A New Major Bridge over the Elbe River

Nuremberg engineering office plans new Elbe crossing near Wittenberge

The client is the federal/state project company DEGES on behalf of the federal government's Autobahn GmbH. The executing consortium is Implenia Construction GmbH, Berlin; with partners DSD Brückenbau GmbH, Berlin, Implenia Spezialtiefbau GmbH, Berlin and Stahltechnologie Niesky GmbH.

An impressive project, a very large bridge over the river on the state border between Brandenburg and Saxony-Anhalt: K+S has been involved in the execution planning of the new structure near Wittenberge since mid-2022 - the engineering office is planning the "foreland bridge" made of prestressed concrete, the substructures of the "river bridge" and all construction aids and shoring. The new, deep-foundation bridge for the A14 over the Elbe will stand next to the existing B189 bridge.

For K+S, the contract, including this Elbe bridge, means that it is now involved in the planning of three of the five major bridge construction projects currently underway in Germany.

The bridge, which is founded on piles, is not very high, but it is 1,110 meters long - 695 meters of which are part of the "foreland bridge" over the Elbe floodplains. This will be followed by the 412-metre-long section of the "Strombrücke" bridge over the river, which will be built using a completely new type of construction - an orthocomposite slab.

Around 200 bored piles are being drilled in the area of the foreshore bridge, 14 per pier axis. At an impressive 160 meters, the main span of the "river bridge" crosses the navigable river cross-section of the Elbe.

A superstructure is being built for each direction of travel for the new A14, with the first section of the first superstructure to be concreted using jacking equipment in October 2023.
