Lot H41 Gola del Sill-Pfons is one of the biggest sections of the Brenner Base Tunnel. The project will become the world’s longest one for the railway at 64 kilometers. Connecting Italy and Austria under the Alps once completed will become part of the Scandinavian-Mediterranean Corridor of the Trans-European Transport Network (TEN-T). Commissioned by BBT SE, the entity that is overseeing the project, the lot is being built by Webuild and its Swiss subsidiary CSC Costruzioni (50% stake) with joint-venture partner Implenia (50% stake).
The Gola del Sill-Pfons lot, which will create up to 400 direct jobs and more than 1,000 for third parties, involves the construction of the railway from Gola del Sill near the city of Innsbruck in the north to the town of Pfons further south. Among the most challenging engineering projects in the world, it includes a total of 22.5 kilometers of the two main parallel tunnels, with 38 cross passages. It also involves the creation of an underground emergency stop at Innsbruck, access tunnels, exploratory tunnels, and parts of other secondary tunnels. There will also be the construction of a bridge over the Brennero A13 highway.
Webuild is already working on other lots of the Brenner Base Tunnel, including the Isarco River Underpass and Mules 2-3 in Italy after having completed Tulfes-Pfons in Austria. It is also building the railway between Fortezza and Ponte Gardena south of the tunnel.
