First Tube of Altona A7 Noise Barrier Tunnel Nears Completion
Hamburg, July 2, 2026 – The construction of the first tube of the A7 noise barrier tunnel in Hamburg-Altona, heading south, is nearing completion, bringing the promise of an end to highway noise in the area closer to reality. The final section of the 2.3-kilometer tunnel, approximately the size of a tennis court, is expected to be concreted by Friday, marking the completion of the first tube between Volkspark and the Elbe.
For Transport Senator Anjes Tjarks (Greens), this is a significant milestone. “When the tunnel is passable – which will be in the second half of next year – then there will be no more traffic noise from the A7 in western Hamburg,” Tjarks stated. Once operational, the existing lanes, currently exposed, will be rerouted into the tunnel.
Extensive Technical Installations Still Required
Christian Merl from Autobahn GmbH highlighted that significant work remains on the raw structure. “All the technology we need must be installed there. This includes operational and traffic technology, as well as all safety-related facilities, so that we can even put the tunnel into operation.” This phase will involve laying an additional 2,500 kilometers of cables.
Second Tube and Green Corridor Planned
Following the completion of the first tube, construction will commence on the second tube, heading north, which is scheduled for completion in 2029. By the early 2030s, a continuous green corridor is envisioned to stretch from Volkspark to the Elbe on the tunnel’s roof.
The project, which includes the greening of the Altona Autobahn lid, is estimated to cost over 100 million euros. Despite the tunnel being slated for completion in three years, the park itself is not expected to be finished for another eleven years.
Urban Development Opportunities
The A7 tunnel project also presents new opportunities for urban development. Hamburg plans to utilize the plots adjacent to the Altona Autobahn lid for housing and the Science City Bahrenfeld. This strategic use of land underscores the long-term vision for the area’s development.
Earlier, a similar project saw the opening of a park on the A7 Autobahn lid in Stellingen, transforming a former highway area into meadows, playgrounds, and allotments, thereby reconnecting previously separated parts of Stellingen.
This topic was discussed in the Senate today. The ongoing developments are part of a broader effort to enhance urban living quality and connectivity in Hamburg.
