|Route outline (key)|
The B6431 was a short and obscure road in the Quayside area of Newcastle upon Tyne, as well as being a duplicate as the number already existed in Cheshire.
It first appears on 1:1250 scale maps of the area from the 1950s. At this time, it must have been a contender as one of the shortest roads in the UK: it ran merely from the A186 at City Road, down Milk Market then a short distance along Quayside before it met what was then the B1305. It may be possible that this number was, at some point, assigned to a longer route because the number was out of zone and the route was very short.
During the 1980s, the route became part of the B1600.
