Bridge structure: two parallel girder bridges with wedged steel supports acting with the rc plate. Innovative characteristics of the bridge:
− The innovative structure of the rc deck slab and the method of its dimensioning allowed to omit completely the interim temporary supports and to minimize the relocation/moving of the supports, timeand work consuming activities.
− The construction of the deck slab started with the concreting of the sections above the piers.
− Almost all connections are welded − First application of large thickness (vmax=100 mm) boom plates
− The steel structures of the bridges (2x1050t) were mounted on the riverside and floated as 1 completed piece to their place
in longitudinal and transversal direction, by means of floating and lifting engines.
