− The substructures of the bridge are supported by vertical and inclined driven rc piles, prefabricated with centrifugal  technology.
− The innovative structure of the rc deck slab and the method of its dimensioning allowed to omit completely the relocation/moving of the supports and the prestressings, time- and work consuming activities.
The deck slab was concreted without application of interim temporary supports. The deck slab was concreted without the application of interim temporary supports.
