Museumsinsel is a subway station under construction in Berlin's Mitte district. It is part of the extension of the subway line from Alexanderplatz to Brandenburger Tor, with their construction in 2010 (the first cut of the spade) was started. Both should be opened simultaneously in 2020.

A station with a central platform is being built at the eastern end of Unter den Linden, between Zeughaus and Berlin Palace. Part of the station will be located just south of the Schlossbrücke under the Spree. The platform will be located at a depth of 16 meters below the upper edge of the street.

At both ends, access structures are erected with a distribution level below the road surface. On the west side, access points are created in front of the Kronprinzenpalais and east of the Zeughaus in the direction of the Museumsinsel. On the east side of the station two entrances will be created directly at the Humboldtforum. Both access structures will be equipped with escalators, and the east entrance will also receive an elevator leading from the surface to the platform.

First, the two excavations for the later access structures are made, in the east in open construction and in the west in cover construction, each in the protection of slurry walls and an HDI sole. Since the excavation pit is partly located in the Spree, it must be partially filled during the construction period behind a cofferdam to be created. The station area will be built only after passage of the tunnel boring machine and production of the two track tunnels. This is done, in contrast to the other stations of the new section, starting from the two excavations in mining propulsion under cover of a ground freezing. The icing process was already used in the construction of the Brandenburger Tor station.
