Motorists traveling through the Hamburg region must prepare for significant traffic disruptions starting this evening. The A7 motorway will be completely closed for essential construction work, specifically affecting the Elbtunnel and the section between the Hamburg-Stellingen and Hamburg-Heimfeld junctions.
Closure Schedule and Immediate Impact
The full closure of the A7 begins tonight at 22:00 and will remain in effect until Monday morning at 05:00. Certain junctions will see closures starting even earlier, at 21:00, including Hamburg-Volkspark, -Bahrenfeld, -Othmarschen, -Waltershof, -Hausbruch, and -Heimfeld.
Diversion Routes for Travelers
Traffic will be routed on a large scale around Hamburg using the A1, A21, and B205. For those traveling from the south, the diversion begins at the Horster Dreieck, leading to the A1 toward the Bargteheide motorway junction, continuing on the A21 to Wahlstedt, and returning to the A7 via the B205 at the Neumünster-Süd entrance.
The Autobahn GmbH Nord has indicated that this large-scale diversion will be clearly marked via LED signage. Those intending to enter Hamburg from the south are advised to leave the A7 at Hamburg-Heimfeld and use the B75 and A255 via the Elbbrücken.
For travelers coming from the north, the most efficient route into the city is the airport bypass via the B432, B433, and Alsterkrugchaussee.
Technical Necessity and Broader Context
According to the Autobahn GmbH Nord, the full closure is required to facilitate the construction of a fresh tunnel control center and a necessary update to the traffic computer within the Elbtunnel.
These works are part of a larger initiative to expand the A7 in Hamburg to eight lanes. Currently, the A7 at the Horster Dreieck is already a bottleneck, with only one lane available for city-bound traffic until July. Which means northbound drivers may encounter two separate congestion points on their route.
Upcoming Closures and Future Outlook
Further disruptions are expected throughout the year. From 06:00 on May 9 until 19:00 on May 10—coinciding with the Hafengeburtstag—the southbound lanes between Hamburg-Stellingen and -Heimfeld will be closed, while northbound lanes remain open.
Additional 55-hour full closures are scheduled for the following periods:
- June 12 to 15: Focused on works for the Altona cover.
- June 26 to 29: Integration of the Tunnel Schnelsen control center (Elbtunnel remains open).
- September 11 to 14: Works on the Altona cover and tunnel control center.
- September 25 to 28: Work on the K20 overpass.
the road between the Horster Dreieck and Thieshope heading toward Hannover may undergo fundamental renovation until November. Ongoing construction continues to impact the region’s flow.
