Welcome to our M25 motorway live traffic cameras webcams section. If you're planning to travel on the M25 motorway on a journey then check out many live M25 motorway traffic cameras to view the live traffic conditions on the very busy M25 motorway
The M25 motorway, or London Orbital, is a 117-mile (188 km) orbital motorway that almost encircles Greater London. The M25 is one of the world's longest orbital roads
Originally built as a dual three-lane motorway, much of the motorway has subsequently been widened to dual four-lanes in places and to a dual five-lane section between junctions 12 and 14 and a dual six-lane between junctions 14 and 15. Further widening in in progress with plans for managed motorways on other sections.
The M25 is not a continuous loop. To the east of London, the toll crossing of the Thames between Thurrock and Dartford is the lesser grade A282. The Dartford Crossing, which consists of two tunnels and the QE2 (Queen Elizabeth II) bridge, is named Canterbury Way. Passage across the bridge or through the tunnels is subject to a toll, depending on the kind of vehicle. Making this stretch a motorway would stop any traffic not permitted to use motorways from crossing the Thames east of the Woolwich Ferry.
At junction 5 near Sevenoaks, drivers continuing around the M25 in either direction must follow the slip roads. The anticlockwise carriageway continues eastward as the M26 (towards the M20); the clockwise carriageway continues towards the south coast as the A21.
The distance of the motorway from central London (taken as Charing Cross) varies from about 12 miles (19 km) near Potters Bar to 20 miles (32 km) near Byfleet. In some places (Enfield, Hillingdon and Havering) the Greater London boundary has been realigned to the M25 for minor stretches; while in others, most notably in Essex and Surrey, it is many miles distant. Major towns such as Epsom, Watford, and Loughton are within the M25. North Ockendon is the only settlement of Greater London situated outside the M25. In 2004, following an opinion poll, a move was mooted by the London Assembly to align the Greater London boundary with the M25.
The three service areas are located in the central north (Junction 23 South Mimms), south east (Clacket Lane) and central east (Thurrock). A fourth, at Cobham, is due to open in 2012.
