Road construction / Bridge Crossing to the Russky Island Across the Eastern Bosporus Strait in Vladivostok Bridge Crossing to the Russky Island Across the Eastern Bosporus Strait in Vladivostok Commencement of construction – Q3 2008; completion – 31 March 2012.
The bridge to the Russky island will be one of the world’s largest cable-stayed bridges, the 1104 m long central span of which will establish a new record in the world bridge building practice. The bridge will also have the highest bridge towers and the longest cable stays. Bridge specification
The design of the bridge crossing has been determined on the basis of two primary factors:
Bridge Tower Construction
Central Span Structure The span structure has an aerodynamic cross-section to assume squally wind loads. The shape of the span cross-section has been determined based on aerodynamic design and optimized according to the results of experimental processing of the scale model in the detailed design phase. Welded field connections are used for longitudinal and transversal joints of the cap sheet of the orthotropic plate and lower ribbed plate. For joints of vertical walls of the blocks, longitudinal ribs, transversal beams and diaphragms, field connections are used provided by means of high-strength bolts Large-sized prefabricated 24-m sections for installation of the central span in the dedicated “windows” will be delivered by barges to the erection site and hoisted by a crane to a 76-m height. Here, the 340 t elements will be abutted and cable stays will be attached to them. Cable-Stayed System A cable-stayed system assumes all static and dynamic loads on which the very existence of bridge depends. Cable stays are not designed to endure the entire lifetime of the bridge, but they are repairable and have the best possible protection from natural disasters and other adverse impacts. The length of the shortest cable stay will be 135.771 m, the longest – 579.83 m. The protective housings of the cable stays will have the following features:
Constructing of Bridge building on island Russian will be finished in the second quarter 2012. The bridge, unique on key parametres, will be constructed in record-breaking short terms – for 43 months.
