Public Drawing – Cross Concrete Crossing

  • Waldlabor
  • Where humans, animals, and elements cross, a concrete bridge spans the untamed riverbed of the Holderbachtobel above Zürich Affoltern. The weather-carrying westwind rushing over the canopy crosses a faint cold air stream flowing down the creek.
  • Below, a bridge crosses over a deer trail stamped into the eroded riverbed.
  • Similar crossings layer through shrub and canopy, rising high into the sky, leaving a network of interactions, some of which may only be discovered on second or third glance.
