Jan De Nul and Willemen appointed as preferred bidder for refurbishment of traffic interchange at Brussels Airport

Posted on December 19, 2022

De Werkvennootschap appoints SPI.R0, a consortium of Jan De Nul and Be.Sharppp (daughter company of Willemen Group), as preferred bidder for the refurbishment of the traffic interchange on the Brussels Ring at Brussels Airport. Thanks to this facelift, the traffic interchange between the Ring (R0) and the Leopold III-avenue (A201) will happen only across one bridge over the Ring.

On demand of the Flemish Government, De Werkvennootschap searched via a competitive dialogue procedure for a suitable private partner. The consortium SPI.R0 became the preferred bidder through this procedure.

This Public-Private Cooperation is part of the bigger Program ‘Works on the Ring’. The project focuses on improving the traffic flows and safety on the R0 and A201, heightening the liveability around the R0 with an eye for nature, and a better multimodal accessibility of Brussels Airport and surrounding areas.

The existing traffic junction connecting the A201 with the R0, will become a compact ‘Single Point Interchange’. The existing flyovers will disappear and are replaced by one new bridge over the Ring. On top of the bridge, one traffic junction shall regulate the traffic flows.

Lydia Peeters, Flemish Minister of Mobility and Public Works: “This is a new, big step for the mobility and liveability in the Flemish periphery. The new infrastructure will take care of a better multimodal access to the airport area. We heighten traffic safety and -handling and also improve the transit on the Ring. Along with big investments in public transport and bicycles, this will considerably increase the accessibility of Brussels Airport and business parks. At the same time, we improve the quality of life in the surrounding residential areas and restore the Woluwe Valley, a stream which is uncovered and given back to her surroundings.”

Bart Callens, PPS-manager at Jan De Nul Group: “We are proud of the design we developed together with our partners in SPI.R0, in which we use new connections, beautiful architecture and landscaping to improve the liveability around the junction and at the same time provide a better traffic flow. We thank De Werkvennootschap for trusting our combination and look forward to presenting the design to all stakeholders together with them.”

Marc Jonckheere, CEO Willemen Group: “As CEO of Willemen Group, I am happy we can continue the long tradition of cooperation with Jan De Nul on PPS-projects in this project. The integrated approach to this file, in which landscape, architecture, drainage, building and maintenance, and reducing hindrances were taken into account, has resulted in a very high-end and qualitative project. We look forward to starting on the permit phase together with De Werkvennootschap, so we can roll up our sleeves in 2024.”

Our design focuses on new connections, beautiful architecture and landscaping in order to improve the liveability around the junction and at the same time provide a better traffic flow.

The consortium is going to be responsible for the Design, Build, Financing and 30 years of Maintenance of the new infrastructure.

In the first phase, SPI.R0 will compile and hand in the environmental permit dossier. The design will then be finetuned and extensively discussed with all stakeholders: local governments, residents, businesses, users, …

Once the environmental permit has been issued, the works can start for a duration of 3,5 years.


The new traffic situation will take up less space, thanks to which the historic Woluwe Valley wins back space. A new blue-green park valley shall connect existing residential areas and nature reserves again. Bicycle infrastructure will also be kept in mind.
