BBC London Gallery
The cable net roof will be covered with material next Spring providing the correct conditions for athletes on the field of play and covering two-thirds of spectators.
The cable net is formed between the outer white steel roof truss and an inner tension ring 30m above the field of play.
Over 900 tonnes of scaffolding and over a kilometre of support platforms were used to assembled over 12,000m of cables and the walkways.
It took four weeks and 56 hydraulic jacks to lift the 450 tonne structure into place.
The steel support cables are made from galvanised spiral strand, with the largest cable having a breaking strength in excess of 600 tonnes.
