The Tiergarten Tunnel will be closed at night for two weeks - there is a risk of traffic jams!
Starting on November 19, 2025 Tiergarten tunnel comprehensive maintenance and repair work in Berlin. This work will take place over a period of two weeks and is designed to ensure the operational and traffic safety of the tunnel. The focus will not only be on maintenance, but also on checking and optimizing the technical facilities.
The construction work is leading to significant traffic restrictions. The north and south lanes of the Reichpietschufer to Heidestraße entrances and exits will be completely closed. The closing times are set in such a way that they cause as little disruption to daytime traffic as possible: from8:30 p.m. to 5:00 a.mon the nights of September 15th to 19th and September 22nd to 26th, 2025.
Cause of additional closures
In addition to the planned maintenance work, there have been unexpected traffic closures in recent days. Last Wednesday, the Tiergarten Tunnel was again closed to traffic in both directions. The reason for this was sick employees, which led to long traffic jams rbb24 reported. Transport Senator Ute Bonde (CDU) expects further closures until the weekend.
As it turned out, a change in responsibility for tunnel monitoring from the federal highway company to the state of Berlin is to blame for the problems. This transition phase is beginning to have negative effects, as Berlin has already taken over some of the monitoring tasks while at the same time suffering from a staff shortage. A total of six positions are planned for tunnel monitoring, one of which is currently vacant, two new employees have not yet been sufficiently trained and three are absent due to illness.
Human resources problems in the public sector
The difficulties with personnel in the area of tunnel monitoring are not isolated. A rising average age of employees in the public sector and an impending wave of retirements are further aggravating the situation. A current book highlights that the shortage of qualified personnel to monitor tunnels and other public facilities could become a serious risk in the context of tight budgets and a shrinking talent pool.
Monitoring of tunnels longer than 400 meters is mandatory in order to be able to act quickly in the event of traffic jams or accidents. Monitoring of the Tiergarten Tunnel is coordinated at the Berlin tunnel control center in Tempelhof. Until 2021, there was a central tunnel control center for all road tunnels in Berlin, but this no longer exists. The Senate is working intensively on solving the existing personnel problems in order to prevent future bottlenecks.
