London Mayor Boris Johnson vowed that London transport will "cope very well" during the Olympic Games.
Speaking on a boat on the River Thames after the Olympic rings were lowered into place on Tower Bridge, Mr Johnson said: "I'm convinced that we have done everything that we can.
"The venues are ready, they are under budget, the Park is looking fantastic already, the policing situation is great, you've got all the security in place, the transport network has had masses of investment and I know that it's going to cope very well."
With only a month to go until the London 2012 Games, ITV News has been to take a look around the Olympic Park.
