【 摘 要 】

The road and railway infrastructure in Poland has been intensively developed and modernized for the last years. Around 300 new bridges are built annually. Among the new structures there is a group of modern extradosed bridges. This paper presents examples of short-, medium- and long-span extradosed bridges designed and built in recent years in Poland. The following structures are described in details: - the first Polish extradosed bridge; - two-span landmark viaduct over motorway; - multi-span curved motorway bridge; - the longest Polish extradosed bridge; - tramway extradosed bridge; - conceptual designs. The paper is concluded with geometrical parameters characterising presented structures. The parameters are compared with values obtained for cable stayed bridges and extradosed bridges built worldwide.
