Krka River Bridge Near Skradin

Abstract. The new Adriatic highway crosses the canyon of the Krka river in protected environment, in proximity of the national park. The location of the bridge is in the Mediteranean area of high seismic risk. Several preliminary designs have been reviewed for this crossing, and finally a concrete arch of 204 m span had been chosen for construction. The arch cross - section is of the double ce/I box type. The superstructure is composite, comprising steel girders and reinforced precast concrete deck-plate. The bridge is currently under construction, to be completed by the end of 2004. The arch, which was completed in April 2004, was built by .free cantilever procedure, using cable-stays and steel auxiliary pylons. The steel superstructure grillage is erected incrementally in three phases, the first two from both abutments to the main piers to facilitate transport to auxiliary steel pylons and the third one launching the steel superstructure above the arch.
