a series of make ups were revealed which contained pottery fragments, coins and metalworking waste which dated the layers to the end of the 1st-beginning of the 2nd century A.D.
