M25

M25

The M25 motorway encircles London and is one of the largest ring roads in the world. It is about 117 miles long - but travelling around it clockwise covers a greater distance than travelling around it anticlockwise!

The original plan in the 1930s was to create five individual roads around London to divert traffic around the city. A new plan 1945 proposed instead that four separate roads be merged: the North and South Orbitals, the M16 North and the M25 in Kent. In 1975 John Gilbert, Minister for Transport, altered plans again and combined these four roads, creating one large road called the London Orbital Motorway or M25.
