English: Glass tiles on Zubizuri bridge, Bilbao. One of them is broken, but it stays on the floor until the arrival of the replacement (having different shapes, there is not one replacement tile which fits in every position). Gary transversal lines are stripes sticked to the floor in order to prevent pedestrians to slip
Español: Baldosas de cristal en el puente Zubizuri, Bilbao. Una de ellas está rota, pero permanece en el puente hasta que llegue el recambio (al tener formas diferentes no vale el mismo repuesto para distintas posiciones). Las líneas grises transversles son tiras antiadherentes pegadas para evitar que los peatones resbalen.
