Temporary Bridge A16

Why was this temporary bridge needed?

During the expansion of the A16, it became evident that an existing structure (viaduct) no longer met modern safety standards. The viaduct over the Hoofdweg required immediate replacement. Replacing such critical infrastructure “while keeping the store open” presented a highly complex challenge, especially in this densely trafficked area. Closing the road for an extended period was not an option. Rijkswaterstaat, therefore, decided to install a temporary bridge alongside the A16.

Meeting stringent standards

Although temporary bridges are readily available in the market, Rijkswaterstaat imposed highly specific requirements for this project. The A16 temporary bridge needed to comply with ROK (Rijkswaterstaat Design and Quality Guidelines), which are stricter than the standard NEN 1090 regulations. Civiele Techniek deBoer was tasked with installing the bridge, while Rijnstaal upgraded existing components and fabricated new high-quality parts that met these stringent standards.

Together with deBoer, we cleverly utilized existing materials and supplemented them where necessary to meet ROK guidelines. The result was a modular temporary bridge that is not only safe and reliable but also future-proof, as it can be reused for other projects.

The assembly process

Constructing the temporary bridge was a challenging task. First, part of the existing structure was demolished, and a temporary foundation was installed to support the bridge. Time was of the essence. During the 2024 Ascension Day weekend, traffic was rerouted to allow work to proceed, ensuring the road reopened by Monday.

The bridge itself comprised four large prefabricated sections produced in advance at the factory and assembled on-site. These sections were installed over the weekend using Self-Propelled Modular Transporters (SPMTs)—special vehicles capable of moving large, heavy structures. This approach enabled fast and efficient installation with minimal road closures.

Innovation and sustainability

One of the standout features of this project was its circular approach. By reusing existing materials, we provided a sustainable solution that reduced costs and minimized environmental impact.

Moreover, the bridge met the highest safety standards set by ROK (Rijkswaterstaat Design and Quality Guidelines), ensuring both quality and durability.

A successful solution for a complex challenge

The temporary bridge on the A16 is a prime example of how Rijnstaal delivers innovative solutions to complex infrastructure challenges. Through close collaboration with partners, the use of circular materials, and meticulous planning, we ensured minimal disruption at one of the busiest points in the Netherlands. The bridge will be removed in December 2024, ready to be reused in future projects.

With extensive expertise in temporary structures and the ability to meet stringent requirements, Rijnstaal remains a leader in delivering safe, efficient, and sustainable infrastructure solutions.
