Zurich main train station, cross-city link lot 3.1 - underpass south section

The centrepiece of the cross-city link between Zurich-Oerlikon and Zurich-Altstetten currently under construction is the new underground Löwenstrasse train station with 4 tracks at a depth of 16 metres. Trains in the direction of Oerlikon leave the station on two tracks. These tracks first go under the historically protected sandstone building of the southern section before they joined up with the Weinberg tunnel in the direction of the Limmat. Lot 3.1 contains the mined underpass of the southern section and the creation of a construction shaft in front of the southern section that serves, among other things, as the target shaft for the tunnel drilling machine from the Weinberg tunnel. As a sub-contractor to Arge Tunnel Weinberg, Implenia carried out all foundation engineering work in lot 3.1.
