The Mayor's unveiled London's first two 'Cycle Superhighways'.
The pilot routes run from Merton to the City via the A24 and the A3 and Barking to Tower Gateway via the A13 and Cable Street.
Around 5,000 cycle journeys a day are currently made on the routes and the aim is to increase that to 27,000 by 2013.
