The tunnel extends in the Altona planning section north of Behringstraße/Walderseestraße to north of Holstenkamp/Schulgartenstraße at the location of the “Schießplatz”. It reduces noise for sensitive zones in this area. At the same time, the connection between the eastern and western areas of the districts of Othmarschen and Bahrenfeld will be restored. The construction of the approximately 2,230-meter-long tunnel is intended to achieve the following objectives, among others:
The tunnel has a height of 5.15 meters. There is sufficient space for built-in components such as lighting, tunnel radio, loudspeaker systems etc. There are niches in the tunnel ceiling for permanent light signs and signposts. Thus, as in the tunnels Schnelsen and Stellingen, height control is not necessary.
A recreation park and allotment gardens are to be created on the tunnel later. For this purpose, the tunnel will be covered with a 1.20 meter thick layer of rootable soil.
The streets Bahrenfelder Chaussee and Osdorfer Weg, crossing the A 7, will pass over the tunnel structure. The Baurstraße and the Kielkamp, however, are not. They end in the tunnel area, equipped with turning facilities. Road users in Kielkamp will also be able to use the Holstenkamp in the future. As a new, two-strip main access route, it will connect the intersection Schnackenburgallee/Holstenkamp via the Altona cover with the so-called Ebertplatz.
The HH-Bahrenfeld junction will in future be located in the tunnel area, so that the access and exit ramps will also be completely enclosed. The access ramp towards Flensburg at the AS HH-Othmarschen junction will also be located in the tunnel. In addition, a pedestrian bridge over the Osdorfer Weg is planned to provide a continuous path on the green corridor of the tunnel cover.
In the project A7 Tunnel Altona, the decision was made to use the internet-based project platform EPLASS CDE. EPLASS CDE’s drawing management and document management are utilised here. All processes are presented transparently and automatically and the project participants can access and edit all data at any time and from any place. This means that all correspondence, drawing documents, statics, inspection reports and claims are organised, approved and archived via EPLASS CDE.
