Railway road bridge in Novi Sad - Design and erection

Abstract

The bridge is situated on the major international electrified railroad line No 2 (Belgrade-Budapest) and designed for to railway tracks (160 km/h), two road lanes and two footpaths, with the total width of 31,5 m. The bridge structure consists of four structures: two approach composite bridges at the banks and two steel tied network arch bridges over the river. The spans are 27,0 +177,0 + 3,0 + 219,0 + 48,0 m, totally 474,0 m in length. The heights of arches are 34,0 m and 42,0 m respectively. The arches and ties, as well as the girders of the approach spans, are steel box girders. The decks of the arch bridges are the composite reinforced concrete slabs with thickness of 300 mm. The launching itself is very complex and unique, in both analysis and construction. The arch bridges are fully assembled on the banks and launched by platforms and skids over the bank and by barges over the river, to the final position on piers.
