A7 and Elbe Tunnel in Hamburg Fully Closed Until Monday Morning
Hamburg, April 18 – Drivers in the Hamburg area face significant traffic disruptions until Monday morning as the A7 motorway between the Hamburg-Stellingen and Hamburg-Heimfeld junctions is completely closed. This closure, which began on Friday evening at 10 PM, also affects the Elbe Tunnel and is scheduled to last until Monday morning at 5 AM.
The full closure of the A7 in both directions is necessary for ongoing construction work related to the new tunnel control center and an update for the traffic computer in the Elbe Tunnel, as announced by Autobahn GmbH Nord.
Extensive Detours in Place
During the closure, traffic is being extensively diverted around Hamburg via the A1, A21, and B205. For those traveling from the south, the detour begins at the Horster Dreieck, leading onto the A1 to the Bargteheide motorway junction, then onto the A21 to Wahlstedt, and finally via the B205 back to the A7 (Neumünster-Süd exit). This large-scale detour is continuously indicated by LED signage along the motorway.
Drivers heading to Hamburg from the south are advised to exit the A7 at Hamburg-Heimfeld and use the B75 and A255 over the Elbe bridges. From the north, the airport bypass via the B432, B433, and Alsterkrugchaussee is recommended to reach the city center.
Ongoing Construction and Future Closures
The A7 is currently also a bottleneck at the Horster Dreieck, where only one lane is available for traffic entering the city until July. This means drivers heading north on the A7 in Hamburg will encounter two separate traffic congestion points.
These A7 closures are part of the broader project to expand the motorway in Hamburg to eight lanes. The approximately two-kilometer-long Altona noise barrier tunnel is expected to be completed by the end of 2028. Further closures are planned, including one from May 9, 6 AM, to May 10, 7 PM, during the Hafengeburtstag weekend. During this period, the southbound carriageway between Hamburg-Stellingen and Hamburg-Heimfeld will be closed, while the northbound carriageway will remain open.
Upcoming A7 Closures in 2026
- May 9-10, 2026: A7 southbound closure (between Stellingen and Heimfeld).
- June 12-15, 2026: A7 55-hour full closure (including work on the Altona tunnel lid).
- June 26-29, 2026: A7 55-hour full closure – without Elbe Tunnel (including integration of the Schnelsen tunnel control center).
- September 11-14, 2026: A7 55-hour full closure (including work on the Altona tunnel lid, work on the tunnel control center).
- September 25-28, 2026: A7 55-hour full closure (including work on the K20 elevated road).
In addition to these closures, the carriageway towards Hanover between Horster Dreieck and Thieshope is undergoing fundamental renovation until approximately November, leading to months of impairments.
Local authorities emphasize that these measures are crucial for improving Hamburg’s infrastructure and ensuring smoother traffic flow in the long term, despite the immediate inconveniences for commuters and travelers.
