The suspended deck contains around 16,000 tonnes of steel in total. It was built in sections, each about 18.1m long, in order to make their fabrication, transport, and installation more manageable.
A typical deck section weighed around 140 tonnes and was hoisted into position from a pontoon on the river, using tackles on the main cables. Work on this phase began in November 1979 and continued through the winter. The operation was in full swing by the time this photograph was taken, at some point during late 1979, early 1980.
