Ripollet Viaduct on the C-58 motorway (Barcelona)

The Viaduct, consists of an elevated structure whose piers are located in the space between the two decks of existing viaduct, belonging to the C-58.

The deck consists of a spatial steel tubular structure that supports a concrete platform, on which the carriageway runs.

Unknown for this type of structure, the design of the construction system involved erecting the piers and deck 100% without the support of the existing viaduct decks which were only occasionally used for auxiliary aid jobs, control and inspection so that traffic was not cut off at any time.
