Rijkswaterstaat has agreed the deal with the BAAK Blankenburg-Verbinding consortium, which comprises Ballast Nedam (15%), DEME (15%) and Macquarie Capital (70%), with financial close expected to take place in 2018.
“This totally new motorway towards the port of Rotterdam will ensure relieving of congestion at this economically important region,” said Cora van Nieuwenhuizen, minister of infrastructure and water management.
Under the €1bn deal, the consortium will deliver the new route, followed by a 20-year management and maintenance period.
The project includes the construction of an immersed tunnel under the Rotterdam port waterway, a land tunnel, two busy junctions (of the A24 to the A20 and the A15) and the widening of the A20 between the A24 and the Kethelplein.
BAAK Blankenburg-Verbinding was appointed preferred bidder for the deal in July.
