For the modern road in Cheshire, see B6431.
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.
By the 1970s, similar scale maps show that the B6431 had been extended along Quayside underneath the Tyne Bridge, where the number seemed to spontaneously change to B6334.
During the 1980s, the route became part of the B1600.
