This video presents the complete construction workflow of a river bridge and its connecting roadway, compiled from multiple stage-wise clips into a single sequence.
The process begins with cofferdam construction and deep foundation works, including excavation, sheet pile installation, dewatering, and foundation preparation within the cofferdam. Reinforcement placement and concrete casting are carried out to form the foundation base, followed by pier construction through staged reinforcement, formwork, and concrete pouring.

Superstructure works include installation of bridge bearings, placement of girders across spans, and installation of precast deck slab panels. Deck reinforcement, formwork, and in-situ concrete casting are then completed, followed by curing and formwork removal. Approach road construction includes embankment formation, sand filling granular sub-base placement, aggregate spreading, and mechanical compaction using rollers with water-assisted compaction.
Final stages include asphalt paving across the bridge deck and approach roads, compaction, installation of railings and lighting systems, precision road marking using automated equipment, and side slope finishing with soil dressing and turfing
