The project constitutes an important part of the European TEN-T program for sustainable transport, which aims to transfer 50% of the currently road freight traffic to iron by 2050, triple the high-speed rail network and connect the main sea ports to the railways and reduce emissions from transport by 60%.

The Naples-Bari HS / HC line will allow trains to travel at maximun speed of 250 km/h through numerous internal territories to connect communities and economies at risk of depopulation, reducing travel times from Puglia to Campania, Lazio and the rest of the center northern Italy and vice versa.

The Webuild Group is involved in the construction of four sections of the line: ANapoli-Cancello, pice-Hirpinia, Hirpinia-Orsara and Orsara-Bovino.

The Naples-Cancello section will run for 15.5 kilometres between Naples and Cancello. It will bring rail service to the Napoli Afragola station. The project also includes the construction of the Acerra and Casalnuovo Stations and the urban station Centro Commerciale. 

The Apice-Hirpinia section will run for some 18.7 kilometres between the towns of Avellino and Benevento and includes the construction of a station at Hirpinia and a stop at Apice, three tunnels and four viaducts.
 

The Hirpinia-Orsara section envisages the construction of 28 kilometers of line, almost all of which (27 kilometres) built underground. A work of great excellence that will allow trains to reach 250 km/h.

The Orsara-Bovino section envisages the construction of 11.8 kilometres of line and will support trains travelling at speeds ranging between 200 and 250 kilometres per hour. The project will double the capacity of the existing single-rail train service along this section, passing for the most part through a tunnel of about 9.9 kilometres in length.
