Roads that will only be accessible to official Olympics vehicles during the 2012 games have been revealed by the Olympic Delivery Authority.
More than 60 miles of key routes will be closed including the West Way, the Great Western Road and A4 near Earl’s Court.
The lanes are to be used by the 'Olympic family' so they can run freely across London to and from the games and not be held up in traffic.
The 'Olympic family' includes 24,000 Olympians with their teams and an additional 25,000 'marketing partners'. The move to allow sponsors on to the express routes has attracted much criticism.
Richard Tracey, spokesman for the London Assembly Conservative Group, said that because some sponsors would be staying in “plush hotels in the west end”, the major route along Park Lane would be partly closed.
The lanes form part of a wider Olympic Route Network (ORN), which will cover more than 100 miles of roads in central, east and west London, including Euston road outside St Pancras and Euston railway stations, Park Lane near Hyde Park Corner, and The Mall near Buckingham Palace.
They will typically be open from 6am to midnight, and a further 171 miles around the rest of the country will also be closed off.
Not all roads in the ORN will have games lanes, but they will be subject to side road closures, banned right turns, changes to traffic lights and pedestrian crossings and adjustments to bus and coach stops.
Motorists flouting the rules will face a £200 fine.
