Utter chaos prevailed on London's streets as athletes started arriving for the upcoming Olympics. A 51 kilometers long traffic jam hitting logistic problems forcing some of them to take an unintentional tour of the city. The Olympics are set to begin from the 27th of this month and the period is being described as Britain's biggest peacetime transport challenge, as contingents from 50 countries camp in the city. The first of the teams – Russia, Australia, Italy, China – arrived amidst reports that many athletes and officials had to make circuitous routes around London because untrained bus drivers lost their way en route to the Olympic Park in Stratford. Two buses containing Americans and Australians were reportedly lost, one for four hours, the other three hours this morning, even though their route was supposed to be fast-tracked by the implementation of the Olympic lane on the M4 motorway. Hugh Robertson, the sports and olympics minister, apologized to athletes who were caught up in the transport problems. But London Mayor Boris Johnson made light of the road problems by sayingthat athletes and officials took four hours then they will have seen far more of the city than they might otherwise have done.
