In the layout of Trajan’s Warehouses, the Colonnaded Road ran perpendicularly to the Portico of Claudius. This monumental passage consisted of a double row of nine travertine columns, to a large degree conserved, which divides into three naves a space enclosed between the two masonry walls in opus mixtum (opus latericium and opus reticulatum). Topped by tuscan capitals, the columns are in large, superimposed drums, using the “rustic ashlar” or “unfinished” technique, attested in Rome in other monuments dating to the reign of Claudius. No columns are conserved in the second section of the corridor.
