"Expected to complete by July 2012, the cable cars would run 50m above the water and, according to Mayor Boris Johnson, would be ‘as good as a bus route with 30 buses on it'.
Johnson, said: 'With permissions signed and sealed we are now a significant step closer to being able to cruise the east London skyline via an elegant cable car spanning the mighty Thames.'"
Officials estimate that the gondola system will be capable of transporting 2,500 people per hour over the river.
