Olympic rings on London's Tower Bridge mark one month to games

Five giant rings were lowered off London’s Tower Bridge over the River Thames Wednesday, bringing the famous Olympic symbol to one of the city’s most recognizable landmarks to mark exactly a month to go to the start of the 2012 games.

The rings - 82 feet wide and 37 feet tall - are part of efforts to bedeck the city in Olympic banners ahead of the competition, which starts on July 27 and ends on August 12.

The rings weigh three tons and cost more than $300,000 to produce, but have a highly symbolic presence on the bridge, which sits opposite the Tower of London and acts as a gateway for river traffic to the city center.

London Mayor Boris Johnson promised the city will “cope very well” during the games.

Speaking on a boat on the river, he 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."
