The M25 or London Orbital Motorway is a major road encircling most of Greater London. The 117-mile motorway is one of the most important roads in the UK and one of the busiest. Margaret Thatcher opened the final section in 1986, making the M25 the longest ring road in Europe upon opening.

Junction 10 is the busiest section of the M25, with over 270,000 vehicles travelling through it every day. Due to the volume of traffic and the resulting queues, this area of their network has a very poor safety record and holds one of the highest collision rates across the National Highways network.
How the M25 got its name. The same principle explains the M25, which at its oldest point (the section crossing Surrey) follows the path of the older A25. These roads are all in the South East, which forms Zone 2 of the country's motorway system. This explains why they all contain 2 somewhere in their name.
