Overview

• Deges and the Autobahn-Gesellschaft broke ground on the roughly €80 million replacement, targeting completion by summer 2027.
• From October 30 at 22:00 to November 3 at 05:00, the junction will see extensive closures to demolish the A100 bridge over Halenseestraße Ost, with truck detours via Schmargendorf–Spandauer Damm and via Königin‑Elisabeth‑Straße.
• The project adds a new crossing over Halenseestraße Ost and introduces continuous noise-protection walls on the side facing nearby residences.
• Parallel rebuilding of the nearby Westendbrücke is planned, with the A100 northbound section between Messedamm and Spandauer Damm expected to reopen in summer 2027.
• Traffic continues on a contraflow through the work zone and heavy goods vehicles are routed through residential areas until the new infrastructure is in place.
