Monday saw the introduction of the first reusable concrete flyover in the Netherlands. The flyover bears dismantling without any residual waste, to be used again. Thus, it boasts a lifespan of some 200 years. The lifespan of a standard flyover is 30 to 50 years.
The flyover between the cities of Kampen and Dronten was put into use on Monday – the first day of the Circular Economy Week – in the presence of State Secretary Stientje van Veldhoven (Infrastructure and Water Management). The first vehicle to cross the flyover was an (electric) lorry.
Circular design and construction
Ms Van Veldhoven: ‘This flyover is a fine combination of sustainable ambition and common sense. Constructing flyovers out of standard building blocks that can be reused elsewhere benefits the climate: it avoids wastage of raw materials, while opening up opportunities for faster work and cost reduction. This is why Rijkswaterstaat – the executive branch of our Ministry – aptly says: “we intend to work in a circular fashion by 2030”. This flyover marks an excellent step in the realisation of this ambition, and it can serve as an inspiration to the whole of the Netherlands – and the rest of the world. Circular design and construction is feasible, and big business’.
The 40 separate elements of the flyover are removable. This makes it easier to adapt the flyover, for example by adding an additional lane or new exit. The flyover can even be relocated in its entirety. In March 2019, the entire structure will be dismantled. Until such time, it will be used by construction traffic in the purview of the construction of the Reeve sluice.
The introduction of the circular flyover is well timed. Until 2028, Rijkswaterstaat has scheduled at least 80 major overhaul projects. Many bridges and tunnels date from the 1950s and 1960s and are due for a makeover. The findings with respect to the reusable flyover will be taken into consideration in these projects.
Economy without waste
The Netherlands is working hard on becoming an economy without waste by 2050: a circular economy. Continuous reuse of raw materials opens up major opportunities for the business community and helps to achieve the Dutch climate goals.
