This is the most complex project within the Room for the River programme. In addition to water management measures such as the creation of a bypass channel with inlets, dike lengthening and nature development, this unique project involved the construction of three new bridges. Moreover, in the center of the river, an inhabited island is created.

The Waal river makes a sharp bend near Nijmegen and narrows at this point, forming a bottleneck. By moving the dike at Lent 350 metres inland, room is created for a bypass channel which drains the water during extremely high water levels. This feature will offer better flood protection near Nijmegen.
