While the construction of Museumsinsel Station is being finished we already face new tasks like the restoration of the "Waisentunnel" between the U5 and the U8 or a new training center for BVG at Olympiastadion Station.
Museumsinsel Station will be finished in summer 2021. The exact date will be announced in good time.
Depending on the Corona situation in summer, there will be a party or not.
The U5 gap closure extends Berlin’s U5 underground line from Alexanderplatz to Brandenburger Tor and connects it there with the already completed U55. The U5 and U55 merged to form one line: the new U5, which runs from Hönow to Hauptbahnhof.
Since 2013, we have a budget of 525 million. The project is funded by federal and state funds.
The new line section is 2.2 kilometres long. It runs from Alexanderplatz past Berlin City Hall. Then it crosses under the Marx-Engels-Forum, the Humboldt Forum, the Spree and the Spree canal, before wending its way below the Unter den Linden boulevard to Brandenburger Tor underground station. On connection with the U55 section, 1.5 kilometres long, and the 18.3 kilometres of the present U5, the new U5 from Hönow to Hauptbahnhof will have a length of 22 kilometres.
The U5 gap closure will create three new underground stations:
Underground station Rotes Rathaus is located directly in front of City Hall, below Rathausstraße.
Underground station Museumsinsel extends south of the Palace Bridge beneath the Spree canal.
Underground station Unter den Linden is a new interchange for the U5 and U6 and located under the junction of Unter den Linden and Friedrichstraße.
Most of the tunnel for the U5 gap closure – from Marx-Engels-Forum to Brandenburger Tor station – was built using the shield tunnelling method. Tunnel boring machines are in principle rolling factories that move through the subsoil and, in addition to boring, also create the tunnel carcass. The machine we were using was specially designed and configured for this particular construction project. It will excavate two separate main tunnels through the finished station pits.
The closure of the gap between the U5 and U55 will create a direct connection between the eastern parts of the city, the historic centre, the government district and the Central Station. In addition to the direct link with Bundestag and Brandenburger Tor stations, the Central Station will also be connected to the entire Berlin underground network. Passengers will finally be able to change directly from line U5 to the U6 and the north/south S-Bahn. The new connection also relieves the strain on the S-Bahn and the U2 on weekday commutes.
The BVG AöR as a building owner erected the new route on contract of the Berlin Senate with federal and state funds. The BVG Projekt GmbH was founded in 2014 to take over project management.
The symbolic ground-breaking ceremony for construction of the U5 gap closure was held in April 2010. Construction works started in 2012. The new U5, Rotes Rathaus Station and Unter den Linden Station went into operation on December 4th, 2020. The opening of Museumsinsel Station is expected for summer 2021.
