The A12 is undoubtedly one of southern England's most important roads - carrying traffic between Lowestoft and east London.
Built in 1922 as part of the Great Britain road numbering scheme, the road has played a vital role in connecting the east coast to the capital ever since.
If you live in Suffolk or surrounding areas then chances are you've used the A12 at some point - but you probably didn't you know a section of the road was closed in the 1980s and remains abandoned to this day.
