|Route outline (key)|
The A6180 is listed in the DfT Card Index as Romily - Bredbury. making it a short link road in east Cheshire.
The obvious route for a link between the two places is along what is now the southern end of the A6017. This road was originally the western end of the B6104 and is separated from the remainder of the A6017 by a multiplex along the A560, suggesting that a different number would be suitable.
It is not known whether the A6180 number was ever actually used as the road still had Class II status in the 1960s yet had become the A6017 by the 1980s.
