To promote the application of steel-concrete composite beam structure in highway reconstruction&expansion projects,it takes the widening design of the main bridge spanning the Huning Expressway on the Dantu hub of Yangli Expressway as an example,and adopts steel-concrete structure for widening design of the old bridge.Addressing issues such as limited bridge clearance,coordinated deformation between new&old bridges,and strict construction period control,which can provide reference for the widening design of similar bridges in China.
