A14 Elbebrücke Wittenberge

The Elbebrücke Wittenberge A14 construction project involves the building of a new road bridge over the Elbe River as part of the expansion of the BAB A14 highway from Magdeburg to Schwerin, located south of the city of Wittenberge. The new bridge is situated west of the existing B189 road bridge and spans a total length of 1,100 meters, making it the longest bridge in the entire A14 North extension.

Segmented Bridge Construction

The bridge construction is divided into two main segments: a foreland bridge and a main river bridge. The foreland bridge extends 695 meters and features 14 spans with a prestressed concrete structure, reinforced slab beam cross-section, and pile foundation. It is constructed using incremental launching equipment. The main river bridge spans 412 meters and employs a steel box girder with an orthotropic deck, which is fabricated laterally and installed using the incremental launching method. Both segments include 4-meter-high multifunctional walls on each side of the superstructure.

Project Costs and Timeline

The total project cost is estimated at 63 million euros, with construction having commenced in January 2022 and a projected completion date in October 2025. The primary contractor overseeing construction is BBV Systems, responsible for the prestressing process, while the project management is handled by Implenia Construction GmbH, NL Nordost, GS Berlin. The client for the project is DEGES Deutsche Einheit Fernstraßenplanungs- und bau GmbH.

Infrastructure and Economic Benefits

The Elbebrücke Wittenberge A14 project brings several societal benefits, primarily enhancing the infrastructure by improving the connectivity between Magdeburg and Schwerin. This improvement aims to facilitate better transportation and logistic pathways, potentially boosting local and regional economic activities. Additionally, the construction focuses on integrating modern engineering techniques and ensuring that the structure meets contemporary standards.
