Overview
- The BVG began exploratory boreholes on Wednesday to take up to five-metre soil samples that will inform technical feasibility and alignment decisions for the U8 northern extension.
- The Berlin Senate issued the formal planning order in April, which assigned BVG Projektgesellschaft to carry out the next planning phases for the project.
- Planners are currently favouring a roughly three-kilometre route from Bahnhof Wittenau to Senftenberger Ring with three new stations near Märkisches Zentrum, Treuenbrietzener/Dannenwalder Weg and Wesendorfer Straße.
- BVG expects a preliminary design and updated cost estimate by mid-2027, a possible building permit around 2030 and roughly ten years of construction that would put passenger service in the early 2040s; a €560 million figure is cited in the transport plan with three-quarters federal funding.
- Environmental group BUND and some Greens argue a tram extension would be faster and cheaper, while officials note the U-Bahn would give about 38,000 residents direct subway access and that borehole results could change route, cost and schedule choices.
