Zoo tunnel repair expenses total 150,000 euros
The Tiergarten Tunnel in Berlin, a crucial artery for traffic in the city, has reopened following extensive repairs that took place in early November 2024. The closure was necessitated by issues with the tunnel's ventilation system, specifically due to several jet fans that had to be dismantled due to excessive vibration values and material damage[1].
The repairs involved the replacement and successful commissioning of the repaired jet fans in the southbound direction of the tunnel. Once these fans were reinstalled and operational, the tunnel’s ventilation system could safely dissipate smoke in emergencies like a truck fire, restoring the fire ventilation system's operational safety[1].
The repairs, which included the dismantling and reintegration of the fans, cost approximately 150,000 euros and were covered by the state of Berlin[1]. The closure of the Tiergarten Tunnel for trucks and vans over 3.5 tonnes was lifted last week, with smaller vehicles having already been allowed since early December.
The Tiergarten Tunnel remains open to smaller cars and trucks and vans over 3.5 tonnes, ensuring the smooth flow of traffic once again. The state-of-the-art ventilation system, now fully functional, ensures the safety of all vehicles using the tunnel.
The repairs on the Tiergarten Tunnel were reported by the "Tagesspiegel" newsletter "Checkpoint", providing the public with updates on the progress of the repairs and the reopening of the tunnel[1].
In summary, the closure of the Tiergarten Tunnel was due to a failure in the ventilation system caused by damaged jet fans, leading to a loss of fire safety ventilation. The repairs, which included the replacement and reinstallation of the jet fans, have successfully restored the emergency smoke evacuation capability, allowing the complete reopening of the tunnel to all vehicles, including trucks and vans over 3.5 tonnes, in late December 2024[1].

The repairs in the Tiergarten Tunnel, a crucial artery for traffic in Berlin, were not only related to the traffic flow but also extended to the safety of finance and transportation industries. The state-of-the-art ventilation system, now fully functional, ensures the safety of all vehicles using the tunnel, thereby preventing potential financial losses due to disruptions in the transportation industry.
