This bridge encompasses big span, heavy load with maximum single vehicle of 160t, upper supporting construction, broad deck, proper sight line, major girder of steel slab construction, and excellent bridge sight effect. The bridge employs combined girder construction of steel slab and concrete, in-between segments uses friction-type high strength bolts, and shear bolt are employed between steel slab girder and concrete deck. Fully make good use of the characteristics of high tensile strength of the steel and high compressive strength of concrete. Therefore, this bridge is suitable to the construction of highway bridges of various levels.
