New Movable Bridge in the Antwerp port area

The Van Cauwelaert Bridge is a crucial link in the Antwerp port area on the right bank of the Scheldt. To ensure the future of this connection, the Maritieme Toegang division has entrusted the design of a new movable bridge to Sweco. This bridge will replace the current Van Cauwelaert Bridge by 2029, which is in poor condition due to material fatigue.
The Van Cauwelaert Bridge, located at the Van Cauwelaert Lock in a tidal area, regularly shows cracks that are periodically repaired to keep the bridge operational. These cracks are the result of material fatigue, a common problem with Strauss-type bascule bridges. Therefore, it is crucial to build a new bridge that is not only safe but also efficiently supports traffic flow in the port.
From Site Study to BIM Model
Our assignment includes the research and optimized design for the new bridge. This process begins with a site study and determining the type of bridge, followed by a preliminary and final design.
Fixed approach bridges and all necessary ancillary structures and accessories are also integrated into the design. We also study the conceptual design of the electromechanics, load distribution, concrete bridges and foundations, as well as geotechnics and BIM modeling.
Special Considerations in the Port
When developing infrastructure in a port area, it is important to consider some specific challenges early on, such as cables and pipelines, sea level rise, and traffic flow. By integrating these elements in the design phase, we lay the foundation for future-proof infrastructure.
Cables and Pipelines
The Port of Antwerp contains numerous cables and pipelines. Their management must be carefully coordinated. It is crucial to determine which utility lines will remain in use and which need to be relocated. This not only prevents disruptions but also ensures efficient execution of the work.
Sea Level Rise
With the increasing sea level rise, it is necessary that the Sigma dyke on the right bank of the Scheldt, which provides protection up to 11 mTAW against storm surges, seamlessly connects to the new bridge. This requires a thoughtful design, carefully assessing the height of the bridge above the water level. This ensures the safety and accessibility of the waterways.
Minimizing Disruption
During the execution of the work, the principle of minimizing disruption is central, especially for the daily activities of the port. We aim to minimize interruptions to both road and maritime traffic.
