Michaux bridge Almere

Design and collaboration

The Michaux Bridge in Almere was not just a simple replacement project. Given that houseboats are located behind the bridge, it needed to be a movable structure. Although the bridge does not open frequently, it was essential that its drive mechanism be both reliable and efficient. Rijnstaal led the engineering firm Boorsma in the mechanical design, and then developed and optimized the technical components such as shafts, bearings, and the drive system. This collaboration resulted in a sleek, aesthetic design that is both functional and visually appealing.

Unique challenges

The slim design of the bridge presented several technical challenges. The mechanical components needed to integrate seamlessly into the structure without compromising appearance or functionality. Additionally, the new bridge was built on the existing foundation of the old wooden bridge, which required precision in planning and execution. A 3D survey of the substructure served as the foundation for the design of the new bridge.

The bridge consists of three sections: one resting on the main frame, a central section hanging from a tie structure, and a part suspended by the bridge’s cables. This is notable because very few cable-stayed bridges are designed to be movable.

Assembly and construction

The site was difficult to access with large equipment, so the entire assembly was conducted from the water using a crane vessel. The bridge was primarily fabricated at Rijnstaal’s workshop, then transported to Knipscheer’s yard, where it was partially assembled before being moved to its final location for installation.

One remarkable aspect of this project was the speed of execution. On-site construction took only three weeks, while bridge production took approximately five to eight weeks.

Sustainability and materials

For the Michaux Bridge renovation, durable and low-maintenance materials were chosen. The bridge deck is made of composite, a lightweight and strong material, and the hardwood railings were 3D-milled from reclaimed hardwood—a sustainable choice.

These materials greatly extend the bridge’s lifespan while minimizing maintenance, aligning with Rijnstaal’s vision of delivering robust and future-proof solutions.

With the Michaux Bridge in Almere, Rijnstaal has demonstrated that innovation and collaboration can lead to a high-quality, sustainable, and efficient solution. This project also marks a milestone as the first movable bridge that Rijnstaal carried through from design to completion.
