The years-long renovation of the Königshainer Berge tunnel has come to an end: the last closure in the direction of Dresden has also been lifted as of Friday, 10 p.m., as announced by Autobahn GmbH. No further delays are expected. The A4 tunnel had been closed since Tuesday due to dismantling work following extensive refurbishment.
Refurbishment since March 2024
The refurbishment work in the tunnel began in March 2024, during which time traffic was routed through one of the two tunnel tubes. The work took place in the other tunnel tube.
Safety requirements have increased since the tunnel was completed in 1999. Among other things, new emergency call cabins have been installed and more sensors for early fire detection have been fitted to bring the tunnel up to the latest state of the art.
Germany's fourth-longest highway tunnel
According to Autobahn GmbH, 30,000 vehicles pass through the Königshainer Berge tunnel every day, 40 percent of which are heavy goods vehicles. At around 3.3 kilometers in length, it is the fourth longest freeway tunnel in Germany. Between the Nieder Seifersdorf and Kodersdorf junctions, it passes under a nature reserve.
