On 16/04/2021 at the Libarna site, near the municipality of Arquata (AL) there was a breakthrough inside a chamber  of the Serravalle tunnel, the second longest tunnel for the Terzo Valico dei Giovi high-speed/high-capacity railway project, developed in Italy by Consorzio Collegamenti Integrati Veloci (COCIV), the consortium is led by Webuild. The milestone, which brings to 65% the amount of excavation completed, establishes an uninterrupted connection among the work sites along a 22-km section of the railway on the side of Piemonte region of the project.  

The Serravalle tunnel, about 7 km in length, was excavated for 6.4 km by TBM Giovanna, which ended its work on September 2020, while TBM Elisa came to a halt today. Both have a diametre of 10 m. The excavations faced complex situations like the path under the Serravalle Outlet and the historic Genoa-Turin railway that required the application of innovative monitoring systems above and below ground.  

The Genoa-Milan connection will reduce travel times between the two cities and represent only part of the sustainable mobility to be guaranteed by Terzo Valico dei Giovi. At a total length of 53 km, the railway will join the Rhine-Alpine corridor of the Trans-European Transport Network (TEN-T), connecting Genoa on the Mediterranean Sea with Rotterdam on the North Sea. The railway will have four connections at Voltri, Genova Parco Campasso, Novi Ligure and Tortona in order to link it to the existing lines. Webuild is also working on the Railway Juncture in Genoa, another strategic project that will bring high-speed rail service to the port.
