In pre-cast bridges, concrete segments like beams, decking and flanges, constructed offsite normally at the precast manufacturing plant and then transported and hoisted into place. As the new segment suspends from the crane. Workers install steel reinforcing that attaches the new segment to preceding segments.
Each segment of the bridge, designed to accept connections from both preceding and succeeding segments. Precasting bridges allows engineers to construct a bridge quite quickly for time. Precious projects like active rail bridges who cannot afford much downtime making it a highly cost effective solution.
