The main structure is made by a 340m x52m spatial truss. At the longitudinal ends this truss height decreases from 3.6m to 0m following a double spliced profile.
This structure is supported in 20 points by: columns at +9.00m level of existing bridge structure, new columns at -4.50m level, concrete cores.
This structures hangs with hanging tubular elements 8 peculiar structures named “Suspended Volumes”. These structures are made by a steel and wood deck and a steel CHS profile cover.
Due to their peculiar shape, the cover structure is vertically connected to the vertical rods with a vertical regulation system that allows to got the correct position during erection; roof cover profile should then be fixed to the hanging rods in order to avoid any relative horizontal displacement.
