The functions of urban river-crossing bridges are diversified,often carrying the multiple functions such as traffic,flood control,landscape,culture and ecology.In the design of river-crossing bridges,it is necessary to comprehensively consider various functional requirements.The total length of Linyi City Tongda Road Benghe River Bridge and Both-side Interchange Reconstruction Project is 1.725 km.The main bridge is a"reach-all-directions"4-pylon double-plane steel box girder cable-stayed bridge,which is the first large-section four-pylon one-side tension cable-stayed bridge in China.The total length of the bridge is 822.9 m,and its total width is 55.1 m.The interchanges are set up at the intersection of both banks with Binhe Road and Benghe Road,which are designed on the standard of double-way 8-lane urban trunk road.The project was completed and opened to traffic in January 2023.Taking this project as an example,the design ideas and technical essentials of the scheme are introduced from various aspects such as technical standard demonstration,overall design,bridge reconstruction,main bridge type scheme design and both-bank interchange scheme design.
