The A1 will be fully closed on the night into Sunday, 8 November 2026, and again on the night into Monday, 9 November 2026, between the junctions at Bremen-Arsten and Bremen-Hemelingen from 10 pm to 5 am on each occasion. The Bremen Traffic Control Centre and the Autobahn GmbH of the federal government announced this on 7 November. The reason is scheduled work on the Weser Bridge, which requires brief full closures.
The closure applies in both directions. According to Autobahn GmbH, traffic heading towards Hamburg will be diverted from Bremen-Arsten via the signposted diversion U31 . In the opposite direction, traffic will be diverted on site. The authorities expect traffic jams and advise drivers to check the latest traffic updates before setting off, allow extra travel time or, where possible, use public transport.
The overnight full closures are part of the renovation and reinforcement work on the Weser Bridge, which has been under way since 2025. Under the construction plan, traffic is moved in phases onto the side of the bridge not currently being worked on. Further overnight closure periods are planned in the coming months so that work on the protective and supporting structures, as well as traffic diversions, can be carried out safely. The exact dates depend on progress with the work and will be announced by Autobahn GmbH.
In official minutes in 2025, the State of Bremen had already warned of lengthy restrictions and diversions, particularly for traffic heading towards Hamburg. These diversions also place a temporary burden on city access roads. The current measure, however, is limited to the two nights specified in order to minimise the impact on daytime traffic.
According to the Bremen Traffic Control Centre, two lanes in each direction will generally remain open outside the closure periods; temporary lane shifts and reduced speed limits are intended to ensure safety at the roadworks. Local media such as NDR and buten un binnen had reported the dates in advance. As of 7 November, there were no indications of any last-minute changes; if the work is postponed due to weather, the relevant authorities will announce new time slots.
Commuters and freight operators should take note: anyone travelling on the A1 in southern Bremen on the nights of 8 and 9 November should factor in the closure, use diversion U31 and check alternative routes. Navigation services will generally take the full closure into account, but do not replace the need to follow local signs.
