|Route outline (key)|
The B5310 was a short link road in Runcorn. The road was originally unclassified; owing to its short length its history is not fully known. However, the road definitely got its number by the 1950s and was later declassified when its length was severed by the A533 Bridgewater Expressway with the growth of Runcorn New Town in the 1970s.
The road started on the A557 Greenway Road and headed northeastwards along the residential Victoria Road. It ended after less than a mile on the A533 Halton Road just before that road's bridge over the Bridgewater Canal. The western half of the road is still in existence as is the eastern end, part of which is now numbered B5155, but the road has been completely destroyed in between.
Mapping from the mid 1960s suggests that the B5310 was re-routed before becoming defunct. 1:2500 OS maps from c1964 show the east end of the B5310 remaining the same, but then turning south down Heath Road instead of staying on Victoria Road. This brought it down to the A557 somewhat further south than the earlier line. It also had a junction about half way along with the B5438, later the A558. Shortly after this, however, the A557 was re-routed along Heath Road as far as the new A533 route, and it seems unlikely that the remaining rump retained its number for long.
