Overview
- The full shutdown between Hamburg-Stellingen and Hamburg-Heimfeld runs from Friday, Feb. 20 at 22:00 to Monday, Feb. 23 around 05:00 to install sign gantries, advance the Altona noise-tunnel build and perform Elbtunnel maintenance.
- Long-distance detours route via A1–A21–B205, inner-city traffic is steered over the Elbbrücken, and the B75 near the A7 junction Hamburg-Marmstorf is reduced to one lane per direction during works.
- Authorities strongly advise avoiding Hamburg during the closure window, with further A7 full closures already scheduled in 2026.
- Berlin’s new Elsenbrücke cannot open yet because frost has halted required finishing work, and the traffic administration says no new date can be set until a sequence of frost-free days occurs.
- Elsewhere, cities roll out local restrictions: Mannheim phases alternating and full closures for BBC‑Brücke works from Feb. 16, Chemnitz announces multi-week street closures and detours starting next week, Potsdam maintains lane and street blockages, and Hamburg-Ottensen closes Hohenzollernring to cars through roughly May 8.
