The excavation for the new underground station Bonner Wall in the south of
Cologne, seen from the northern end on 18 March 2006. On the right in the
background the pit extends to a ramp leading to the end station
Marktstraße, which is located on the surface. On the left, where the
sheet pile wall is visible, another ramp towards the bank of the Rhine will be
built. Trams of line 16 will use it to reach the old course of the Rheinuferbahn
north of the stop Schönhauserstraße, while those of lines 5 and 17
will travel to the Marktstraße. This excavation also is the starting pit
for the two tunnel drilling machines, which will drill two tubes (one for each
track) from here to a place near the main station. Most of the excavation is
covered to allow the surface traffic to flow unobstructedly (more or less). The
startup of the new underground line is planned for 2010.
