Map with all coordinates: The Billwerder-Moorfleet tunnel is a road tunnel in the course of the federal motorway 1 under the Berlin – Hamburg railway line and the Hamburg-Billwerder transshipment station .
history
When the south-east connection Hamburg between the sections Hamburg– Lübeck and Hamburg– Hanover / Bremen , which was built from 1960 to 1963, the railway line between Hamburg and Bergedorf had to be crossed. The low traffic on the railway line due to the division of Germany made the work easier. First half of the then 32 tracks were removed in order to build an overpass, then the other half.
Building
The tunnel consists of two independently constructed structures. The upper structure is the overpass of the railway in the form of a girder bridge . It consists of a reinforced concrete slab with two fields on the side abutments and a central support. Below are the two troughs for the motorway with a clear width of 15.5 meters each. The troughs have no direct connection to the structure of the railway overpass, so the troughs had to be secured against buoyancy with sand ballast as they are around seven meters deep in the groundwater.
The tunnel has a length of 243 meters, plus preparatory work for a possible enlargement of the transshipment station and thus an extension of the tunnel on the south side by 98 meters. The tunnel system is 735 meters long, including the access ramps. The motorway runs through the two tunnel tubes with three lanes each.
