New Stairways to the Hard Bridge, Zurich
Four spiral staircases constructed of in-situ concrete lead from Hardstrasse to the bus stops on Hard Bridge. The self-supporting stairs spiral around a tubular lift core. A skywalk cantilevers 7 m from the lift core to the bridge, without burdening it.
Two stairways each are on Eschwer-Wyss-Platz and at the Schiffbau Theatre. They are 12 m to 15 m high, depending on the terrain.
