Building time 2008-2011

Completed

The entire section was completed in 2012.

Special challenges

Specifically the BW20 above the trough (ARLT) was concreted from the counter-bearings by incremental launching from one side and with sectional scaffolding from the other. Concreting took place in all weathers and temperatures between -20 °C and +30 °C, always with the support of our central lab in Bernburg (Mr. Arndt). Based on the demand for cements with an Na2O-equivalent < 0.8, almost all concretes were delivered with a CEM I 42.5 n (sd).
