<p>The paper deals with specific design and construction of Roadway Bridge across Tissa River in Ada town (autumn province of Vojvodina, republic of Serbia). The special task was to design and construct a new bridge across Tissa in Ada by using the donated dismantled steel structure, removed form the piers of former bridge across the Danube in Wilshoffen (Germany). The superstructure – steel structure of the former Wilshoffen bridge had structural system of continuous beam, with total length of ~258 m and modest spans: 4x25,8 + 64,5 + 3x25,8 + 12,9 m. The dismantled steel structure, cut in 6 large segments, was transported by barges downstream Danube through Danube-Tissa Channel and stored nearby Tissa River. These stored segments of steel structure should be incorporated in new bridge across Tissa River in Ada, taking into account the relevant local conditions: profile of river bed, geotechnical profile of soil, required river flow profile, required (larger) navigation clearance, water regime data; as well as other relevant circumstances: transport, erection & adoption of steel structure, economic aspects and aesthetic appearance. The larger main span was needed, that required the modifications of the steel structure stored segments. It was adopted the vertical alignment of the former Wilshoffen bridge, because of the undisturbed reconstruction of the orthotropic deck. The Ada bridge was preliminary designed as steel cablestayed bridge, with spans: 2x25,8+90,3+4x25,8 m, having a steel A-pylon. The chosen design-built contractor Inter-Most Belgrade (subsidiary of Vinci Construction) modified the design into steel cable-stayed bridge, with only two spans: 77,4+167,7 m, having a concrete A-pylon (single river pier advantage due to foundation costs). The cable stays are constructed by Freyssinet. The building works, started in June 2006 and to be completed in June 2008, are presented in the paper as well.</p>

<p>The paper deals with remarkable bridges across Sava River in Belgrade that can be treated as the monuments of technical development of bridge engineering. The first one is Branko’s Bridge, built in 1956 (as steel plated continuous beam structure, with 261 m main span – exrecord in its category), widened in 1978, on the piers and abutments of former suspension bridge (built in 1934, largely damaged in 1941 &amp; destroyed in 1944). The second one is Gazelle Bridge, built in 1970 (refurbished in 2012) as steel shallow-frame structure, with 250 m main span - ranked at 3rd place in its category. The third one is double-track Railway Bridge, built in 1979 as the steel cable-stayed structure, with 254 m main span. This is the first cable-stayed bridge for railway traffic only. The fourth one is Ada Bridge, built in 2011 as cable-stayed structure with 376 m main span (steel) &amp; 250 m (back span), having original single cone shaped 200m high concrete pylon.</p>

<p>The paper presents the project realization of the Roadway Bridge across Vistula River in Plock (Poland) as it was designed, built and open for traffic in October 2007. The bridge, having width of 27,5 m and total length of 1.200 m, consists of two different parts: main bridge part (length of 615 m) over the Vistula riverbed and access bridge part (length of 585 m) over the inundation. The main bridge structure is steel cable-stayed bridge consisting of: continuous bridge girder with orthotropic deck (main span of 375 m and side spans of 2x60 m each), cable stays in the single plane and two obelisk-type pylons fixed in the deck. The access bridge part consists of two bridge structures with composite deck, having structural system of continuous girder, spanning 5 x 58,5 m each. The bridge, as the part of modern bypass, is well incorporated in the environment - plain terrain on the left bank and hilly landscape on the right bank featuring Plock town.</p>

<p>The paper deals with new bridge across Sava River in Belgrade, with an overall length of 967 m, at the lower tip of Ada Island as a part of the inner city semi-ring road. The bridge deck, having width of 45 m, carries 6 lanes of vehicular traffic, 2 rail tracks of LRT and two lanes of pedestrian/ cycleway. The main bridge part is an asymmetric cable-stayed structure, with a main span of 376 m and a back span of 200 m. The unique single pylon in the form of sharp cone is 200 m high. The stays of fan-type configuration are in two quasi-middle planes. The aesthetics plays a major role in bridge design to be a meeting point for engineering and architecture. The Ada Bridge will have an original architectural appearance well incorporated in the city environment. As the awarded design-build Contractor started the works by middle 2008, it is planned to end the works in autumn 2011. The Sava Bridge is the largest bridge currently under construction in Europe.</p>
