His bridge will be a huge transparent arch, 94 metres long and 6 to 9 metres wide, with a structure of tempered steel, bronze handrails, Istrian stone risers and shatterproof glass steps. Calatrava's bridge will be the fourth to span the Canal Grande, after Rialto bridge (1588), the Accademia bridge (1932) and the Scalzi bridge (1934).
The entire arch will consist of 74 steel segments, made in Noventa di Piave. The bridge will be erected in an unusual way: the pieces will be transported to Marghera for assembly; the entire structure will be delivered to Venice by sea and set up overnight.
It will be transported by a special vessel which will cross the canal to the Giudecca.
