Traffic facilities in central Berlin
B 96 federal road
Startup Tiergarten Spreebogen tunnel (TTS)
For the central area of Germany's capital, Berlin, with its new government quarter and the newly-designed Potsdamer
Platz, a solution was needed to manage
road traffic moving in a north-south direction along the B 96 federal road.
As a result of the planning process, the
construction of a road tunnel between
Heidestraße to the north and the Landwehr canal to the south was begun in
1995. There are additional entry and exit
ramps at Invalidenstraße and Kemperplatz.
The tunnel allows through traffic to be
kept out of the government quarter and
the above-ground road that cut through
the Tiergarten park can be removed.
The tunnel is composed of three main
sections in a north-south direction:
Fully equipped tunnel
Heidestraße access ramp - Invalidenstraße access ramp
Two tunnels separated by a central wall,
each with one lane and a hard shoulder,
total width of road surface in each tunnel
6 m, plus a 1 m wide emergency footpath
on each side.
Operations buildings
There are three operations buildings to
accommodate the technical equipment;
they are all entirely below ground level.
Invalidenstraße access ramp - Kemperplatz access ramp
Two tunnels separated by a central wall,
each with one lane and a hard shoulder,
total width of road surface in each tunnel
8,5 m, plus a 1 m wide emergency footpath on each side. In the area of the main
station there is access to the German
Railways underground car park.
Kemperplatz access ramp - Reichpietschufer access ramp
Two tunnels separated by a central wall,
each with one lane and a hard shoulder,
total width of the road surface in each tunnel 6 m, plus a 1 m wide emergency footpath on each side. In this area there is access to the Sony Center and the supply
center at Potsdamer Platz (VEZ-Daimler-Chrysler).
Start of operations in the B 96 Tiergarten-tunnel
Because of delays in the construction of
the tunnel near the Lehrter station, the
tender procedure for tunnel equipment
according to the execution planning that
was current at the time was suspended in
1999.
In 2002, it appeared that the basic tunnel
structure would be completed by the end
of 2003, and because of this, the Berlin
senate administration restructured the
project leadership organization and commissioned Krebs und Kiefer to carry out
the project management for the start of
operations.

Project data
- Inner-city road tunnel
- Total length: 2,8 km
Initially, the main task was to produce revised plans that both complied with the requirements for safe road tunnels according to RABT 2003 and took into account
the existing structure, which was almost
complete.
