Metro Line C Extension Project in Rome

project in operation

The project involves the design and construction of the T₂ extension of Rome’s Metro Line C, covering a 4-km underground section from Piazza Venezia to Clodio/Mazzini. This includes the creation of four new stations—Chiesa Nuova, San Pietro, Ottaviano (with an interchange to Metro Line A), and Clodio/Mazzini. Two of these, Chiesa Nuova and San Pietro, will be archaeological stations designed to integrate with Rome’s historic urban fabric. The work will require complex underground engineering, including tunneling beneath the Tiber River and constructing stations as deep as 48 meters below ground. Once completed, this extension will enhance connectivity between the city centre and its northwestern districts, contributing to the full development of Metro Line C.
