The
A11 is a major road in England. It runs roughly north east from London to
Norwich, Norfolk, although after the
M11 opened in the 1970s and then the
A12 extension in 1999, a lengthy section has been downgraded between the suburbs of east London and the north-west corner of the county of
Essex. It also multiplexes/overlaps with the
A14 on the
Newmarket bypass.
