At the tip of southern Italy, along an old highway that winds through the mountains, a series of huge concrete bridges will eventually be turned into vertically stacked neighborhoods.

“The government was asking for a sustainable way to preserve the bridges”, says Manal Rachdi of Oxo Architecture, who worked on the design with Samuel Nageotte, Philippe Rizzotti, and Tanguy Vermet.

“The bridges were so beautiful, and their position was so strategic, that we wanted to turn them into housing”.

Each apartment or office will be set into a space between the existing bridge structure, so from a distance, the form of the bridge will look the same.
