Sažetak
Two small railway flyovers in the city of Osijek, Croatia, at a short distance between each other, were in such condition that they had to be replaced by a new structure. The railway authorities imposed a choice of a concrete superstructure and to lead the bal-last along the structure. Given the distance between the extreme abutments of about 46 m, a two-span non-continuous prestressed concrete trough bridge was adopted. The railway traffic had to be maintained during construction. Therefore the superstructures were built on scaffolding beside the flyovers and were laterally launched onto the supports after pre-stressing. The superstructures pertaining to individual spans have been built subsequently. The substructure consists of abutments arranged in the form of a space frame, and the middle support is a plain frame. The cross-beams of these frames support bearing pads and the columns of both frames are a direct continuation of bored piles. The construction is underway and is scheduled for completion in spring 2006.
