The breakthrough has connected Lot H21 Sill Gorge and Lot H41 Sill Gorge-Pfons, according to a LinkedIn post from Wolfgang Holzer from BBT.
Lot H21 provides the link between the northern end of the Brenner Base Tunnel and the central station in Innsbruck.
Lot H41, undertaken by the H41 Sill Gorge-Pfons consortium comprising Implenia Österreich GmbH, Implenia Schweiz AG, Webuild, and CSC Construzioni, is located in the northern area of the BBT between the Sill Gorge of Innsbruck in the north and Pfons in the south.
Meanwhile Marti Group has reported that TBMs Wilma and Olga will be launched next week on Lot H53.
Arge H53 BBT, a consortium of Porr and Marti, will use TBM Olga to build the East Tunnel towards Innsbruck on the Pfons-Brenner section of the BBT, while TBM Wilma will dig the West Tunnel.
