The total length of the bridge is 5.5 km (3.4 mi) comprising forty-three 125 m (410 ft) spans and two 70.75 m (232 ft) end spans. The bridge crosses a 2,250 m (7,380 ft) wide active river channel.

The 24 m (78 ft) wide deck carries four traffic lanes, shoulders, and two pedestrian walkways. The superstructure consists of a variable depth precast segmental single-cell concrete box girder stiffened with exterior struts. Moment resisting hinges are typically located at mid-span every three spans.

The connection between the superstructure and substructure is monolithic with vertical post-tensioning. The upper portion of the piers located above high flood level consists of twin walls with a pier cap on top. The piers are supported by 2.5 m (8 ft) diameter pile foundations. The bridge is built in balanced cantilever with an overhead gantry.
