New Ways for Europe: Pan-European Corridor 5

Pan-European Corridor 5 is one of the main artery linking Barcelona in Spain with Kiev in Ukraine. The idea of creating traffic corridors across Europe emerged after the end of the Cold War. Since then, modern infrastructure has been developed in order to facilitate the exchange of goods and commodities as well as passenger traffic between Europe and the Balkan States.


Leading from Hungary and Austria to the Port of Koper in southern Slovenia, Highways A1 and A5 in Slovenia form part of European Corridor 5. The connection of the Port of Koper with important Slovenian cities and with surrounding countries is significant because Koper is the second largest harbor on the north-east Adriatic Sea. The harbor makes it possible to connect important cities in Central and Eastern Europe with the Far East and Mediterranean countries. Thanks to the modern motorway connection, goods can be transported faster and more efficiently from Koper to Slovenia and Europe.

DSI Headquarter Operations contributed to a section of Highway A5 from Maribor to Cogetinci near the Hungarian border. Several retaining walls had to be constructed for this section. The retaining walls are up to 350m long and up to 40m high and have gradients ranging from 45° to 68°.


The stabilization of the retaining walls consisted of reinforced concrete grids, vertical concrete girders and piles that were anchored with Electrically Isolated Permanent DYWIDAG Strand Anchors. DSI supplied a total of 850 Type 4x0.62" DYWIDAG Strand Anchors with 3 or 4 strands and Type 7x0.62" DYWIDAG Strand Anchors with 5 strands for five slope stabilization projects.

The strand anchor systems complied with the Slovenian Technical Approval. In addition, DSI supplied the necessary grouting and stressing equipment. Work on this section began in March 2007 and was completed in August 2009.
