D4R7 is a large-scale project that will provide a radial expressway (R7) and a bypass motorway (D4) surrounding the eastern side of Bratislava. The project includes an almost-3-km long bridge formed by 4 structures: 2 approach viaducts and two balanced cantilever bridges over the Kayak Channel and the Danube River.
D4R7 CJV (D4R7 Construction s.r.o.) recently finished pouring the box-girder of the first span of the East Approach with an MSS. Another MSS at the West Approach is almost assembled. Works on the main bridges over the Danube River and the Kayak Channel are currently focusing on the substructure as you can see in the following update video.
FHECOR Ingenieros Consultores has been working since 2016 as Design Checkers of the main structures of the D4 (where the Danube Crossing is located) and the R7 (the radial motorway from Prievoz Interchange to Holice). The CJV is made up of Ferrovial and PORR AG.
