Ten years from now the Emscher River in Germany, currently a canal between two dykes, will be returned to its natural state as a river. In celebration of the renaturification, the Dutch art group Observatorium built a habitable wooden bridge from reclaimed timbers to span the space where the river will eventually flow again. For the summer of 2010, Warten auf den Fluss was open to visitors and overnight guests so they could explore the area and experience the land that would soon be taken over by the river.
