Motorway A100, section 16, interchange Neukölln to exit Treptower Park

Berlin, moving again

connecting people

The city of Berlin is growing dynamically. The existing road network is reaching its limits, the traffic is slowing down and comes to a standstill in some areas. The consequences: congestion that affects the environment, society and economy. As traffic is predicted to keep increasing, a comprehensive transport management solution is urgently required.

paving the way

To relieve the problem, an extension of Berlin’s existing A100 motorway ring road shall serve as a tangential diversion of the transiting traffic. The 16th construction phase of the A100 federal motorway connects the city districts of Neukölln and Treptow-Köpenick to the existing motorway network.

The construction of a motorway with a large number of bridge, trough and tunnel structures in an urban setting has a big impact on the cityscape and the environment, and its implementation must deal sensitively with all constraints.

creating construction culture

The new roadway runs underground, which allows existing roads to stay as they are. The noise of the traffic is limited to the roadway itself and cannot spread to the adjoining areas.

A new piece of motorway with a large number of traffic structures impacts on the architecture of the cityscape. The special designs and alignment contribute to the significance and the identification of the traffic structures – taking into account dynamics and perception.

New construction of a 6-lane motorway in an urban area under continued traffic of crossing streets and railways.
The planning section has a length of approximately 3.00 km and will be cut into the ground (below ground water level) due to the surrounding urban area. The erection of the structures will take place in dry building pits (two frames method).

  • tunnel l=385 m
  • trough structures l=1,850 m
  • supporting structures
  • four road bridges
  • three railway bridges
  • noise protection surface of the trough structures
  • noise protection walls
