The intervention involves the extraordinary maintenance of the left quay of the Tiber in the section from Ponte Fabricio to Ponte Testaccio. This stretch of embankment, approximately 2 kilometers long, will undergo a special cleaning process that will also remove the river silt deposited after the river floods. Over the years, due to lack of maintenance, bushes and reeds have grown spontaneously on the layer of silt, to the extent that the original pavement of flagstones is no longer visible today. Furthermore, all scattered waste within the vegetation will be removed through separate collection, and informal settlements in the construction area will be cleared.
