The precast segmental box girder forms a continuous twin-box structure 14.08 m wide, 4.0 m long and 3.20 m deep. Precision match-cast joints, multiple shear keys and advanced pre-stressing ensure superior strength.
The design minimizes weight so special heavy-lifting equipment is unnecessary, with segments weighing 69–100 tonnes.
A hybrid pre-stressing system, incorporating both external and internal pre-stressing, provides exceptional design efficiency and structural economy. Uniform segment design allows repeated formwork use and maintains a visually consistent soffit line.
