Construction work on U5: Traffic regulations from August for Berlin!

Construction work on U5: Traffic regulations from August for Berlin!

Berlin, Deutschland - On August 4, 2025, the construction work of the BVG on the U5 begins, which will last until September 21. This was announced by rbb24 . During this time, the subway traffic between the Frankfurter Allee and U-Bahn station and the Tierpark underground station will be discontinued. In order to mitigate the effects for the passengers, replacement traffic is set up by bus.

The U5 has a significant importance in the Berlin subway network, especially as an important east-west connection. The oldest section between Alexanderplatz and Friedrichsfelde was opened in 1930. The eastern part of the route, which runs between Biesdorf-Süd and Hönow, was built under high pressure about 40 years ago during the GDR era. These circumstances meant that some construction defects were not carried out professionally, which shortened the useful life of the systems. Der älteste Abschnitt ist nun rund 95 Jahre alt.

replacement and pendulum traffic

The construction work is particularly affected by the construction work. There will be a reduced operation between Tierpark and Biesdorf-Süd: Monday to Friday, the trains run every 7.5 minutes, but only every ten minutes on weekends. The original planning provided for a blocking from the end of June to the end of August, but the construction work had to be postponed due to delivery delays in the course.

Another aspect of the construction work concerns the planned track construction work between Cottbusser Platz and Kaulsdorf-Nord, which are scheduled for the period from September 22nd to September 25th. However, information about possible replacement or commuting during this time is not yet known.

background and necessity of the work

The burden for the U5 has increased in recent years because the passenger numbers are steadily increasing. This leads to increased pressure on the infrastructure. The BVG has already carried out regular maintenance and renovation measures in the past to ensure stable, safe and reliable operation. The eastern part of the U5 is largely above ground and is therefore particularly exposed to weather influences, which underlines the need for better maintenance. bvg emphasizes that the condition of the systems requires continuous and careful maintenance.
