London 2012 Olympics: new pictures of the site with two years to go

The main arenas at the Olympic site in Stratford, east London are fast taking shape. Here, some of the construction workers have downed tools and formed a No2 formation on the F10 bridge to mark the countdown Photograph: LOCOG via Getty Images

The main stadium - costing a reputed £537m - developed rapidly over the past 12 months. The roof and upper tier, which can be dismantled after the Games, is in place, as are the floodlights, while the surrounding infrastructure is still being built Photograph: LOCOG

Now this might look pretty from the outside, but it's purpose isn't quite so pleasant. It's a pumping station which, together with a new sewer network, will collect, convey and discharge waste from Olympic site Photograph: LOCOG
