Hirpinia Tunnel along the Naples-Bari High Capacity/High Speed railway line

delayed

The Hirpinia Tunnel is part of the Naples-Bari High Capacity/High Speed railway line, a complex infrastructure project in Southern Italy. The tunnel is 27 km long out of a total 28 km functional lot and is one of the most challenging engineering works due to geological fragility and difficult terrain. The project involves tunnel boring machines (TBMs) for underground excavation and includes the production of prefabricated segments at the Roboplant 2 facility. A recent ground collapse has caused a delay in the project, requiring dismantling of TBMs and restoration work that could take about a year.
