Design of the Danube Bridge at Mohács

The next Danube-bridge of Hungary has recently received the green light for its construction, to be located in south-central Hungary, near the historical town of Mohács. The town and its surrounding region have long awaited the construction of a permanent bridge to establish a lasting connection between the two sides of the Danube. The 756-meter-long bridge structure comprises three spans, supported by only two intermediate piers. These piers are strategically located: one in the floodplain forest and the other in the shallow waters of the Danube’s left bank according to the environmental and water management restrictions. This arrangement divided the structure into three sections, consisting of a series of 230-meter, 250-meter, and 270-meter tied arch superstructures with orthotropic decks are made from S355 and S460 steel. The arches are constructed with a network suspension system, which allows an efficient and cost-effective structure. The width of the bridge is 22,82 m, consist of 3,30 m bicycle road and 2x2 traffic lanes. The structural height of the superstructure is 2,73 m. The arches made by 1,60 m width and various high box girders connected by network layout steel pipes cross girders. The stiffening girders of the tied arch bridges are 1,64 m wide and 1,80 m high box girders, connected with open cross sections a various height “I” cross beams. The cross beams support the orthotropic deck in every 4 m. The network arrangement suspension cables are arranged into different planes. Monitoring system installed on the bridge will enable real-time control during operation.
