Tiergarten Tunnel in Berlin: Chaos due to surprising closure!

On Monday morning, November 23, 2025, the Tiergarten Tunnel in Berlin was completely closed in both directions for safety reasons. The closure lasted around eight hours and caused significant traffic delays, particularly in Moabit, where motorists had to take alternative routes. This step was necessary due to a shortage of personnel in tunnel monitoring, which was caused by short-term sick leave. The Senate Transport Administration explained that traffic safety in the tunnel could no longer be guaranteed and that the closure had to be carried out preventively and in accordance with the rules. The tunnel was finally reopened on Monday afternoon around 2 p.m., when the late shift in the tunnel control center began work rbb24 reported.

However, on Tuesday morning the tunnel was closed again, without any specific reasons being communicated. This action followed a similar situation the previous week, when the tunnel was closed northbound due to an accident in which a truck with a drunk driver became wedged on an exit. The incident also resulted in damage to tunnel engineering, highlighting the need for safety measures. This posed challenges for the traffic information center, which then had to reroute bus routes in order to maintain local public transport t online.

Road safety and the need for preventative measures

The events surrounding the Tiergarten Tunnel are in the context of a broader traffic safety strategy in Germany. With the road safety program 2021-2030, the Federal Ministry for Digital and Transport (BMDV) is pursuing “Vision Zero”, which aims to have no deaths or serious injuries in road traffic. The BMDV provides funding to implement innovative projects to improve traffic safety, which also includes the digitalization of traffic systems. Loud Mobility Forum The BMDV offers support for initiatives to improve safety for all road users, including cyclists and motorcyclists.

Road safety issues concern not only infrastructure projects, but also the need to address existing problems, such as staff shortages in tunnel monitoring. In order to be able to react preventively in the future, it would make sense to continually optimize personnel planning in critical areas such as tunnel monitoring. This could help avoid similar delays and congestion and increase safety in urban transport systems.
