TfL defined a network of roads leading between venues as the Olympic Route Network ; roads connecting between all of the Olympic venues located within London. Many of these roads also contained special "Olympic lanes" marked with the Olympic rings—reserved for the use of Olympic athletes, officials, and other VIPs during the Games. Members of the public driving in an Olympic lane were subject to a fine of £130. Additionally, London buses would not include roads with Olympic lanes on their routes.    The painting of Olympic lane indicators in mid-July led to confusion from commuters, who wrongly believed that the Olympic lane restrictions had already taken effect (they were to take effect on 27 July). The A4 experienced traffic jams due to drivers avoiding the Olympic lane, and likewise on a section of Southampton Row , where the only lanes available in one direction were the Olympic lane and the bus lane.
