The A11 is a major trunk road in England. It originally ran roughly north east from London to Norwich, Norfolk. It now consists of a short section in Inner London and a much longer section in Cambridgeshire, Suffolk and Norfolk. The lengthy section between these was renumbered as a result of the opening of the M11 in the 1970s and then the A12 extension in 1999.
It also multiplexes/overlaps with the A14 on the Newmarket bypass.
