A New Crossing Between Vidin and Calafat
The New Europe Bridge crosses the Danube between Vidin in northwestern Bulgaria and Calafat in Romania. Also known as the Vidin–Calafat Bridge or Danube Bridge 2, it lies on Pan-European Transport Corridor IV, adding a fixed river crossing for traffic toward Central Europe, Greece and Turkey. The principal earlier road and rail bridge on the countries’ shared stretch of river was the Ruse–Giurgiu Bridge, opened in 1954.
Vidin and Calafat had previously relied chiefly on ferries. Information later compiled by the EU Agency for Railways indicates that the crossing itself took approximately 30–45 minutes, with queues sometimes lasting five or six hours. A fixed bridge would first reduce dependence on waiting for a ferry and bring road and railway traffic to the same crossing.
The Client and Construction Team
Bulgaria’s Ministry of Transport advanced the bridge project. In its February 2007 bulletin, FCC Construcción announced a contract award of €116 million. The project combined design and construction, with Spain’s FCC as the design-and-build contractor, Carlos Fernández Casado as design subcontractor, and the Ingerop–High-Point Rendel consortium providing the client’s engineering services. The project also received EU funding.
Design papers were written jointly by designers including Javier Manterola and Antonio Martínez and FCC engineers, reflecting the combined consideration of structural design and construction methods. The deck carries four road lanes and one railway track, with cycling and pedestrian facilities. Connections on both banks had to bring these transport modes onto the bridge, extending the project beyond the river spans.
One Deck Across Different River Sections
The bridge is primarily built from precast prestressed-concrete box girders. The design papers give the river bridge a length of 1,391 meters, and the continuous system including the railway approach a length of 1,791 meters. The main deck is 31.35 meters wide, with a girder depth of 4.50 meters. The non-navigable section mainly uses 80-meter spans; the principal navigable section includes three 180-meter spans, preserving space for shipping.
The longer spans use a low-pylon cable system, often called an extradosed bridge. Inclined cables and struts help the box girder span greater distances while allowing different spans to retain the same girder depth. The designers considered changes in cable forces under train loads, and the transmission of braking and earthquake forces. Expansion joints are concentrated at the abutments, reducing the number of joints within the continuous deck.
Precast Segments, River Foundations and Lifting
The main girder was built by balanced-cantilever assembly: segments extended outward on both sides of each pier before being joined into a continuous deck. Precast concrete segments were brought to the site. Launching equipment installed those in the non-navigable section, while lifting equipment installed those over the navigation channel. Separating fabrication from installation helped coordinate production on land with construction over the river.
River foundations and the installation of large components were major challenges. The contractor’s engineering paper records bored piles up to 2 meters in diameter and 80 meters long, with some segment lifts using a 240-ton lifting capacity. Pier protection against ship impact also required many heavy precast components. For durability, the project used connections between prestressing ducts at segment joints to protect the tendons inside the bridge, details relevant to long-term maintenance.
Opening in 2013 and Later Transport Constraints
On June 14, 2013, the bridge was officially inaugurated as the second bridge on the Danube reach shared by Bulgaria and Romania. It provided a direct road and rail crossing. The EU Agency for Railways reports that the local ferry stopped operating approximately a month later. For cross-border freight, the bridge first shortened the transfer between the riverbanks.
After the river crossing was completed, however, the condition of its connecting lines continued to limit transport benefits. The agency’s 2022 report identifies slow sections and insufficient electrification on the Romanian railway toward Craiova, as well as freight restrictions on the Bulgarian side. These were conditions at the time of the report’s assessment. The New Europe Bridge removed one river-crossing bottleneck, while full use of the corridor still depended on connections, railway infrastructure and cross-border operations.
