Construction of Šibenik and Pag arch bridges

The Šibenik Bridge spanning 246m, built in 1966 was the first in the world to be constructed entirely by the free cantilevering method. The Pag Bridge completed in 1968 with a span of 193m is very similar in appearance and design. Three-cell box arches gradually increase depth from the springing towards the crown. They were constructed by suspended cantilever method with temporary stay cables and tie-backs anchored into the abutments of the superstructure at Šibenik Bridge and directly into the rock at Pag Bridge. The superstructure of both bridges is designed as a series of simply supported grillages consisting of four precast prestressed concrete girders joined by cast-in-place cross beams at supports and in the thirds of span. Šibenik and Pag Bridge designs were concentrated on solving the construction problems, very small concrete cover was utilized, which subsequently led to durability problems. Over the years many deficiencies and advanced stage of deterioration processes were identified on these bridges, as a consequence of extremely aggressive exposure conditions, but also of conceptual design and errors and negligence on site.
