Preparatory work on the new sections is already underway, and construction is expected to take six years to complete. 

This deal follows the award of a €500m contract in December 2020 for Lot A of Line U2 to a 50:50 consortium of Strabag and Porr, which covers the construction of 7km of tunnels and four new stations. 

The contract is part of the €1bn Phase 1 of the U2xU5 project to split Line U2 to create a longer line and a new Line U5, which broke ground in October 2018.  

The project is funded by the Austrian federal government, the City of Vienna and Wiener Linien, with a total projected cost of €2.1 bn. 

The project includes boring a new tunnel between Matzleinsdorferplatz and Rathaus, where new platforms for Line U2 will be built underneath the current U2 platforms.

The Rathaus - Karlsplatz section of the existing Line U2 will be transferred to the new Line U5, which will be extended north from Rathause to Frankhplatz from 2024, and to Elterleinplatz from 2026. Line U5 will become the first fully automatic metro line in Vienna. 

Line U2 will then be extended south to Matzleinsdorferplatz from 2026, and to Wienerberg from 2028.
