Overview

• Autobahn GmbH will fully close the A4 toward Olpe between Kreuz Köln‑West and the Eifeltor exit from Friday 22:00 until the morning of 22 September for urgent repairs.
• The works address damage at Deutsche Bahn’s Eifeltor bridge, following months of temporary speed limits, narrowed lanes and restrictions that confine trucks to the right lane.
• Long‑distance detours route traffic via the A1 toward Dortmund and the A3 to Kreuz Köln‑Ost, with officials warning of notable peak‑hour congestion on the Kölner Ring.
• Since opening the 16th section of Berlin’s A100, queues have built at the Treptow terminus by the Elsenbrücke, affecting local streets, pedestrians and BVG buses.
• Berlin traffic senator Ute Bonde acknowledged the bottleneck and said traffic lights will be adjusted to dose motorway inflows as the situation is monitored.
