<P> The bridge is a dual , tied arch bridge or bowstring bridge . It has a pair of continuous , differently - sized structural steel arches with suspended precast concrete decking and one asymmetrically placed river pier . The tapering arches with a trapezoidal box section are fabricated from weathering steel plate . The arches both bifurcate within the spans to form a double rib over the river pier . A reflex piece between the two arches holds them together making the two arches one continuous curve . No other bridge is known to have quite the same design . </P>
