LONG SPAN CONCRETE ARCH BRIDGES OF EUROPE

This paper provides an overview of long-span concrete arch bridges in Europe. World-record spans prior to 1997 are highlighted (Albert Louppe Bridge in France, Sandö Bridge in Sweden, Arrábida Bridge in Portugal and Krk Bridge in Croatia). An overview of recent long-span concrete arch bridges in Europe reveals new trends in arch bridge design. The bridges of wider deck are nowadays required in comparison to concrete arch bridges constructed up to the 1980s. Arch bridge design today thus often employs composite (Chateaubriand and Morbihan Bridges in France, Wilde Gera Bridge in Germany, Arco de los Tilos Bridge in the Canary Islands, Skradin Bridge in Croatia) or steel superstructure (Svinesund II Bridge in Norway/Sweden), and high strength concrete (Tercer Milenio Bridge in Spain) aimed at reducing dead load, with additional effort to design aesthetically pleasing forms and details.
