Under the canal

Subway extension in Nuremberg


In Nuremberg, construction work on the new U3 line is in full swing: To give Südstadt a better connection to local public transport, the existing U3 subway network has been extended since 2020.

The consortium consisting of HOCHTIEF and the Max Bögl Group is in charge of this project. The major contract includes the construction of two stations in Gebersdorf and Kleinreuth, a reversing facility and a depot in Gebersdorf. The associated tunnels are being built using both cut-and-cover and mining methods. The biggest challenge for everyone involved is the tunnel under the Main-Danube Canal between Kleinreuth and Gebersdorf.

Until 2023, 7,500 tons of concrete steel from SÜLZLE Stahlpartner in Dessau-Roßlau, supported by the subsidiaries in Pressath, Nordhausen and Ehrenfriedersdorf, will provide the necessary stability. In addition, 1,030 tons of list mats from SOTRALENTZ CONSTRUCTION will be installed. The laying work will be carried out by SÜLZLE Armierungstechnik. The new line, which is around two kilometers long, is expected to be commissioned in 2025.
