Excavation work has begun on the main tunnel for BBT construction lot H41 Sill Gorge-Pfons, in Ahrental near Innsbruck. The Austrian Federal Minister Leonore Gewessler the patroness was present.   The ceremony was attended by numerous stakeholders of the BBT project, including the governor of Land Tyrol Günther Platter, the governor of the Autonomous Province of Bolzano Arno Kompatscher, the President of the Province of Verona Manuel Scalzotto, the CEO of ÖBB Infrastruktur AG Judith Engel and the Italian member of the Board of Management of BBT SE Gilberto Cardola.   

In total, approx. 22.5 km of main tunnel tubes and 38 cross passages with a total length of approx. 2.3 km will be excavated in this construction lot. In order to ensure the fastest progress possible, the H41 Sill Gorge-Pfons lot was extended southwards by three kilometres, where it meets construction lot H53 Pfons-Brenner. The entire excavation of the exploratory tunnel in H41 has already been completed in a previous lot, so the geological conditions in this stretch are very well known.  

Since mid-January 2022, the bidding consortium H41 Sillschlucht-Pfons, which consists of the companies Implenia Österreich GmbH, Implenia Schweiz AG, Webuild S.p.A and CSC costruzioni sa, has been carrying out the works on this lot. The works are expected to last until summer of 2028; the total bid amount offered by the bidding consortium is EUR651 million. ARGE H41 decided to build the necessary precast concrete elements for the tunnel lining directly on the construction site, saving about 27,000 truck journeys on the highway.
