Earthworks and some motorway construction began at Charlottenburg-Nord on 3 July 1967, which is located at Siemensstadt. Construction began for the section to Rohrdamm from 1973. The construction work for the next section towards Spandau began in 1973. The route leads north of the station Richard-Wagner-Platz further under the Sömmeringstraße. Halfway to Mierendorffplatz, the Spree is underpassed using the caisson construction method. After a few meters, the station follows Mierendorffplatz. North of the station, the route makes a wide berth to reach the existing S-Bahn station Jungfernheide. Here, similar to the station Schloßstraße, the platforms were built on two levels. The other tracks are kept until today for a possible extension of the U5, which is to lead from Lehrter to Tegel Airport via Turmstraße and Jungfernheide. However, the plan was cancelled due to the budget situation, the longer length of the extension north of Jungfernheide station due to the planned closure of Tegel Airport. Trams will be replacing the U-Bahn extension. The finished extension is now used for firefighting exercises and is no longer usable for any future line. The extension to Rohrdamm followed on 1 October 1980, providing the district of Spandau with its first underground connection.
