The main bridge adopts a pile foundation with a diameter of 2.0m (length 93m), 19.2×14×4m low pile cap, 8.5×5m thin-walled rectangular hollow pier (high 18.5m), and the upper structure is 3×(100+4×140+ 100)m variable section continuous beam, a total of 18 suspended sections. During the construction process, a complete set of cross-river multi-span highway bridge construction technology is successfully developed, which is successfully applied to the construction environment of deep water, rapid flow, complex geological conditions with high geological conditions and high operational risk in the main channel of the Yellow River.
