Overview
- Autobahn GmbH now expects completion of the overhaul between Spanische Allee, the Zehlendorf interchange and the state border in the second quarter of 2027.
- An unexpectedly large volume of unexploded ordnance uncovered during construction is the primary driver of the schedule extension.
- Previously unknown water pipelines discovered in an adjacent nature reserve must be rerouted within a designated water-protection zone, adding safety and environmental measures.
- Officials are coordinating an updated timetable and have not released revised costs, with the last public estimate at about €32 million.
- Commuters face prolonged congestion between Berlin and Brandenburg as roughly 82,000 square meters of the largely 1960s-built corridor undergo their first full renewal.
