Overview
- The Autobahn GmbH has confirmed a 55‑hour full closure of the A7 including the Elbtunnel from Friday, 25 September to Monday, 28 September to complete remaining works.
- The shutdown is meant to finish the K20 Hochstraße Elbmarsch and carry out construction on the Altona deck so the route can run as an eight‑lane bridge.
- Authorities are advising long‑distance drivers to bypass Hamburg using the A1, A21 and B205 and say electronic signs and diversions will guide traffic away from the closed section.
- A separate incident on Wednesday, 23 September saw damage to a temporary bridge on the A643 near Wiesbaden force a partial closure and long jams before repairs reopened the section the same day.
- Regional resurfacing and ramp works such as on the A73 near Bamberg and at Autobahnkreuz München‑Süd will continue on staggered schedules, so commuters should expect overlapping restrictions and plan routes in advance.
