To remove the old bridge gate from the Papendrecht Bridge, the contractor consortium Mobilis and Croonwolter&dros (CMCP) and its partners Hollandia Infra and Machinefabriek Rusthoven employed a unique method.

Only through broad, open collaboration can the dredging sector make the desired transition to zero-emission dredging. Rijkswaterstaat and the ZEDHub collaboration initiative are leading the sector in this effort. In September 2026, three research projects will begin to fill knowledge gaps. The results will make subsequent decisions more accurate, realistic, and less risky.
