Transport minister, Jim Fitzpatrick has launched a consultation on which roads should be included in the temporary Olympic Route Network – which will have dedicated lanes for Olympic officials and contestants.
London will have a network of roads to link all competition and key venues to create the ORN.
This first consultation outlines which roads are proposed for inclusion and is open for the next 14 weeks.
Minister Fitzpatrick said: "We shouldn't underestimate the scale of the challenge, the Olympic and Paralympic Games are 20 times the size of the Football World Cup.
"That is why we are planning the best ways of getting everyone from A to B now.
"Good transport will be absolutely vital to ensure everyone can enjoy the 2012 events, whilst still allowing Londoners to go about their normal business.
While temporary, the ORN will leave a legacy including permanently altered traffic signalling, the creation of a new traffic control centre, new traffic signals and new CCTV and junction upgrades.
Mayor of London, Boris Johnson, who at first appeared to reject the ORN, has now said: "We are determined to deliver a great 2012 games, in which everyone from athletes to organisers to spectators get to venues swiftly and smoothly, avoiding the problems that have marked some previous games.
"Our aim is to bolster the reputation of London and the UK, and secure the long-term benefit of new insight in to how to manage traffic smoothly.”
The consultation runs from 11 December 2008 to 19 March 2008 and can be found at www.dft.gov.uk/consultations/open/
