Olympic organizers are battling to save the $10 billion Games from becoming a fiasco, Daily Mail Online can reveal. The games are engulfed in a desperate last-minute building and repair operation as the first of more than 10,000 athletes begin to arrive in Rio. Daily Mail Online discovered the Rio Olympic authorities have their work cut out for them with only five weeks and two full days to go before the Opening Ceremony on August 5. And these exclusive pictures show, that despite being given seven years to prepare, vital roads, transport and structural work are still to be completed. In contrast, 90 per cent of construction of the venues for the 2012 Games in London was completed with a year to go. The clock is ticking down towards when the 750-strong US team are due to appear in the opening ceremony while crucial development of facilities is still needed. The combination of unfinished facilities along with safety and health fears, have also led US athletes to make late changes to their travel plans with some heading to Argentina instead to prepare. Athletes and fans will be disappointed to discover that Rio has still not managed to sign off several key venues for the 2016 games and the city is littered with Olympic eyesores.
