Thanks for update of world's highest pier railways bridge. This video is prepared with great risk as seen but only one of its kinds. How much concrete layer can reach top stage of 4p? One concrete stage would required at least 3 days gap so assuming 2 meter per one layer could reach top of 141 meter in 210 days. Therefore 7 months time will be required even if 24x7 works. Hope more videos till rail reached Imphal.
