4-section structure
The structure has been installed in 4 sections. The motorway had to be closed to allow Kamag transport the first 3 sections. The 4th section will be constructed on site.
Each section weighs close to 400t, made up of the steel frame (200t), precast slabs and other components (200t).
The welding work was carried out after the sections have been installed, followed by reinforcement of the deck before concreting. The work was carried out in several stages and included night work.
