A segmental bridge is a bridge built in short sections (called segments), i.e., one piece at a time, as opposed to traditional methods that build a bridge in very large sections. The bridge is made of concrete that is either cast-in-place (constructed fully in its final location) or precast concrete (built at another location and then transported to their final location for placement in the full structure).[1]
These bridges are very economical for long spans (more than 100 metres or 330 feet), especially when access to the construction site is restricted. They are also chosen for their aesthetic appeal.
