A section of a main road route into London had to close today as rush-hour travellers mixed with Olympic traffic on the first working day during the Games.
A serious accident meant the closure of the London-bound section of the M4 between junction 5 at Langley in Berkshire and junction 4b near Heathrow airport in west London.
Long queues built up on the motorway which goes into an Olympic traffic-only Games lane nearer London.
There were also jams for drivers at some of the Games lanes sites in London, including the A40 in west London and the Canning Town Flyover in east London.
But Tube and main line rail services operated well during the morning peak period.
