Since its completion in 1986 the M25 London Orbital Motorway has carried a rapidly increasing volume of traffic. The section of M25 between the junctions with the M3 and M4 motorways, which is in the near vicinity of Heathrow airport, is the most heavily trafficked section. The project route which is 7 miles long is shown in Figure 1.
