This article is about the current B5075 to the north of Northwich. For the original B5075 in Crewe, see B5075 (Crewe).
The B5075 is a short link road running northeast of Northwich. The road was originally unclassified but had gained its number by the early 1930s.
The road originally started on the A556 Witton Street and headed north along Old Warrington Road, passing between Ashton's and Neumann's Flashes (lakes caused by subsidence due to salt mining). The northern end of this road has now been closed so the present B5075 starts at a roundabout to the east of Northwich town centre, where it meets the A559 and B5082, and heads north along New Warrington Road across reclaimed industrial land. Ashton's Flashes, to the left, have largely dried up. Old and new roads meet at a point that is not obvious on the ground, after which the road reaches Marston.
After passing the former Lion Salt Works (now a museum) we cross the Trent & Mersey Canal and pass a couple more flashes and a cemetery. We now cross the fields to reach Higher Marston and a triangular junction on the A559, where the road ends.
