Blankenburg Link Rotterdam

Project Description

The Blankenburg Link will connect motorway A20 near Vlaardingen (North bank) to the motorway A15 near Rozenburg (South bank) by means of the new motorway A24, accommodating 2×3 lanes. The new link contributes to a robust road motorway network in the Rotterdam Area and improves the connection between the Rotterdam Port and the economic heart of the Netherlands, the Randstad.
