With exactly one year until the start of the London Olympics, construction has been completed on the six main venues in the Olympic Park: the Olympic Stadium, Velodrome, Handball Arena, Basketball Arena, Aquatics Centre and the International Broadcast Centre.
"To have all six permanent venues complete with a year still to go to the Games is a great achievement, and a firm sign that we are well on track to deliver a truly spectacular show in 2012," London Mayor Boris Johnson said in a statement released by the Olympic Delivery Authority.
Equivalent to the size of Hyde Park, the Olympic Park will have five new permanent venues, 30 new bridges and 4,000 new trees and will be served by 10 rail lines.
