Abstract: This paper deals with the acture state and new trends in cable-stayed bridge in the world. In recent years, the cable-stayed bridges with composite stiffening girder were increasingly in long span ranges of 250 m to 465 m. The design and some aspects of the structure of Annacis Island bridge which is the world's largest span cable-stayed bridge are prensented here. It has 5 span (50 m+182.75 m+465 m+182.75 m+50 m) composite stiffening girder suspended at the "H" shape R. C. towers by paralled wire cables with a narrow spacing of only 9 m. The tower height is 154.3 m above top of pilecap.
