Overview

• The Tiergartentunnel in Berlin has reopened southbound for vehicles under 3.5 tons after being closed for nearly a month.
• The closure was caused by damage to ventilation systems, which were found to be inadequate for removing smoke in case of a fire involving larger vehicles.
• Trucks and buses remain prohibited from using the tunnel, as the current ventilation system cannot support their safe passage.
• The reopening was delayed due to the time required to install new signage, as electronic displays in the tunnel were unable to reflect the updated restrictions.
• Berlin's financial constraints have hindered progress on a comprehensive repair plan for the tunnel's ventilation system, leaving the timeline for full restoration uncertain.
