On 27 August 2025, in the early afternoon, at the call of initiatives including Bass Away the A100 (A100 wegbassen), around 250 people, including local residents and environmental groups, staged a protest in front of the Estrel Hotel on Sonnenallee in Berlin - Neukolln (Berlin) during the opening ceremony of the new A100 motorway section. Protesters criticized the project's costs, increased traffic and noise, neighborhood disruption, and climate impacts, chanting against any further extension. The demonstration remained peaceful under a large police presence, while the official ceremony inside featured Federal Transport Minister Patrick Schnieder (CDU) and Berlin's Governing Mayor Kai Wegner (CDU).
