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.
On November 20th a FHECOR team formed by Alberto Martín Galán, Ricardo Bastida Marín, and Freddy Alexandro Ariñez Fernández traveled to Bratislava to witness the progress in the execution of the structures part of the project. They observed that the construction of the superstructure of both approach viaducts was significantly underway as well as that the contractor finished with the execution of the first dowel of balanced cantilever bridges over the Kayak Channel and Danube River.
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.
