The transformation works include replacing a bridge with an aqueduct, deepening the road lay and constructing several overpass junctions. There will be an underpass for small boats and bikes with an innovative nature-friendly bank and a fauna passage. Native species of trees and plants will be used, a high percentage of recycled materials and a solar island will generate energy for the lights and pumps.

Our experts ensured that sustainability criteria were specified at every stage of the entire process and implemented in the contract.

We were also able to use our experience of BREEAM in other areas. We advised on the implementation of BREEAM-NL Infrastructure to measure sustainability levels objectively. This system provides clear criteria for including sustainability in all phases of infrastructural work. We used it to monitor the level of sustainability and further improve the requirements. The system also includes criteria for among others energy-efficient equipment, air quality, the environmental impact of materials and CO2 reduction.
Combining and integrating as many sustainability concepts as possible was a top priority for the Drachtsterweg project.

Sieds Hoitinga continues: “With high levels of sustainability criteria specified in all our contracts and excellent teamwork from Royal HaskoningDHV and the contractor Heijmans we have delivered a great result. We are delighted that Dutch Studio Roosegaarde will design the lighting concept of the road, making it even more sustainable and turning the area into a piece of art.”
