A6 Almere

Rijkswaterstaat – the executive agency of the Dutch Ministry of Infrastructure and Environment – has entrusted BESIX with widening the A6. The Group managed to win the project by submitting an exhaustive quality plan, which described the impact on the local residents and surrounding nature in great detail.

BESIX is responsible for the design, construction, financing and maintenance of the A6. The works started in 2017, and apart from the widening of the road from two to four lanes, also included the renovation of interchanges, bridges and viaducts. The project had to increase the capacity of the highway and improve the flow of traffic to and from Almere.

BESIX has joined forces with Dura Vermeer, RebelValley and John Laing Investments Limited. The consortium is responsible for:

• the design of the new, wider A6;

• the renovation of the existing road, widening by two additional lanes in each direction, and revamping of the surrounding infrastructure;

• attracting and monitoring financing;

• maintenance for 20 years after project completion.

An absolute priority for this busy traffic axis was to limit inconvenience during the works. To do that, the Group first renovated the existing lanes, which was followed by the construction of the additional lanes. Some of the work was done at night to minimize traffic disruption.

BESIX managed to win the support of the city of Almere and local residents by inviting them to the discussions and fostering their active involvement in the project. The Group translated their input into practical actions, with the use of noise-reducing asphalt for the busiest segments of the broadened motorway, for instance.

In addition, the works were performed with respect for the surrounding nature. This ensures the liveability of the area, not only for the inhabitants of the city, but also for the local fauna and flora.
