The shell of underground station unter den Linden is in the final phase. In summer 2017 the expansion will begin.

On the U5 level of the future crossroads the production of the sole is completed. On the intermediate level, which later serves as a distribution area, the future operating areas will be produced as part of masonry work. At the U6 level, residual work is performed without affecting the passage of the U6.

Before the removal of the subway station can start, the existing pillars must be replaced by the round pillars. The stiffening tubes can also be removed then.
