Jarun City Bridge-Preliminary design

A new bridge across the Sava River in the city of Zagreb is to be built to link the south entrance into the city with the west of the city. The City Council of Zagreb and the Croatian Society of Structural Engineers organized a public competition for the preliminary bridge design. Ten alternative proposals were entered by different design teams, comprising both bridge engineers and architects. In this paper all ten bridge proposals including beam type bridges, through and half through arch bridges and cable-stayed bridges, made of concrete or steel or of composite type are shown. Particular emphasis is given on the asymmetrical cable-stayed concrete bridge, which was awarded the first prize. The main span is 150 m with the overall bridge length of 625 m. The superstructure is a continuous box type prestressed girder with constant depth of 280 cm over eleven spans. The inclined concrete box-type pylon is 88 m high of which 75 m are above the superstructure.
