The superstructure was a P.S.C. box girder, one for each carriageway, constructed using balanced cantilever cast-in-situ segments.

The Franki piling system (also called pressure-injected footing) is a method used to drive expanded base cast-in-situ concrete (Franki) piles.

The use of self-climbing forms made it possible to achieve better quality and decrease the time of construction of cast-in-situ reinforced concrete structures by half as much again.

The basic construction consists of cast-in-situ reinforced concrete columns and walls that are clearly visible on the facade as horizontal and vertical lines that follow the logic of the existing structures.
