A12 Road (England)

A12 Road (England)

The A12 is a major road in England. A trunk road for most of its length, it runs north-east from London to the coastal town of Great Yarmouth in Norfolk. The road forms part of the unsigned Euroroute E30, prior to 1985 it was the E8. Unlike most A roads, a significant portion of the A12 (together with the A14 and the A55) has junction numbers as if it were a motorway.

The 84 km section of the A12 through Essex has sections of dual two lanes and dual three lanes with eight changes in width between the M25 to Ipswich. It was named as Britain's worst road because of "potholes and regular closures due to roadworks" in a 2007 survey by Cornhill Insurance. The A12 is covered by the Highways Agency A12 and A120 Route Management Strategy.

Starting just north of the Blackwall Tunnel where it connects end on to the A102, it heads north through Bow and Hackney Wick, then northeast through Leyton and Romford, then into Essex, passing Brentwood and Colchester. In Suffolk, it passes Ipswich and Saxmundham, then follows the coast through Lowestoft before entering Norfolk, passing through Gorleston and ending at Great Yarmouth.
