This looks like the Detroit olympics. I was in Beijing a year before the olympics there. I talked to a few people about the olympic venues. They were well aware there that most cities lose money and the places fall into disrepair. They had plans for many of the buildings to be reused, but some of them, including full modern stadiums, were declared temporary to be knocked down shortly after the olympics. The "bird's nest" signature building was supposed to survive and become the home stadium of a professional team, but last I read it was falling into disrepair.
All in all these are a gigantic waste of money for these cities. Only the Los Angeles olympics that I know of made money, by reusing existing buildings as much as possible.
