The construction of the Pfons-Brenner section (lot H53) will take around six years. The scope of the contract includes two single-track main tunnel tubes with a total length of 25.2km. The PORR – MARTI consortium will use two TBMs as well as drill and blast. The TBMs have an excavation diameter of 10.37m, allowing them to cover a distance of up to 30m per day. In addition to the main tunnels, another 3.6km of exploratory and cross-cut tunnels are planned.

“We are delighted to be tackling this project of the century with our partner MARTI”, said PORR CEO Karl-Heinz Strauss. “The Brenner Base Tunnel is a key response to the core issue of mobility that Europe needs to address”.

Strauss adds: “We have reorganised our team and will now complete this section quickly. As a link between Austria and Italy, the Brenner Base Tunnel needs to play its key part in the European transport network as soon as possible”.

The new contract is not PORR’s only construction lot for the Brenner Base Tunnel: The company is also building the approximately 600m long link between the tunnel and Innsbruck’s main railway station through the Sill Gorge with construction lot H21. Completion of the Sill Gorge section is planned for 2024.

The BBT consists of two tubes running 40-70m apart for 64km between Tulfes/Innsbruck and Fortezza, making it the longest underground railway stretch in the world.
