Tropolism means build beautiful details. In that vein, we were pleased to see this suspended wood staircase across a gorge in Traversinertobel, Switzerland. Engineer Jürg Conzett and his associate Rolf Bachofner solved the problem of connecting two different elevations over the gorge by creating a staircase. The staircase replaces a rope bridge for hikers that was wiped out by a rock slide.
