A6 Motorway
Project overview
Commissioned by Rijkswaterstaat, BESIX led the design, construction, financing and maintenance of the A6 upgrade. Works focused on widening the motorway from two to four lanes, as well as renovating interchanges, bridges and viaducts. Reducing disruption on this busy transport corridor was a key priority, with night works and phased lane renovations ensuring smooth traffic flow throughout delivery.
Scope of works
BESIX, in partnership with Dura Vermeer, RebelValley and John Laing Investments Limited, delivered a full lifecycle scope for the A6. This included the design of the wider motorway, the renovation and expansion of the existing lanes, and the renewal of surrounding infrastructure. The team also secured and managed project financing and provides long‑term maintenance for 20 years. Close collaboration with residents and the city helped shape practical solutions, including low‑noise asphalt at the busiest sections.
