en.Wedoany.com Reported - The Castagnola-Vallemme section of the Terzo Valico dei Giovi project has been declared complete, marking the finish of one of the most geologically challenging segments of the entire undertaking. The partition wall for the second track heading north has been fully demolished. The section was built for Rete Ferroviaria Italiana (RFI) by the general contractor led by Webuild, with support from FS Engineering, under the supervision of Government Special Commissioner Calogero Mauceri.
From a geographical and geometrical perspective, each track in this section is approximately 2.8 kilometers long, located in the heart of the Ligurian Apennines. It connects the Vallemme construction site in the municipality of Voltaggio underground to the Castagnola site in the municipality of Fraconalto, both within the Province of Alessandria.
Faced with rock pressure and rock mass responses typical of the Apennines, as well as safety risks posed by underground natural gas, the engineering team employed high-level engineering methods and strict operational procedures. To address the technical and organizational complexity, operations in this segment were carried out simultaneously on four parallel excavation fronts, ensuring the continuity of the excavation cycle.
With the completion of the partition wall in this section, the total excavated length for the Terzo Valico dei Giovi has exceeded 83 kilometers, representing 96% of the total line length (approximately 86.9 kilometers).
The Terzo Valico dei Giovi – Genoa Junction unified project is part of the Rhine-Alpine Corridor of the European Transport Network (TEN-T) and is considered a strategic project for strengthening the logistical connections between the Ligurian port system, Northern Italy, and Central Europe. Once operational, the travel time from Genoa to Milan will be reduced to about one hour, enhancing network capacity and railway transport reliability, particularly benefiting freight transport.
On the occasion of the partition wall demolition, Government Special Commissioner Calogero Mauceri, the Piedmont Region's Commissioner for Strategic Infrastructure Enrico Bussalino, and the President of the Province of Alessandria Luigi Benzi attended the event at the Vallemme site. Italy's Minister of Infrastructure and Transport, Matteo Salvini, expressed satisfaction with the progress of the works, emphasizing the project's strategic value for Genoa, Liguria, Piedmont, and the national logistics system, and noted that overcoming the geological operational difficulties gives this milestone special significance.
