Overview

• The tunnel was closed from about 6:15 a.m. until roughly 2 p.m., blocking both directions, according to the traffic information center.
• Berlin’s transport administration said a sudden staffing shortfall in the video surveillance unit forced the preventive closure.
• Police reported no accident inside the tunnel during the interruption.
• Traffic was diverted through central routes with heavy congestion on Heidestraße toward Hauptbahnhof, and several bus lines were rerouted.
• The stoppage followed last week’s multi-day northbound closure after an intoxicated truck driver damaged tunnel equipment, which officials said was unrelated to Monday’s incident.
