Vienna’s public transport authority Wiener Linien has launched the tender process for extension of the its U2 underground metro line.
According to tender documents published in the Journal of the European Union, the project is expected to take more than seven years to complete and will be awarded to one bidder.
The project involves extension of the existing underground line U2 from Vienna City Hall (Rathaus station) and for the first section of the new U5 to Frankhplatz/Altes AKH with 11 new stations and 9km of tunnels – 6km for the U2 scheme and 3km for the U5 line.
One of the challenges on the project will be construction of tunnels at 37m below ground to take the new route under the existing U3 tunnels and construction of a new transport hub at the existing Neubaugasse station.
The City of Vienna has said that ground investigation has already been completed and results have not shown anything unexpected, which it says minimises the risk for the undeground phase.
Once completed by 2025, the new network will cut travel times from City Hall to Matzleinsdorfer Platz to six minutes.
“We aim to raise the combined modal share of public transport, cycling, and walking to 80% of all journeys made in Vienna by 2025,” said City of Vienna deputy mayor Maria Vassilakou. “The extension of U2 to the south and the new U5 provides additional incentives for switching to public transport.”
Bids for the work must be submitted by 28 September but no date has been set for the award announcement.
