Description of works

The construction of the Calafat -Vid in lnternational Bridge, is split into two construction sections:

Railway Infrastructure

The construction of a new 3.3 km single-track was carried out, extending from the end of the bridge on the Romanian bank of the Da nube to the existing Golenti-Calafat, including a new link to Calafat. In addition, the existing main and secondary lines were fully rehabilitated at the Golenti railway station. The section also involved the construction of electrical substations, catenary and railway signaling a long the entire length of the track, in accordance with the European ERTMS level 1 standard.

Road Infrastructure

This included the construction of approximately 8.7 km of road, mainly concentrated on the new access junction on the Romanian bank of the bridge. This section consisted of 3 km of highway, with two carriageways and two lanes in each direction. In addition, two viaducts, two overpasses and a toll station were built.

Main challenges

One of the major challenges was the viaduct of the DN56 road, which consists of 13 double spans, one for each road, with a length of 26 m per span, using prefabricated beams of 1.03 m depth. Each deck was 18.5 m wide and approximately 344 m long.

Another major challenge was the railway viaduct, with 11 spans of 26 m each, a cross section of 11.9 m wide and a total length of 290 m.

Sustainability

During construction, important safety measures were implemented to avoid impacts on the Danuvio River (sediment barriers, physical barriers, river flood control).
