2012 Olympic Stadium lights up
29 March 2010
New aerial images from the London 2012 Olympic Delivery Authority (ODA) show the Olympic Stadium's lighting towers have all been lifted into place 60 m above the field of play, taking the flagship venue to its full height.
A total of 14 lighting towers, each weighing 34 tonnes and designed with integrated walkways, access, power supplies and cabling and lighting, were lifted into place over three weeks.
The cable net roof will now start to be covered with a fabric material, providing the correct conditions for athletes on the field of play and covering two-thirds of spectators.
ODA Chairman John Armitt said: "The successful lift of the lighting towers takes the Olympic Stadium to its full height and makes it even more visible across east London's skyline.
"We still have big challenges over the coming year but hitting this important milestone ensures we remain on track to complete construction a year before the London 2012 Games begin."
The lighting towers, which will illuminate the action on the field of play and are necessary for high definition television footage, are located high above the Stadium roof to ensure optimum lighting angles which avoid dazzling spectators, photographers and competitors.
Each tower can house up to 44 floodlights and a team of electricians installed and tested each light on the ground before the towers were lifted 60 m on to the inner tension ring of the roof structure.
Over the coming months, the power supply and control cables will be installed and a series of tests will be carried out to ensure that every individual bulb is position correctly.
