TheA102 is aroad starting inClapton, east London, and ends by merging into theA2 road just south of theSun in the Sands roundabout inBlackheath, south-east London. The total length of the road (including both sections) is approximately 4.4 miles (7.1 km).
The section of the former A102 now designated as the A12 and the two sections of the A102(M) were all constructed in the mid- and late-1960s as part of theEast Cross Route which was intended to be the eastern section of theRingway 1 (also known as the London Motorway Box), an ambitious and controversialGreater London Council plan to surround London with high speed roads – known as theLondon Ringways – which was eventually cancelled.
When the A12 extension was opened throughWanstead,Leytonstone andLeyton to meet the north end of the East Cross Route at the Lea Interchange (and prompting theM11 link road protest), the northern section of the A102(M) and the A102 as far south as the A13 were renumbered A12. The southern section of the A102(M) was reclassified as a general purpose road whenTransport for London was given control of trunk roads in Greater London in 1999.[citation needed]
