Completed in 2021
As a part of the Bratislava D4R7 bypass, a 2,932 km long bridge structure, consisting of a bridge over the Danube River, a bridge over a Rowing Track and an eastern and western approach viaduct, was constructed. The bridges, which have a unified architectural and structural solution, have a 35.0 m wide deck consisting of a spine box girder with large overhangs supported by precast struts. The bridges over the Danube and the Rowing Track were cast segmentally in symmetrical cantilevers starting at piers. At first, the spine box girder was constructed, then the overhangs were progressively cast in the travellers moving on the already completed structure.
