The work and the technique: The Bridge over the Danube River, Romania

The Bridge over the Danube River is a complex, sustainable work. The ambitious project, the type of soil and the medium seismic level of the area, required adopting special construction techniques, like using piles with a large diameter for the foundations, excavating extended and deep shafts, besides using innovative plants to extract water from the underground aquifers.

To build the foundations, it was necessary to use anchoring construction blocks with a 47 m diameter and 31 m depth: dimensions similar only to the ones of large bridges like the Akashi in Japan, the world's largest suspended bridge.

Maximum attention was placed on the type of concrete used, which in fact made the bridge win the AICAP Prize,  which promoted Italian excellence when using structural concrete. AICAP (Italian Reinforced Prestressed Concrete) awarded the certificate for excellence in 2022 acknowledging the complex construction of the very tall towers.

To assemble the 18,000 intertwined steel threads of which the main cable that support the deck are made of, 150 people of the overall 1,350 people involved in building the work, worked for 4 months.
