A BRIDGE TOO FAR
Reading about Venice’s new Ponte della Constituzione I was reminded—again—of the dangers of architectural experimentation. The bridge, designed by Santiago Calatrava, is full of novelty: irregular steps, illuminated glass treads, and a beautiful but very flat arch. All these innovations have created problems. The irregularly-dimensioned steps cause people to trip, steps make the bridge inaccessible to wheelchairs (a strange-looking mechanical pod has been added), and the flat arch has created structural stresses on the foundations. As for the glass treads—they become slippery when wet, and the glass gets chipped by tourists wheeling their luggage, requiring expensive replacement.
