The first parts of the TBM called “Lilia” were delivered to the H41 construction site for the Sill Gorge-Pfons construction lot, located south of Innsbruck. These are primarily single parts of the cutter head of the Tunnel Boring Machine. When assembled, this cutter head will measure about 10 meters in diameter.

It is going to excavate about 8.1 km of the eastern main tunnel.
