To improve the traffic flow in the Antwerp region, it was decided to complete the R1 Ring road by building the Oosterweel Link. The initial solutions were considered either non-sustainable or were out of budget. The final solution, explained further in this project presentation, resulted in a pioneering iso-static 2×2 lane Double Decked Cut & Cover (DD C&C) tunnel. This solution satisfies political, financial and geotechnical boundary conditions, creating a sustainable solution within the targeted budget. The final design stage is nearly completed and the anticipated construction start is by early 2019.
