At Qualiano, work for the construction of a sewer provided the occasion for the investigation of a stretch of the ancient Roman Campanian Consular road.

It was possible to reconstruct the various events and transformations undergone by the road during its long use. The road was constituted by two carriageways, on a north-south alignment, with an overall width of 7.00 m, which although contiguous, differed in chronology and construction technique, one having a paved surface the other a beaten-earth surface. The first, of which the make up layers were also investigated, began to be abandoned from the 2nd century A.D. onwards. The other, situated to the west, consisted of a beaten surface of sand and pozzolana circa 3.00 m wide. It also presented wheel ruts and, as it was at the same height as the contiguous glareata, must have been used for a certain period as a second carriageway, reserved for lighter and faster loads. It later became an alternative to the basalt carriageway that was under reconstruction.

Not far from this find, and probably to be placed in relation to the via Campana, a well was found with related conduit in the form of a cuniculus excavated in the earth. This was discovered in the central square of Qualiano, an area which the ancient consular road crossed from south-east to north-west. Amongst the abundant material found in the fill, which dates the obliteration to the 2nd century A.D. was a beautiful, almost intact, Italian sigillata cup.
