Grumbach Valley Bridge gap closure successfully completed

The steel assembly of the Grumbach Valley Bridge near Sankt Ingbert was successfully completed with the lifting of the last two sections of substructure 1.

The two box girder strands of the substructure comprise a total steel tonnage of approx. 2,400 tonnes. The last two sections were lifted into place from a crane position behind the abutment on the Saarbrücken side of the bridge structure. Using a 750 tonne crane, the two sections were lifted off the heavy-duty transporters, turned and then lifted into their final position. This created the conditions for concreting the carriageway slab. Donges SteelTec has thus once again demonstrated its capabilities in the construction of large bridges.
