The opening ceremony of the Olympic games on 27th July coincides with the Friday rush hour and the holiday get away traffic, all leaving the capital via corridor routes and the M25. A worst case scenario the entire M25 could grind to a halt.....
Many parts of London will be busy during the games ( Good Luck Great Britain!) as events take place all over the capital, the level of impact on the roads will vary by day, time, and location. Some events and Olympic infrastructure will cause some roads to operate differently, either throughout, or at different times of the Games.
