The second bridge over the Danube

This project is to build a bridge for use by vehicles and rail traffic between the cities of Vidin, Bulgaria, and Calafat, Romania. It spans the Danube, constituting the second river crossing between the two countries, and it forms part of Corridor IV, which joins Dresden, Germany, and Istanbul, Turkey.

The bridge was designed by the Spanish engineering of Carlos Fernández Casado and FCC Construcción.


This is the biggest Bulgarian construction project ever. It consists in the construction of a combined bridge for vehicular and railway traffic. A total of 1,951 metres long, it contains four lanes for vehicles, a single set of electrified rails, a bicycle lane, two pavements for pedestrians and service uses plus the necessary infrastructure for the approaches for vehicles and trains.

The project consists of three clearly differentiated parts. First, there is the railway access viaduct. The other two parts involve the construction of a precast segment bridge that has 13 spans of lengths ranging between 80 metres in the non-navigable channel of the river and 180 metres in the navigable channel.

This bridge is being built with European grants under the ISPA (Instrument for Structural Policies for Pre-Accession) programme and with financing from the European Investment Bank, France and Germany.
