Attempts at relieving the gridlock are hampered by a lack of coordination between police services overseeing different sections of the motorway, leading to cases of traffic being diverted onto the same roads in opposite directions. Traffic that managed to work its way through the diversion route past the Surrey accident suffers a further setback when a chemical tanker lorry jackknifes on the M25 near to Heathrow Airport, causing a pile-up and further tailbacks, resulting in a second closure on the M25, and heavy delays on the M1, M2, M3, M11 and M20, the major artery-roads leading to London. Traffic attempts to drive through Central London, without much success and The Channel Tunnel is closed due to the Rail strike and all traffic is rerouted to Dover for Ferries and Eurostar Passengers are put on Flights.
