The bridge in masonry, called Pons Lapidis, was built in Augustan period. With its eleven dissimilar arcades it used to be 140 meters long. Today only the foundations conglomerate remains from the original construction.

Half-destroyed by floods, it was rebuilt by Teodorico in 493AD with various materials. In 1177, a great flood diverted the waters from the west Parma areas, leaving the bridge area all dry.
Some of the houses built above it, were demolished by Pier Luigi Farnese in 1547, because they obstructed the Via Emilia.
The two arcades have been brought to light again during the operations of the Piazza Ghiaia underpass construction (1966).
