Overview
- The A1 will be fully closed between Vechta and Cloppenburg from 04:00 on 10 October until 05:00 on 12 October to install four new bridge structures over the motorway.
- Autobahn GmbH has set official detours for the Vechta–Cloppenburg closure that send traffic toward Bremen via U13 and toward Dortmund via U52, with longer alternatives using the A29, B213, B68, B218 and B214.
- A separate full closure of the A1 between Dreieck Norderelbe and Kreuz Hamburg‑Ost will run from Friday 21:00 until Monday 05:00 and will divert overregional traffic via the A7 through the Elbtunnel and on to the B206/A20 to rejoin the A1 at Kreuz Lübeck.
- Officials plan heavy‑truck test runs and sensor calibration on the Norderelbbrücke during the Hamburg closure, and traffic authorities warn of severe congestion because autumn school holidays begin and inner‑city access is limited by a recent water‑main break and a reduced S‑bahn work window.
- The Vechta work follows demolition of the old bridge structures in November 2025 and is part of a staged replacement program that Autobahn GmbH says should finish and open the four new bridges later this year, though the timeline remains subject to short‑notice changes.
