Webuild has started construction on four work sites in southern Italy, two between Campania and Puglia and two in Sicily. The works are underway for the construction of 83 kilometres of new railway lines, with an overall value of more than 3 billion euro. These are the remaining two construction sites of the Naples-Bari high-speed line, the Hirpinia-Orsara and Orsara-Bovino sections, 40 kilometres of line, and the construction sites for the first two functional lots of the Messina-Catania, Fiumefreddo-Taormina/Letojanni and Giampilieri-Taormina sections, for a total of 43 kilometres of line. The works are part of the 27 major infrastructure projects currently under construction by Webuild. The consortiums awarded the works by Rete Ferroviaria Italia (Gruppo FS Italiane) in 2021, both led by Webuild with a 70% share together with Impresa Pizzarotti with a 30% share, can now start construction after approval of the executive design.The Hirpinia-Orsara section consists in 28 kilometres of line of which 27 kilometres will be in tunnels whilst the Orsara-Bovino section consists in the excavation of a twin-tube railway tunnel of about 10 kilometres and an additional 2km of line. The two contracts are part of the broader project to upgrade the Naples-Benevento-Foggia-Bari railway axis, which envisages doubling single-track sections and constructing variants to the existing route to improve the integration of the south-eastern railway system with the high-speed network. On the same route, Webuild is also building the Naples-Cancello section, 15.5 kilometres of track in the vicinity of the Naples-Afragola high-speed station, and the Apice-Hirpinia section, 18 kilometres of line to cross the Apennines.The Taormina-Giampilieri section consists in 28.3 kilometres of line, including 25.2 kilometres in tunnels to be built with mechanised excavation using 3 TBMs (Tunnel Boring Machines), 7 viaducts and 2 railway stations. The Fiumefreddo-Taormina/Letojanni section stretches for 15 kilometres and includes the Taormina-Letojanni interconnection, the Taormina underground station, four tunnels and two viaducts. The two sections are part of the Palermo-Catania-Messina railway upgrading project, which aims to speed up the island's rail connections and improve the accessibility of the region. On the Palermo-Catania line, the Webuild Group is already building the Bicocca-Catenanuova section, which will help trains travel between the two Sicilian cities at a maximum speed of 200 kilometres per hour.
