Traffic Disruptions and Detours on A4 Zgorzelec–Dresden. Tunnel Closed on Wednesday, October 1

On Wednesday, October 1, 2025, drivers will face major disruptions on the A4 motorway in Saxony.

Autobahn GmbH des Bundes (Eastern Branch) has announced a complete closure of the Königshainer Berge tunnel in both directions - toward Dresden and Görlitz - due to essential maintenance work. The closure will apply to both lanes in the currently operational section with two-way traffic. It will be in effect from 07:00 until approximately 16:00.

During the closure, marked detours will be in place - from the Nieder Seifersdorf interchange (92) to the Kodersdorf interchange (93) and in the opposite direction. The Königshainer Berge tunnel is an important point along the route between Zgorzelec and Dresden, and drivers using the A4 motorway on the German side should expect significant disruptions.
