London 2012: construction progress

As the International Olympic Committee's inspection team comes to town for a routine visit, London authorities on Tuesday released a series of photos that underscore the undeniable progress made at Olympic Park. Here's one showing the central stadium. The Olympic Delivery Authority, as the construction oversight entity there is called, recently announced that work is 75 percent complete, with the main venues on track to be completed next summer, a year before the Games. The opening ceremony is set for July 27, 2012.
