Blankenburg connection

In addition to the Van Brienenoord bridge and the Benelux tunnel, the Rotterdam area will get a third crucial connection between North and South: the Blankenburg connection. This will link the A20 at Vlaardingen to the A15 in the port area, giving rise to a number of significant positive impacts on the accessibility and economic situation of the entire region. Rijkswaterstaat has commissioned us and our consortium partners, DEME and Macquarie Capital, to create this new and impressive connection. It will feature two intersections, a land tunnel and a tunnel beneath the River Scheur.

The A24, the new motorway that is to be constructed, is part of a four-kilometre series of technical constructions. It will feature a sunken intersection at the A20, followed by a sunken road section and then a land tunnel, so as to leave the landscape intact. There will also be two viaducts crossing a road and a railway, a dam and then the technical highlight: a 945-m long tunnel beneath the River Scheur. The final section is an above-ground intersection with the A15.


Special contract, close collaboration

The assignment includes the design, building, 20 years of maintenance, and the entire financing of approx. EUR 1 billion. We are doing this extraordinary assignment with a special project organisation, one that brings together the expertise and manpower of several different disciplines in a close team. This will enable us to ensure efficient, high-quality work and a timely delivery to Rijkswaterstaat. The latter is important, since the new link should be open to traffic in 2024.


Looking at the project from the region's perspective

The reference design was based on six tunnel sections that would be brought to the immersion location by water. However, the actual water tunnel is now going to be achieved with only two immersed sections. These will be constructed on-site, one on each bank of the river. This minimises the number of times that the Nieuwe Waterweg – the economic artery of this region – will have to be closed for traffic. We are also going to share our architectural and building expertise in local schools and give students tours of the building site. We will also employ local workers where possible meaning that the area will benefit in every respect.
