The bridge over the Cavalls Gorge consists of four spatial composite truss girders of 56,00 m span, 3,00 m depth and 4,00 m width that put together provide a deck of 17,00 m width. In order to optimize the use of structural steel, the bottom chord, which is tensioned, has been pre-compressed by means of exterior pre-stressing, made up of two units of 24 parallel strands of 0,6’’.
The trusses were built with the help of framework and a crane. The concrete of the deck slab was cast over the steel structure. Finally, the exterior pre-stressing was tensioned.
