German railway-firm Deutsch Bahn has awarded tunnel construction contracts for the Stuttgart 21 project to a consortium led by Austrian contractor Porr worth US$1bn (£608M).
The Stuttgart 21 project will involve replacing the existing tracks and platforms of the city’s main railway station, Stuttgart Hauptbahnhof, with a completely new, mainly underground transport hub.
A total of 60km of new railway line and three new stations – Stuttgart Hauptbahnhof (Stuttgart Main Station), Bahnhof Flughafen/Messe (station at the airport/trade fair centre) and Mittnachtstrasse S-Bahn (rapid transit) station in the new Rosenstein district – will be constructed for the Stuttgart 21 project.
Porr will be constructing the 9.5km long Filderstadt tunnel which connects the new railway station with the airport and the 6km Untertürkheim tunnel.
Construction will consist of a twin-bore single track railway lines with regular cross-passages.
“We are pleased that we award this important process for the rail project now able to complete successfully,” DB infrastructure officer Volker Kefer.
”The awarding of the tunnels is another important milestone in the progress of the project. It is now clear that the cost of speculation in recent weeks have been unfounded.”
The tunnel contracts represent about one quarter of the entire project.
