The long decks were raised using an innovative method called "incremental launching", in which each long section was pulled across the river using a long steel truss weighing 300 tonnes. This process was repeated five times until each deck spanned the river, supported by six temporary piers made of steel and concrete. The seven 25-tonne pylons were then raised over the subsequent two weeks. Once the pylons had been installed, the decks were jacked up to enable their connection with the cable stays suspended from the pylons. The concrete deck was then lowered into its final position and the temporary piers and supports were dismantled.
