Deutsche Welle area Contaminated street closed off

Bonn · Kurt-Schumacher-Straße in front of the Deutsche Welle building has been closed off due to contaminants discovered in the asphalt. Workers should have the road ready again in time for World Climate Conference preparations.

Following the discovery on Friedrich-Ebert-Allee (B 9) a week ago, workers have now found contaminants in the asphalt on Kurt-Schumacher-Straße in front of the Deutsche Welle building. It means for the residents in the area that they will only be able to access their homes on foot for the next two weeks while the affected road surface is being removed.

Kurt-Schumacher-Straße is already closed to thru traffic between Heussallee and Deutsche Welle. This will also apply to residents from August 14 to August 25. The underground parking garages of Deutsche Welle and Deutsche Post will remain open from the Charles-de-Gaulle-Straße entrance despite the road works.

City engineering officials say the work needs to be completed now so it is finished by the beginning of October when preparations for the World Climate Conference will kick into gear. Areas surrounding the World Conference Center Bonn (WCCB) will be involved and that street will need to be open by then. By working on the entire surface at one time, the work can proceed more quickly.

The contaminant was found by workers while removing the road surface. It was identified as Polycyclic Aromatic Hydrocarbons (PAH), previously used in tar but prohibited since the 1970’s. Today, bitumen is used instead. PAH was also found on the B 9 road surface, causing delays there. A higher concentration of the contaminant was found on Kurt-Schumacher-Straße and on Dahlmannstraße than initially determined.

But that’s not the only obstacle for construction workers; they have to create search slots to determine exactly where various lines are running as these will be needed for the “Bundesbüdchen” when it is put up at the corner of Heussallee and Kurt-Schumacher-Straße. It is a historical snack bar and kiosk which dates back to serving the government quarters when Bonn was capital of Germany.
