Berlin’s underground line 3 will be extended in the Zehlendorf district – this was decided by the Senate on 14 January 2024. The small profile line 3 will be extended by approximately 850 metres from its current terminus at Krumme Lanke to the Mexikoplatz S-Bahn station on line S1, largely underground along the Argentinische Allee. Krumme Lanke is terminus of Berlin’s network since December 1929. The new underground station will be built south of Mexikoplatz.
The Senate has commissioned Berliner Verkehrsbetriebe (BVG) to initiate further planning steps. According to transport senator Schreiner, construction could still begin in 2026 in a favourable scenario, i.e. during the current legislative period. However, it remains to be seen how realistic this is in practice. The first trains are scheduled to run in 2030/31. The line is expected to be built using the cut-and-cover method, without tunnelling machine. Mexikoplatz would be the 176th underground station in the German capital city.
The costs for the project is currently expected at 103 million euros, three quarters of which is to be funded by the federal government.
Further underground extensions are being planned – the current Berlin Senate is much more in favour of extending the metro than its predecessors.
